Unity Editor Windows (X86-64)
New to Unity? Get started
- Core: Added support for loading serialized files stored with versions >= 5.5.0a4.
- DX11: Improved texture upload performance for compressed, floating point and RGBA32 formats (also in 5.3.6p3) (812350).
- Graphics: GPU Instancing - it is no longer an error to use instanced shaders on renderers that don't support instancing (SkinnedMeshRenderer, SpriteRenderer, etc.).
- Graphics: GPU Instancing - for statically batched MeshRenderers, using an instanced shader now will not break static batching. If you want renderers to be instancing batched, please consider disable static batching flag (816786).
- Linux: Removed 16GB total memory limit.
- Networking: Projects using UnityWebRequest from UnityEngine.Experimental.Networking should now be auto-upgraded to use its new location in UnityEngine.Networking.
- VR: Mac version of the editor can now add OpenVR as a VR platform when targeting the Windows player.
- VR: Stereo View and Projection Matrices can be set individually through scripting API.
- VR: Updated the following Image Effects from the Standard Assets to work with Single-Pass Stereo: Ambient Obscurance, Camera Motion Blur. (811571)
- VR: Upgraded SDKs - Oculus to 1.7, GearVR to 1.7.1, OpenVR to 1.0.2.
- Windows Store: Windows Extension SDK references will now be automatically added to Assembly-CSharp projects.
Unity 5.4.1 also includes relevant fixes from 5.3.6 patch releases.

- Animation: Fixed an issue where an assert that couldn't be acted upon was popping in the AvatarMask inspector. (813105)
- Collab: Fixed a crash when opening a cloud project named with numbers if you already have a project named the same in your folder. (763383)
- DX11: Fixed editor spewing out "Failed to query D3D11 context for ID3DUserDefinedAnnotation interface" error message when run on Windows 7 machine without Windows updates installed. (819707)
- Editor: Fixed a bug that launching Editor window will exit after signed on windows. (816567)

- GI: Multi-scene editor. Fixed the lightmap indices not updating for additively loaded scenes in the Editor. (745588)
- Graphics: Fixed a crash when running with Graphics Jobs caused by one thread unloading mesh data whilst another thread is using the data.
- Graphics: Fixed ForwardAdd pass z-fighting issue when the object is rendered with GPU instancing, for example when you have multiple lights (819088).
- Surface shaders are automatically updated to apply the fix.
- For custom vert/frag shaders, instead of using the macro "UNITY_USE_CONCATENATED_MATRICES", now please use the new "#pragma force_concat_matrix" directive in the ForwardAdd pass.
- Graphics: Fixed image effects being rendered twice when the camera is instantiated from prefab or copying another camera. This issue was in player builds only. (814402, 811236)
