Whether on an iPhone or an iPod Touch, you will be able to dazzle your audience with the finest content available in the App Store. 2D or 3D, touch or tilt — if you can think it, you will be able to build it.

Player Size and Speed Improvements
Texture memory, Mono runtime and uncompressed audio runtime size have been reduced by up to 50%. We also improved the optimized script call optimization. This makes your games take less memory and run faster, while still looking and playing state of the art.

Portrait and Landscape Splash Screens
New and improved splash screens that you can choose from! Five splash screens are included in every built Xcode project (3 portait, 2 landscape). Just choose the one you want to use and rename it “Default.jpg”.

Additional Features, improvements, and changes
New Features and Improvements
Reduced memory footprint for uncompressed audio by 50%
“Memory usage for textures reduced by 50%. Texture memory is now freed once it has been submitted to OpenGLES on the device. The “Enable Get/SetPixels” flag in the Texture Import Settings lets you disable this feature on a per texture basis in order to access the texture data from a script using GetPixel etc.
Improved iPhone script call optimization
Removed unused parts of Mono runtime
Reduced memory overhead while reading data from disk and slightly improved load times.
Support for several predefined splash-screens (portrait/landscape) for Indie version. Just rename one of the splash-screens in the output directory to Default.png
Exported audio session activation/deactivation functions to AppController.mm
Added Scripting Reference code examples for iPhone specific APIs
