Scaleform 4.6 provides new performance improvements such as AS3 debugger, improved garbage collection, Flash 10.1 compatibility and several bug fixes.

This release includes core performance improvements such as:

• Faster garbage collector.
• Flash 10.1 compatibility.
• Redesigned event system with the addition of new ActionScript methods such as flash.events.KeyboardEvent.updateAfterEvent, flash.events.MouseEvent.updateAfterEvent, to control the event flow.
• Ability to catch uncaught exceptions and report them (implemented classes flash.events.UncaughtErrorEvent, flash.events.UncaughtErrorEvents and properties flash.display.LoaderInfo.uncaughtErrorEvents and flash.display.Loader.uncaughtErrorEvents).
• Ability to control frame rate from ActionScript (implemented property flash.display.Stage.frameRate).
• Added new C++ method Scaleform::GFx::ASMovieRootBase::GetNeedToDraw, which lets you skip calling of draw methods after each event occurrence.
• Reimplemented class flash.system.ApplicationDomain. Added new method scaleform.gfx.SystemEx.getApplicationDomainClasses which returns a vector of class names belonging to an Application Domain.
• Reimplemented class flash.utils.Dictionary to a different implementation of the hash table.
• Improved performance of PlayList.

• GFxPlayer can be used to debug AS3 code with external tools as a drop in replacement for Adobe Flash Player. For more details, see Scaleform AS3 debugger.

• Scaleform uses FMOD Studio Low Level API for audio support.

• Integration packages are available for UE4.14.3 and UE4.15.

• Scaleform adds support for Vulkan API with faster performance and rendering optimizations. Currently, Vulkan is supported on Windows, Linux and Android.
• Scaleform now supports PS4 Neo.
• In addtion to ARM64, Scaleform now supports ARMv7. See Scaleform SDK for iOS and tvOS.

• Improved Windows 10 IME support.

• Scaleform is now available as ZIP files replacing the executable installers.
• Scaleform now uses an SPM script to build its libraries. The 3rd party libraries are also downloaded using the SPM.
• Use CMake to generate Scaleform projects and build the host platform. For more details, see SDK Installation.
• The configuration options (#defines) in the header file Inlcude/GFXConfig.h no longer exists and is now in CMake. The GFxConfig.h instead generates a configuration file for each supported platform with unique configuration options.
• Scaleform supports LZMA compression.

• GFxPlayer draws frame on each event
• Extremely inefficient implementation of ByteArray operations in AS3_GFxValueImpl.cpp
• GFX_AS_ENABLE_GC is redundant with AS3
• Make Application Domain work
• PS4: GetCurrentDateAndTime takes too long
• Update to libpng-1.5.27 for all platforms
• Massive warning spew when compiling with Android NDK 12b
• Assertion failure in AS3::ValueStack::PushBack
• Add missing assets for KinectInSWF sample
• Fix a crash on startup in Android, when compiled with –O3.
• TextFieldEx.setImageSubstitutions (AS3) does not work with GFx::Translator::OnBidirectionalText
• Fix issues with IME and LineBuffer, which could result in a crash
• getTextField would construct a TextField object only considering the first character's format in the given range
• Fix method DisplayObjectBase::Local3DToGlobal(). ViewMatrix3D can be in either twips or in pixels
• Fix method AvmDisplayObj::OnEventUnload() to clear AS3 property on parent object within all branches of code.
• Fix algorithm of calculation of bounds within DisplayObjectBase::GetBoundsIn3D()
• Add support for Windows XP within GFx_Socket_Win32.cpp
• Fix a bug with Loader::content
• Fix handling of Event.RENDER. Implemented method updateAfterEvent()
• Fix typo in SF_ThreadsStd11 module
• Fix PS4 content is not set to start-up by default from /app0
• Fix Segfault when launching MenuKit on PS4
• Display "drag'n'drop" message only on supported platforms
• Add specific media path to SoundEventFMOD initialization

• Reimplement AS3 class Dictionary.
• Store domain name with Application Domain. Added new file unloading mode.
• Improve performance of AS3::HashTable and AS3 Dictionary.
• Implement undocumented opcode finddef.
• Fix a bug with the method AbcBlock::MergeFromPredecessors(). A start node is always initialized.
• Fix AbcBlock::Coerce2Type() for a case when we need to coerce type on OpStack.
• Fix a bug with AbcBlock::PushNodeIF() that was deleting a node even if its result was used.
• Fix a bug with the method AbcBlock::ReductNotNot()
• Change implementation of the method AbcBlock::RemoveDeadBlockFromRPOList() to run garbage collection after removal of a block. This takes care of circular references among blocks

• MemoryManager returns inconsistent values on different platforms when allocation fails
• PrepareForReset/RestoreForReset on invalid platforms
• Fix an assert - Attempt to call GL function: glBindSampler, but it was NULL
• OPENGL uses more than twice the amount of memory than DX renderers
