  • iOS: Display the number of finished files in AOT cross-compile progress bar.
  • Linux: Implemented screen-fullscreen command line option.
  • OSX: Implemented show-screen-selector command-line option.
  • Physics: Show inspector warning when a 2D collider removes generated collision shape(s) because they fail verification. This supplements the existing warning when no collision shapes are present.
  • Shaders: Improved performance of importing complex surface shaders (with many multi_compile directives).
  • Shaders: Improved performance of shader compilation for OpenGL platforms.


  • Android: Android TV - Fixed uses-feature attribute in manifest that could require touchscreen.
  • Android: Fixed delay when resuming game from paused state.
  • Android: Fixed flickering screen on resume.
  • Android: Added missing implementation of UnityMemoryBarrier()
  • Android: Fixed crash on application resume on Adreno devices with Android 4.1.1 or 4.1.2.
  • Android: Preventing black frame to be displayed when on-screen keyboard appears/disappears.
  • Android: Export now works for projects that use UnityPlayerActivity or UnityPlayerProxyActivity.
  • Asset Import: Recompile scripts synchronously when the -buildTarget parameter is used.
  • Core: Fixed the "Failed to initialize unity graphics" error when using the -no-graphics flag in OS X
  • Direct3D 11: Unity will now correctly fall back to no MSAA depth textures if the GPU does not support ones with MSAA.
  • Documentation: Fixed rendering for richText.
  • Editor: Fixed word wrapping in the detail area of the console.
  • Editor: Handle an intermittent failure in CoCreateInstance during the Visual Studio launch process.
  • Editor: Open a script in the correct version of Visual Studio when the script is already open in a different version.
  • Editor: Fixed selected wireframe not rendered if object's shader has GrabPass as the first pass.
  • Editor: Use External Editor argument expansion in undocumented API.
  • Editor: Fixed an issue whereby dragging a prefab into hierarchy from project view was not selected automatically.
  • Editor: Don't pass out incorrect PropertyHandler on first call to GetHandler.
  • Flash : Empty project no longer has (harmless) errors in the log.
  • OpenGL ES 2: Fixed issues with native plugin called in OnPreRender .
  • Graphics: Send kGfxDeviceEventInitialize to native plugins if renderer changes.
  • Graphics: Fixed light culling with custom projection matrix.
  • Image Effects: Fixed Image filters targeting a render texture when a camera doesn't clear the color buffer.
  • Image Effects: Fixed Fast Bloom rendering upside down on Direct3D when anti-aliasing was used (reimport Image Effects package to get the fix).
  • iOS: Adaptively increase AOT build timeout to fix builds on large projects.
  • iOS: Do not run excessive number of mono AOT compiler instances.
  • iOS: Fixed Xcode 6 GM build & run support.
  • iOS: Fixed Xcode 6 GM Simulator support.
  • License: Give permissions to Users group on Windows to modify/write the license .ulf file, after Unity was activated by an administrator.
  • Linux: When using "Default is fullscreen" and "Default is native resolution" on a multidisplay system, store the resolution pref from the actual window size instead of the full desktop resolution.
  • Manual: Update documentation for player command line arguments.
  • Mecanim: Fixed trigger parameter consumption when used by multiple layers.
  • OSX: Now GameKit is loaded dynamically, it should help with Mac App Store submissions for games, which are not using Game Center.
  • OSX: Application.persistentDataPath changed from ~/Library/Caches/ to ~/Library/Application Support/
  • Physics: 'OnMouseDown' and 'OnMouseUp' callbacks for 3D physics now don't take priority over 2D physics, they can run simultaneously.
  • Physics: 'OnMouseDown' and 'OnMouseUp' callbacks for both 2D and 3D colliders now correctly use camera near/far plane distance.
  • Scripting: Properly validate class constraint on generics with reference type constraint.
  • Shaders: Fixed #include processing that are nested in #ifdef blocks in surface shaders.
  • Shaders: Fixed faceforward() for OpenGL platforms.
  • Shaders: VFACE pixel shader semantic translates more properly to OpenGL platforms now (values of -1 or 1, not 0 or 1 like before).
  • Substance: Fixed regression where valid runtime cache data would not be used and ProceduralTextures would be needlessly recomputed.
  • Substance: ProceduralTextures are no longer corrupted when switching color space in the editor.
  • Substance: ProceduralTextures are no longer corrupted when switching the masterTextureLimit in the editor.
  • Substance: Textures generated from a cloned ProceduralMaterial now have the proper alpha channel.

  • Windows Store Apps: C++ plugins are now correctly copied to output directory when using C++ project type.
  • Windows Store Apps: Unprocessed plugins are no longer included in Visual Studio pre-build event.
  • Windows Store Apps: Unity C# projects are referenced by project references instead of assembly references.
  • Windows Store Apps / Windows Phone: Fixed an issue which caused methods of WebHeaderCollection class throw exceptions
  • Windows Store Apps / Windows Phone 8.1: Fixed Screen.dpi to return physical screen DPI, instead of logical DPI.
  • Windows Store Apps / Windows Phone 8.1: Significantly reduces memory used by compressed audio.
