IMPROVEMENTS
改进
Added warning for NetworkIdentity on child game objects.
在子物体中添加NetworkIdentity警告。
Better error messages when network packets larger than MTU are generated by internal multiplayer systems.
当通过多人网络系统生成的网络包超过MTU时，提供更好的错误消息。
GI: Added the “Min Chart Size” option on the MeshRenderer to allow for lowering chart size in case stiching is not needed.
GI：在MeshRenderer中添加”Min Chart Size”选项，来允许不需要缝合时，更低的图片尺寸。
GI: Added the “Ignore Normals” option on the MeshRenderer to skip comparing normals when detecting charts for realtime GI. This can be necessary when using hand authored UVs to avoid chart splits.
GI：在MeshRenderer中添加”Ignore Normals”选项来跳过比较法线，当实时GI检查图片时。当使用手动UVs避免图片碎裂时很重要。
GI: Upgraded Enlighten to 2.22 UN20:
GI：升级Enlighten到2.22 UN20
- An issue has been fixed where AMD Opteron CPUs produced different atlas packing to Intel Xeon CPUs.
- 如下问题已经被修复，AMD Opteron CPU系列产生不同图集包对比英特尔至强系列。
- A crash affecting Linux binaries on CPUs lacking SSE3 instructions has been fixed.
- 修复一个当CPU缺少SSE3指令时，导致Linux二级制包崩溃的问题。

IL2CPP: Allow null checks, array bounds checks, and divide by zero checks to be selectively included or omitted from generated C++ code by using a C# attribute on type, method, or property definitions.
IL2CPP:现在允许null检查，数组边界检查和除零检查，可以选择性的包含或忽略从原生C++代码使用C#属性在类型，方法和属性定义。
iOS/IL2CPP: Enable incremental build support using the “Append” option. Keep the generated code stable across additional, removal, and changes for string literals and non-generic types.
iOS/IL2CPP:启用增量构建支持使用“附加”选项。把生成的代码稳定在额外的去除，和更改字符串和非泛型类型。
Networking: Added more logging info on too-large packets when object state updates exceed the MTU.
Networking：当物体状态更新超过MTU时，添加更多的日志信息为超大的包。
Networking: Added log messages to identify the object and script that cause too-large packets to be generated.
Networking：添加日志消息来标记物体和脚本导致的超大包产生时。
StackTraceLogType.None now works on iOS and Android.
StackTraceLogType.Nono现在工作在iOS和Android上。
