Unity 5.3.0 Beta

Known Issues

• IAP crashes on Android and Windows Store. Fixes expected for beta 3.
• MSE: Renaming a scene in the ProjectView does not update the Hierarchy View and maybe break your scene
• MSE: Deleting a scene in the ProjectView does not update the Hierarchy View and trying to save the scene again throws exceptions, data will be lost
• MSE: Íf the scene was unloaded but still part of the hierarchy trying to load it will throw exceptions
• MSE: Unloading a dirty scene does not ask for confirmation and data is lost
• MSE: When moving a GameObject from one scene to the root of another the destination scene is not marked dirty
• MSE: Under some circumstances not all scenes are saved when closing the editor. Make sure to do CTRL-S before closing the editor.
• MSE: Multi-scene baking for NavMesh and Lightmaps are still under development and will not be supported in this build
• MSE: Handling game managers for multiple scenes are under development, so playing multiple scenes in the Editor will throw errors in console related to duplicate game managers.

Feature

• Graphics: RenderDoc graphics debugger integrated with Unity Editor
• JsonUtility:
  • API is now marked threadsafe, and can be called from background threads
  • FromJson/FromJsonOverwrite now accept a TextAsset as input
• Unity IAP. Accessible via the cloud services window
• Windows Store: Added support for IL2CPP scripting backend

Improvement

• Asset Loading: Serialisation errors that produce "serialisation layout mismatch" errors will now attempt to include the name of the root type being serialised when the error was encountered.
• Editor: Expanding/collapsing TreeViews are now animated in the Editor
• Graphics: More detailed breakdown of forward rendering pipeline in Profiler.
• Input: Added Input.backButtonLeavesApp, usable on Windows Store Apps/Windows Phone 8.1 and Android, see docs for more info
• MonoDevelop: Added missing documentation tool-tips for methods with optional/default arguments. Removed mark-up from documentation tool-tips.
• OpenGL: Fixed threaded rendering on Windows. It was previously disabled as a workaround.
• Scripting: Added Matrix4x4.determinant property.
• WebGL: Compress player's data using LZ4

Fixes

• [Editor] Fix item names with shortcut chars (&%^#_) display wrong in menus
• [Editor] Fix Shift-Delete in rename box delete asset in scene.
• [Editor] Fixed a case of new lines in labels when the display name comes from an array of strings.
• [Editor] Use the correct image for Dark skin's horizontal scrollbar left button

• [IMGUI] Move the gamma assert to the Repaint phase.
• [IMGUI] Take font size in account even for null font when estimating content text size
• Fixed issue where objects lit by light probes appear brighter than static objects with same material in gamma mode. See upgrade guide for details.
• Frame Debugger: Fixed shader blend/depth/raster state settings sometimes not displayed correctly.
• Mecanim: Fixed Animator.GetParameter throwing exceptions
• Mecanim: Fixed AvatarTool's unfolding of Avatar body part when selecting from UI
• Mecanim: Fixed bad 1st frame when enabling Animator
• Mecanim: Fixed crash when calling Update() from OnStateEnter
• Mecanim: Fixed crash when modidying in Playmode an AnimatorController used in Playable
• Mecanim: Fixed deletion of body part using delete/backspace in the AvatarTool
• Mecanim: Fixed issues with Animator view synchronization:
• Mecanim: Fixed parameters not being evaluated when AnimatorController used in Playable
• MonoDevelop: Fixed Mono.Debugger.Soft.ObjectCollectedException thrown when setting breakpoint
• OSX: Fixed huge memory leaks when using OpenGL core in the editor
• OSX: Fixed Input.GetKey and Input.inputString not working
• Particle system 3D rotation fix, when checking and unchecking option
• Particle system crash fixes
• Particle system custom pivot point fixes
• Particle system LateUpdate fix
• Particle system scaling fixes
• Scripting: 'Editor' folders inside 'Plugins', 'Standard Assets' and 'Pro Standard Assets' no longer need to be at the root of those directories.
• Scripting: Fixed crash in some scenarios when project has missing assembly references
• Scripting: LayerMask.GetMask() no longer ignores the Default layer.
• Shaders: Upgraded obsolete 'alpha:blend' to 'alpha:fade' in builtin shaders
• WebGL: Fix an issue which could cause various stripping-related crashes as a consequence
• WebGL: Fix doppler effect being used on audio sources with spatial blend set to 2D
• WebGL: Fix unnecessary warnings about rendering to mipmaps
• Windows Store Apps: make Input.gyro available if either OrientationSensor or Gyrometer is available
• Windows Store: building project with IL2CPP scripting backend no longer fails.

The following are changes and fixes to 5.3 features and regressions...

Improvement

• Editor: Sticky scene header for multi scene Hierarchy (makes it clear which scene GameObjects belong to which when the normal header has scrolled out of view)

Fixes

• Editor: Multi scene editing: Support dragging GameObjects upon a scene header in the Hierarchy Window
• Frame Debugger: Correctly switch between local and remote frame debugger.
• Frame Debugger: Improved display & UI of shader properties.
• IL2CPP: Allow default parameter values for nullable types to be converted to C++ correctly.
• IL2CPP: Correct a crash in the il2cpp::icalls::mscorlib::System::Reflection::MonoMethod::get_base_definition method.
• IL2CPP: Correct method collection in editor to preserve defining class rather than invoked class in some cases.
• IL2CPP: Correct the generated C++ code when MonoPInvokeCallback is used to specify a type which has marshaling directives. The marshaling directives from that type will be used, and a compile error in the generated C++ code will no longer occur.
• IL2CPP: Generate correct C++ code when an extension method as a constrained generic type which is another generic type defined in a different assembly.
• IL2CPP: Prevent an ArgumentOutOfRangeException exception from occurring in Socket.Select when using the NetMQ library
• iOS/IL2CPP: Prevent a crash that occurs when using Unity Ads and GameCenter together.
• JsonUtility: JsonUtility no longer supports non-user-defined UnityEngine.Object types. Use UnityEditor.EditorJsonUtility for them now.
• JsonUtility: JsonUtility.FromJson() no longer supports creating ScriptableObject instances. Only plain .NET classes and structs are supported now.
• WebGL: Fix "Could not produce class with ID XY" errors in console.
