Sind Sie neu bei Unity? Erste Schritte
- iOS: Added UnityGetGLView function to AppController.mm that returns the view that unity uses

- Flash: Dictionary.ContainsValue now works.
- Flash: Smaller memory footprint in some cases
- Flash: Speedup in SWFPostProcessing

- Flash: Implementations of System.Random, System.IO.MemoryStream, DateTime.Today
- Flash: System.Exception.StackTrace property.
- Flash: more conversion errors include related source location now.
- Added Resources.UnloadAsset(Object asset) function. This is useful for unloading large individual assets if you know they are no longer used and you don't want to call Resources.UnloadUnusedAssets().
- Editor: Introduced [Callbacks.PostProcessBuild] script attribute. It will execute the attributed method after the player has been built.
- Editor: Introduced [Callbacks.PostProcessScene] script attribute. It will execute the attributed method when the current scene has been processed.
- Flash: Has build targets for different FlashPlayer version 11.0, 11.1 and 11.2. No Flash Player version specific implementations exposed yet, but setting 11.2 means using a faster code path; better performance.
- Flash: www.GetAudioClip() now works, only for non streaming mp3's.
- Flash: WWW support
- Flash: WWWForm Support
- Flash: Assetbundle support
- Android: Possible fix for random crashes in OpenGL ES driver on Galaxy Nexus ICS.
- Android: Touch problems related to ICS upgrades on some devices have been fixed.
- Android: Caching.CleanCache() was always returning false (without cleaning the cache).
- Android: Fixed Webcam texture initialization problem on ICS device.
- Editor: Catch more corner cases when detecting Visual Studio installations.
- Editor: Fixed out-of-memory crash when showing AudioClip's inspector while in play mode.

- Fixed WebPlayer crash when downloading an AssetBundle.
- Fixed a bug in mouse delta handling for non HID enabled mice.
- Fixed an out of memory crash on audio preview.
- Fixed race condition while hashing assets for the cache server.
- Fixed crash in Resources.Load if the resource being loaded referenced a non existing asset.
- Fixed out of memory crash when building a player with a lot of assets cross references between scenes.
- Fixed bug where SkinnedMeshRenderers marked as Occluders would result in bad occlusion. SkinnedMeshes can only be marked as Occludees now and the bounding volume of the skinned mesh is used during PVS Calculation.
- Fixed crash when reloading scripts after launching Unity with a compile error.
- Flash: Fixed integer division semantics.
- Flash: Fixed memory leak in native methods returning structs.
- Flash: Fixed crash on constructors passing fields as byref arguments.

- Flash: Fixed endianness error on byte.
- Flash: Fixed crashes on monobehaviour deserialization on asset bundles.
- Flash: Fixed particle system not being scriptable again.
- Flash: Fixed www.error being set to seemingly random strings, even if there was no eror.
- Flash: Fixed crashing on fatal errors on errors thrown in coroutines.
- Flash: Fixed fatal errors on www.texture access.
- Flash: Fixed flash preloader bar on black background.
- Flash: Fixed bug where array.CopyTo() fails if the destinationsize is larger than sourcesize.
- Flash: Fixed fields of type List crashing on Instantiate().
- Flash: Fixed serialization of List.
- Flash: Fixed multiple issues with SwfPostprocessor resulting in issues with swf not getting verified or causing stack under - or overflows.
- Flash: Many small actionscript conversion issues fixed.
- Flash: GuiTexture is rendering correctly again.
- Flash: Particles are rendering correctly again.

- Flash: Issues with coroutines throwing FlashPlayer verify and stack size errors fixed.
- Flash: EncodeToPNG now works.
- Flash: Support for c# packing of array data in types.
- Flash: Correct handling of numeric casts of infix expressions (ex: (int)(f * g)).
- Flash: Fix serialization of List
- Flash: Fix SwfPostprocessor; cases where player was throwing fatal error indicating that files are not available / verifier error on constants.

- Windows Player: Fixed occasional hang in multithreaded renderer when going in and out of fullscreen mode.
In Unity 3.4 realtime lights were not affecting static objects. In Unity 3.5 realtime lights always affect static and dynamic objects.
The result of this is that if you had previously setup your lighting to work around this bug, then you will now get worse performance as you will receive the lighting twice. It will also look different since your lights will be added twice to the scene.
The correct way to use these lights is to use a single auto directional light and remove the realtime only light.
If you wish to have different realtime lighting than static lighting, you should using light culling masks to affect only dynamic objects.
