Acorn Changelog

What's new in Acorn 7.4.4

Feb 23, 2024

New Stuff:
Super Resolution ML resizing. This new option in the Image ▸ Resize Image… menu item lets you increase the size of your image up to 4x using Machine Learning. Or is it AI now? I don't know and don't care, but it's pretty awesome! It packs a ton of crazy statistics and math into a simple little dropdown menu. Give it a shot for your photos, you won't be disappointed. (Super Resolution is for MacOS 12 or later only).
Stroke Selections! Finally. You can now perform this long requested feature via the Select menu, and even works with Magic Wand selections (MacOS 11 or later only). Change your stroke size, blending, anti-alias or not, and even add a fill.
You can now convert Magic Wand selections to shape layers. This is also super awesome! If you've got a fun outline of something that you want to convert into a shape, this is the way. (MacOS 11 or later only).
New "Simple Film Grain" filter, which will add a grainy overlay to your image. Just like Grandpa's photos used to have.
The Text Palette now shows what the font looks like in the font pop-up menus.
Holding down the backslash key ('') will temporarily switch off any layer filters you have on selected layers.
Neat new trick with the Shortcuts Crop action: If you choose "Custom" as the position and put in negative values, the canvas will expand instead of shrink. A negative X value will increase the size on the left, Y on the bottom, Width on the right, and Height for the top.
Various little improvements to the File Info window, including shortcuts (Command 1-4) to switch between the sections.
Other:
Double clicking on a non-bézier shape with the anchor select tool will now convert it to a bézier shape (previously this only worked with the move tool (shortcut key 'v').
The tool palette will now dim tools that you can't use in modal operations (such as when cropping, scaling and rotating, and similar operations).
A new Shortcuts action to open images in Acorn.
Various improvements to Acorn's SVG importer.
Tweaks to the Image Resize window.
Tweaks to the Image Meta Data window (which you can get to from the File ▸ File Info… menu).
The AppleScript command do filter name "Your Filter Preset Name Here" will now work with filter presets as well. This is in addition to the call filter preset with name command. There is a story behind this. It isn't very good.
Various little fixes in the French localization, with a big thanks to Corentin Cras-Méneur for finding those.
Acorn is now putting PNG data on the clipboard when using ⌘C in addition to TIFF data (it was previously only doing this for Copy Merged - ⌘⌃C).
Acorn is no longer declaring itself as the default editor for a couple of file types, including HEIC (sorry about that!).
Acorn now shows a warning when trying to open up a EPS file on MacOS 13 or later (Apple has unfortunately removed support from MacOS).
Fixes:
Fixed a regression from Acorn 6, where you could drag and drop layers to the + button in the palette to duplicate it, as well as dragging it to the trash button to delete it. So those work again, which is awesome and feels nice.
Fixed a bug where blendable layer filters wouldn't always blend correctly when you viewed your image zoomed out.
Minor Export window improvements and localization fixes.
Minor text tool and color picker interaction fixes.
Fixed a drawing issue where the canvas was at wackadoodle zoomed out sizes (thanks magic mouse), and trimmed up bitmap layers were leaving little pixel remains behind when you moved the layer with the arrow keys.
Fixed a problem where adding a Hue Shift shape processor without changing its default values would cause problems when trying to save your image in the Acorn file format.
Fix for a crasher on some Macs when attempting to create Metal Contexts.

New in Acorn 7.4.3 (Sep 26, 2023)

Little New Features:
The selection palette now lists the number of pixels you have selected!
The trick for croping a layer without resizing a canvas will now work when you have multiple layers selected. (The trick is to hold down the option key when finishing up your crop. It's neat, try it! You can quickly cut cruft out of your layer(s) without having to change the size of your image). Cropping a shape layer will also remove graphics outside the crop bounds now.
New Auto Level / Straighten action in the Command Bar, and when holding down the option key when choosing the Layer menu (as an alternate to "Auto Enhance"). This will tell Acorn to take a good guess at leveling out your picture.
Super Minor Stuff:
When importing SVG files, polygon tags are read into bezier shapes.
Layered screenshots now include the cursor.
When taking a layered screenshot with a specific application defined, the menu bar is now included.
The crash report checker would always check if a new version was available, even if you had the option to check for updates turned off. This oversight has been corrected and the programmer responsible given twenty lashings.
Bug Fixes:
Fixed some drawing issue which appeared on MacOS 14 (Sonoma).
Fixed a problem where the system color picker would try and match color profiles between two different images which didn't match, and go a little nuts.
Fixed a problem where sometimes setting the box fill color of a text shape would also change the text fill color as well. Whoops, sorry about that. It's fixed now though!
Fixed a bug where you'd get a warning when trying to save a file in .acorn format which was previously in .webp.
JavaScript Stuff:
Acorn now comes with a little console window you can open up via the Command Bar (it's named "Console"). Any output from JavaScript plugins will go here (via `console.log()`).
Weird Hidden Experimental Stuff:
I'm playing around with the idea of automatically removing the file type and last saved location to flat files (such as PNG or JPEG) when adding layers to them. This is for cases where you open up a PNG, add text, and then want to save it as a .acorn file (mostly automatically) because you'd love to preserve the layer data and saving it right back to a PNG will ruin that idea. And Acorn throwing up a dialog box telling you this kind of gets in the way. So here's a hidden pref (copy + paste into the Terminal app and press return) to enable it:
defaults write com.flyingmeat.Acorn7 updateFlatToAcornFormatWhenAddingLayers 1
If you try it out, I'd love to hear how it's going for you.

New in Acorn 7.4.2 (May 9, 2023)

New in Acorn 7.4.1 (May 2, 2023)

New in Acorn 7.4 (Apr 28, 2023)

New Stuff:
Big Clone Tool Improvements. The clone tool has been updated to give you a preview of what your brush stroke will look like before drawing. In addition, a new on canvas widget is available which lets you know exactly where the source is coming from, which you can move around to pick a new clone source. Pressing the option key to reassign a clone location still works as usual. And just like the previous iteration of the clone tool, you can clone from other images or layers into any bitmap layer.
Corner Radius for Bézier Curves and Stars: Bézier curves where two straight lines join can now have a corner radius! This is pretty cool, and a great way to round out a shape for a logo or for a sign. The star shape also gets to join in on the fun.
Super accurate colors via floats in the color palette: What's the point of having access to over 281 trillion colors (79 octillion for 128 bit images!) if you can't actually set them with super decimal precision? Now you can with Acorn's custom color picker. Switch between 8-bit, Percentage, and now 32-bit Float for displaying and setting your RGBA values.
New Command Bar actions: "Hide All Layers" and "Show All Layers"
New AppleScript command "do command bar action" which will do a fuzzy string search of the given command, and then invoke it.
New AppleScript command "append filter", which can be used to add a non-destructive Core Image filter (with optional parameters) to the currently selected layer.
Fixes:
Fixed an SVG import problem where shapes enclosed in an "defs" group were being rendered incorrectly.
Fixed a problem where the default selected tool might not be highlighted correctly when opening a new window when you have the preference "Float inspector palettes in windows" enabled.
Fixed an issue with the Photos Editing extension where it might not work correctly on MacOS Ventura.
Fixed an issue where the setting a non-auto line height could cause clipping of text.
Fixed some cases where tooltips were showing up over the cursor when the pref "Hide cursor tooltips" was enabled.
Fixed a problem where you changing gradient in a text wasn't working correctly.
Other:
Updated the WebP libraries so they work better on Apple Silicon Macs.
EPS files are now opened up like PDF files, where you can set the background color, DPI, and pixel dimensions of the image before rasterizing it. If you prefer the previous behavior, you can hold the option key down while opening an EPS file and Acorn will use the old workflow.
The Shift-G shortcut will now select the fill tool (for Photoshop compatibility). Shift-S will select the clone tool.
Updated Polish localization courtesy of Leszek Klich.
Holding down both the Option and Command keys at startup of Acorn will give you the option to reset your preferences (your registration information will be retained).

New in Acorn 7.3.3 (Feb 15, 2023)

New in Acorn 7.3.2 (Jan 27, 2023)

New in Acorn 7.3.1 (Dec 6, 2022)

New in Acorn 7.3 (Oct 25, 2022)

New:
New "Snapshot" and "Snapshot Reblend" filters, which will take a copy of your image and then re-blend it back in your filter chain. This is awesome if you want to make some custom shadows or have other crazy ideas.
New "Custom" filter, which gives you a 5 by 5 matrix to apply a custom convolution to the pixels in your image which you can use to make custom blurs, sharpens, embosses, and more. Presets are also provided for you to play around with.
Added a bunch more blend modes to the generator filters, so now you can have all kinds of fun making your gradients and checkerboards super funky.
Updated Spotlight layer filter, which allows you to control the shadow/darkness color.
New "Paste Text Without Formatting" Command Bar action which will be enabled when editing a text area.
New "Select All Layers" Command Bar action.
The new image window will now show a preset for all attached displays instead of only the main display.
New French localization compliments of David Lacan.
Other:
Minor tweaks to the Web Export window (copy to clipboard icon and Save… button).
QOL improvement for folks who have floating tool windows: the tool palette now has a tittle so you've got a bit more room to grab a hold of the top of the window to drag it around.
QOL improvements for MacOS 13 Ventura.
Acorn's SVG importer now correctly handles line elements.
When pressing the delete key in text boxes, Acorn will no longer try and size your box to fit (we heard from folks that you don't like this, so we'll try something new).
Quality of Life fixes for the Scale and Rotate palette.
Acorn will now warn you when you're attempting to scale a layer to something that's unreasonably large.
There's a new hidden pref to not hide the filter HUD when you're manipulating it on canvas. You can enable it by pasting the following into the Terminal app and pressing enter:
defaults write com.flyingmeat.Acorn7 hideHudOnMouseDown 0
To undo the setting, paste the following into the Terminal app and press enter:
defaults delete com.flyingmeat.Acorn7 hideHudOnMouseDown
The "Alignment & Boolean" palette has been renamed to "Align & Combine". Hopefully this will help people understand what's going on under there a bit better.
The scale and rotate tool is better at detecting if the edges of your selection are opaque or not, and then doing some fancy moves to make sure the edges stay sharp and crisp when resizing.
Acorn can no longer read or write LIFT images, something which has been disabled for a while now.
Fixed:
Fixed an issue where it was very, very hard to get rid of a gradient on a text box.
Fixed a problem where you couldn't delete a filter preset from the Menu Bar.
Fixed some instances where the system color picker would not come up when you had the "Use system color panel" Fussy Stuff preference set.
Fixed a problem where masks were not being applied correctly when exporting as PDF.
Layout fixes for the blur and sharpen brush palettes.
Fixed a problem where moving anchors in multi-run bezier paths might move the wrong endpoint.
Fixed a problem where doing a Simple Affine scale without keeping the aspect ratio wouldn't do the right thing.
Fixed some UI problems with the generator filters' blend mode popup.
Fixed a problem where Acorn might mess up a merge layer down if the top layer had a Mask blend mode and the frame of the layer was smaller than the bottom layer.
Fixed a problem where Acorn might crash when opening up certain PSD files.
Fixed a problem where the color sampler loupe would not update correctly when zooming the canvas in and out.

New in Acorn 7.2 (Jun 19, 2022)

New:
Shortcuts support: Apply filters and filter presets, crop, flip, resize, rotate, auto enhance, change color profiles, new image from clipboard, and trim images. We're also taking requests as well so if there's something you'd like to see, let us know!
New text box vertical alignment options: top, middle, and bottom.
New "Auto Enhance" item under the Layer menu for bitmap layers. This action will improve skin tones, saturation, contrast, shadows and repair red-eyes or LED-eyes.
The Histogram filter (which shows a histogram for the current layer) now has a "High fidelity" checkbox. This uses all the pixels in the layer to calculate a histogram, at the cost of being a little slower.
New option in Layer Export where you can crop a layer's bounds to the canvas size.
New "Lossless" option when exporting images as WebP.
New "Matte" filter which will add a colored background to a layer with any transparent areas.
You can now choose "Bicubic" as a scaling algorithm when resizing an image.
New "make new document from Clipboard" AppleScript command.
New Command Bar actions: "New Image From Selected Layers" and "Delete Hidden Layers".
New layers list contextual menu: "New Image From Selected Layers".
Fussy Stuff:
Double clicking a label in the RAW Import window will reset its corresponding slider / value. This is similar behavior to what happens for the text palette labels (if you were unaware of that, now you know!).
New Fussy Stuff preference to always open up windows to their maximum size.
Auto-scroll is re-enabled when moving bitmap layers around on the canvas.
Other:
The "1Bit" filter now has an option to remove transparency from pixels that aren't 100% opaque.
Text palette settings will sync between windows when each image has it's own palette connected.
Added a "Tablet pressure changes opacity" option in the brush palette.
Acorn will no longer warn you about the size of your image (if it's really big) when resizing it to be something smaller than it currently is (really really big).
The Generate Shapes processor now has options to enable/disable stroke and fill when making new shapes.
When merging a layer down, the top layer's name is now used for the combined layer's name.
Various tweaking of the Automator actions so they work better with MacOS 12 Monterey. If you're using any in a production environment, make sure to test them in case any changes had an impact on your workflows.
Bug Fixes:
Fixed a problem where you couldn't drag a layer to the Trash in the Dock to delete it.
Fixed a problem where angle fields for negative numbers in the filter palette were not formatted correctly.
Fixed a problem where the color loupe might not work from the Fill… window.
Fixed a problem where certain felt and watercolor brushes couldn't be used as an eraser.
Fixed an problem where the "Cumulative" option of the Rotate shape processor wasn't saved with .acorn files.
Fixed an issue where the Image menu might take a second to come up on some ARM Macs with weird video cameras attached.
Fixed a possible crasher with when picking a color from the Fill… dialog.

New in Acorn 7.1.3 (Feb 9, 2022)

New in Acorn 7.1.2 (Dec 17, 2021)

New in Acorn 7.1.1 (Oct 29, 2021)

New in Acorn 7.1 (Sep 1, 2021)

New Stuff and Changes:
The Export window now has a share toolbar item, so you can send your exported image direct to Mail or other apps (10.15+).
The Export window has a new "Copy to Clipboard" button in the lower left corner.
Added support for Mozilla's MozJPEG encoder in the Export window (and also available via AppleScript via the "web export" command).
Acorn is a lot faster at opening up animated GIF and PNG files with lots of frames. It also uses way less memory when doing so now on your M1 Macs.
The sheet for adding filters is now a popover. This is awesome if you're on MacOS 11 or later and you're tired of seeing your image being dimmed out when you bring it up.
When using the rotation dial in the shape inspector, it will always round to nice whole values. But if you want super precise values when using the dial, hold down the option key.
New fussy pref: "Use PDF import window with New from Clipboard". This is awesome if you have PDF data on the clipboard and you want to get a preview of the image or change the DPI of the rasterized PDF or even give it a background color.
The action menu in the filters and shape processors inspector will now let you enable and disable all filters. In addition, the controls for the filters will become disabled if you turn off their visibility.
Updated the fuzzy matching algorithm for the Command Bar so it gets slightly better results.
If you have Acorn's color picker up, Command-Shift-C will close it (or bring it back up if it's already gone. It acts as a toggle now!)
Double clicking on a color in Acorn's color picker will now dismiss the color picker.
Updated the iOS presets in the new image window.
The AppleScript paste command now returns a layer object when the clipboard contains something that'll make a new layer.
Bug Fixes:
Made some tweaks to how Acorn's color sampler works when picking images out from the screen, where previously things might get wonky with certain display setups.
Fixed a problem where Export option for a background matte wouldn't work for Animated GIFs.
Fixed a problem where a font name in the font popup for background windows might change on you when it didn't make sense to.
Fixed a problem where the "Lock dimensions" setting wasn't saved along with a crop preset.
Fixed a problem where selecting a gray color profile on export would remove the alpha channel from your image.
Fixed a problem where the "Fill expansion with color" option when resizing a canvas could add just a bit _too_ much color to your image.
Fixed a problem where painting might not show up correctly on certain layers after moving them around a bit.
Fixed a problem where copying a layer to a mask could remove the original layer if the original layer and mask were on the same row, resulting in a sad outcome.
Fixed some problems where changing the text color might not work.
Fixed some problems where the Touch Bar wouldn't show the right controls for the Pencil tool.
Cleaned up some shape layer handle drawing when resizing multiple selected shapes.
Fixed problem where duplicated layers would get a blank name.
Fixed problem where histograms weren't showing up on 10.15.7 after Apple's Security Update 2021-002 Catalina was installed.
Other:
Shape shadow offsets no longer clamp to 200/-200 pixels.
Cleanup of some tool icons.
The zoom to fit shortcut is now 8% more accurate.
Tweaked the way histograms are drawn a little for the Levels filter.
Previewing some RAW files should be faster now.
The slider for the Exposure setting in the Dodge and Burn brushes now looks and acts like the other sliders in that inspector.

New in Acorn 7.0.3 (Apr 29, 2021)

New in Acorn 7.0.2 (Apr 5, 2021)

New in Acorn 7.0.1 (Mar 23, 2021)

New in Acorn 7.0 (Mar 18, 2021)

New Stuff:
An all new interface:
Acorn now sports a unified window with a matching toolbar. Gone are the floating palettes everywhere and getting in your way. Palettes are now inspectors and can be brushed away by pressing the TAB key, and brought back the same way. Acorn also adopts many new MacOS Big Sur conventions to make it look and feel like it belongs on a Mac. If you prefer the previous behavior where inspectors are in their own windows, there is a preference to enable that.
Speaking of tabs, Acorn has a new preference for opening up images in tabs. So now you can gather all of you open images under a single window.
Über Export:
A new export workflow gives you options for specifying a color profile (like CMYK or Gray), more formats to save as (now including WebP!), precise file size of your export, and a live preview even for PDFs. This new workflow builds on and merges the previous Web Export window, but now with tons more options.
The File ▸ Share menu items also work when the Export window is up. So if you're just interested in mailing an image off to a friend after resizing it a little in the export window, this is a great way to go.
Animated GIF export:
This is a new option is part of the new export workflow, and allows you to export all the layers in an image as an animated GIF. You can open up existing animated GIFs, change a single frame or apply filters to a range of frames. You can then export your GIF with the original frames per second or speed or slow it down.
New color picker:
We built a brand new color picker from the ground up which is super accurate, supports wide gamuts like Display P3, uses 64 bits for super accurate color values (and representing over 281 trillion colors), lets you adjust RGB and HSV values without switching modes, and handles your various color profiles perfectly.
Speed:
We've always got your eyes on ways to make Acorn even faster. This time around we managed to make Flood Fill, Instant Alpha, and Magic Wand multithreaded and up to 3x faster. Filters have also been fully optimized for Metal on Apple Silicon and Intel Macs. We've also made tweaks to the Metal pipeline which should make Acorn even more responsive than ever.
Universal Build:
We'll say it again in case you missed it, but Acorn is now full optimized for Apple Silicon Macs. It's fast.
New Command Bar:
Using the File ▸ Command Bar menu item (shortcut key ⌘⇧O) will bring up a little text window you can type in to find menu commands or other hidden commands. You can also search Acorn's help documentation with this.
Type "h" followed by a space and then a help topic to only search documentation. For instance, if you typed "h crop" it will return all documentation related to the crop tool.
There are some entries which do not show up in the menu bar, but which can be useful: Toggle Dark Aqua, Fill Layer, Fill Layer With Stroke Color, Feather (10px radius), Use Pixels for Ruler, Toggle Stroke/Fill, Change Canvas Background, Capitalize/Lowercase/Uppercase Text.
RAW import improvements:
You can now Save presets for your RAW images. We've also rebuilt the import preview allowing you to zoom in and out of your image, all powered by Metal of course.
New Navigation & Zoom Inspector:
Get an overview of your whole image, at any zoom level. Move the viewfinder in the inspector to change what you're looking at on your canvas. Use the histogram as an overview for the color balances in your image.
Perspective Fix & Crop tool:
This cool little tool will help you draw a grid on the canvas which you can use to help fix images where there are problematic perspective distortions.
New Fussy Preference: "Use short file extensions (jpg & tif)". Now, I know what you're thinking. You're thinking "Really? Really this was added as a preference? This is what time was spent on?" Well some of you are very, very vocal about this. And for years I've tried to appease you by pointing out that this is what MacOS does by default, but still… you were never happy. But now, well I hope this preference will make your day a little better and you can focus your energies on sending me emails about other things you wish were different in Acorn. I wonder what those will be?
Good Things Got Better:
Double clicking on a bitmap layer with the move tool will begin a scale and rotate transform for the layer. This also works with selections! If you have a selection on a bitmap layer you can switch to the move tool (or hold down the command key with a selection tool active) and double click within the selection to begin transforming it. You can press the esc key to exit the transform and undo any changes, or press the enter key to commit it.
You can now set a background fill color when resizing your canvas. If you have more than one layer, then Acorn will use the bottom bitmap layer in your image. If there is a layer on the bottom that is not a bitmap layer, then the fill options will not be enabled.
The brush palette now has the option to set spacing for brushes. Previously you could only do this in the Brush Designer window.
If you use the contextual on a text box while its shape layer is active, you'll get a new menu item to begin editing that text. (This also works for Circle and Path text as well).
Flipping layers horizontal or vertical is more consistent between shape and bitmap layers.
Web Export now has an option to include your image's DPI.
When saving a TIFF file, Acorn will now use the original compression settings for that file, instead of defaulting to LZW.
When saving as a TIFF file, Acorn now gives you options for the compression: LZW, None, and Packbits.
New preference for wether or not to change the canvas background color during full screen.
New Rotate filter, which works on your image and generated filters. It's non-destructive, so you can always go back and change the angle later on.
Shape Layer Stuff:
New: Text boxes can now have a background color and stroke. The text inspector now has dedicated swatches and toggles for text stroke and fill.
You can option-click the p icon in the layer list to disable shape processors. And when this happens, you can interact with shapes on the layer as well (where you previously couldn't when you have shape processors going). Disabling all the shape processors will also do this, but it can be a bit more tedious going this route.
You can extend an open bezier path by holding down the shift key with the bezier tool selected, and clicking on the end of a bezier path.
Text boxes in shape layers got a bit of an interaction makeover. Editing and selecting text boxes should feel more natural and easy now.
More obvious selection bounds when trying to choose a shape to select.
Added a little extended handle on selected shapes to rotate them directly from the canvas. Previously, this was done by some invisible handles near the corners (which are still there in case you loved those!).
The "Arrange Shapes in a Circle" and "Rotate" processors now let you assign fractional values for the angle and spacing attributes.
Tweaks to the Shape Creator Processor, which now allows you to create circle shapes with a radius of .5. This is awesome if you're looking to make a star field of some sort. This processor will also automatically turn on fill for shapes, if the shape palette has both fill and stroke turned off.
Other Notable Quality of Life Improvements and Miscellaneous Things:
Acorn plays nice with the System Preferences General settings for opening windows in tabs and such.
New Fussy Pref: Copying selection trims transparent pixels.
New fussy preference: "Use system color panel", which uses the system color panel. You can also hold down the command key when clicking a color well to temporarily use the opposite of whatever this preference is set to.
Double clicking on the canvas zoom scale slider will zoom the canvas to 100%.
You can now change the color of the canvas background via the canvas's contextual menu (or the command bar).
Pressing the '`' (back-tick) key when using a brush or pencil tool will turn it into a temporary eraser. Previously you would hold down both the command and option keys together to get this behavior, but another big image editing app uses '`' so I figure Acorn should too.
If you have a color on the clipboard, pasting it into a bitmap layer will now fill it with the color. If you paste this color into a shape layer with selected graphics, it will set the fill color for those graphics. (Did you know: you can use the color picker loupe to put a color on the clipboard by pressing the 'c' key).
The layers list was completely rewritten to use modern APIs. Let us know if you notice any chance behavior!
The Hard Mix blend mode has been changed to more match the industry standard for this compositing operation.
Quartz Composer filters are no longer supported.
Using Edit ▸ Copy when multiple layers are selected will now place a composite of the selected layers onto the clipboard, as well as respecting the current canvas selection.
Auto-select layer tweaks: If you have the preference "Auto-select layers" under the Advanced tab turned on, Acorn will automatically select a layer for you when you use the move tool to click down on the canvas. If you hold down the command key, then this setting is ignored. Conversely, if you have it turned off and you hold down the command key Acorn will auto-select a layer for you.
Smart layer export settings will now reposition themselves when a layer or image is cropped or resized or canvas flipped.
Fixed some instances where you could modify a locked layer.
You can no longer rotate the canvas if there are locked layers.
The ruler now shows a accent color when you're moving selected shapes around, representing the selected shape bounds.
Acorn will no longer highlight shapes when you're hovering over a guide.
You can now drag and drop an app onto Acorn to open up an image with the app's icon.
Acorn will now show the startup window on reopen events if no windows are open and if the preference "Show startup window on launch" enabled.
Copying a selection on a bitmap layer now applies the mask before the image is written to the clipboard.
Holding down the option key when selecting a color profile from the Preference's default Color Profile for New Images popup will show the full path for the profile names. This is handy if you have multiple copies of sRGB installed, or any other profiles, and you'd really like to make sure you know which one you're using. This also works for the Image ▸ Color Profile… sheet, as well as the RAW Image import window.
Improved pasting of multiple objects from one shape layer to another shape layer in another document.
Acorn will no longer highlight shapes when you're hovering over a guide.
Removed the pref for the "old brush engine". You can use the default 'defaults write com.flyingmeat.Acorn7 useBrushEngine5 1' to bring it back if you really really want it.
New Fussy Pref: "Zooming a window fits to current canvas".
The exposure filter now uses percentages.
Acorn will now keep you from dragging layers out of locked groups.
Fixed a problem where various tile filters weren't updating the whole layer when you drew on them
Made the filter sheet picker a bit taller
You can now make the grid spacing up to 10,000 pixels wide for the canvas. The spacing slider also uses an exponential transformer now, so you can get way larger values now.
The canvas scale slider now uses a bit of mathematical magic to make it easier to zoom waaaay in and out.
Holding down the control key while dragging a canvas guide around will temporarily turn off snapping (and this trick works with most objects on the canvas too).
Take layered screenshots is now on by default when using Acorn's screenshot hotkey.
If a brush cursor is less than 5px wide on a retina display, or less than 3px on an @1x display, Acorn will now show a little crosshair because those brushes are otherwise too small to see.
You can no longer mess with layer filter settings if a layer is locked.
The export window will now auto-select the original color profile for an image, even if it was converted from a gray to an RGB color space. This is awesome if you open up a gray profile image (which Acorn doesn't support for editing normally) and you want to save it back out as the original.
Changed the screenshot shortcut key to Command-Shift-7, so it no longer interferes with the system one for taking screenshots of the Touch Bar.
Changed the default radius of the color loupe to 200pts (down from 400). If you would like the larger size back, you can paste the following into Terminal.app and hit return:
defaults write com.flyingmeat.Acorn7 colorLoupeRadius 200
Acorn no longer supports plugins written in Python.
Scripting:
The JavaScript interface has changed quite a bit. The CocoaScript / JSTalk preprocessor has been deprecated and the [] syntax is no longer encouraged. In fact, your script will fail using this syntax unless it ends with .jstalk or .coscript. JavaScript files that end with .js will no longer be preprocessed. (Though there is a hidden preference to always enable it: defaults write com.flyingmeat.Acorn7 preprocessJS 1
The Cocoa Script / JSTalk bridge has been replaced with FMJS. If you have complicated JavaScript files, you might need to rework them a little bit.

New Shape Processor Filters:
Hue Shift. Shift the hue of your shapes by a configurable amount. (Available for MacOS 10.13 or later).
Flip. You can flip your shapes vertical or horizontal, using the flip axis of either the canvas, processed shapes, or the shape itself.
Fill, which lets you change the color a shape fills with (and if it fills at all).
Stroke, which lets you change if a shape draws a stroke, how wide it is, and the color.
Blend Mode, which will change the blend / compositing mode for all processed shapes.
And finally, if you double click on the canvas when Shape Processors are active, it will now bring up the Shape Processor palette.
Other New Things:
The Mask to Alpha filter has a new invert invert colors option. Normally mask to alpha will convert the black areas of your image to transparent, and the white to opaque (with gray somewhere in-between). With the new Invert Colors option, Mask to Alpha will now convert the white areas of your image to transparent, and keep the black opaque. This is great if you are scanning line line drawings from your own artwork, and want to make the backgrounds transparent.
Minor Stuff:
Acorn does a bit of database cleanup now by default when saving in the Acorn image format, which will result in smaller files in some cases.
Color profiles are now included with PSD exports (thanks to the folks at The Iconfactory for the patch!)
When resizing your image to something rather larger than normal, Acorn will ask to make sure that's what you wanted to do. (Acorn already did this for new documents, but it's super handy when resizing or changing your canvas size as well).
Improvements to PSD export:
Pasting an image into the New Image window will create a new image with the contents of the paste. This has always been the case. The new thing is that any open New Image windows will now close.
The Save Panel brought some old tricks back! If you Save a new image, or Save As… an existing image and enter the file name and type out a changed extension, Acorn will notice and auto-select the right file type from the format popup. This had been broken on 10.15 and sandboxed versions of Acorn previously. But no more! (Hat tip to Rich Siegel for the workaround).
The Edit ▸ Fill… command now picks the right fill color to use (instead of possibly the stroke) from the tool palette color well. (Also- in case you didn't already know, pressing Option-Delete will automatically fill a bitmap layer with the current fill color. It's a nice shortcut to have around).
Minor and mysterious QOL fixes involving fonts, color profile sheets, pixel tool drawing, and redrawing on 10.15.
Bezier shapes now draw their outlines and handles when manipulating anchor points and their associated handles.
Removed the 'Mix' filter.
Fixes:
Fixed a problem where the File ▸ Revert command might not set the canvas dimensions to the correct dimensions.
Fixed a problem where the text selection drawing would be pretty wonky if you had changed the line height of a text box.
Fixed a crasher where the OS would tell about non-existent color profiles, and then Acorn tried to use these ghost profiles.
Fixed some issues where applying a font to text where there are no valid glyphs would leave the font popup button in an interesting state.
Fixed a problem where the eraser tool might not restrict itself to selections.
Fixed a couple of little brushing issues with the tablet and blend modes.
Fixed a bunch of issues where SVG parsing would fail with complex paths. Also added support for the line-cap attribute when importing SVG files.
Fixed a problem when exporting all layers as SVG.
Fixed a problem where dragging SVG files onto the canvas wouldn't import the images correctly.
Fixed an issue with web export windows not displaying correctly for 16bpc images on 10.15.

New in Acorn 6.5.3 (Nov 21, 2019)

New in Acorn 6.5.2 (Oct 18, 2019)

New in Acorn 6.5.1 (Oct 8, 2019)

New in Acorn 6.5 (Jul 12, 2019)

New:
The Clone tool now has an opacity option.
Crop improvements: You can now set the DPI of an image while cropping, and alignment guides now appear when rotating your image in a crop.
The Perspective Transform command has a new option in the palette to show / hide the grid. It also gets a new palette that shows up when invoked.
Feathering selections: The Select ▸ Feather… menu item has been removed and you can now control the feather on a selection right in the selection palette.
End caps for bezier paths: You can now change between round, square, and butt end cap styles for bezier paths. These new options are right under the join style in the path options section of the shape palette. Also, it's now easier to see the selected state of the line join and cap styles.
You can now use the anchor select tool to drag and select multiple anchors.
New Image Panel improvements: We've increased the accuracy when changing from one unit to another (ie- inches to centimeters) as well as added an option to view the resolution field as pixels per inch or pixels per centimeter.
The PDF import window now shows the pixel dimensions of what your new image will be (and updates accordingly when you change the DPI)
We've added a new advanced preference which tells Acorn to load 3rd party Image Units.
Changes:
New Polish Localization courtesy of Leszek Klich.
Better support for editing images from Bear.
Tightened up the pixel edges a shape will snap to on creation (specifically bezier path or rect shapes).
Adjust a text box to have a non-zero line height will no longer clip the top of the first line (for new text boxes only; existing text boxes will keep the old behavior).
The blinking insertion point for text boxes and paths is a little bit thicker now.
Kerning is now on by default for new text boxes (previously it was disabled). You can turn kerning off by editing and selecting the text, then using the Edit ▸ Font ▸ Kern ▸ Use None menu item. Additionally, the Command-Option-[ and Command-Option-] shortcuts can be used to tighten and loosen the kerning on selected text (while editing it).
Improvements to how the aspect ratio is kept when placing a crop preset on the canvas and then swapping the orientation with the 'x' key.
No longer showing a modal dialog box when a trying to change a locked layer. An in-canvas notification is now shown instead.
Web Export now lets you explicitly set the quality of your image when exporting, in addition to the already existing slider. The quality setting lets Acorn know how much compression to use when exporting your image.
The DPI for certain presets have been increased from 72 to 300 dpi.
Text padding changes. Prior to Acorn 6.5, text boxes had a 5 pixel inset which would make glyphs show up 5 pixels to the right of where the logical location of the text box was. This meant that when you left aligned a text box below a filled box, the starting glyph wasn't exactly where you'd expect it to be. In Acorn 6.5, new text boxes are created with a padding of 0 pixels so alignment will always happen as you'd expect. Existing text boxes keep the 5 pixel inset for compatibility's sake.
The default new document size has been changed to be whatever half the size of your display's pixel dimensions are.
Acorn has a new hidden pref for auto-saving of all file types, not just Acorn:
defaults write com.flyingmeat.Acorn6 autosaveNonNativeImages 1
If you're using this on lossy file types like JPEG, your image will degrade over time because each time you open and save your image, details are lost.
Fixes:
Fixed a problem where Smart Layer Export wouldn't work when an extension was not given in the file name.
Clearing the document edited state when using the Revert menu item.
Fixed a problem where adding a control point to the curves filter wouldn't show up right away.
Fixed a problem when using the pencil tool on 10.13 and later with the blend mode set to copy.
Fixed some little issues with Automator actions.
Fixed an issue where undo wouldn't always work when moving control points for a bezier path.
Better selections in text boxes when line and paragraph spacing are non-default values.
Fixed an issue where empty windows would sometimes come up when you launched Acorn.
Fixed a problem where setting the paragraph spacing to 0 while editing a text box would sometimes fail.
The File ▸ New from Selection command now copies over the correct DPI from the copied image.
Fixed an issue where the DPI of your image could change when using the Image ▸ Resize Image… menu item, and you didn't really want it to.
Fixed a problem where the Reselect command wouldn't work.
Fixed some issues when setting specific kerning on characters.
Fixed a problem when exporting an image as PDF when a shape layer had a layer filter turned on.
Fixed a possible memory leak when exporting via Web Export.
Fixed a minor bug where the cursor wouldn't update when you cleared a selection by pressing the ESC key.

New in Acorn 6.3.2 (Mar 7, 2019)

New Masking Things:
Portrait Mask support! If you have an iPhone running iOS 12 which takes Portrait photos with the camera, Acorn will now detect and open up the Portrait Matte as a mask for the image! You can then enable this mask to block out the background and add fancy backgrounds or custom blurs for your image.
New menu item to move a layer mask to a regular layer. Select the layer with the mask, hold down the Shift and Option keys, and choose the Layer ▸ Eject Layer Mask menu item. This menu is also available under the action menu of the main palette window, and in the canvas contextual menu.
Drag and drop out layer masks! If you have a layer mask selected, you can now drag it out of the layers list into it's own layer or even move it to another layer mask. Hold down the Shift key to move it to a layer that doesn't already have a layer mask. Hold down the option key to make a copy of it.
Hold down the shift key when clicking on a mask to toggle it on or off.
Did you know? You can hold down the option key when clicking on a mask to toggle direct visibility of it. A normal click on the layer mask again (or any other layer) will turn it off.
You can drag and drop a mask onto the trash icon to delete it.
You can drag and drop a mask onto the + icon to copy it.
When a mask is selected, pressing Command Delete will remove it.
Exporting layers will now export the mask as well (via the File ▸ Export ▸ Export All Layers… menu item). And you now have the option to apply the mask on export.
New Brushing Things:
Acorn has a brand new brushing engine with much improved performance when running on MacOS 10.13 or 10.14 Mojave.
A whole new category of "Basic Round" brushes ranging from 1px in size up to 5000px.
Four new hand crafted bristle brushes.
Saved brushes now have an opacity setting that can go along with it.
The brush palette now has options for setting flow, softness, and the blending of the currently selected brush.
Indexed PNG Images in Web Export:
Reduce the number of images used for PNG export, and save in file size! When exporting as a PNG you now have the option to "Index PNG Colors" which will reduce the bit depth of your image while also reducing the file size. Make an image that's 90% smaller than the original.
Improved PDF Export:
Instead of rasterizing everything to a single bitmap layer which is then turned into a vector-less PDF, Acorn will now mix vector layers with bitmap layers. What this means is that you can have a fancy background imported from somewhere, and have text on a path (or circle) and other shapes that aren't turned into bitmaps which can look bad at lower resolutions. What you get now is a PDF that can be zoomed in and scaled, and all your shape layers will retain their sharp edges. This does mean that shape layers don't get to have filters on them though. Which is a bummer, but we think it's worth the tradeoff. Some blend modes are also not supported. But, we've got this instance covered with the next bullet point. Which is the next line below. Please read on.
New "PDF (Rasterized)" option when exporting, enabled by holding down the option key when clicking on the options popup. This is the old behavior, where a bitmap image is created from your canvas and then stuffed into a PDF.
New Things:
Improved speed with 64 bit images on MacOS 10.14 Mojave!
Now using visual effect views in the palettes, which lets the background color bleed in. However, if you have "Reduct transparency" turned on in the Accessibility System Prefs, then we'll skip the whole background bleeding in thing.
More Stuff:
Improved accuracy with the Curves filter.
More precision when picking out colors on Retina displays with the canvas color loupe.
Various MacOS Mojave UI fixes.
Fixed a problem where web export of images with a layer which has a blend mode of Soft Light gives a preview that doesn't match the canvas.
Fixed a problem where Acorn could quit unexpectedly when cropping an image.
Fixed a problem where you couldn't control-click on a ruler to bring up the units contextual menu.
Fixed a problem when using the Share menu in other applications to send very large images to Acorn.

New in Acorn 6.2.3 (Dec 19, 2018)

New in Acorn 6.2.2 (Oct 12, 2018)

New in Acorn 6.2.1 Build 13201 (Sep 28, 2018)

New in Acorn 6.2 Build 13189 (Sep 25, 2018)

Little New Things:
New Appearance preference when running on Mojave: Pick either Dark Aqua, Aqua, or System to follow the system setting.
The Rotate shape processor now has a cumulative option.
The text palette now has a fill option right above the stroke field. Hurray- no more moving to the shape palette to turn strokes on and off!
Changes:
Improvements to zooming your image in and out with the ⌘-1 through 5 shortcut keys.
Better integration when editing from Photos.app and auto-save.
If no documents are open, and you drag and drop a file into the layers palette, Acorn will now open up that image.
Turned off the behavior where the selected tool is saved as part of the image, rather than global for the app. This means switching between open images will always keep the currently selected tool.
Additional preset scale levels have been added to the Command+ and Command- shortcuts, which helps out on the lower end.
The scale buttons (next to the canvas scale slider) will now stop at a point where the image is zoomed to fit.
Acorn will now show a little warning on the canvas when you copy 100% transparent pixels to the clipboard.
Canvas notifications are now shown at the top of the canvas instead of smack dab in the middle.
Web Export uses fancier scaling, so the edges of circles that butt up against the last column of the image don't get blown out when the image is scaled down.
When auto-save is turned on, non-native images (JPEG, PNG, TIFF, basically everything other than .acorn files) will open up as unsaved new images. This is to keep from re-encoding lossy image formats, and automatically losing data in general. If you enjoyed the previous option, you can turn off auto-save in the General tab of Acorn's preferences window.
The subpixel anti-aliasing option for text boxes has been removed when Acorn is running on MacOS Mojave 10.14 (Apple has removed subpixel anti-aliasing from the system and made it impossible for Acorn to support).
When using Smart Export on single layer via the Export… button, the option to always smart export when saving is now available via the export sheet.
Super minor: The web export window will now default to save your image in the same folder the original image was opened from.
Fixes:
Various MacOS Mojave 10.14 fixes.
Fixed a relatively small drawing problem with ovals.
Fixed a problem where you could make an empty selection on layer masks.
Fixed a problem where the color loupe would sometimes show up when you press the option key over a palette.
Now supporting the new drag and drop stuff from Photos on MacOS 10.14, so we can all enjoy full res images.
Fixed a problem where the Close All menu item was unlocalized.
Zoom to fit refinements for folks who have their scrollbars set to always show.
Fixed a problem where web export wouldn't remember the "Remove metadata" settings between uses.
Fixed a problem when opening certain PDFs and creating an image out of the first page.
Fixed some rounding errors when drawing selections.
Fixed flickering when selecting text.
Fixed a problem where View ▸ Draw Shape Vectors wasn't working correctly with Metal.
Fixed a bug where clicking the mouse with the control key down wouldn't bring up the contextual menu on the canvas.
Fixed a problem where the pencil cursor would go away when drawing.
Fixed a scaling issue with text boxes.

Metal 2 support on macOS High Sierra 10.13 and later:
So what does this get you? Faster panning, brushing, fills, and just a general speed improvement overall. Acorn should feel more fluid, and we've even seen framerates over 160 FPS when brushing on a 2015 iMac 5k.
We've also added some new preferences to choose where the rendering happens, located under the Fussy Stuff tab. You can choose Metal, OpenGL, or Software. You can also choose if the data for your image is stored on the GPU or on the CPU (we realize this is a little ridiculous, and we'll remove these options in a future release, but they are great for playing around with right now).
Other New things:
By very popular demand, color icons are back! They are turned on by default, but if you liked the way things looked previously you can turn off the "Color Interface" option in the General preferences tab.
HEIC/HEIF encoding support for folks running 10.13.4 or later (Save As…, Export…, and Web Export).
Support for opening EPS files.
When taking screenshots the Touch Bar is now included if you're lucky (or unlucky?) enough to have a MacBook Pro.
Support for 30 bit image display for the new iMac Pro.
The Replace Color filter has a new option to ignore alpha when comparing colors.
Changes:
Transforms are a bit faster now by drawing a low-quality transform when moving, and then a high quality one when Acorn has more time to do the rendering.
Added a new pref to turn on or off checking for important news.
Squircles.
Removed some old text styles that no longer made sense, and added some new ones (this is under the Edit ▸ Text Style ▸ sub menu. Did you know you can make your own to save in Acorn's App Support folder?).
The App Store version of Acorn no longer has an option to purchase a 14 day free trial for $0. Various Apple App Store bugs, incomplete APIs, and a general bad experience all around caused us to think hard about removing it and we think it's best to do so for now. A 14 day free trial is still available via our website, where you can download Acorn and try it out right away.
Fixes:
Various little Quality of Life fixes.
Various undo notifications are now 94% more accurate.
Removed some filters which showed up in 10.13 that didn't make sense for Acorn (Hello CILabDeltaE, I'm looking specificaly at you).
Fixed an issue where indexed PNGs were opening up empty.

Text on a path:
Our #1 feature request. It's a big thing, and it's awesome. You can use the Shape ▸ Convert To Path Text menu item when selecting a shape, or you can use the Bezier Text Tool (which is a sub item under the Text Tool button) to click on a path and then start typing.
To go along with this, we've added a new "Graduated Font Scale" shape processor, that increases (or decreases) your fonts on your paths, circles, or even in the old style boxes. Make fancy stuff™.
Clone tool works across layers, images, and more:
Our #2 feature request, and another big thing. The clone tool can now work across layers, images, and can even use group or shape layers as a cloning source. If you'd like to reset the origin where the cloning starts, hold down the shift key when clicking. Using this technique, the clone tool can also function as a stamping tool. Keep the shift key held down if you'd like to clone in a straight line.
Use the option click to define a new clone source, or just begin drawing. Shift click to reset the clone tool's origin.
New Web Export Features:
You can now zoom and pan and use shortcuts to change the scale of your image. There are new options to convert your image to sRGB if it isn't already, and if you are exporting a wide gamut image (such as DP3), there's a new option to highlight he colors that are out of range of sRGB (available on 10.12+ only)!
Web Export also has the option to keep (or remove) image metadata, such as exif properties.
Smart Layer Export Settings Palette:
There's now a configurable palette to setup a layer's Smart Layer Export settings (which were originally introduced way back in Acorn 3.3). You now have a movable frame that represents the export bounds of your image, and you can even give it a real name and everything from there. In addition, you can choose to have your layer automatically export as @1x, @2x, @3x, etc. sizes.
New Bezier tools, stroke alignment, and boolean operations:
You can now set the stroke alignment on shapes to be inner, outer, or center (which has always been the default you're probably used to).
Shapes now have a new boolean operation: Divide, which works on two selected overlapping shapes. In addition to this, when you hold down the option key when using the boolean shape operations, Acorn will keep the original shapes you selected in your layer. ALSO another thing- if you hold down the shift key when using the subtract boolean operation, it'll reverse the order of the shapes, so if you accidentally subtracted things in the wrong order, you can quickly undo and then try again with the shift key.
There are now Shape ▸ Bezier Stuff ▸ Simplify Path and Smooth Path menu items, which do exactly what they say.
There's a new option under the Shape ▸ Bezier Stuff menu item: "Reverse Path". If you drew a path from the right end of your canvas, to the left, and then added text to it, you text will go right to left, and upside down. This might not be what you're after. This new menu item will instead reverse your path, so that it goes the opposite direction. Tada!
When converting text to a bezier shape (via Shape ▸ Bezier Stuff), each glyph in the text box turns into its own path instead of the whole text block being a single path.
One last new thing- when using the pen tool + the shift key to add an anchor to a bezier shape, Acorn will now highlight where the new anchor location will show up.
Load and save color profiles, view wide gamut differences:
Color profiles. Love them or hate them, if you do enough image editing you're going to need to use them at some point. Acorn 6 makes it easier than ever to load and save profiles to your image from the Color Profile sheet. And these days with wide gamut profiles showing up from your iPhone 7, you're going to want to know what pixels are going to change when you convert your painstakingly crafted DP3 image to sRGB for the web. And that's why we've added a new previewing option in Web Export that will show up when you're saving out a wide gamut image.
Make Shape from Selection:
This new menu item, located under the Select menu, will be activated when you've placed selections on the canvas using the various vector options (rect, oval, freehand, etc). It'll also do the correct boolean options if you subtract or add to the selection. This is awesome if you want to add a stroke to your canvas selection.
Good things got better:
Previously modal operations (like Crop, Scale and Rotate, Wrap) are now no longer modal. You can now switch between images without having to finish a crop in your current image.
The Scale and Rotate palette now show the x / y / width / height values of the transforming selection.
New shortcut to crop a single bitmap layer: Command-Shift-Option-K (or you can hold down the Shift key when using the Image ▸ Crop menu item). This works when a crop is on the canvas, or with a selection. If it's a selection, the command is basically a shortcut for invert selection, and then delete.
Instant Alpha gets two new options: the ability to turn on and off the smoothing of the edges, and a contiguous / non contiguous mode.
Other new things:
File ▸ Export ▸ Export All Layers menu, which lets you pick a folder to export all your layers to.
Crop pixel lock & resizing. The crop palette now has an option to lock dimensions. Which you click this, it'll "lock" your crop and the final size of your image will be whatever the pixel dimensions you have set are. For instance, let's say you add a 100x100 size crop on your image, and then press the lock. Then you resize the crop on the canvas to be something larger. When you hit crop, your image will crop to what you've got, and then resize your image down to 100x100. So you can essentially set your image size at the same time you're making a crop.
New "Reflection" filter, which reflects your image as if it was on a shiny table.
New "Linear Gradient Blur" filter, which works just like the radial gradient blur… only without the radial. It's linear (see- it's right in the name that's how you know it's linear).
Softness sliders have been added to the brush, clone, dodge, etc., palettes.
New Automator Action- "Call Filter Preset", which adds a filter preset to images via Automator.
The Filter menu now has a "Presets" sub menu.
New button in the palette to delete layers. You can also drag and drop a layer from the layers list into it for deletion
The shortcut Command-5 will zoom to 50%. And if you're already at 50%, Command-5 will then zoom to 25%. Command-4 will zoom to 800%, and then to 3500% if you're already at 800%. However, the menu items never updated their respective titles to indicate this. In Acorn 6, now they do.
There's now an option in the text palette to invert circle text.
After transforming a selection, Acorn will keep the selection on the canvas (previous versions of Acorn would clear it).
There's a new option in the Crop preset popup "Last Crop". This will place on your canvas the last crop you performed.
Text boxes now have an option for sub-pixel antialiasing in the Quick Config popover. (18294)
The web export window now has a proxy icon for your export data. So instead of saving your image, you can use the proxy icon to drag and drop your image anywhere that can accept the image.
You can now export CMYK TIFF images with depths of 32, 64, and 128 bits per pixel.
The Grayscale filter has a new "Black and white only" option, which works just like the 1bit filter does, but without any extra steps. This also works like a Threshold filter.
You can now use the $filename$ placeholder for the layer in in Smart Layer Export, which will replace it with the name of your document.
The info palette will now show the total pixel count, along with the amount of (uncompressed) memory your image takes up. Double clicking on the move tool (or pressing 'v' twice) will bring it up.
Double clicking or pressing enter on a bezier shape will switch to the the anchor selection tool.
New Superellipse option for boxes when they have a corner radius turned on.
When transforming a shape or selection, there are new options in the palette (and context menu) to flip your image horizontal or vertical.
Filled out the Edit ▸ Tools menu with all the available tools.
In most cases when you try an operation on a locked layer, Acorn would say 'Hey- it's locked. Do you want to unlock?' and if you choose yes it'll unlock and you can try again. In Acorn 6, if you say 'unlock' to that question, Acorn will continue with the previous operation so you won't have to try and do it again.
The meta-data window now shows the pixel dimensions, as well as saved file size of your image.
When cropping, you can hold down the option key + return to crop only the current layer (bitmap layers only).
Added a Boolean Divide option to the Touch Bar for selected shapes.
Added a Contiguous toggle button to the flood fill palette.
If you hold down the option key when selecting a color profile, it'll show you where it was loaded from on disk if available.
If you have a shape layer with processors in it and try and add a new shape, Acorn will no longer warn you that it can't do that. Instead, it'll just add a new shape layer and start adding your new shapes to that.
Notable changes:
Text boxes now clip all text to the box they are set in. This means if your first line of text has a line height that pushes it outside the box it's in, then the text will now be clipped. And if you have a baseline that sends it below the box, then it'll also be clipped. Acorn did text a little sloppy in the past, and drew text outside those boxes- but it caused all kinds of little problems and artifacts to show up. Adding the clip cleans all those cases up. (And what's more- previous versions of Acorn would clip your text in _some_ cases, but not all. Now it's 100% consistent.
When moving a gradient stop, a tooltip is now show with the location of the stop in the gradient.
The shape boolean operations are now powered by Paper.js
The various Export options have been moved under a new File ▸ Export submenu.
When using the Randomize Anchor Location processor on star shapes, the star no longer has a non-closed shape.
The "Change Angle" Shape Processor has been renamed to "Rotate".
The layers list in the canvas contextual menu is now visually listed in the same order as what shows up in the layers palette list.
When moving or resizing a crop, the current x/y/width/height values are shown above the cursor.
Removed the option "Keep crop bounds inside canvas". Snapping to the canvas edges works well enough for this these days.
When switching to the Crop tool and there is a selection, Acorn automatically uses the selection bounds to place a crop on the canvas.
The Image ▸ Trim to Edges command will now crop out any layers who's dimensions fall outside the canvas bounds (even if there aren't any transparent pixels inside the canvas to trim up). (24197)
The Web Export window now tries to be the smallest it can be on Retina displays. (24115)
More accurate CMYK layer export, having to do with alpha blending.
The mirror filter no longer clamps its edges.

New MacBook Pro Touch Bar Things:
Brush tools on bitmap layers: Change the size, opacity, and softness of your brushes.
When no images are open, Acorn will a New button and show a list of recently opened images in Touch Bar, which you can tap to open.
General canvas: Fill & stroke color widgets, share widgets, canvas rotate / flip.
Crop: Rotate left & right, Crop button.
Scale and Transform: Rotate left & right, Apply button.
Free Transform: Flip your layer vertically or horizontally.
Shape Layers: If you have two or more shapes selected, you'll get a boolean operation popover, which lets you then use the union/difference/exclude/intersect operations.
Shape Layers: If you have two or more shapes selected, you'll also get alignment options for those shapes.
Shape Layers: Turn fill and stroke on and off for selected shapes.
Shape Layer Stars: You can adjust the number of points selected stars have using Touch Bar.
Edit in Acorn from Photos:
We've added a new Photos extension, which will let you edit your photo in Acorn (available for macOS 10.11 and 10.12+).
Tabs:
Acorn supports tabs if you are on 10.12 or later. Drag and drop between the layers list and other tabs, it's pretty awesome.
Fixes:
Fixed a problem where histograms were calculating incorrect data for transparent areas.
Fixed a bug where the Text Splitter Processor wasn't working correctly for Circle Text.
Fixed a bug where trying to copy when no layer was currently selected would lead to an error.
Fixed a bug where Acorn couldn't open up some older files where text boxes were set with interesting colors.
Fixed a bug where Acorn could become unstable when bringing up the canvas contextual menu item from a SVG file.
Fixed a problem where opening up iPhone 7 RAW images on macOS Sierra wouldn't show a correct preview in the RAW Import window.
Added a check for the 3rd party filter "SobelEdgeDetectorUnit.plugin", which was crashing Acorn in macOS Sierra.
Fixed a problem where the cursor for the clone tool with the tool tip enabled would draw in the wrong location on retina displays.
Changes:
Acorn no longer requires the discrete graphics card to be in use for MacBook Pros.
The text palette now has an added level of precision for the baseline, kerning, line height, and paragraph spacing fields.
New hidden pref to turn on auto-scrolling for various canvas operations: defaults write com.flyingmeat.Acorn5 autoAutoScroll 1

New Things:
New color picker! Hold down the option key (while in the canvas) when using the brush, pencil, gradient, or fill tools, and you'll get a fancy new loupe to select a color from anywhere on the screen (just click to pick your color). You can also scroll in and out with your scroll wheel (with shift+option down) to change how far in the loupe zooms. And finally if you'd like to get finer control when choosing your color, click and drag the mouse and let up when you've chosen your color. (You can also use the arrow keys to move it by single pixel increments). This is amazing. And if your hands are on the keyboard instead of mouse, you can use the keyboard shortcut Control-C to pick a color out.
Two new dithering filters under Color Adjustment: "1Bit" which will turn your layer in a (seemingly) one bit, black and white image. As well as "Dither", which is a filter which lets you choose from four different types of dithers: Atkinson (old school Mac OS), Floyd Steinberg, Gaussian Blue, and Ordered Reproducible.
Color profile, bit depth, and DPI of an image are now listed in the Metadata window.
New "Spacing" option in the "Arrange Shapes in a Circle" shape processor. A setting of 0 will mean shapes are auto-spaced around the circle evenly. Any other value between 1-360 is the distance (as an angle) between shapes. This means that shapes can either not make it all the way around the circle, or even go around multiple times. Bonus- combine this with the Translate shape process to make shapes do a loop across your canvas.
Layer alignment options: Select multiple layers, and use the various options under Layer ▸ Rotate and Transform ▸ Align to have edges line up or center in canvas, or so on. Hold down the option key for more menu items.
The Layer ▸ Rotate and Transform ▸ Rotate 90° layer menu items now work on a selection.
Changes:
Tightened up some colorspace issues when using the system color loupe from the color panel.
The return of no working pixel processing profile (WPPP for short?) as default. As part of the color profile overhaul, Acorn 5.4 changed the default WPPP to Linear Light and in while this is awesome for doing things with brushes and most other alpha blending scenarios, it probably wasn't the right choice for general webby use and setting colors in general. It also didn't match what most other image editors did as well. So in Acorn 5.5, we're changing it back.
Rolled back the bits from 5.4 where shape layers would draw in a linear RGB colorspace if your document was set to run pixels through a linear colorspace as well.
Removed the View ▸ Select Color menu item, in favor of the Edit ▸ Pick Color menu item. Why didn't anyone notice that we had two different menu items for the same thing till now?
New code for matching your image's color space to the display color space. It's fancy.
Changed the minimum radius of the "Arrange Shapes in a Circle" processor to 0. You can now use this processor to stack all your shapes into a single pile.
The "Monitor Resolution" preset now does the right thing for retina displays.
QOL improvements for the gradient palette: Single click to select and change the color of a color stop. Better drawing and handling of the gradient palette color handles. In addition, if a color handle has the focus of the color palette, it will now draw a little highlight on top of the handle letting you know this.
It is no longer to move layers into or out of locked group layers via the layers list.
Pressing the fx button in the tool palette will now toggle showing the filter sheet if there aren't already filters on the current layer.
Bug fixes:
Fixed some snapping issues when moving selected pixels around the canvas.
Fixed a bug where changing the bounds of a rotated box (or text area) would put it in a funky location.
Tightened up the trim bounds for shape layers.
Fixed an issue where filter descriptions weren't showing up in the filter browser.
Web export will now remember your last "Embed color profile" setting.
Fixed a problem where swapping the front and back colors with the fill tool selected would cause both color wells to get the same color.
Fixed a bug where the 'bitmap layers' AppleScript property was returning more than just bitmap layers.
Fixed a bug where rasterizing a shape layer with selected shapes could cause incorrect drawing.
Fixed a bug where nearest neighbor scaling would clip off an edge of pixels when they were next to a transparent area.
Fixed a problem where text would sometimes smear on the canvas when the text box it was in was too small to contain the text.
Fixed a bug where filters wouldn't be applied to selections if the filter palette wasn't already open.
Fixed a bug where you couldn't use the pencil toll to put a tiny little stamp at 0,0.

New and Changed Stuff:
The Random Noise filter now has a Seed parameter which changes up how the random pixels are generated. They can either always come about in the same order, or you can change things up if you'd like. And things are now 100% consistent between file opens.
New shortcut to open up the Color Profile menu item (Command-Shift-K).
Color Profile: Complete reworking of how Acorn does color management (+ Linear Light RGB is now the default working color profile).
Color Profile Improvement: Shape layers will adjust their drawing depending on what your working color profile is set to now.
Color Profile Improvement: When pasting to an image with a different color space, Acorn will now match (ie, convert) the pixels to the image being pasted into.
New Clamp filter under the Misc section, which is useful if you don't want transparent pixels coming from outside your layer for certain filters (such as the various blurs).
Tweaked the Gaussian Blur filter so that by default it now clamps to the edge of your image, instead of bringing in transparent pixels from outside.
Scripting: The Distributed Objects interface to Acorn via JSTalk or CocoaScript is deprecated (Ie- var acorn = JSTalk.application("Acorn");). You can instead use the technique described under "Writing plugins for Acorn in JSTalk" in the Scripting documentation for automating Acorn, or use the "do JavaScript" AppleScript command.
New scripting API for replacing text in all the text boxes in a document.
AppleScript:
tell application "Acorn"
tell document 1
replace text "$foo$" with "This Is The New String"
end tell
end tell
JavaScript & Cocoascript:
doc.replaceOccurrencesOfString_withString("$foo$", "This Is The New String");
Fixed Stuff:
Better text selection for ranges with line height set to something smaller than the font size.
Fixed a problem where gradients on layer masks with transparency wouldn't blend correctly.
Fixed a problem where Acorn would become unresponsive when opening up bad SVG files.
Dragging and dropping colors on the shape palette mini color wells now correctly sets the right colors for the selected shapes.
Fixed an old old bug with Color Profiles and dealing with various blending issues. If your image has layers with transparency, you might see a slight change in how the blending is performed.
Fixed a crasher which could occur if you were rapidly changing the width or height of a PNG when using Web Export.
Fixed a bug where the clone and smudge tools weren't working for folks.
Fixed a rare and very vexing crasher which would happen sometimes when using a crop preset.
Fixed a bug where setting the height of a bezier path wouldn't work correctly in the inspector.
Fixed a bug where outlining a bezier shape wouldn't always render the correct line join style.
Fixed an issue where your layer could become progressively lighter if the Pixel Processing Profile was set to Generic and your image color profile was set to sRGB.

New and Changed:
Circle Text Tool. This lets you add text to your layer, arranged in a circle. To switch to it, you click and hold on the text tool icon, and you'll get a sub-menu to select the new tool. If you're unhappy with the spacing between the letters- adjust the kerning in the text palette to make it right!.
There's a new menu item under the Shape menu for converting between circle and boxed text.
The minimum and maximum values for the kerning, baseline, paragraph spacing, and line height sliders are now based off the font size of the selected text box. This means you'll get saner values for really small or really big font sizes.
When editing a text box, pressing the Command-Enter keys will end your editing session.
You can now adjust the kerning for a selected text box by using the Command-Option-(Left|Right) arrow keys.
You can now drag and drop images from Photos onto Acorn's canvas to add additional layers to an open image.
The Layer ▸ Color Controls window is now been moved to the stackable filters. This gets rid of a modal window, allows for changing values later on, and even works on shape and group layers now.
The Expand Canvas to Fit Layers command now does a better job at figuring out bounds when you have layer filters involved.
Brush Designer: When changing brush sliders, Acorn will now update the brush preview in realime (60fps) to let you know what's going on in the background instead of waiting for the drawing to occur and then redrawing everything at once.
Exposure, Color Controls, and Remove Color Cast filters now have their values move in sane increments when using the up/down arrow keys in their respective text fields.
Shapes which have a radius setting (such as the star shape and circle text) can now have that value changed in the Shape Palette inspector while it's selected. You can also change the x and y coordinates of its center from that palette as well.
Fixed:
Fixed an issue where croping an image with layer filters would move them incorrectly.
Moving a bitmap selection will now snap to guides and such.
Fixed a rare crasher when updating brush settings in the brush designer and then drawing on the canvas again right away.
Fixed an issue where shape layers wouldn't update right away when resizing the canvas.
Fixed an issue where creating a 16bpc image from a RAW file wasn't working correctly on 10.10
Fixed an issue where the Apply Layer Mask command wouldn't work if you had the layer mask active (via the layers list).
Fixed an issue with Smart Layer Export where some images would get banding on the right side of the image on 10.11.
Fixed an issue where you couldn't change the kerning for selected text sometimes.
Fixed an issue where the polygon selection tool would sometimes leave artifacts on the canvas.
Fixed a couple of cases where you could end up with empty selections.
Various other minor fixes.

New:
Deep color image support. Do you have a 5k iMac or recent Mac Pro with a 30 bit display? Then you get to enjoy a new level of color accuracy using Acorn 5.2. Make a 16bpc image, and you'll no longer have crazy gradient banding! Deeper colors, and a wider gamut. What's not to like about that?!
New color well in the tools palette. It's a bit more clear which color is for stroke and which one is for fill when dealing with shapes.
Acorn can now open up basic SVG files. The File ▸ New Document from Clipboard menu item will now also with with SVG data on the clipboard.
If you have multiple fonts selected for a text box, a little note will show up next to the font family popup letting know this.
You can now paste your selection when in quickmask mode.
Changed the default colors from a white fill and black stroke, to a white stroke and black fill. This makes adding text for the first time much more sane.
The previously blank palette (when you click on the move tool) is now populated with various statistics about the open document.
If you're on 10.11 or later, Acorn can now export your image as TGA.
Fixed:
Fixed a bug where the Crop Automator Action wouldn't work correctly when used as a Finder service.
Fixed a bug where Acorn would show hidden layers on SVG export.
Fixed a bug where Google's Raleway font couldn't be selected.
Fixed a bug where pressing the bold button in the text palette wouldn't always unbold bolded text.
Acorn does a better job at remembering the extension you were using for your file when doing a Save As (think jpeg vs. jpg).
Fixed a problem where the colorspace for images made from the clipboard was lost when you copied from Sketch.
Fixed a problem where you couldn't import Photoshop brushes if you didn't already have Photoshop installed.
Fixed a bug where you would sometimes start rotating a shape when you meant to resize it.
Fixed some redraw problems with selections when you were zoomed in.
It's a bit easier to select text boxes when you're on a shape layer (ie- click throughs don't happen when you click between letters).
Various other bug fixes we're too lazy or embarrassed to talk about.

The Shape Processor:
Acorn has a really great new feature called "Shape Processing". Have you ever wanted to generate a bunch of new shapes, and then arrange them all in a circle and adjust that radius right on the canvas? What about taking all your shapes and re-ordering them from smallest to largest? What if you wanted to take all your shapes and randomly assign each one a new color, and then scatter them around the canvas in a billion different locations? What about pushing all the shapes on your layer out of the way of a giant circle? Well, now you can.
Shape Processors are filters for shape layers, which will move and tweak and generate and adjust shapes for you. And best of all, they are non-destructive and stackable (just like Acorn's filters). So you can add a bunch, tweak, save, close, and come back later if you change your mind.
Things that go snap:
This is a lot more snapping going on now. Snap to Grid, guides, shapes in layers, other layers, selections, canvas bounds, etc. It was a complete rewrite, there are now global preferences available for fine tuning how you'd like it to work, and we even made those changeable per document.
Completely rewritten bitmap selection stuff:
It's super accurate and works wonders with retina displays.
Non destructive Levels and Curves:
Levels and Curves joins all the other non destructive filters- this is pretty awesome. You can use Levels and Curves on shape layers, even combine in the same filters list, tweaking both at the same time, and add a Curves filter multiple times to the same image. I have no idea why you'd do this, but it sounds fun.
PDF Import:
When you open up a PDF, you can now choose the resolution, page, and background color of the PDF you are opening.
Crop tool improvements:
Pressing 'x' will now swap the aspect ratio of the current crop frame (if you have one that is, otherwise it'll swap the current back and foreground colors).
Pressing 'h' will toggle hiding the areas outside of your crop frame.
You can now rotate your image while making a crop.
Hundreds of minor bug fixes:
Yes, we are really going to list this in the "big new things" section.
We fixed hundreds of minor bugs. Bugs that built up over the years that very few people ever encountered, like "the shortcut key for zooming in doesn't work when the keyboard layout is set to Dvorak - Qwerty ⌘". So we fixed pretty much all of those. It took months and months of work, it was super boring and mind numbing and it was really hard to justify, and it made Acorn 5 super late. But we did it anyway, because something in us felt that software quality has been going downhill in general, and we sure as heck weren't going to let that happen to Acorn. So we took a long break from adding features and just fixed stuff.
And if you reported one of these bugs that was fixed in Acorn 5 and we haven't already sent you a license- let us know and we'll make you one. (See, another good reason to report any bugs you find- free stuff!).
More shape layer and bezier stuff:
New menu items - "Shape ▸ Bezier Stuff ▸ Align Anchors to Pixels" and "Align Anchors to Half Pixels" (the latter command shows up when you hold down the option key). This will align all the anchor points in your shape to the pixel grid (or half of it). This helps with making crisp lines for you bezier nuts out there.
You can now change the inner radius of star shapes. THIS IS AWESOME. It's actually quite flexible, and you can make some really neat star shapes (and did you know- you can change the number of points on your star using the View ▸ Quick Config popover?).
New option to reset bezier control points under the Shape ▸ Bezier Stuff menu
If you double click on an open bezier shape, it will signal to the shape that you would like to continue extending it. There's also the option to do this under the Shape ▸ Bezier Stuff menu item.
You can temporarily toggle the "snap to pixels" setting when moving a bezier anchor by holding down the control key while moving it with the mouse.
You can now invert the selection on shape layers.
The Shape Quick Config popover will now work when you don't have any shapes selected (and the settings you change will reflect on the next shape you make).
The contextual menu for the layers list has a new "Rasterize Shape Layer" menu for use on shape layers.
You can now close a path when creating it by pressing the enter or return keys. Pressing the escape key will finish editing it as well, but keep it open.
You can now move multiple selected anchors in a bezier path with the arrow keys or mouse.
If you have the option "auto select layers" turned off, a single click and drag in a shape layer will now move all the graphics without them needing to be selected first.
If you have a single text box selected and you press the enter key, Acorn will start editing it.
Holding the command key over a control point for resizing shapes will allow you to rotate it instead. I'm thinking of killing off the secret rotate handles outside shapes as well. Does anyone care?
Added Control-C as a way to select a color. This is awesome if you want to pick up on another color, but you're currently editing text and the 'i' key doesn't cut it.
Changed the modifier to move selected shapes by a half pixel to shift-option (from command-option).
New shortcuts to toggle the fill / stroke on selected shapes. Shift-F for fill, Shift-B for stroke.
New blend modes:
Acorn now has a "Pin Light" blend mode, as well as a "Mask" blend mode. The Mask one is pretty awesome- it works just like a layer mask, white lets pixels through, black erases.
Support for Photoshop brushes:
There's approximately 10 billion PS brushes available for download on the internet, and you can drag and drop one onto Acorn to import and make new brushes.
Speaking of brushes:
The Brush tool has now been renamed to the Paint tool. Because a bunch of other tools now use brushes, and it hopefully reduces confusion.
About those other changes I just mentioned. The clone, paint, smudge, dodge, burn, and other tools that had crappy brushes now each have their own unique brush that you can configure via the brush designer. So now you can have scatter for the clone tool. Or adjust flow and softness for the burn tool. Or turn pressure sensitivity on and off for the eraser. Etc.
Image metadata editing (aka, EXIF and IPTC, sitting in a tree):
Image metadata is now viewable and editable. Use the File ▸ File Info… menu item to bring up the editor. While not everything is editable, lots of good things are. And this is new- so if there's something you'd like to see here, let us know!
New options in the Filter Palette having to do with selections:
"Blend with canvas selection", which is the old standard behavior when applying filters to the selection. Acorn will apply your filter(s) to the currently selected area in your bitmap, and then draw the results of that filter over your layer.
"Copy over canvas selection". This option will apply your filters to the current selection, and then replace the pixels in your selected area with the results of the filter. So in this case, if the filter returns transparent pixels, your layer will become transparent in those areas.
"Ignore canvas selection". This option will ignore the canvas selection, and work copy the result on top of your whole layer.
Miscellaneous new stuff:
When using Web Export, there's a new option to save your image with or without a color profile. It defaults to yes.
Pressing 'b' while in crop mode will toggle the "Keep crop bounds inside canvas" option.
When using the search field in the filter browser, searches will also look in the description for the filter as well as the name. This way searching for "saturation" will return Color Controls and Vibrance, where before it would return nothing.
New filter! "Redraw Layer". Here's how it works- add a blur filter, then add a monotone filter, then add the redraw layer. INSTANT DROP SHADOW THING. It's great if you want to apply some filters and then have your original image draw on top of everything.
ANOTHER NEW FILTER! "Offset". This will … offset your image. COMBINE THIS WITH REDRAW LAYER. Add a monotone, add an offset, add the redraw, and tada- you've got instant solid color copy of your image, but in the background. Great for doing simple emboss operations.
WHAT'S THIS? YET ANOTHER NEW FILTER?!?! Yes, it's true. There's now "Remove Color Cast" under the Color Adjustments, which will help you remove things like the pesky yellow tint that you'll get from lightbulbs when shooting photos indoors.
Holding down the option in the stroke / fill / etc text fields when using the up and down arrows will change the value by .1. (Holding shift will change the value by 10 btw).
You can now click the zoom scale field in the bottom window, and change the canvas zoom by typing in a new value. Holding down the command key while clicking it will scale the canvas to 100%
Pressing shift-x will swap which color well has the focus for receiving color changes (and did you know pressing x will swap the fill and stroke colors?).
If you have one or more anchors selected in a bezier path, the Shape ▸ Bezier Stuff ▸ Align Selected Anchors to Pixel menu item will appear. Hold down option to align to half pixel. This menu item is "Align all Anchors to (Half) Pixels" normally.
All of Acorn's documentation and tutorials are now indexed for searching via the Help menu. Try it out, it's pretty awesome.
New undo / redo notifications in the canvas. You can turn this on and off in the preferences. For the beta this is turned on by default (shipping won't however). I'd like a little feedback on it if you have any, which is why I'm forcing it on everyone to start with.
128 Bits Per Component support. Super deep images. Because why not?
If you add a single image via the File ▸ Add Images… menu item, and it doesn't fit on the canvas, Acorn will begin a scale and rotate transform for you, with the image automatically scaled to fit into the canvas. If you want to pop out of the scale, pressing the ESC key will end it.
Guides will now scale with image when resizing.
The Selection palette will now show the x,y coordinates of the current selection now. It'll also hide the labels and such when there is no selection.
You can now delete a brush by selecting it from the brush palette list, and holding down the option key.
You can now command click on a layer mask's thumbnail to make a selection out of that mask.
When opening multipage tiff files, Acorn will now expand the canvas size to the largest page in the tiff file.
New filter "Alpha Multiply", which will multiple the alpha values of your pixels by a certain amount, which can be awesome when you want to sharpen up anti-aliased edges of circles and other shapes.
You can now commit a bitmap layer mask by holding down the option key and choosing the Layer ▸ Apply Layer Mask menu item.
The Clone, Smudge, Dodge, and Burn tools all have opacity options now.
If you hold down the shift key when creating a new guide from the ruler, Acorn will now create a vertical ruler where it would have previously created a horizontal ruler (and vice versa).
You can now drag and drop gradients from the gradient preview onto a shape or bitmap layer to apply it.
Hidden feature: Pressing 'x' when the gradient tool is active will flip the gradient colors.
There's a new option in the Canvas Size sheet which allows you to move the canvas guides (or not) when resizing.
The Bevel filter now has a Scale option, which can add a bit of finesse to your bevel.
Changed Stuff:
We killed the little swap width and height widget in the new document window. Instead, you can use the keyboard shortcut cmd-] or cmd-[ to have them swap (and the menu items Image ▸ Rotate Canvas ▸ 90° Clockwise / Counter-Clockwise also does the same thing).
Zooming with a trackpad is a bit more consistent.
Removed the quickmask and fullscreen buttons from the tools palette. The full screen became silly on 10.9 w/ every window getting that button too, and the quick mask seems out of place by itself there.
Hiding the cursor when you do a two finger scroll. There's a system bug (feature?) where the cursor will constantly flicker otherwise. It's annoying, so we'll be hiding the cursor till a real fix comes from Apple or I find a better workaround.
Got rid of the brushes in the Erase category of brushes, since the eraser tool now uses the same system and it was kind of pointless. ALSO- did you know you can convert a brush to an eraser at just by holding down the command and option keys and then drawing with it?
When using the system eyedropper to pick up a color on the canvas, it now takes the composite of the layers, instead of the first color on the top layer. If you want to pick up on a specific color (including alpha) from a single layer, use a drawing tool such as the paint tool, and hold down the option key to pick up the color.
If you press a keyboard shortcut while editing a field that takes a numerical value (for instance, the brush size field), Acorn will ignore the letter you typed, and instead choose the tool. Is this annoying? Is this odd? I don't know yet, but I'm going to try it for a bit.
When switching to the crop tool with the 'c' key, Acorn will no longer automatically put a crop on the canvas for you. However, if you liked the old behavior, you can press the 'c' key twice in less than half a second, and you'll get an auto-crop on the canvas.
New fussy pref to change the opacity of the crop tool mask when making a crop.
The way brushing works has been rewritten considerably. Colors are much more accurate now.
Generate Shapes has been moved to the Shape ▸ Process menu.
Very very very slight (super tiny) change to the way star shapes are drawn. It's a bit more accurate now, because Gus learnt a thing or two about maths.
The Line tool (shortcut key ';') is now a specialized bezier path. We're thinking of removing it actually…
If you have the preference to listen for trackpad rotation gestures turned on, it takes a little bit more effort to pop into rotating your canvas (which is a good thing).
The gather palettes command does a much better job at resizing the windows when the display resolution changes to something smaller (or you move your palettes to a shorter window).
The gradient swatches now do a better job drawing when you've got the system scrollbar pref set to always show the scroller.
Layer styles now respect the canvas origin preferences.
Acorn will no longer ask to move itself to the Applications folder if there's a newer version already there.
Double clicking a thumbnail in the layers list palette will make a selection out of that layer.
The target click area for the fx widget in the layers list is now from top to bottom of the cell, instead of the little 'fx' bit. Sloppy pointer skills rejoice.
The Edit ▸ Fill… command is a bit more precise when it comes to opacity percentages.
If there's a network error when trying to use the feedback window, Acorn will offer to send the report via your email client.
You can no longer insert new layers into locked groups.
You can no longer draw or alter a layer that's inside a locked group.
When taking a screenshot, each display now gets it own document.
The feedback window will now save its contents when you quit, and restore everything when you next launch.
When opening up ICNS and WebP images, Acorn will now place them into a new untitled document, instead of referencing the original file. Acorn doesn't save these file types natively, so referencing the original image causes confusion with various parts of Acorn.
No longer loading Python plugins. If you really miss them, and would like to bring them back while you transition away from them, paste the following line in Terminal.app:
defaults write com.flyingmeat.Acorn5 loadPythonPlugins 1
No longer loading Quartz Composition filters. If you really miss them, and would like to bring them back while you transition away from them, paste the following line in Terminal.app:
defaults write com.flyingmeat.Acorn5 loadQCCompositions 1
Now showing a warning when you try and scale up an image to a very large size in Web Export.
Acorn does a better job at generating previews for filters which take textures (like Glass Distortion)
Copying a layer to the clipboard will now set the correct opacity if you have the layer's opacity set to something less than 100%.
Acorn does a better job at figuring out the bounds of your image when trimming.
The kerning slider now goes from -500 to +500.
Web Export now remembers the matte color option between uses.
Acorn does a better job of matching up the brush cursor size with the canvas when you have the cursor size embiggened in the Accessibility System Preferences.
When exporting an image, Acorn no longer warns you if your image is being saved without layers. It's an export, yea- you're original file is fine.
The tool palettes hide automatically when opening up a RAW image, since they pretty much only get in the way.
Pressing 'm' will no longer cycle through the selection tools, and will now only select the rectangle selection tool. However, shift-m will cycle through the selection tools as in previous versions of Acorn.
When applying gradients to selected shapes, Acorn will now hide the selection bounds. This is handy because it helps you see exactly what you're going to get.
Updated some of the built in brushes, and removed old crusty ones.
When drawing on a mask, Acorn now converts the current color to a shade between black and white (otherwise the mask would get splotches of color on it, which doesn't make too much sense for a mask).
Guides are now 2 pixels wide, because this makes more sense when you want a shape to line up with it on it's center, not it's edge (which will change depending on which direction you are aligning something from).
Smaller PNG files on web export if there's no alpha channel needed.
Acorn does a better job with selection edges and the free transform tool.
Changed up the wording for the pixel processing options. None, Generic, and Linear Light are the new options. Killed document. That's fine, nobody but Gus and the Core Image team actually understands what this is.
Other Stuff:
New Scripting interface for bitmap layers.

New:
New international presets when creating a new image - A3, A4, A5, and A6.
New Command: Layer ▸ Merge Visible to New Layer (shortcut Command-Option-Shift-E). This will add a new layer, which is a composite of all the visible layers. The menu item for Merge Visible will switch to Merge Visible to New Layer when the Option key is pressed.
You can now paste an image into the brush designer's canvas, which will then take that image and turn it into a brush.
New Crop preset: "Document". It adds a crop to the canvas at 90% of the canvas size, and will keep its aspect ratio when resizing.
New AppleScript command: "add layer mask". Works on either the document or layer object, and if there's a selection on the canvas, that will be used as the mask (otherwise the command will add an empty layer mask). There is also a new Cocoa Script interface to it for the layer object- addMask:.
When browsing for a new filter in the filters list, changing the front and back colors in the tool palette will now update the colors in the current preview filter.
The Raw Image Import window now supports full screen editing.
The gradient tool now has an optional blend mode when used on bitmap layers.
Acorn will automatically hide palettes when Web Export is used.
If you paste in dimensions such as "1256x408" into the width field of the new image window, Acorn will recognize that you probably want an image with a height of 408, and will automatically set that value for you.
The eraser tool now has a precision mode option just like the brush tools do (this will slow down your strokes by 3x, making it easier to add small brush strokes).
You can now click and drag with the flood fill tool to increase its base tolerance setting, just like with the magic wand and instant alpha tools.
The tolerance setting for the magic wand will live update when you click and drag on the canvas - which will increase it by the base amount you have set.
You can now reset individual values in a layer filter by double clicking on its label.
New shortcut (command-option-shift-n) to create a shape layer.
Spotlight indexing now includes the fonts in the image as well as the pixel count.
Pressing the + in the Inspector Palette with the Option and Command keys down will add a new Shape layer (and holding down just the Command key will create a new Group layer, and holding down the option key will duplicate the current layer).
You can now lock / unlock layers with the command-option-l shortcut.
Acorn can now open up .pict files. Yes, really. Hello, 1984 called and wants its file format back.
Changed:
If you have a bitmap layer which is completely transparent, the various transform tools will now let you know that they have no job to do. And if that empty layer has layer filters which generate pixels (such as Render Clouds), Acorn will ask if you want to flatten the filters before continuing.
The Shape Generator sheet (under Shape ▸ Generate Shapes) will now remember previous settings.
Acorn no longer lets you set the paragraph spacing of text objects to a negative value. This sometimes worked, even though Acorn was using APIs incorrectly to make it happen- you would get unpredictable results depending on the selected font, and the values were sometimes reset when you reopened a file.
If the currently selected layer is invisible, the blend mode, opacity slider, and any layer filters it has will now be disabled in the filter palette until the layer is made visible again.
When using Crop presets that are too big for the canvas, Acorn will now do a better job of scaling things down for you.
When adding a layer filter preset, Acorn will no longer replace any existing layer filters and instead append to the filters that are already present. If you like the previous behavior, you can hold down the shift key while choosing the preset to replace the current filter(s).
Web Export: If you have the matte option enabled and are exporting as PNG, Acorn will no longer add a (useless) alpha channel to the image, which will make the file size a bit smaller.
Deleting the contents of a bitmap layer is way faster now if you've got a huge canvas and just a teeny tiny bit of visible pixels on the layer. Yes, we try and rub the speed on everywhere possible.
When manipulating star shapes, it will always grow / shrink on either size instead of just one.
Acorn is taking advantage of more caches to speed up compositing, which helps enormously with layer styles.
Brought the way background shape layers are selected to be more inline with what happens when selecting bitmap layers. Acorn no longer gives precedence to the currently selected shape layer when clicking on shapes which might be overlapped by other shape layers. If you were enamored with the previous behavior, you can bring it back with this hidden pref: defaults write com.flyingmeat.Acorn4 checkSelectedShapeLayerFirst 1
Smoother selection animations, as well as rotating colors for the selection (does it stand out more on retina displays now?)
Less beeping.
When you have multiple groups selected in the layers list, Acorn will now stuff them into a single group when the New Group command is used. This now matches the same behavior when multiple non-group layers are selected. Previously Acorn would add a new group layer to the selected group (and Acorn will still do this if there is a single group selected).
Acorn now remembers which color well was selected when you quit and restart.
New hidden pref for automatically adding a white background when opening a PDF: defaults write com.flyingmeat.Acorn4 whitePDFBackground 1
Fixed:
Fixed a bug where removing an anchor in the Curves window wouldn't update the preview.
Fixed a bug where you couldn't properly use the Outline Path command on Line shapes.
Fixed a crasher when deleting every selected segment of a bezier path.
Fixed a bug where Web Export wasn't working when in trial mode.
Fixed a bug where sometimes dragging and dropping an image from the Canvas into the Brush Designer image well (to make a brush shape from the image) wouldn't always work.
Making selections with the free and polygon selection tools is a bit more natural feeling when zoomed way in.
Making single pixel selections with the rectangle selection tool is a lot easier to do when zoomed way in (you don't have to drag your cursor around as much).
Fixed a bug where precision mode with the brush and eraser didn't work great when you were zoomed in our out a bunch.
The Magic Wand cursor was missing + and - symbols when you held down the shift and option keys to add or subtract to a selection. This has been corrected.
Fixed a bug where masks in PSD files wouldn't open up correctly with certain images.
When in Quickmask mode, adding layer filters to the selection works better now.
The reset button in the filters palette now matches what you get when you add the filter to your layer.
The tab key now works correctly to move between fields in the Levels window.
The text insertion point no longer gets layer effects applied to it when you are editing text.
New document from clipboard now works better when you've got a bunch of shapes copied from a shape layer.
Fixed a bug where the ungroup layers command wouldn't work correctly for selections of multiple layers.
When creating shapes, they now snap to rulers and document bounds.
Fixed a problem where the clone tool didn't give the greatest results when cloning from transparent areas in a layer.
The File ▸ Add Images… sheet no longer allows you to select images Acorn can't open (such as EPS files).
Better drawing of text bounds when you're zoomed in and modifying stuff.

New:
Live font updates to text boxes as you move look through the font list in the text palette.
Acorn will now give live updates to the blending mode for layers when using the arrow keys on the Blending popup button.
New preference for a "Super Scrollable Canvas", which basically means you can scroll your canvas around beyond the bounds of your image. This is awesome if you do lots of work with a stylus.
When making or moving guides, they will now snap to document bounds (if you have the snap options turned on. And did you know you can temporarily disable snapping by holding down the control key? Well, now you do).
When dropping into Quickmask mode, Acorn will set the front color to white and the back color to black, making it easier to draw in or erase your selection. When you drop out of Quickmask mode, your previous colors are restored.
If you have multiple layers selected and want to put them in a group, command-g is your friend. And if you have a group layer selected and would like to ungroup it - command-shift-g is also your friend.
New Clear Selection and Inverse Selection menu items added to the canvas contextual menu when you have a selection.
If you double click on the Text Palette's baseline, kerning, line height, or paragraph spacing labels, Acorn will reset the value of that slider. If you hold down the command key while double clicking on any of those, Acorn will reset all the text spacing values.
You can now select non-contiguous layers in the layers list, and merge them into a single layer using the Layer ▸ Merge Layers menu item.
The contextual menu in the layers list now allows you to merge a clicked layer down.
Pressing cmd-1 would always scale your canvas to 100%. But new in 4.4: if your canvas is already at 100% and you press cmd-1, the canvas will center itself.
You can now export an image as a TIFF with CMKY.
When you change values in the brush designer, updates to your brush strokes are done in the background. This is awesome because it means Acorn stays super responsive when you're making little changes.
Changed:
You can now have a negative baseline for text shapes.
Acorn now defaults to keeping objects selected after creating them (though you can change this in the prefs if you liked the old behavior).
First, some background: Selections are undable. Shape layers can have selections of their own. Shape layer selections are removed when you switch to another layer. If you are on a shape layer with a selection and move to another layer, your selection would be removed and if you hit undo your selection would come back. However, the active layer was still the one you moved to. So now in version 4.4, if you undo a selection on a shape layer and it's not the active layer, Acorn will now make it active. So an undo (or redo) action could potentionally change the active layer. I hope that made sense.
There was a menu shortcut conflict introducted at some point, where Hide Selection and Hide Layer were both given control-command-h. The shortcut for Hide Layer has been remapped to shift-control-command-h to resolve this.
If you delete a layer, and then undo it- Acorn will now remember to reselect it if the layer was selected before deletion.
You can now delete a layer while transforming it, without an alert coming up.
Crop preset improvements: If you have the option "Keep aspect ratio" enabled when saving a crop preset, and the size of that preset is smaller than the canvas you are using it against, Acorn will scale up the preset to the size of the canvas while preserving the aspect ratio.
The Automator actions got a little love - please let us know ASAP if something stoped working for you.
QuickLook previews of Acorn images should be loading faster now. In addition, Acorn now saves thumbnails for native Acorn images, so QuickLook thumbnails now show up super fast for really big images.
When copying to the clipboard, Acorn will now make sure the dpi for your image tags along as well.
If a shape layer has a linked mask, and you are moving every shape on the layer, then the mask will move as well. If you don't have all the shapes selected, the layer mask will not move.
Fixed Stuff
Fixed a bug where Acorn wouldn't open rotated + flipped (as set in the exif orientation information) images correctly.
Fixed a bug where web export would show text selection if you had… text selected in your canvas.
Fixed a bug where you couldn't delete a layer with command-delete if it wasn't visible.
Fixed a bug where option-dragging bitmap layers on the canvas to duplicate them would make them show up in strange places sometimes.
Fixed a bug where PSD files weren't exported correctly for small layers.
Fixed a bug where setting the opacity for a layer would sometimes fail if you had just deleted a layer's mask.
Fixed a bug where switching to a layer mask from a shape layer woulnd't clear the layer selection.
Fixed a bug where the [ and ] keys wouldn't change the pencil tool brush size.
Better stylus (Wacom and friends) handling when brushing.
Fixed a bug with the brush tool where sometimes the first dab with a tablet would show up 100% opaque when it wasn't supposed to.
Fixed some visual glitches with the Magic Wand HUD.
Fixed a bug where the ruler bounds markers when moving around a vector shape were drawing in the wrong location on retina displays.
Fixed a problem where moving your layer around while in Free Rotate would cause it to move at half the speed it should on retina displays.
Fixed a bug where rotated + squished brushes would sometimes clip when drawing.

New Stuff:
New preference for a "Super Scrollable Canvas", which basically means you can scroll your canvas around beyond the bounds of your image. This is awesome if you do lots of work with a stylus.
You can now export an image as a TIFF with CMKY.
When you change values in the brush designer, updates to your brush strokes are done in the background. This is awesome because it means Acorn stays super responsive when you're making little changes.
AppleScript stuff to make better documentation with layer
Changed Stuff:
The Automator actions got a little love - please let us know ASAP if something stoped working for you.
QuickLook previews of Acorn images should be loading faster now. In addition, Acorn now saves thumbnails for native Acorn images, so QuickLook thumbnails now show up super fast for really big images.
When copying to the clipboard, Acorn will now make sure the dpi for your image tags along as well.
If a shape layer has a linked mask, and you are moving every shape on the layer, then the mask will move as well. If you don't have all the shapes selected, the layer mask will not move.
Fixed Stuff
Fixed a bug where rotated + squished brushes would sometimes clip when drawing.
Various canvas free rotate bug fixes.

New in Acorn 4.3.1 Build 8502 (Feb 25, 2014)

New Stuff:
New menu item in the View ▸ Guides menu to turn on and off snapping to guides.
If you have a selection, the frame of the selection will now show up in the status bar of your image's window. This is awesome because sometimes it's hard to know if you have a 1x1 pixel selection or not.
New option to set the image depth when making a new image.
The Curves window now has a preview toggle button.
Crop Presets: There is a new option to resize your image to the original crop dimensions when saving a crop preset.
Raw Import: The raw import window now includes a histogram for your viewing pleasure.
Raw Import: You can now choose the color profile you want your image to end up in.
Raw Import: You can now choose the image depth you want your image to end up in.
Raw Import: You can now more accurately change the width and height of the image that is being opened.
Raw Import: New option to adjust noise reduction.
Raw Import: It's faster!
Changed Stuff:
Web Export more aggressively tries to get your PNGs smaller if your colorspace is sRGB (Acorn will strip out the color profile data in that case).
BMP files without an embedded colorspace would previously open up in Adobe RGB 1998. In Acorn 4.3, they will now open in whatever your default colorspace is set to (which is sRGB by default). This also matches system behavior.
Text boxes will now draw an outline when you are rotating or moving them around. This is awesome because it makes it way easier to align stuff up.
Little pencil and brush improvements with single clicks.
If it takes more than .2 seconds to render your brush stroke in the Brush Designer, Acorn will cancel the realtime updates for it and wait till you've finished moving your slider around to re-render your stroke with the updated settings.
When uploading an image to Facebook / Flickr / Wherevr, Acorn will now make sure the exif info for the image tags along.
Undo should be faster now for Very Large Images.
If you drag the top colorwell (stroke color) onto a shape, it will now turn on the shape's stroke if it isn't already, and set the stroke color. Likewise, the lower colorwell (fill) will turn on the fill for a shape as well as set it's color.
The title of the crop preset pulldown will change to the title of the of a selected preset when used.
The layers list thumbnail drawing has been sped up by a factor of a billion and four.
The max grid spacing has been bumped up to 500px.
Fixed Stuff:
Fixed a bug where single clicking outside a selection with the selection tool wouldn't clear the selection.
Fixed a problem where you'd sometimes get transparent edges by using the nearest neighbor scaling option when resizing an image.
Better handling of mouse position when using the brush tool's precision mode on secondary displays or retina screens.
Fixed a bug where Flood Fill wasn't working correctly in quick mask mode.
Fixed some selection redraw problems when your canvas was scaled up to oddball percentages.
Shadows on shapes now scale correctly when scaling down a bezier shape.
The gradient palette preview now updates when you undo a gradient change on a selected shape, instead of retaining the previous gradient.
Fixed a bug where the title of New View windows weren't updated when you saved a document with a new name.
Fixed a bug where you couldn't use the arrow keys when using the perspective transform to move your image.
Fixed a redraw problem with the rulers when panning with a trackpad in full screen mode.
Fixed some cases where you could alter shapes on a locked layer.
Fixed a pixel grid redraw problem when resizing the canvas.
Creating a new rect or oval with the option key down will now make it grow in size from the center of the shape (previously you had to press the option key before clicking).
Fixed an issue where switching from the poly selection tool (without closing a selection you've started) to another tool would cause ferrets to drop from the ceiling.
Fixed a crasher when using Select All with the crop tool when there was a selection on the canvas already.
Better shape selection behavior when you've got one of the shape tools selected and you hold down the command key when clicking on a shape to extend your selection.
Fixed a bug where Acorn would sometimes lose the currently selected layer when re-ordering layers in the layers list..
Fixed a bug where dragging and dropping a monochrome image from Safari onto Acorn's icon in the Dock would cause the world to implode.
Fixed a bug where double clicking on the bezier tool in the tools palette to show it's tool menu, and then quickly double clicking on another tool would cause the bezier tool menu to show up again.
Fixed a bug where text boxes would look funny when editing them and resizing your image at the same time with the option-command window resize widget trick.
Fixed a bug with PSD export.
Fixed a bug where next text boxes wouldn't respect certain text palette settings.
Fixed a bug where you couldn't convert the first anchor point in a bezier path if it wasn't already a curve.
Fixed a bug when drawing gradients in the quick mask.
Various little Tilt Shift filter fixes.
Acorn does a better job of remembering the layers you had selected when you have multiple images open and frequently switch between them.
The order in which multiple images are dragged from the Finder into the canvas or layers list is now the same (it was backwards in the layers list).
Fixed a bug where swapping colors in the palette when you had a range of text selected (in a text box) wouldn't change only the selected text.
Various little fixes with Quartz Composer plugins.
Fixed a bug where moving selected shapes with the keyboard wouldn't update its position in the inspector palette.
Fixed a bug where dragging an image from the Finder would sometimes cause it to show up in the wrong location.
Fixed a bug where resizing the canvas in centimeters didn't work correctly.
Fixed a bug where pressing the escape key when making a selection with the polygon select tool wouldn't clear out the canvas.
Fixed a problem when writing out PSD files with interesting layer names.
Fixed some problems when drawing bezier paths.
Fixed a bug where CMKY JPEG broke on 10.9.1
Fixed a bug where Acorn wouldn't ask if you wanted to finish your rotate or transform if you saved your document while in the thick of it.
Fixed a bug where merging layer groups would sometimes fail to happen with specific layer filters enabled.
Fixed a bug where swapping the fill and stroke colors on a text box would cause it's text to become selected.
Other misc. minor fixes.
Other Stuff:
A new hidden pref to enable (or disable) brute force compressing when using PNGs in Web Export. Enabling this will take longer for Acorn to produce your file, but the size might well be smaller.
A new hidden pref to enable (or disable) preliminary LIFT image support (use File ▸ Export to save your image as a LIFT image).

Changed Stuff:
The magic wand is a bit smarter about selecting transparent pixels.
If an image has no detectiable color profile embeded in it, Acorn will now default to whatever you have set in your preferences for a default color space (by default it's sRGB). Previously it would use the display colorspace on 10.8, and sRGB on 10.9.
The raw import window now remembers its size between uses.
Added some better defaults for the tilt shift filter.
When making a new image from the clipboard, Acorn will now set the DPI based on what's on the clipboard says. For instance, screenshots taken on a retina display and copied to the clipboard will open up with a DPI of 144.
If you have an image on the clipboard, you can now use the Edit ▸ Paste menu item from the start window to make a new image.
New option when creating a crop preset to remember the location of the saved crop, or otherwise have it centered in the canvas.
Fixed Stuff:
Fixed a bug that kept you from cropping two documents at once.
Fixed a bug where resizing the window with the option and command keys down (which will scale your image) wasn't showing the correct preview.
Fixed a bug where sometimes you couldn't add filters to a newly created layer mask.
Fixed a problem where you'd sometimes get transparent edges on images when importing a raw image that was scaled down.
Fixed a bug where bezier lines with no height or width were causing Acorn headaches.
Fixed a bug where the stepper brush size control in the smudge palette wasn't working.
Fixed a crash when trying to print an image which has a Japanese file name.
Fixed a crasher where trying to craftily nest groups inside of themselves would cause Acorn to spin into infinity.
The grid no longer disappears when you perform a free rotate on the canvas.
Fixed a redraw problem when moving bitmap layers when zoomed at 75%
Fixed a bug where some filters on shape layers wouldn't merge down correctly.
Fixed a scaling bug where pixels near edges would sometimes get stretched out.
Fixed a bug where an image and window that was greater than 2048 pixels would cause garbage to show up on the canvas (if you had a NVIDIA GeForce GT 120 GPU).
Fixed a crasher when dragging a specific type of image from Safari onto Acorn's dock icon.

New Stuff:
A New "Radial Gradient Blur", which is sort of a like a vignette, but with a blur. It's awesome, try it out.
You can now change change the depth of an image to 16 bits per component with the Image ▸ Image Depth menu item. Hello deep images!
RAW files are now opened as 16 bit per component / 64 bit pixel images.
The default color profile has now been changed to sRGB. (You can also change the default profile in Advanced prefs).
All drawing is now going directly through OpenGL, which makes things quite a bit faster.
You can now cycle through a layer's blend modes with Option Shift + or Option Shift - keyboard shortcuts.
You can now share images with Flickr, Twitter, Facebook, iPhoto, Aperture, and other services using the File ▸ Share menu item.
The Gaussian Blur filter now has a popup menu item to choose between clamping, blending, or doing nothing when blurring your image.
The smudge and clone tools no longer share brush sizes with the burn and dodge tools.
The pencil tool has been revamped with pixel editing in mind, making perfect squares to help you make perfect pixel art.
You can now set the blend mode for the pencil tool, and in addition to this there's a new "Copy" blend mode for the pencil tool which will replace the brushed pixels with the selected color exactly, instead of blending (which is awesome if you're using a color with alpha in it).
The eraser tool now has a softness option, which replaces the antialias checkbox.
The brush slider now grows and shrinks in size at a manageable yet very nice speed when you scrub back and forth.
The crop palette now has an option to keep the aspect ratio of your crop bounds when saving a new preset.
Added a new menu item to flatten all layer styles/filters in a document. Open up the Layers menu, hold down the option key, and the "Flatten Layer Filters" menu item changes to "Flatten All Layer Filters".
The color picker will now pick up alpha correctly if used over an Acorn canvas. The colorspace for the picked color is now calculated correctly as well.
If you use the arrow keys with a selection (and a selection tool is active) and hold down the option key, Acorn will copy the selection in the direction you press with the keys, thus extending the selection by a pixel (or 10 if you hold down the shift key).
Minor New Thing: The Levels and Curves now remember their window placement between uses.
Changes:
Holding down the option key with a bitmap drawing tool while on a shape layer will now pickup a color from the shape layer.
The Levels filter got some tweaks.
Bumped up the max font size from 1000 pt to 9999 pt.
No longer snapping to the guides if they aren't visible.
Removed the blend mode option for the grid since it slowed things down too much.
Using the View ▸ Zoom To ▸ Fit in Window menu item while in full screen will now re-center your canvas.
Bug Fixes:
Fixed a bug where non-contiguous wand selections wouldn't work right if the target color had transparency in it.
Fix: When resizing the crop bounds by an edge with the shift key down, it'll now keep it's aspect ration (previously this only worked if you used a corner to resize).
Fixed a bug where changing the default color profile for new images wouldn't take effect until you restarted Acorn.
Fixed a bug where the Tilt Shift filter wouldn't draw right when you were making a selection.
Fixed a bug where using the auto levels button in the Levels window would sometimes cause portions of your image to go black for the preview.
Fixed a bug where the rect selection would clip sometimes if you were zoomed way out on an image.
Fixed a bug where using the subtract selection mode would not clear the selection if you subtracted the whole selection.
Fixed a bug where group layer thumbnail previews weren't drawn tall enough in the layers list when you added a mask.
Fixed a bug where the canvas wouldn't update correctly when moving 1px high shapes with the arrow keys.
Fixed a bug where a shape stroke could only be set by pressing the enter key in the shape palette.
Fix: You can now set the opacity of layer masks.
Fixed a bug with selecting vertical bezier paths with only two anchors.

Fixed a bug where applying a filter to a selection wouldn't work when using the menu item and the layer filters window wasn't already up.
Fixed a bug where the layer thumbnail wasn't showing a moved selection in bitmap layers.
Layers with the random noise filter added to it now look better when zoomed out.
Fixed a bug where checking / unchecking the "preserve transparency" option in the random noise filter wouldn't always update the whole canvas.
Fixed a bug where merging layers while doing a layer transform would cause your transform to be lost, instead of asking if you wanted to apply or commit it.
The "New Layer from Selection" command will apply layer filters first for the new layer.
Fixed a problem where you wouldn't get the right cursor while transforming a bitmap layer after rotating a little bit.
Fixed some bugs with the Brush Designer where you couldn't enter zero for certain brush settings.
You can now export brushes from the Brush Designer using the File ▸ Export… menu item.
Fixed a bug where clearing a selection on a bitmap layer when it wasn't the active layer would sometimes cause cut out and moved bits to not be composited to the layer and - well, it's complicated. And now it's fixed.
Fixed a crasher caused by closing the shape popover window by pressing the escape key and closing the main window later on.
Certain selection commands will no longer throw up a sheet when working on locked files.
Fixed a bug when resetting the Grid, Checkerboard, and Pixellate filters would cause the center point to show up in the wrong spot.
Change: The Pixellate filter no longer clamps the input image to it's edges. The reason Acorn used to do this to stop the natural transparent edges from appearing. The reason why it was taken out was because it created all kinds of funky side effects with the non-destructive nature of the filters. If you're getting transparent edges, change the input center of the filter to a different value, or adjust the scale of the filter to be a whole multiple of the image size.
Fixed a problem where the sheet was opening too high when saving a preset for the crop tool.
Fixed some bugs relating to drag + drop from the layers list into the canvas, and option + drag (to make a copy of the current bitmap layer) directly in the canvas.
Changed the new document tab order so that moving from the width field goes directly to the hight field, and then the unit popup after that.
Fixed a glitch where moving the canvas from a retina to non retina display would cause the checkerboard background to move a little.
Fixed a bug where the New View window was scaling incorrect when moving from a regular display to a retina display.
Change: Window ▸ New View windows are now offset by 20pt from the original image instead of matching the frame exactly.
Fixed a bug where the checkered background for the Window ▸ New View window wasn't drawing correctly on retina displays.
Fixed a bug where the About box and Feedback window were stuck behind Acorn's welcome window.
Fixed a bug where bezier shapes were drawing the wrong bounding boxes.
Fixed a regression where filters weren't working on layer masks.
Change: PSD files are now opened up as Untitled documents since Acorn won't ever save them in place (export only) and it also works better with autosave and versions support now.
Fixed some problems when trying to use selection tools on layer masks that belonged to group and shape layers.
Fixed a bug where the cursor wouldn't always update correctly when moving in and out of a selection.
Fixed a bug where the option to turn of antialiasing for shapes wasn't working with the text tool.
Fixed a bug where Acorn would sometimes restore an empty selection when opening a .acorn file.
Fixed a bug where making a selection from a layer wouldn't update the selection size in the selection palette.
Fixed a problem where the layers list would not scroll to the selected layer when you selected a new layer in the canvas.
Better defaults for shape settings when you launch Acorn for the first time.
Fixed a crasher that would sporadically happen when you register Acorn.

New Stuff:
The magic wand selection tool now has an option for contiguous or non-contiguous selections. In addition to this, if you use the magic wand tool on a shape layer with the contiguous option turned off, it effectively works as a "select all shapes with this fill color" tool. Which is pretty rad if you have a bunch of shapes that you want to change the colors on.
New File ▸ Layer Export… menu item, which will export a single layer out of Acorn. In addition to this, if you have a shape layer that you want to export and it doesn't have any layer styles associated with it, a pure vector PDF will be written out.
The contextual menu now has a copy of the Layer ▸ Shape Align and Size menu for working with selected shapes quickly.
New layer blend modes: Divide, Lighter Color, Darker Color, Hard Mix, and Subtract.
New Generator ▸ Sunburst filter, which lets you make some awesome backgrounds.
Changes:
Guides are now drawn when you free rotate your canvas.
In the Image Browser window (which you can open via File ▸ Open Folder… menu item), the little icons on either side of the zoom slider will now increase or decrease the zoom level of the preview images when clicked.
The "Open Image in Acorn" service will now work with selected files when used from the Finder.
If you're editing a file with Autosave + Versions turned on, and that file happens to be locked, Acorn will no longer warn you to duplicate it if you're only applying selections (which don't alter the image).
Holding down the shift key while rotating when using the Layer ▸ Rotate and Transform ▸ Scale and Rotate menu item will snap the rotation to 45° increments.
Increased the amount you can magnify an image with the zoom slider from 1000% to 2000%, which should help out Retina MBP owners. Pro tip: did you know you can click the little icons on either side of the slider to zoom in or out in a controlled fashion? And the zoom tool (shortcut key 'z') can zoom in even more than the slider!
Remove FXG as an exportable image format, since Adobe seems to have abandoned it.
Pressing the return or enter key on a shape layer no longer merges it down. Why did Acorn ever do this? I wish I knew, but it was on purpose.
Slight change in behavior with Image ▸ Trim to Edges: If a bitmap layer has pixels outside the canvas bounds, they are no longer taken into account when trimming down the size of the image.
Added a new property for JSTalk/JavaScript filters to show up in the Actions menu: set ACIsAction=true in the header section of your script.
Updated the JSTalk/JavaScript plugin to work on Group layers.
The "Plus Lighter" blend mode was renamed to "Linear Dodge", to more closely match other image editors.
The "Plus Darker" blend mode was renamed to "Linear Burn", to more closely match other image editors.
The blend modes were reordered to more closely match other image editors.
New Stuff for Scripters:
Some new plugin APIS: A new method on CIImage: - (BOOL)writeToURL:(NSURL*)fileURL withUTI:(NSString*)uti A new method to implement for the ACPlugin protocol- (NSNumber*)validateForLayer:(id)layer; A new method for finding the opaque bounds on layers: - (NSRect)opaqueBounds;
You can also now mess with a layer mask with these new methods on ACLayer: - (void)setLayerMaskImage:(CIImage*)ciimage; - (id )mask; - (BOOL)maskIsLinked; - (void)setMaskIsLinked:(BOOL)value;
The plugin SDK has been moved to GitHub as well: https://github.com/ccgus/AcornSDK
Lots of Important Fixes:
Fixed a bug where sometimes the extension for your filename would disappear in the save sheet.
When using the various transform tools on a bitmap layer, the transform operation will now apply to the layer mask if it is linked.
Fixed a bug where sometimes text boxes would not get their line heights correctly scaled when resizing an image.
Fixed the little Purchase menu blip that you'd sometimes seen when starting up even though Acorn was registered already.
Various fixes with the magic wand tool, including little speed improvements.
Fixed a bug where you'd get interesting patterns in your selection in some cases with the magic wand tool.
Fixed a bug where Acorn thought it would sometimes still have a selection when using the magic wand tool + intersection selection mode, where no intersection was produced.
When exporting as PDF, Acorn will now create a document which respects the current DPI of the image.
Fixed a bug with the Scale and Rotate transform tool, where you couldn't enter fractional values for the rotation field in the palette.
Fixed a bug with the Add Border to Layer filter with Retina displays.
Fixed a bug where zooming with the scroll wheel (hold down the option key for this!) would put the canvas in unexpected locations on retina displays.
Fixed a bug where using the Scale And Rotate menu item on an even width/height image with a rotation of 180° would offset the image by 1 pixel.
Fixed a bug where using the Edit ▸ Fill menu item to fill your image with a pattern would blur the pattern image.
Fixed a bug in Web Export where the Save button wasn't enabled right away if you switched from saving as a PNG to a JPEG while the PNG was still being processed.
Fixed a bug where the File ▸ Add Images… menu item would let you select a PDF, but wouldn't actually import it as a new layer to the image.
Using the tab key to change fields in the Acorn Automator Crop Image Action (say it five times fast!) will no take you to the next field.
Fixed a bug where sometimes flipping a layer vertical or horizontal would trim out some of the pixels.
Fixed a bug where the trim bounds of a shape layer was sometimes wrong with multiple shapes.
Various Retina display fixes with layered screenshots and zoom to fit, among other miscellaneous things.
Fixed a bug where the file extension would not change correctly when changing the filetype in the Export sheet.
Fixed a bug where Acorn would crash when making a new document if there was bad data on the clipboard.
When duplicating a document, Acorn will notice if the rulers are showing and turn them on for the duplicated document if needed.
Fixed a bug where Acorn wasn't auto-registering from MAS versions of Acorn that were sandboxed.
Fixed a bug with the "New Image with Curved Drop Shadow" plugin on Retina MacBook Pros.
Fixed a bug with Trim to Edges, where sometimes the canvas would grow if a layer extended outside the bounds of the canvas.
Fixed a crasher when web exporting a completely transparent image with the trim and matte buttons checked.

New in Acorn 3.5 Build 6381 Alpha 1 (Aug 21, 2012)

New in Acorn 3.3.1 Build 6365 Beta 1 (Jul 30, 2012)

New in Acorn 3.3 Build 6335 (Jul 16, 2012)

New Stuff:
Retina Canvas- Your images look absolutely beautiful on the new Retina MacBook Pros with a a 1 to 1 pixel mapping from the image to the screen. Hello super awesome high resolution!
Trim out Selection! If you have a fully vertical or horizontal selection, holding down the option key will turn the Image ▸ Trim to Edges menu item into "Trim out Selection" which will slice out the current selection and squish the two endpoints of your image together (bitmap layers only).
Smart Layer Export! Its like slices, but smarter.
You can now convert the current selection into a layer mask just by invoking the Layer ▸ Add Layer Mask menu item when your selection is active. Rad.
Awesome new feature- Reselect! The Select ▸ Reselect menu item will now remember whatever the last selection for your image was. So you can make up some fancy selection, clear it, and then use it again later on.
New shortcuts for making selections from layers. Holding down the command key while clicking on a layer in the layers list has made a selection based off using the layer image as a mask. Now if you hold command + the shift key, the new mask will be added to an existing selection, command + option will subtract, and command + shift + option will intersect.
In the resize canvas sheet, you can now use Command 1 through 9 on the number keypad to choose an anchor for the image. Command-1 corresponds to the lower left, Command-9 is the top right, Command-5 is in the middle, etc.
New iPad presets in the new document window.
Subtraction and intersection selection modes now works for the magic wand tool.
The text system got a little makeover so rendering more closely matches what you see when editing a text box.
You can now close open paths using the Layer ▸ Shape Align and Size ▸ Close Path menu item.
Command-control-- can now be used as a shortcut to delete the selected layer style in the layer style palette.
New contextual menu for selected shape layers for Send to Back / Bring to Front.
The Web Export window now has a scaling option. The AppleScript and JSTalk interfaces have also been updated to take width and height properties.
Notes for the App Store version of Acorn which is now sandboxed:
The magic Acorn uses to automatically change the file type popup as you type in the Save sheet no longer works, for your security.
Using JSTalk to open up images that have not been recently opened will fail.
Fixes:
Fixed a bug where selecting a shape close to a snap point would cause it to move, even if you hadn't moved the mouse after selecting it.
Fixed a bug in the image resize sheet where certain calculations of the canvas size were off by 1.
Fixed a bug where the Posterize Quartz Composition wouldn't show a good UI for setting its levels.
Fixed a bug where the layers list would lose the current selection when using its contextual item to delete a layer which wasn't currently selected
Fixed a bug where scaling an image with bezier paths wouldn't scale the path's stroke or gradient correctly.
Fixed a bug where the Hue Adjust layer style would show your saved style in radians instead of degrees.
Fixed a display issue with the ruler when you had units set to Centimeters.
Fixed a bug where origins on bitmap layers sometimes reset to zero when changing the color profile of the image.
If you've go the canvas origin set to the top left, then the canvas grid will correctly now set its origin to this point.
Once again, if you've go the canvas origin set to the top left then the palette's entry for the bounds of a selected shape are calculated correctly.
Fixed a bug where a PSD layer limit was incorrectly being applied to 10.6 users (Sorry guys! It was only supposed to hit folks on 10.7.0-10.7.3! If you're running 10.7.4 or later, you're also OK. If not- what are you waiting for?)
The iPhone Retina preset now has the same aspect ration of the old gen iPhone preset.
Fixed a bug where resizing an image with the Simple Affine scaling algorithm would sometimes show a transparent edge on the right side of the image.
Shape selection behavior when zoomed way in is better.
Fixed a bug where merging of the visible layers would cause the final layer to always be placed at the bottom of the layer stack.
Fixed a bug where expanding the canvas to fit the layers with a selection would sometimes move the selection to the wrong spot.
Fixed some problems when you were zoomed way in and moving bezier shapes around + snap to pixels turned on.
Fixed a regression where switching between two images would cause Acorn to forget which layer was selected.
The opacity slider for the inner shadow layer style now shows as a percentage instead of a decimal number.
Fixed a bug where sometimes moving the very first element of a bezier curve would cause your endpoints to go a little nuts.
Fixed a bug where using the magic wand on a layer with multiple selections and transparent areas would sometimes redraw the transparent areas making it more opaque. Which probably isn't what you wanted.
Fixed a bug on the OS THAT SHALL NOT BE NAMED (10.8) where some JSTalk scripts would not work.
Fixed a 10.7 bug where saving a document to a file that was already open in another window would cause Acorn to hang.
Squashed a bug where starting a layered export to PNG and then canceling at just the right time would cause Acorn to beep at you on the next save.
Fixed a bug where using the magic wand to add to a selection would sometimes shift the selection around.
Fixed a bug where you could nudge the current crop marks outside the canvas when using the arrow keys (only when the crop was set to stay in the canvas).
Copying a bitmap layer would sometimes cause changes from the original layer to show up on the copied layer. We have rectified this situation.
Copy on shape layers no longer adds a border for the PDF representation.
Other interesting tidbits:
Added a "New Shape Layer" menu item to the action menu of the Palette.
Changed the "Zoom Tool" menu item to "Zoom" (under the View ▸ Tools menu), and renamed the Window ▸ Zoom menu item to "Zoom Window" (Pages does this as well, to avoid confusion with custom shortcuts).
When transforming a selection, you can now use the arrow keys to move your selection around. Hold down the shift key to move 10x as fast!
The trick to resize the brush tool (by holding down the control and option keys, click on the canvas, and moving the mouse back and forth) now works for the smudge, dodge, burn, and clone tools.
If the brush or pencil tool is selected, pressing the '5' will set the opacity of the tool to 50%, '3' to 30%, and '0' to 100%. Previously this would change the opacity of the layer (which is still true when the move and other tools are selected).
When trimming an image, the bounds for invisible layers will no longer be taken into account.
If you start a selection and move the mouse outside the window and stop, Acorn would stop the selection even if you had more room to scroll around in. In 99% of the cases, this isn't what you wanted- so now Acorn will continue scrolling if you stop moving the mouse outside the window.
Trying something new- previously if you managed to start creating a shape without a fill or stroke, Acorn would turn on the fill. In 3.3 we've changed that to turning on the stroke with a value of 1.
Undo when moving vector shapes is quite a bit faster.
Reworked the warning you get when trying to trim an image without any transparent edges. It is now 84% more accurate.
The tool palette no longer goes transparent in full screen, because this was kind of annoying. You can use the Tab key to quickly toggle the tool palette's visibility.
The shortcut to show and hide the grid now works when you're rotating the image.
When merging visible layers, Acorn will combine all the images into a new layer - and now it'll use the name of the selected layer (assuming it's visible) for the new composited image.
The layer styles fx symbol in the layers list now dims when layer styles are disabled.
Various little speed improvements when layers styles are enabled.
You can now remove a gradient stop-point by moving it off the edge of the preview either left or right, in addition to below as it's always been.
Flipping a layer in place now keeps it within the layer's opaque bounds.
When you have a group layer selected and you copy + paste to a new image- instead of a composite of all the images the whole group with layers preserved are pasted.
You can now use the various selection tools on a hidden layer.
If you have multiple points selected in a bezier path, pressing the delete key now removes all of them instead of the first one Acorn comes across.
New API for plugin authors- the document class now implements firstLayerWithName:, which will return the first layer it finds with the given name.
The formatters in the filter panels no longer use commas in the numbers because that got really annoying.
Now signing with Developer ID, for your security.

Acorn had to change its Automator actions a bit. If you have an existing Automator workflow make sure to open it up and double check that Acorn's workflow items are still there.
Fixed a hang where scaling down certain text would crash Acorn.
Fixed a bug where Acorn was not able to draw straight lines with the brush tool when you were using a stylus + shift clicking between points.
Fixed a bug where making a rectangle selection using two guides would add an extra pixel of width (or height) to the selection.
Fixed a bug where you couldn't start a new selection within another selection when you had the selection mode set to addition (and you weren't holding the shift key down).
Fixed a bug where the canvas resize sheet was setting the wrong initial values when inches were selected in the unit popup.
Fixed a problem with certain blend modes and shape layers.
Fixed a problem where bringing up the resize image sheet while you were croping mode would cause bad things to happen.

New in Acorn 3.0.2 Beta 1 Build 5363 (May 6, 2011)

New in Acorn 3.0.1 Build 5359 (May 5, 2011)

Fixed a trimming bug.
Fixed a bug where the colors in the filter panel were different than the colors in the canvas when a preview was shown.
You can now change the levels in a layer mask.
If Acorn can't seem to open up a layered PSD, it'll try and open up its composite layer instead.
Fixed a redraw problem with rotated bezier paths.
Fixed a bug where you could uncheck the "Keep aspect ratio" option when scaling an image with the Lanczos scaling algorithm.
Fixed a bug where creating a new graphic on a shape layer with a really big drop shadow layer style would draw incorrectly.
Generator layer styles (like circles, gradients, checkerboard) now have an overlay option which is enabled by default. We've also removed the source atop blend mode, since this did the exact same thing as the overlay button does now.
Fixed a bug where the bold button in the font palette wasn't working correctly.
Fixed a bug with moving a selection on a bitmap where cutting was involved and it's much too involved to actually explain here. But it works as expected now, so that's good.
Fixed a bug where the registration certificate (non app store versions) would show your old registration number.
Fixed a bug where the canvas wouldn't show up on new documents for certain document sizes.
Fixed a PSD import bug where the pass through blend mode for layer groups wasn't showing up correctly.

Fixed a regression when Acorn wouldn't remember if you had the fill shape button turned off between launches.
Fixed a bug where the preview for a layer style wouldn't show up correctly on group layers with masks.
Fixed a bug where the a mask + layer style on a shape layer was composited in the wrong order.
Fixed a bug where paste into wasn't working.
Fixed a bug where minimizing the window would cause graphics to display badly later on.
Now copying PNG data to the clipboard, making it more compatibly with mail clients.
If you hold down the option key when opening a PSD, Acorn will now give you the option to open it up with multiple layers, or a single composite layer.
Two new layer style filters: Monotone and False Color.
Fixed a bug where trying to change the opacity while you were in a transform operation would cause Acorn to ask you to commit the operation.
Fixed a bug where layers with an opacity setting would sometimes draw funky pixels at the opaque edges of the image.

New in Acorn 3.0 Build 5300 (Apr 13, 2011)

New: Layer styles!
New: Quick Mask! Press the 'q' key to toggle it.
New: Instant Alpha! Instant alpha is a new tool that works like a magic eraser. You can select it from the erase palette, or press 'e' to toggle between the eraser and instant alpha.
New: Live gradients.
New: Gradients on text and shapes!
New: Multistop gradients! Drag and drop colors into the gradient preview window to add, double click on a slider to change it's color + opacity. Option-drag to duplicate a color, drag it down to delete.
New: You can now export a document as a layered PSD or PDF.
New: You can now rotate shape and text objects.
New: Acorn now has a new menu item in the Dock when running: "New Image from Clipboard", which will pop open a new image if you have an image on the clipboard.
New: You can now add and subtract points from a bezier curve.
New: If you use the canvas contextual menu to add a guide, it'll autofil the location based on where you clicked.
New: Layer styles now have presets, and you can export and open new ones. Trade with your friends, collect them all!
New: Nenu item: Layer ▸ Commit Layer Style, which makes a layer style permanent for bitmap layers.
New: Acorn will now give a little warning when you try and make an image that's over 50 megapixel.
New: Holding down the option key when clicking on the (fx) icon in the layers list will toggle that layer's layer style visibility.
New: The drop shadow filter now has an opacity slider.
New: 5 new fonts- Lobster, Chunk Five, Prociono, OFL Sorts Mill Goudy, and Raleway Thin.
New: Additional scripting api to insert layers from a path on disk (via jstalk scripting): var newLayer = doc.baseGroup().insertLayerWithImagePath_atIndex("/Volumes/srv/Users/gus/Pictures/AnotherImage.png", 1).
New: The shape tools now have tooltips above them.
New: New Filter ▸ Stylize ▸ Inner Shadow filter + layer style.
New: Crop presets! You can now save (and choose) custom presets for the crop tool.
New: If a layer mask is selected, and you use the Paste command - the current clipboard will be pasted into the selection mask instead of a new layer being created.
New: Bevel layer style + filter.
New: Vertical Distribute Center and Horizontal Distribute Center menu commands under the Layer ▸ Shape Align and Size menus. Select 3 or more shapes to enable these commands.
New: You can now drag and drop color swatches onto a layer in the canvas to fill that layer with the dropped color.
New: New Opacity filter which will change the opacity of a given image. This is useful if you have a bunch of filter operations and you'd like to change the opacity of an image in the middle of it.
New: You can now delete guides by dragging them off the canvas.
New: The canvas contextual menu now has an item named "Use Image as Desktop Picture", which will set the current canvas to your desktop image.
New: You can now drag and drop quartz compositions onto Acorn, and it will prompt you to let Acorn auto install the composition to ~/Library/Compositions.
New: New "Circles" filter under the Generator filters. It adds a bunch of concentric circles in your choice of color.
New: You now have the option to use inches or centimeters in the rulers or when making new images.
New: There's a new pref to autoload a palette when using keyboard shortcuts for tools (such as 'b' for brush, or 'v' for the arrow tool). With this option disabled, click on the icon for the corresponding palette to show up in the tools list. This makes it easier to switch back and forth from the shape or text tools to another tool, without losing the palette's focus.
Change: Batch closing all the windows (closing a window with the option key down) no longer closes the tool palette.
New: You can now add, delete, and disable layer masks from the canvas contextual menu.
New: You can now convert text into Bezier shapes.
New: Full Screen and Quick Mask buttons are now in the palette.

Change: The up and down arrow keys now work to change values in the Feather… selection dialog box.
Change: The auto-select layers option has moved to the move tool palette.
Change: Line spacing has been renamed to line height. There was a general issue where you could set negative values for line spacing, which worked sometimes- but it wasn't supported by the system text engine, so it didn't work all the time. So I've replaced it with Line Height, which should work out just as well (and which is supported).
Change: Removed the HDR filters category, since it was just confusing folks.
Change: The Snap To settings for documents are now application wide. The View ▸ Snap To menu item is gone, and it's been replaces with some settings in the Advanced preferences.
Change: If the current tool is the crop tool, and you use the Select All command, instead of a new selection being put on the canvas, the crop tool will be invoked with the canvas bounds as its size.
Change: When duplicating a layer, the newly duplicated layer is now automatically selected.
Change: In order to move guides now, you have to have the arrow tool selected.
Change: There's no longer a toggle switch for stroke width. It's either zero (off), or some other value which will draw it.
Change: The "new image from selection" and "new layer from selection" menu commands are now disabled when you are in quickmask mode.
Change: The Snap To prefs are now in the move palette.
Change: Eliptical and Rect selections will now snap to rulers for the start of the selection (previously only for the end of the selection).
