# Unity 4.7.0

The Unity 4.7.0 release brings you few improvements and several fixes. Read the release notes below for details.

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

### Improvements

- Android: Added support for Marshmallow OS runtime permissions. Added possibility to disable permission dialog by adding activity metadata.
- iOS/IL2CPP: Now allow null checks, array bounds checks, and divide by zero checks to be selectively included or omitted from generated C++ code by using a C# attribute on type, method, or property definitions.
- iOS/IL2CPP: Enabled incremental build support using the "Append" option. Keep the generated code stable across additional, removal, and changes for string literals and non-generic types.
- iOS/IL2CPP: Added support for the MethodImplOptions.NoInlining option to prevent methods in the generated C++ code from being inlined.

### Changes

- Android: Disabled Audio Fast Path for GearVR.

- iOS/IL2CPP: Prevent a KeyNotFoundException exception from occurring during code conversion when a generic method is used with at least one generic argument that exceeds the maximum generic recursion depth (730233).
- iOS/IL2CPP: Prevent a memory leak that caused some GCHandles, including those used to reference MonoBehaviour instances, from being correctly reclaimed by the garbage collector (736167).
- iOS/IL2CPP: Prevent a NullReferenceException exception from occurring during the processing of the Preserve attribute which can obscure the actual cause of a problem (717997).
- iOS/IL2CPP: Prevent an intermittent hang with asynchronous sockets (718885).
