FEATURES
特色
XboxOne: The default update granularity used by XDK’s makepkg tool has changed to File granularity rather than Chunk granularity. There is now a setting to control this:
XboxOne:使用XDK’s makepkg 工具的默认粒度修改为文件粒度而不是块粒度。现在有一个设置用来控制：
Player Settings > Xbox One > Microsoft Xbox One Package Settings > Update Granularity. This
Player Settings > Xbox One > Microsoft Xbox One Package Settings > Update Granularity.
property is set to File by default. Chunk is recommended only for games that have already been
released using the Chunk granularity, which was the default prior to this build.
这个属性默认设置为文件。块只呗推荐用在早就用快粒度发布的游戏，这是之前的默认构建方式。

IMPROVEMENTS
改进
Editor: Added Android 5.0 and 5.1 to “Minimum API Level” list.
编辑器：添加安卓5.0和5.1到“Minimum API Level”列表。
GI: Don’t add lights to Enlighten at runtime if they don’t contribute to GI (bounce intensity at 0).
GI：不要再运行时添加灯光到Enlighten如果他们对GI没有贡献（反射系数为零）。
GI: Made pig assert message human readable.
GI：整理臃肿的资源消息让人可读。
iOS: Enabled thumb instruction support for IL2CPP ARMv7 slice. Should improve ARMv7 slice code size by 10-20%.
iOS:为ARMv7版本启用支持IL2CPP的thumb指令。可以提高ARMv7版本的代码大小10~20%。
iOS/IL2CPP: Avoid generating NullReference checks on value types.
iOS/IL2CPP：避免在值类型上产生NullReference检查。
iOS/IL2CPP: Improve performance of finally blocks.
iOS/IL2CPP：提升最终模块的性能。
iOS/Metal: Better support for native rendering plugins when using Metal.
iOS/Metal：当使用Metal时更好的支持本地渲染插件。
Mecanim: Fix direct blendtree editor slow down when there is too much motion.
Mecanim：修复当拥有太多动作时直接导致blendtree编辑器变慢的问题。
Physics 2D: Added ‘AreaEffector2D.useGlobalAngle’ to allow the selection of whether the force-angle is global or local.
Physics 2D：添加’AreaEffector2D.useGlobalAngle’来允许是否选择使用的力度是全局还是本地的。
Physics 2D: Added ‘Effector2D.useColliderMask’ to allow the selection of whether the effector collider mask is used or the global collision matrix.
Physics 2D：添加’Effector2D.useColliderMask’来允许选择使用的effector碰撞蒙版使用全局的碰撞矩阵。
Physics 2D: Added ‘Rigidbody2D.IsTouching’ and ‘Rigidbody2D.IsTouchingLayers’ to complement the same on ‘Collider2D’ and ‘Physics2D’.
Physics 2D：添加 ‘Rigidbody2D.IsTouching’ 和 ‘Rigidbody2D.IsTouchingLayers’ 来使’Collider2D’和’Physics2D’更相近。
Physics 2D: Renamed ‘AreaEffector2D.forceDirection’ to ‘AreaEffector2D.forceAngle’ (sciprts are automaticallly updated).
Physics 2D:修改 ‘AreaEffector2D.forceDirection’为 ‘AreaEffector2D.forceAngle’ (脚本自动更新).
Physics: Report detailed error when generating collision meshes, also during asset import.
Simplifies troubleshooting creation of non-triangle collision meshes.
Physics:报告更详细的错误当生产碰撞模型时，也包括资源导入时。简化了非三角碰撞模型的故障诊断。
Substance: New Substance features introduced by Substance Designer 5.0 are now supported.
Substance:被Substance Designer 5.0引进的新的Substance现在被支持了。
Terrain: TerrainData.alphamapTextures is now public.
Terrain： TerrainData.alphamapTextures是共有的了。
Windows Standalone: Hint to AMD driver that discrete GPU should be used, rather than integrated GPU.
Windows Standalone:暗示，AMD的驱动程序，应该使用离散GPU，而不是集成的GPU。
XboxOne: Lightmap files are now listed in the package manifest in the same chunk as the scene that uses them.
XboxOne：光照图文件现在与使用它们的场景列在相同的文件清单块中。
XboxOne: Unity is now built with the April 2015 XDK. You will need to install the April 2015 XDK on your PC and use the same or later recovery on your console.
XboxOne：Unity现在使用April 2015XDK编译。你需要安装Apil2015XDK到你的电脑上并且在你的控制台上使用相同的或更新的。
XboxOne: Updated docs to reflect terminology and tools in latest XDK, and added a section on Packaging.
XboxOne：更新文档以反映新XDK的术语和工具，加上Packaging的一部分。
XboxOne: Worker threads created by Unity’s core systems (Physics, AI) will no longer run on cores 0 and 1, which are reserved for the Rendering thread and Unity’s main thread respectively. This will be a performance gain in most cases by avoiding thread context switches.
XboxOne：被Unity’s 核心系统(Physics，AI)创建的工作线程不在暂用核心的 0和1，它们分别被预留为渲染线程或主线程。在大多数情况下，这将是一个性能增益，避免线程上下文切换。
