  • Terrain: Improved tree culling performance.
  • Windows Phone / Store: Slightly improved performance in master builds.


  • 2D: Fixed sprite importing regression which caused sprite references to be lost on texture rename.
  • Android: Fixed application hanging and crashing when trying to close the IME with the back button.

  • Android: Fixed mouse input for interacting with standard GUI.
  • Asset Import: Fixed crash when plugin DLL calls AssetDatabase.Refresh in type initializer.
  • Editor & Webplayer: Fixed crash when loading some meshes imported with Unity 3.5.
  • Editor: Fixed "ArgumentException: Invalid path" error that might occur with some custom windows.
  • Editor: Fixed an issue whereby text went out of the TextArea in custom editor when return was pressed or multi line text was pasted.

  • Graphics: Fixed skinned meshes sometimes not rendering in player builds when Read/Write Enabled import option is disabled.
  • Graphics: Fixed stencil modes only affecting front facing geometry when shader has Cull Off.
  • Graphics: Fixed textures in material property blocks (e.g. sprites) sometimes messing up other textures in the material on OpenGL.
  • Graphics: Fixed "allocation 0x00000000 already registered" error messages.
  • Graphics: Work around crash when trying to read invalid shader properties.
  • IMGUI: OnMouseExit not called when mouse is moved from a collider to IMGUI element that is occluding it.

  • OpenGL ES2: Fixed shader depth state handling.
  • Physics 2D: 2D colliders marked as triggers now don't affect center of mass or inertia calculations.
  • Physics 2D: Allow the change of Z transform position only, without disturbing Rigidbody2D interpolation.
  • Physics 2D: Rigidbody2D without colliders now has default inertia and center of gravity.
  • Physics 2D: Stop memory leak when assigning vertex array to PolygonCollider2D.points with invalid geometry.
