Release notes

Features

• WebPlayer: Added support for 64 bit Mac OS X browsers.

Improvements

• AssetBundles: Added additional information about WWW.LoadFromCacheOrDownload.
• Graphics: Improved performance when allocating memory for large numbers of temporary objects.
• Graphics: Optimized culling of lights in a mostly deferred scene with a few forward-rendered objects.
• Physics 2D: Added ‘Static Collider Shapes’ to profiler for 2D physics.
• Physics 2D: Renamed Physics2D.deleteStopsCallbacks to Physics.changeStopsCallbacks to better represent its purpose (old property is now obsolete).
• Serialization: Randomize fileIDs for objects in prefabs to lower the chance of merge conflicts.
• UI: Encapsulate children mesh bounds when calculating Root Bounds. Also cache the value so we don’t calculate every time we draw.
• UI: Performance optimizations. Optimized UI batching, text rendering and reduced amount of editor-only allocations.
• UI: Standalone input module now leaves keyboard selected object selected. Mouse and Keyboard input are now orthogonal. Clicking with the mouse will move selection to the clicked element.
• Windows Phone/Store Apps: Profiler shows managed memory usage.
• Windows Phone/Store Apps: Provide ArrayList.BinarySearch implementation.
• Windows Standalone: You can now embed windows standalone player into another application, simply pass -parentHWND and windows standalone application’s window will be created with specified parent. See Command line arguments documentation for more information.

Changes

• Documentation: Styling changed to match website design, switch links between Manual and Script Reference are working now.
