For more information about the previous main release, see the [Unity 4.6 Release Notes](https://unity.com/unity/whats-new/unity-4.6).

## Release notes

### Features

- Support for iOS 64-bit builds using il2cpp.

### Changes

- The Flash build target is no longer supported from this release onwards.

### Improvements

- Audio: Added WWW.GetAudioClipCompressed. Allows AudioClips obtained via WWW class to be loaded into memory compressed, similar to "Compressed in Memory" import option.
- Graphics: Added MaterialPropertyBlock.Set\*() methods to overwrite existing values in a MaterialPropertyBlock instead of adding duplicates.
- iOS: Add basic launch screen support.
- iOS: Expose “set pause” as ObjC API.
- Linux: Added more font fallbacks for Latin and CJK.
- Oculus GearVR: Enabled low latency audio support.
- Oculus Plugin: Future Oculus Plugin releases will no longer require Direct\_To\_Rift.exe
- Oculus: Added VR friendly splash screen for Unity Free.
- Scene View: DrawGizmo attribute now reports errors when used incorrectly, and has better documentation.
- Standalone: Screen.dpi implemented for OSX and Windows standalone platforms.
- UI: Change Text.m\_Text to protected and Text.text to virtual. In this way users can have control over the text contents when extending Text.
- UI: Expose EventSystem.firstSelected to API.
- WebPlayer UnityObject: It is now possible to identify the webplayer runtime version before loading content. This makes it possible to load different content based on the runtime version already installed.
