Graphics
Improvements
Major performance improvements in OpenGL ES 2.0 (iOS / Android):
Much improved performance of shaders that are compiled from Cg/HLSL (e.g. Diffuse for directional light is about 2x faster on iPhone 3Gs). Now fixed/half/float types in Cg map to lowp/mediump/highp precision in GLSL. Use lowest precision type in your shaders!
Improved GLSL shader optimizer.
Changed normal map compression approach for mobile platforms. It’s much faster now!
Fog mode can be changed in Render Settings (also from scripts): Linear, Exp, Exp2 (default).
Rendering performance optimizations (lower CPU overhead, less memory consumption).
Shadows:
Forward rendering path supports Point & Spot light shadows again, as well as multiple shadowing lights! Note that by default shaders do not have this enabled, use fullforwardshadows surface shader directive to enable the behavior.
Directional Light soft shadows blur width and fadeout speed can be adjusted in Inspector or via script.
Exposed Light.shadowBias to scripting.
Built-in shaders that perform Deferred Lighting, directional light shadow gathering in Deferred Lighting, and directional light shadow blurring can be overriden. Just drop your own shaders with the same names into the project.
Deferred light buffer can be accessed from from Image Effects or other shaders (_LightBuffer).
Surface Shader improvements:
support world-space normal as input (worldNormal).
fullforwardshadows directive to enable all shadows from any lights in forward rendering loop.
dualforward directive to enable dual lightmaps in Forward rendering.
decal:blend mode for shaders used on decal-like surfaces.
nolightmap directive to exclude lightmap support (makes shaders smaller).
noambient directive to not apply ambient nor SH lighting.
halfasview directive to compute normalized half-direction per-vertex, and pass that to the lighting function. Results in faster Specular-type shaders, however view direction won’t be entirely correct.
approxview directive to compute normalized view direction per-vertex instead of per-pixel. Results in faster Specular-type shaders, however view direction won’t be entirely correct when camera gets close to surface.
noforwardadd directive to skip generating forward additive pass. Will make a shader support one full directional light; all other lights will be per-vertex/SH.
Shaders: #pragma glsl_no_auto_normalization directive to not auto-normalize normals & tangents in OpenGL ES 2.0 shaders.
Shaders: Added TransformViewToProjection to do this properly on mobile devices with regard to orientation (on non-mobile it will be usual multiplication by diagonal terms of projection matrix).
Shaders: Added per vertex lit tree shaders previously used in the Bootcamp demo. To be used with Tree Creator trees and located in “Nature/Tree Creator Leaves Fast”.
Desktop GLSL shaders now allow OpenGL ES precision types to be used.
Added GL.GetGPUProjectionMatrix that returns actual projection matrix that will be used in shaders.
Added support for 16bit RenderTextures.
Scaled meshes are now only recreated if the scale has actually changed. This improves performance hiccups on same games.
Texture2D.GetPixel and friends work on RGBA32 textures (common case for uncompressed textures on mobile platforms) in addition to ARGB32 ones.
Texture2D.Apply and Texture2D.PackTextures now have additional parameter makeNoLongerReadable (default to false) that will mark Texture as not Readable, and free up system memory after uploading to GPU.
Fixes
Shaders: Bunch of fixes to Cg->GLSL shader translator:
Translates ‘half’ and ‘fixed’ matrix types properly (previously ‘half’ was translated to high precision, and ‘fixed’ was not supported).
Support lit() built-in function.
Fixes to swizzles on floats.
Support static qualifier.
Better handling of 2D matrix indexing, e.g. matrix[j].
Shaders: fixed mis-compilation of matrix constructors & matrix indexing when translating shaders to GLSL.
Shaders: fixed mis-compilation of modf() and fmod() when translating shaders to GLSL.
Shaders: Postprocess Direct3D pixel shaders that come close to 64 instruction limit to work around a crash on Intel GMA 950.
Shaders: Fix some bogus error messages when loading Direct3D shaders.
Surface Shaders: in case of syntax errors, proper line numbers are reported now… how cool is that? 😉
Surface Shaders: support #pragma multi_compile directives properly.
Lightmapper fixes:
Fixed UV layer creation for Beast. Fixes all the “Duplicate uv layer name” errors.
Fixed tiling and offset being ignored for _MainTex on objects using a non-white color.
Fixed an issue in Beast causing black areas surrounded by white outlines to sometimes appear in lightmaps.
Fixed lightmapping of objects with mirrored (odd-negative) scale.
Fixed the crash when lightmapping terrains where the Terrain script references a missing TerrainData asset.
Fixed an issue with Beast occasionally cancelling the bake process (especially on Mac OS X, but also causing poor performance on Win) when using a lot of memory.
Fixed the issue with 4096 size terrain lightmaps not baking on Mac OS X.
Fixed DXT5 alpha channel decompression to better match what GPUs are actually doing.
Fixed Texture2D.GetPixel on Alpha8 format returning 0.00392 in RGB channels instead of 1.0.
Fixed a bug in Cloth rendering that was mostly happening on Windows with Radeon GPUs.
Fixed custom projection matrices sometimes not working properly.

Fixed Texture2D.ReadPixels on Direct3D when reading into a portion of a texture.
Fixed Soft Occlusion Tree shaders sometimes rendering overbright on Windows with GeForce FX/6/7 GPUs.
Fixed lightmapped VertexLit shader applying fog in a wrong way on old GPUs with only 1 texture unit.
Texture2D.ReadPixels properly reads from Game View when non-full aspect ratio is used.
RenderTexture.GetTemporary now always returns a texture with bilinear filtering set (previously could return with something else when returning a texture from existing texture pool).
Fixed directional light shadows in case of weird projection matrices (e.g. Refractive Water).
Make WindZones be properly affected by Time Scale.
WindZones properly affect Tree Creator trees put into terrains now.
Fixed wrong Point/Spot light attenuation on Tree Creator leaves.
Graphics.Blit does not require using Cull Off in the shader now.
Shadows can be properly cast from particles now, if you use opaque or cutout shaders on them.
Fixed changing Flare color from script not always having effect.
Opaque objects are front-to-back sorted again for performance reasons. Looks like this got lost with all batching work in Unity 3.0.
Fixed dynamic batching issues with uniformly scaled objects and vertex lighting on Direct3D.
Fixed rendering of scenes containing objects with odd-negative scale in deferred when any of the lights was casting shadows.
Fixed Deferred Lighting not respecting camera’s Don’t Clear mode.
Fixed bogus error message when a shader with an empty name has no fallback.
Fixed half-texel offset error when generating tree creator texture atlas.
OpenGL ES 2.0: Fixed Fog with semitransparent fixed function shaders.

Improvements
Alpha-tested objects are drawn after fully opaque ones for performance reasons.
Implemented MSAA (Multisample anti-aliasing) support. You choose it in Quality Settings just like for other platforms.
Audio: Gapless looping of MP3s! Unity’s MP3 encoding is completely rewritten and silent frames and/or audible “pops” around the loop point is no more. Use the “Gapless loop” option in the Audio Importer to encode the MP3 for looping. Beware this stretches/resamples the sound which theoretically can affect quality.
Mobile devices now have their own quality settings (Project Settings->Quality->Default Mobile Quality).
Improved performance by using OES_vertex_array_object and EXT_discard_framebuffer extensions.
Added automated native plugin integration into Xcode project. All .m/.mm/.c/.cpp/.a files located in Assets/Plugins/iOS will be merged into Xcode project with every Unity project build.
Performance warning now shows up when deploying a project using anti-aliasing and/or more than 1 pixel light.
Use unnamed process-wide kernel semaphores instead of slower system-wide semaphores.

Decreased the install size to the Internal Storage flash memory (currently approx. 180KB, ie ~2% of 3.1).
Audio: Gapless looping of MP3s! Unity’s MP3 encoding is completely rewritten and silent frames and/or audible “pops” around the loop point is no more. Use the “Gapless loop” option in the Audio Importer to encode the MP3 for looping. Beware this stretches/resamples the sound which theoretically can affect quality.
First draft of typeless JNI integration from scripts (C#/JS) through AndroidJavaObject / AndroidJavaClass and AndroidJNI / AndroidJNIHelper.
Added UnitySendMessage on Java side to provide callback functionality to C# / JavaScript.
WWW now uses system URL class; https://, and also jar:, is now supported.
Added Application.persistentDataPath and Application.temporaryCachePath.
Added [i]PlayerSettings / Other Settings / Force SD-Card Permission.

Input.inputString now also works with hardware keyboard on the devices which have one.
Added editor preference for Android SDK location.
Now have their own quality settings (Project Settings->Quality->Default Mobile Quality).
Performance warning now shows up when deploying a project using anti-aliasing and/or more than 1 pixel light.
Fixes
Fixed the tablet accelerometer bug where portrait/landscape axis were swapped.
Fixed NullPointerException race-condition in FMOD when pausing the application.
Behaviour of ‘Compress Assets on Import’ turned off is now that no textures or assets will be reimported with their platform specific override settings right away. Thus allowing for fast switching between build targets. When a build is made, all assets are ensured to have the right format. (was done in earlier builds actually).
JDK lookup now fallbacks to use the PATH if registry key is not found / valid (Windows).
Fixed: No more duplicate entries in AndroidManifest.xml.
Fixed the clip rectangle of the soft input text box not being updated properly.
Added missing Mono machine.config specification file (needed for SQL access).

Fixed touch began events to always have zero Touch.deltaPos.
When tapping faster than once per frame, individual taps are no longer lost, they’re reported as taps with a separate finger ID and properly incremented tap count.
Touch.tapCount is no longer hardcoded as 1 and properly returns number of rapid taps in nearly same position.
Timestamps no longer lose data by squeezing 64-bit values through 32-bit parameters.
Audio
Improvements
FMOD 4.32.02 used across all platform/build targets.
Fallback on FMODs software mp3 decoder when Apple’s decoder (hw/soft) fails completely.
Better documentation for min-/max-distance properties.
.Play() with a delay now works on iPhone.
Streaming with WWW.audioClip now works with OggVorbis (PC/Mac/Web), MP3 (iOS/Android), WAVs (all platforms) and module files (all platforms).
Streaming with WWW.audioClip is much faster.
Stream audio from disc. Added “Stream from disc” option in the Audio Importer. Choose this to stream audio directly from disc instead of loading the entire clip into memory. This can decrease your application memory usage greatly.
Optimize the playback of compressed audio (on Android and iOS).
Fixes
AudioImporter inspector cleaned up and simplified.
Fix sounds starting when switching back to a paused editor on Windows.
Fix memory trash when encoding 8 bit wav files to MP3.

已知问题:
When autoconnect profiler is enabled the Editor can become unresponsive after selecting Build and run for Android.
Direct Modo file import issues:
Files can not be imported from modo 401, due to a problem in Modo batch mode.
UV coordinates for some meshes are not imported correctly, due to a problem in Modo Collada plugin.
Normals for some meshes are always exported as hard edges, due to a problem in Modo Collada plugin.
Unwrap: some implementation details were changed, so you may need to rebake your lightmaps, due to UV changes.
3dsMax reference meshes are not imported correctly (FBX plugins do no export any modifications added on top of the instance), because of the bug on Autodesk side. No changes on Unity side are needed, so it will be fixed as soon as Autodesk fixes FBX plugin for 3dsMax.
Materials on instance meshes are not imported correctly – they always share the same material. This happens due to structure of FBX files, so this can’t be fixed until Autodesk makes FBX structures more suitable for instanced meshes with different materials.
Audio: Seamlessly looping clips breaks when compressed for iPhone/Android.
When duplicating a dirty asset its preview in the Object Picker is incorrect until dirty again.
