 * RenderTexture: added a call back function for `saveToFile()`
 * Primitive: Support Points, Lines and Triagles for rendering
 * SpriteFrameCache: support loading from plist file content data
+* Added a consistent way to set GL context attributes for all platforms
 * Many other small features added and many bugs fixed

 1. The size of vertex and index Buffer is fixed, which means data must be pre allocated.
 2. Batching is not supported.

+## Consistent way to set GL context attributes
+
+Now you can set GL context attributes by override `Application::initGLContextAttrs()`, then set GL context attributes there.
+
+```c++
+void AppDelegate::initGLContextAttrs()
+{
+    // r:8 g:8 a:8 depth:24 stencil:8
+    GLContextAttrs glContextAttrs = {8, 8, 8, 8, 24, 8};
+    GLView::setGLContextAttrs(glContextAttrs);
+}
+```
+
+Now can only support setting bits of `r`, `g`, `b`, `a`, `depth buffer` and `stencil buffer`. We will support other attributes if needed.
