BUILT-IN NODES, TYPES, AND INPUT EDITORS:
Avoided doing unnecessary work in the Resize Image nodes when the image is already the desired size. (Thanks, @.lov., for suggesting this.)
When sending OSC using the Make OSC IP Output node, added support for entering broadcast IP addresses into that node's input ports. Now, when you use that node, if you enter a unicast IP address, it unicasts, and if you enter a broadcast IP address, it broadcasts (instead of merely unicasting to this host's IP address within the specified broadcast range). (Thanks, @jens, for suggesting this.)
Fixed issue when broadcasting OSC messages using Make OSC Output where it would broadcast only to the default network interface (which on some system configurations is the loopback interface, defeating the purpose of broadcasting). (Thanks, @jens, for reporting this issue.)
Improved performance of the Decode Movie Image node when decoding sequential frames. (Thanks, @alcomposer, for reporting this issue.)
Fixed the Build List node's occasional failure to fire Build Item events when the desired size changes faster than the time it takes to build the list. (Thanks, @Magneson, for reporting this issue.)
Fixed the Build List and Process List nodes' issue where they stop firing events during livecoding if the Build/Process Item port's event doesn't make it back to the Built/Processed Item port. (Thanks, @Alastair, for reporting this issue.)
Improved performance of the Split Text and Split Text Stream nodes when working with large datasets. (Thanks, @jens, for reporting this issue.)

Added more 3D/4D Point → Real type converters. (Thanks, @Bodysoulspirit, for requesting this.)
Fixed issue where Blend Colors would sometimes output colors with alpha greater than 1. (Thanks, @jersmi, for reporting this issue.)
Fixed issue where Make Linear/Radial Gradient Image/Layer would wrap out-of-range colors instead of clamping them. (Thanks, @jersmi, for reporting this issue.)
Fixed memory leak in Detect Audio Beats. (Thanks, @Magneson, for reporting this issue.)
In Mesh port popovers, added chart showing which vertex attributes were provided. (Thanks, @kozistan, for suggesting this.)
Improved Fetch Image's JPEG loading performance by replacing libjpeg with libjpeg-turbo (which implements SIMD optimizations).
Added "Replace Opacity" port to Blend Images to specify how the foreground image's opacity should be combined with the background image's opacity (Photoshop vs. GIMP).
Fixed issues in some Blend Images blend modes where alpha handling was inconsistent.

Switched bundling FreeImage and Open Asset Import from static libraries to dynamic, to improve compiling performance.
Reduced energy consumed when maintaining the texture and IOSurface pools, and when communicating between Vuo Editor and compositions. This should also reduce the occurrence of process caught causing excessive wakeups console messages.
Slightly reduced the amount of time it takes Vuo to build its cache the first time it's launched.
Fixed occasional hangs and crashes when livecoding with a composition containing subcomposition nodes, or when rapidly adding generic nodes.

Added pointer content summaries (visible with vuo-debug) when reporting calls for unregistered pointers (to help you track down the miscreant pointer).
Updated VuoCompiler::compileComposition() to throw an exception if the composition file is unreadable. Updated examples to demonstrate catching that exception.
Updated VuoColor documentation to clarify that it does not expect or provide premultiplied RGB values (unlike VuoImage).
Changed VuoGlTexturePool_use() to return 0 when texture allocation fails, instead of returning a valid texture name and leaving an error on the OpenGL context (or possibly crashing due to GPU driver issues).

VUO COMPILER AND RUNTIME:
Added the ability to turn a composition into a reusable node class (subcomposition) that can be used inside of other compositions. (Thanks to the many people who have advocated for this feature, including @mnstri for making a feature request and @George_Toledo for suggesting a feasible route to get basic subcompositions into this Vuo release.)
Sped up compiling of larger compositions.
Sped up compiling the first composition after installing a new node class. Third-party node classes are now cached separately from built-in node classes.
Improved performance of running compositions (memory management, AppKit event loop, exclusive locks on nodes).
Improved performance when running exported apps by eliminating communication that would normally go from the composition to the runner.
Reduced the amount of events dropped by compositions, especially in situations where a slower-firing trigger would drop all of its events because it was competing with a fast-firing trigger.
Fixed the 1-second wait when stopping a composition. (Thanks to @cwright for reporting this bug!)
Fixed memory leaks of data fired from trigger ports during live-coding reloads.
SDK:
Composition runner API:
Added an option (enabled by default) to exit all running compositions if the runner process dies. (Thanks to @.lov. for requesting this feature!)
Enabled a port's menu items (for enum types) to be accessed from VuoRunner. Added a "menuItems" key to the return value of VuoRunner::Port::getDetails(). Replaced -[VuoRunnerCocoa menuItemsForType:] with a "menuItems" key in the return value of -[VuoRunnerCocoa detailsForPort]. (Thanks to @lumenav for suggesting this feature!)
Improved performance of VuoRunnerCocoa, VuoImageFilter, and VuoImageGenerator methods that get a composition's image output as a GL texture. (Thanks to @.lov. for suggesting specific improvements!)
Added VuoRunnerCocoa, VuoImageFilter, and VuoImageGenerator methods that get a composition's image output and let the caller provide the GL texture in which it will be placed. (Thanks to @.lov. for suggesting this!)
Disabled, by default, most types of telemetry from the composition to the runner to improve performance. Added "subscribe" functions (e.g. subscribeToInputPortTelemetry()) to VuoRunner for enabling specific types of telemetry.
Fixed a crash when running a Vuo composition that displays a window within a host app that has its own NSApplication. The Vuo composition no longer implements its own NSApplication subclass.
Fixed a bug where the host app's menu bar would not be restored when a Vuo composition window resigned main status.
Node and type API:
Gave shaders the ability to capture what's been rendered so far using the renderBuffer uniform.
Added standard comparison functions _isEqual and _isLessThan to applicable types.
Added functions VuoLog_backtrace and VuoHeap_addTrace to help with debugging.
Command-line utilities:
Fixed bug that meant that the vuo-export command-line utility didn't copy the composition's resources if run from a different folder than the composition
Avoided printing the "No Vuo license was found on this system" warning multiple times in vuo-export movie.
