New in version 4.2.2
May 7th, 2015
- Critical security release for all previous versions and we strongly encourage you to update your sites immediately. Version 4.2.2 addresses two security issues:
- The Genericons icon font package, which is used in a number of popular themes and plugins, contained an HTML file vulnerable to a cross-site scripting attack. All affected themes and plugins hosted on WordPress.org (including the Twenty Fifteen default theme) have been updated today by the WordPress security team to address this issue by removing this nonessential file. To help protect other Genericons usage, WordPress 4.2.2 proactively scans the wp-content directory for this HTML file and removes it. Reported by Robert Abela of Netsparker.
- WordPress versions 4.2 and earlier are affected by a critical cross-site scripting vulnerability, which could enable anonymous users to compromise a site. WordPress 4.2.2 includes a comprehensive fix for this issue.
- The release also includes hardening for a potential cross-site scripting vulnerability when using the visual editor.
- In addition to the security fixes, WordPress 4.2.2 contains fixes for 13 bugs from 4.2.1, including:
- Fixes an emoji loading error in IE9 and IE10
- Fixes a keyboard shortcut for saving from the Visual editor on Mac
- Fixes oEmbed for YouTube URLs to always expect https
- Fixes how WordPress checks for encoding when sending strings to MySQL
- Fixes a bug with allowing queries to reference tables in the dbname.tablename format
- Lowers memory usage for a regex checking for UTF-8 encoding
- Fixes an issue with trying change the wrong index in the wp_signups table on utf8mb4 conversion
- Improves performance of loop detection in _get_term_children()
- Fixes a bug where attachment URLs were incorrectly being forced to use https in some contexts

- We’re freshening up the plugin install experience. You’ll see some early visual changes as well as more information when searching for plugins and viewing details. (#28785, #27440)
- Selecting a language when you run the installation process. (#28577)

- TinyMCE received a major update, to version 4.0. Any editor plugins written for TinyMCE 3.x might require some updates. (If things broke, we’d like to hear about them so we can make adjustments.) For more, see TinyMCE’s migration guide and API documentation, and the notes on the core development blog.
- WordPress 3.9 now uses the MySQLi Improved extension for sites running PHP 5.5. Any plugins that made direct calls to mysql_* functions will experience some problems on these sites. For more information, see the notes on the core development blog.
New in version 3.8.2 (April 9th, 2014)

New in version 3.9 Beta 1 (March 12th, 2014)
- Updated TinyMCE, the software powering the visual editor, to the latest version. Be on the lookout for cleaner markup. Also try the new paste handling — if you paste in a block of text from Microsoft Word, for example, it will no longer come out terrible. (The “Paste from Word” button you probably never noticed has been removed.) It’s possible some plugins that added stuff to the visual editor (like a new toolbar button) no longer work, so we’d like to hear about them (#24067). (And be sure to open a support thread for the plugin author.)
- Added widget management to live previews (the customizer). Please test editing, adding, and rearranging widgets! (#27112) We’ve also added the ability to upload, crop, and manage header images, without needing to leave the preview. (#21785)

New in version 3.8 (December 13th, 2013)
- Named “Parker” in honor of Charlie Parker, bebop innovator

- Modern aesthetic - The new WordPress dashboard has a fresh, uncluttered design that embraces clarity and simplicity.
- Clean typography - The Open Sans typeface provides simple, friendly text that is optimized for both desktop and mobile viewing. It’s even open source, just like WordPress.
- Refined contrast - We think beautiful design should never sacrifice legibility. With superior contrast and large, comfortable type, the new design is easy to read and a pleasure to navigate.
- WordPress on every device:
- We all access the internet in different ways. Smartphone, tablet, notebook, desktop — no matter what you use, WordPress will adapt and you’ll feel right at home.
- High definition at high speed:
- WordPress is sharper than ever with new vector-based icons that scale to your screen. By ditching pixels, pages load significantly faster, too.
- Admin color schemes to match your personality
- WordPress just got a colorful new update. We’ve included eight new admin color schemes so you can pick the one that suits you best.
- Color schemes can be previewed and changed from your Profile page.

- The new themes screen lets you survey your themes at a glance. Or want more information? Click to discover more. Then sit back and use your keyboard’s navigation arrows to flip through every theme you’ve got.
- Smoother widget experience:
- Drag-drag-drag. Scroll-scroll-scroll. Widget management can be complicated. With the new design, we’ve worked to streamline the widgets screen.

New in version 3.8 Beta 1 (November 22nd, 2013)

- The dashboard homepage has been refreshed, poke and prod it.

- Fix a warning that may occur in certain setups while performing a search, and a few other notices.
New in version 3.7 (October 28th, 2013)
- This release features some of the most important architectural updates we’ve made to date. Here are the big ones:
- Updates while you sleep: With WordPress 3.7, you don’t have to lift a finger to apply maintenance and security updates. Most sites are now able to automatically apply these updates in the background. The update process also has been made even more reliable and secure, with dozens of new checks and safeguards.
- Stronger password recommendations: Your password is your site’s first line of defense. It’s best to create passwords that are complex, long, and unique. To that end, our password meter has been updated in WordPress 3.7 to recognize common mistakes that can weaken your password: dates, names, keyboard patterns (123456789), and even pop culture references.
- Better global support: Localized versions of WordPress will receive faster and more complete translations. WordPress 3.7 adds support for automatically installing the right language files and keeping them up to date, a boon for the many millions who use WordPress in a language other than English.
- For developers there are lots of options around how to control the new updates feature, including allowing it to handle major upgrades as well as minor ones, more sophisticated date query support, and multisite improvements.
New in version 3.7 RC 1 (October 23rd, 2013)
- Automatic background updates for security and minor releases will update every 12 hours or so to the latest development version, and then email you the results.
New in version 3.7 Beta 1 (September 30th, 2013)
- If you’re running WordPress in another language, we’ll automatically download any available translations for official WordPress importers and the default themes. (More to come here.)
- Our password meter got a whole lot better, thanks to Dropbox’s zxcvbn library. Again, subtle but effective. Strong passwords are very important!
- Search results are now ordered by relevance, rather than just by date. When your keywords match post titles and not just content, they’ll be pushed to the top.
- Developers should check out the new advanced date queries in WP_Query.
New in version 3.6.1 (September 12th, 2013)
- Block unsafe PHP unserialization that could occur in limited situations and setups, which can lead to remote code execution.
- Prevent a user with an Author role, using a specially crafted request, from being able to create a post “written by” another user.
- Fix insufficient input validation that could result in redirecting or leading a user to another website.
New in version 3.6 (August 2nd, 2013)
- Includes a beautiful new blog-centric theme, bullet-proof autosave and post locking, a revamped revision browser, native support for audio and video embeds, and improved integrations with Spotify, Rdio, and SoundCloud.
- User Features:
- The new Twenty Thirteen theme inspired by modern art puts focus on your content with a colorful, single-column design made for media-rich blogging.
- Revamped Revisions save every change and the new interface allows you to scroll easily through changes to see line-by-line who changed what and when.
- Post Locking and Augmented Autosave will especially be a boon to sites where more than a single author is working on a post. Each author now has their own autosave stream, which stores things locally as well as on the server (so much harder to lose something) and there’s an interface for taking over editing of a post, as demonstrated beautifully by our bearded buddies in the video above.
- Built-in HTML5 media player for native audio and video embeds with no reliance on external services.

New in version 3.6 RC 2 (July 30th, 2013)
- Revisions so smooth
- We autosave your changes
- Data loss begone!
New in version 3.5.2 (June 22nd, 2013)
- This is the second maintenance release of 3.5, fixing 12 bugs.
- This is a security release for all previous versions and we strongly encourage you to update your sites immediately.

New in version 3.5 (December 12th, 2012)
- The most dramatic new change you’ll notice is a completely re-imagined flow for uploading photos and creating galleries. Media has long been a friction point and we’ve listened hard and given a lot of thought into crafting this new system.
- Includes a new default theme, Twenty Twelve, which has a very clean mobile-first responsive design and works fantastic as a base for a CMS site.

- Mobile: It’ll be easier to link up your WordPress install with our mobile apps, as XML-RPC is now enabled by default.
- Links: We’ve hidden the Link Manager for new installs.
- External libraries updated: TinyMCE 3.5.6. SimplePie 1.3. jQuery 1.8.2. jQuery UI 1.9 (and it’s not even released yet). We’ve also added Backbone 0.9.2 and Underscore 1.3.3, and you can use protocol-relative links when enqueueing scripts and styles. (#16560)

- oEmbed: We’ve added support for a few oEmbed providers, and we now handle SSL links. (#15734, #21635, #16996, #20102)

- Address pagination problems with some category permalink structures.
- Avoid errors with both oEmbed providers and trackbacks.

- Allows for a technique commonly used by plugins to detect a network-wide activation.

- Fixes a few security issues and contains some security hardening. The vulnerabilities included potential information disclosure as well as an bug that affects multisite installs with untrusted users.
New in version 3.4 (June 14th, 2012)
- Includes significant improvements to theme customization, custom headers, Twitter embeds, and image captions.
- For Users:
- The biggest change in 3.4 is the theme customizer which allows you to play around with various looks and settings for your current theme or one you’re thinking about switching to without publishing those changes to the whole world. For themes that support it, you can change colors, backgrounds, and of course custom image headers. We have more planned for the customizer down the road.
- Throughout the rest of the admin you’ll notice tweaks to make your everyday life easier. For example, if you have lots of themes we’ve made it quicker to browse them all at once without paging. We’ve made it possible to use images from your media library to populate custom headers, and for you to choose the height and width of your header images.
- Expanded the embed support to include tweets: just put a Twitter permalink on its own line in the post editor and we’ll turn it into a beautiful embedded Tweet. And finally, image captions have been improved to allow HTML, like links, in them.
- For Developers:
- There are hundreds of under-the-hood improvements in this release, notably in the XML-RPC, themes, and custom header APIs, and significant performance improvements in WP_Query and the translation system. The Codex has a pretty good summary of the developer features, and you can always dive into Trac directly.
New in version 3.4 RC 3 (June 12th, 2012)
- Fixed a few lingering issues with the new live preview feature, as well as with custom headers and backgrounds.
New in version 3.4 Beta 4 (May 3rd, 2012)

New in version 3.3.2 (April 21st, 2012)
- A security update for all previous versions.
- Three external libraries included in WordPress received security updates:
- Plupload (version 1.5.4), which WordPress uses for uploading media.
- SWFUpload, which WordPress previously used for uploading media, and may still be in use by plugins.
- SWFObject, which WordPress previously used to embed Flash content, and may still be in use by plugins and themes.
- Limited privilege escalation where a site administrator could deactivate network-wide plugins when running a WordPress network under particular circumstances, disclosed by Jon Cave of our WordPress core security team, and Adam Backstrom.
- Cross-site scripting vulnerability when making URLs clickable, by Jon Cave.
- Cross-site scripting vulnerabilities in redirects after posting comments in older browsers, and when filtering URLs. Thanks to Mauro Gentile for responsibly disclosing these issues to the security team.

New in version 3.3.1 (January 4th, 2012)
- Fixes 15 issues with WordPress 3.3, as well as a fix for a cross-site scripting vulnerability that affected version 3.3.
New in version 3.3 (December 13th, 2011)
- For Users - Experienced users will appreciate the new drag-and-drop uploader, hover menus for the navigation, the new toolbar, improved co-editing support, and the new Tumblr importer. We’ve also been thinking a ton about what the WordPress experience is like for people completely new to the software. Version 3.3 has significant improvements there with pointer tips for new features included in each update, a friendly welcome message for first-time users, and revamped help tabs throughout the interface. Finally we’ve improved the dashboard experience on the iPad and other tablets with better touch support.
- For Developers - There is a ton of candy for developers as well. I’d recommend starting your exploration with the new editor API, new jQuery version, better ways to hook into the help screens, more performant post-slug-only permalinks, and of course the entire list of improvements on the Codex and in Trac.

- More than 350 tickets closed
New in version 3.2 Beta 2 (May 26th, 2011)

- Performance improvements like you wouldn’t believe. What’s that mean? Things are faster!
- Distraction-free Writing. The visual editor’s full-screen composing experience has gotten a major overhaul, and is now available from HTML mode, too. More than ever, WordPress allows you to focus on what matters most — your content.
- Admin UI Refresh. The last major redesign of the WordPress admin was in 2008. This isn’t a major redesign, just a little facelift to keep us feeling young. WordPress turns 8 later this month, you know.
- New Default Theme. Introducing Twenty Eleven, based on the popular Duster theme. Rotating header images, post format support, and more.
- Browse Happy. WordPress is made to work with modern browsers. If you visit your Dashboard using an outdated web browser, we’ll let you know there’s a newer version available.
- Admin Bar. We’ve added more links to the admin bar to make it even more useful.
New in version 3.1.2 (April 26th, 2011)
- A security release for all previous WordPress versions.
- This release addresses a vulnerability that allowed Contributor-level users to improperly publish posts.
- The issue was discovered by a member of our security team, WordPress developer Andrew Nacin, with Benjamin Balter.
- The developers suggest you update to 3.1.2 promptly, especially if you allow users to register as contributors or if you have untrusted users. This release also fixes a few bugs that missed the boat for version 3.1.1.
New in version 3.1 (February 24th, 2011)
- WordPress 3.1 “Reinhardt” is named in honor of the jazz guitarist Django Reinhardt.
- This release features a lightning fast redesigned linking workflow which makes it easy to link to your existing posts and pages, an admin bar so you’re never more than a click away from your most-used dashboard pages, a streamlined writing interface that hides many of the seldom-used panels by default to create a simpler and less intimidating writing experience for new bloggers (visit Screen Options in the top right to get old panels back), and a refreshed blue admin scheme available for selection under your personal options.
- There’s a bucket of candy for developers as well, including our new Post Formats support which makes it easy for themes to create portable tumblelogs with different styling for different types of posts, new CMS capabilities like archive pages for custom content types, a new Network Admin, an overhaul of the import and export system, and the ability to perform advanced taxonomy and custom fields queries.
New in version 3.1 RC 4 (February 8th, 2011)
- includes the security fixes and enhancements included in 3.0.5 and addresses about two dozen additional bugs.
- Includes fixes for:
- Deleting a user and reassigning their posts to another user.
- Marking multiple users or sites as spam in multisite.
- PHP4 compatibility.
New in version 3.0.5 (February 8th, 2011)
- This security release is required if you have any untrusted user accounts, but it also comes with important security enhancements and hardening. All WordPress users are strongly encouraged to update.
- Two moderate security issues were fixed that could have allowed a Contributor- or Author-level user to gain further access to the site.
- One information disclosure issue was addressed that could have allowed an Author-level user to view contents of posts they should not be able to see, such as draft or private posts.
- Two security enhancements were added. One improved the security of any plugins which were not properly leveraging our security API. The other offers additional defense in depth against a vulnerability that was fixed in previous release.
New in version 3.1 RC 3 (January 24th, 2011)
- The biggest change is the removal of AJAX list tables, which had been an effort to move all of our list-style screens to full AJAX for pagination, searches, and column sorts, and to consolidate the list-style screens into a single API that plugins could leverage. Unfortunately, with more testing came realizations that there were too many major bugs and usability issues with how the functionality was implemented, so we’ve spent the last week rolling back the most important portions of the feature.
- For users: AJAX has been entirely disabled for the list tables. We hope to bring this back again, in a form that is properly and fully implemented, in a future release. Column sorting remains, but everything else has returned to its 3.0 state.
- For developers: The entire list table API is now marked private. If you attempt to leverage new components of the API, you are pretty much guaranteeing that your plugins will break in a future release, so please don’t do that. :-) We hope to enable all the fun new goodies for public use in a future release.
- This is the only way it could be prevented any regressions in functionality and usability from WordPress 3.0 to 3.1. That’s right, users and plugin authors can still do everything you used to be able to do (and a little bit more).
- Because of the code churn between RC2 and RC3, this release candidate needs a lot of testing. Every list screen needs testing. In particular, the comment moderation screen needs testing, especially with keyboard shortcuts (if you didn’t know about those, now’s your chance to try them out).
- Other fixes in RC3 include:
- Properly display the author dropdown in Quick Edit
- Various important fixes to numerous taxonomy query variables
- Fixes to the theme deletion process
- Fixes to pages used for posts
- IIS and Multisite: Avoid resetting web.config on permalink save
- Properly validate post formats and their rewrite rules
New in version 3.1 RC 2 (January 3rd, 2011)
- The security fixes included in WordPress 3.0.4
- Fix issues related to handling a static front page
- Fixes and enhancements for the pagination buttons
- Fix searching for partial usernames
- Properly reactivate plugins after editing them
- Always show the current author in the author dropdown when editing a post
- Fixes for attachment taxonomies
- Fix node removal for the admin bar
- Fix the custom post type show_in_menu argument
- Various fixes for right-to-left languages
- and a few dozen more changes
New in version 3.0.4 (December 30th, 2010)
- A very important update to apply to your sites as soon as possible because it fixes a core security bug in our HTML sanitation library, called KSES. The release is rated as “critical.”
New in version 3.0.3 (December 9th, 2010)
- Fixes issues in the remote publishing interface, which under certain circumstances allowed Author- and Contributor-level users to improperly edit, publish, or delete posts.
- These issues only affect sites that have remote publishing enabled.
- Remote publishing is disabled by default, but you may have enabled it to use a remote publishing client such as one of the WordPress mobile apps. You can check these settings on the “Settings → Writing” screen.
New in version 3.0.2 (December 1st, 2010)
- Fixes a moderate security issue that could allow a malicious Author-level user to gain further access to the site, addresses a handful of bugs, and provides some additional security enhancements.
New in version 3.0.1 (July 30th, 2010)
- Fixed 55 tickets total. A break down of ticket status by component can be found in Trac.
- Added unregister_nav_menu(), for child themes.
New in version 3.0 (June 18th, 2010)
- Major new features in this release include a sexy new default theme called Twenty Ten. Theme developers have new APIs that allow them to easily implement custom backgrounds, headers, shortlinks, menus (no more file editing), post types, and taxonomies. (Twenty Ten theme shows all of that off.)
- Developers and network admins will appreciate the long-awaited merge of MU and WordPress, creating the new multi-site functionality which makes it possible to run one blog or ten million from the same installation.
- As a user, you will love the new lighter interface, the contextual help on every screen, the 1,217 bug fixes and feature enhancements, bulk updates so you can upgrade 15 plugins at once with a single click.
New in version 3.0 RC 1 (May 28th, 2010)
- Custom menus are finished!
- Multi-site is all set.
- The look of the WordPress admin has been lightened up a little bit, so you can focus more on your content.
- There are a ton of changes, so plugin authors, please test your plugins now, so that if there is a compatibility issue, we can figure it out before the final release.
- Plugin and theme *users* are also encouraged to test things out. If you find problems, let your plugin/theme authors know so they can figure out the cause.
New in version 3.0 Beta 1 (April 6th, 2010)
- The custom menus system (Appearance > Menus) is not quite finished. In Beta 2, the layout will be different and a bunch of the functionality will be improved, but we didn’t want to hold things up for this one screen. You can play with making custom menus, and report bugs if you find them, but this is not how the final screen will look/work, so don’t get attached to it.
- The merge! Yes, WordPress and WordPress MU have merged. This does not mean that you can suddenly start adding a bunch of new blogs from within your regular WordPress Dashboard. If you’re interested in testing the Super Admin stuff associated with multiple sites, you’ll need some simple directions to get started.
- Fiddling with a few small things in the UI, as we were focused on getting the more function-oriented code finished first. For example, we’re getting a new icon for the Super Admin section.
- New default theme, Twenty Ten, including the custom background and header options.
- Custom Post Type functionality has been beefed up. It’s really easy to add new types, so do that and see how it looks!
- WordPress MU users should test the multiple sites functionality to make sure nothing broke during the merge.
New in version 2.9.2 (February 15th, 2010)
- There is a problem where logged in users can peek at trashed posts belonging to other authors. If you have untrusted users signed up on your blog and sensitive posts in the trash, you should upgrade to 2.9.2.
New in version 2.9.1 (January 5th, 2010)
- Addresses a handful of minor issues as well as a rather annoying problem where scheduled posts and pingbacks are not processed correctly due to incompatibilities with some hosts.
New in version 2.9.1 RC 1 (December 30th, 2009)
- Contains a few more fixes, bringing the number of fixed tickets up to 23.
New in version 2.9.1 Beta 1 (December 28th, 2009)
- The recent 2.9 release triggered a bug in certain versions of PHP’s curl extension. With these versions of curl, scheduled posts and pingbacks are not processed correctly. This version fixes this problem as well as a handful of other.
New in version 2.9 (December 19th, 2009)
- The coolest new stuff from a user point of view is:
- Global undo/”trash” feature, which means that if you accidentally delete a post or comment you can bring it back from the grave (i.e., the Trash). This also eliminates those annoying “are you sure” messages we used to have on every delete.
- Built-in image editor allows you to crop, edit, rotate, flip, and scale your images to show them who’s boss. This is the first wave of our many planned media-handling improvements.
- Batch plugin update and compatibility checking, which means you can update 10 plugins at once, versus having to do multiple clicks for each one, and we’re using the new compatibility data from the plugins directory to give you a better idea of whether your plugins are compatible with new releases of WordPress. This should take the fear and hassle out of upgrading.
- Easier video embeds that allow you to just paste a URL on its own line and have it magically turn it into the proper embed code, with Oembed support for YouTube, Daily Motion, Blip.tv, Flickr, Hulu, Viddler, Qik, Revision3, Scribd, Google Video, Photobucket, PollDaddy, and WordPress.tv (and more in the next release).
- 2.9 provides the smoothest ride yet because of a number of improvements under the hood and more subtle improvements you’ll begin to appreciate once you’ve been around the block a few times. Here’s just a sampling:
- We now have rel=canonical support for better SEO.
- There is automatic database optimization support, which you can enable in your wp-config.php file by adding define('WP_ALLOW_REPAIR', true);.
- Themes can register “post thumbnails” which allow them to attach an image to the post, especially useful for magazine-style themes.
- A new commentmeta table that allows arbitrary key/value pairs to be attached to comments, just like posts, so you can now expand greatly what you can do in the comment framework.
- Custom post types have been upgraded with better API support so you can juggle more types than just post, page, and attachment. (More of this planned for 3.0.)
- You can set custom theme directories, so a plugin can register a theme to be bundled with it or you can have multiple shared theme directories on your server.
- We’ve upgraded TinyMCE WYSIWYG editing and Simplepie.
- Sidebars can now have descriptions so it’s more obvious what and where they do what they do.
- Specify category templates not just by ID, like before, but by slug, which will make it easier for theme developers to do custom things with categories — like post types!
- Registration and profiles are now extensible to allow you to collect things more easily, like a user’s Twitter account or any other fields you can imagine.
- The XML-RPC API has been extended to allow changing the user registration option. We fixed some Atom API attachment issues.
- Create custom galleries with the new include and exclude attributes that allow you to pull attachments from any post, not just the current one.
- When you’re editing files in the theme and plugin editors it remembers your location and takes you back to that line after you save. (Thank goodness!!!)
- The Press This bookmarklet has been improved and is faster than ever; give it a try for on-the-fly blogging from wherever you are on the internet.
- Custom taxonomies are now included in the WXR export file and imported correctly.
- Better hooks and filters for excerpts, smilies, HTTP requests, user profiles, author links, taxonomies, SSL support, tag clouds, query_posts and WP_Query
New in version 2.8.6 (November 18th, 2009)
- Fixes two security problems that can be exploited by registered, logged in users who have posting privileges. If you have untrusted authors on your blog, upgrading to 2.8.6 is recommended.
- The first problem is an XSS vulnerability in Press This. The second problem is an issue with sanitizing uploaded file names that can be exploited in certain Apache configurations.
New in version 2.8.5 (October 21st, 2009)
- A fix for the Trackback Denial-of-Service attack that is currently being seen.
- Removal of areas within the code where php code in variables was evaluated.
- Switched the file upload functionality to be whitelisted for all users including Admins.
- Retiring of the two importers of Tag data from old plugins.
New in version 2.8.4 (August 13th, 2009)
- Yesterday a vulnerability was discovered: a specially crafted URL could be requested that would allow an attacker to bypass a security check to verify a user requested a password reset. As a result, the first account without a key in the database (usually the admin account) would have its password reset and a new password would be emailed to the account owner. This doesn’t allow remote access, but it is very annoying.
- We fixed this problem last night and have been testing the fixes and looking for other problems since then.
New in version 2.8.2 (July 21st, 2009)
- WordPress 2.8.2 fixes an XSS vulnerability.
- Comment author URLs were not fully sanitized when displayed in the admin.

- New Widgets API:
- WP_Widget is a class that abstracts away much of the complexity involved in writing a widget, especially multi-widgets.
- Basically, you extend WP_Widget with your own class that provides a constructor and three methods -- widget(), form(), and update().
- widget() - outputs the actual content of the widget.
- update() - processes options to be saved.
- form() - outputs the options form.
- A widget is registered by passing the name of the widget class to register_widget().
- All widgets written with WP_Widget are multiple instance capable.
- Options for old single-instance widgets ported to WP_Widget will be upgraded to the new multi-option storage format, which is simply a multi-dimensional array keyed by instance ID.
- Options for widgets using the old multi-instance pattern should work as is.
- If your widget has custom option storage needs, you can provide your own get_settings() and save_settings() methods.
- The WP_Widget source can be viewed here (read the phpdoc for moreinfo on usage): http://core.trac.wordpress.org/browser/trunk/wp-includes/widgets.php
- You can see examples of how to use it here: http://core.trac.wordpress.org/browser/trunk/wp-includes/default-widgets.php
- If you author any widgets, try porting them to WP_Widget and give your feedback on what can be improved an Trac Ticket 8441.
- Props to the MultiWidget class, on which WP_Widget is based: http://blog.firetree.net/2008/11/30/wordpress-multi-widget/

- Menu reordering via plugin:
- Example plugin demonstrates menus with Dashboard, Posts, and Comments in the first menu group. The remaining menus follow in their usual order.
- When filtering the order array, any menus that are not mentioned in the array will be sorted after ones that are mentioned.
- Unmentioned menus are sorted in their usual order, relative to other unmentioned menus.
