Release notes

Features

  • iOS: iOS9 app slicing support.
  • iOS: iOS9 on demand resource support.

Improvements

  • Android: On some devices Screen.dpi returns more accurate values.
  • Editor: Added progress bar while decrypting downloaded Asset Store packages.
  • Graphics: Added overloads to CommandBuffer.SetRenderTarget() to allow specifying a target mip level and cubemap face.
  • Improved ETC1 based policy for grouping of sprites on an atlas.
  • iOS: Added frameworks new in iOS 8.0 to 9.0 to the plugin importer UI.
  • iOS: Added support for iPad launch screens
  • iOS: Exposed option in Player Settings to temporary disable Application Transport Security checks in iOS 9.0.
  • iOS: Now support access to iOS9 data assets within asset catalogs via virtual filesystem.
  • Networking: Added NetworkManager.UseExternalClient() function that allows the NetworkManager to use a client object created externally to the NetworkManager instead of using StartClient(). This was required to use custom NetworkConnection classes with connections made by the NetworkManager.
  • VR: Oculus: Upgraded to 0.7 dependencies.

Changes

  • iOS: Use launch screens as primary source for splash images.
  • VR: For Windows Oculus Development, the Oculus 0.7.0.0 runtime is required in order to run in VR mode. Future releases will also require this runtime going forward.
