想做遊戲但不知從哪開始，Unity能幫你什麼

What's new in this version:

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.

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.

Known Issues
- Scene view picking in linear color space does not work for DX11 in 2x MSAA (quality: fantastic). The workaround is to set quality to less than "fantastic". This issue will be fixed in a future patch release.
