龙骨混合属性将图片调为叠加属性在Creator现有版本中无法体现，Creator中会默认成无叠加属性的样式。早些的版本是可以体现这个叠加属性样式的，这是新版本的BUG还是去掉了龙骨的这个属性？希望能够保有叠加属性。
更新了哪些内容呢？
调试发现叠加模式没有删的，你把Premultiplied Alpha 勾上试试？
BUG这个问题并没有解决:修复 Mask 组件启用 inverted 后未更新点选检测（hit test）的问题
刚试了，2.0.7没问题。2.0.9rc3仍然存在。
勾选后，log打不出来。
取消勾选 inverted，就行。
我是在mask节点上注册了一个touch_end事件触发打印log。
修复 Mask 组件启用 inverted 后未更新点选检测（hit test）的问题。
这个BUG没修复，还存在
修复 Mask 组件启用 inverted 后未更新点选检测（hit test）的问题
这个BUG还存在
我有个疑问，2.0.6的版本 微信端一直是禁用 动态渲染的，那么新版本BITMAP模式是否在微信端是否能起到作用呢？？
做demo时候，又发现一个问题。不知道算不算BUG。场景里面一个节点，我把组件勾选框取消了，保存场景，在重新打开。居然自动变成了选中状态？？？
这个版本性能方面确实高了很多，已经打新包发布。看得见的进步啊！
2.0.7打开，2个都能出log。
2.0.9rc3打开，只有左边的能出。
使用命令行构建的时候出现：
[22035] 检测到 JavaScript 引擎发生改动，已清空构建缓存。

我们有用自定义引擎
不过最后构建看起来是没问题
2.0.7的时候我就发过一个帖子，猜测是cc.game.restart();之后，anysdk被移除了，现在2.0.9好像还是这个问题
Spine material data is too large,buffer has no space to put in it!!!
You can adjust MAX_MATERIAL_BUFFER_SIZE in Macro
But It’s better to optimize resource to avoid large material.Because it can advance performance
2.0.9 rc3版本spine超过大小，后半段没播出来，打印如上，请问怎么解决
我也遇到过，anysdk变量在cc.game.restart后就变成未定义的，找不到了，然后直接require报错
可以调整MAX_MATERIAL_BUFFER_SIZE宏的大小，在MiddlewareMacro中定义，可以调整为1024，不过也说明了该资源比较消耗性能了，drawcall有点高。
