Unity 5.1 重大发布，新功能全力支持VR开发！
unity 5.1在今天发布了，我们在5.0发布之后并没有松懈太久便立即投入5.1的更新，想要了解5.1全部的更新请访问官方Release Notes, 以下就由小编来描述一下有哪些重大改变：
新功能：
Unity 5.1加入了新的网络功能，你可以从官方文件或是UnityEngine.Networking命名空间来查询更多的细节，通过这个API开发者能从较低阶的传输层传输数据，不管是低阶的NAT支持或是高阶的游戏配对都没 问题；
未来你可以透过 https://multiplayer.unity3d.com 设定你的服务器，目前的RakNet服务器仍然在使用中，但未来会下架；
新的网络管理控制面板能管理多人联机游戏设定；
Unity 5.1整合了Oculus Rift 到编辑模式，只要把Player Settings 里面的 Virtual Reality Supported打勾，执行的时候Game View就会自动切换为左右3D格式，可以从官方文件或查询 UnityEngine.VR 命名空间来了解更多细节；
新的HDR 颜色选择工具：
Graphics: 有支持DXT硬解的平台现在能使用Crunch模式压缩材质，让文件更小但图片压缩损耗也更大；
Graphics: 实验性让Windows支持 OpenGL 4.5 和 ES 3.1，用-force-glcore, -force-gles(20|30|31|31aep) 参数来启用，目前GL4不支持Mac和Linux平台；
Graphics: OpenGL ES 3.1 支持 android；
Unity Analytics: Unity 5.1整合了新的Unity分析系统(目前为测试版本), 代码用法可以查询 Unity Engine.Analytics命名空间；
把Unity Cloud申请的ID填入Player Setting里的”Cloud Project ID”就可以完成基本设定；
访问 http://analytics.unity3d.com来申请所需要的数据；
Unity4.x和 5.0也能用这个服务；
分析报表范例：
现在你能从开始画面登入你的Unity 账号，体验完整的在线功能，你也可以选择脱机工作，只要点选”Work Offline”即可：
也可以从这个窗口管理你的Unity Pro序号：
Editor: 复制对象时，命名增加改变了规则: MyName,MyName (1), MyName (2)
GI: 自动烘焙在 2D项目预设改为”Disabled”关闭；
GI: "continuous baking" 标签改为较短的"Auto"；
Input: 现在新的项目'Fire3' 绑定会从原本的Left Cmd 改为 Left Shift
iOS: 现在预设情况下 iOS 只支持 Metal 和 OpenGL ES 2.0. 如果你需要支持 OpenGL ES 3.0, 你可以从Player Settings里面改；
Networking: 旧的NetworkView组件已被移除；
Physics: Rigidbody2D组件新增了移动约束参数：
