+General:

+* Added an API to load a database of Game Controller mappings from a file:

+    

+Windows:

+* Support for OpenGL ES 2.x contexts using either WGL or EGL (natively via

+  the driver or emulated through ANGLE)

 

 Android:

 * Joystick support (minimum SDK version required to build SDL is now 12, 

   the required runtime version remains at 10, but on such devices joystick 

   support won't be available).
