   401 * Added a function to get the D3D9 adapter index for a display:
   402     SDL_Direct3D9GetAdapterIndex()
   403 * Added a function to get the D3D9 device for a D3D9 renderer:
   404     SDL_RenderGetD3D9Device()
   405 * Fixed building SDL with the mingw32 toolchain (mingw-w64 is preferred)
   406 * Fixed crash when using two XInput controllers at the same time
   407 * Fixed detecting a mixture of XInput and DirectInput controllers
   408 * Fixed clearing a D3D render target larger than the window
   409 * Improved support for format specifiers in SDL_snprintf()
   411 Mac OS X:
   412 * Added support for retina displays:
   413   Create your window with the SDL_WINDOW_ALLOW_HIGHDPI flag, and then use SDL_GL_GetDrawableSize() to find the actual drawable size. You are responsible for scaling mouse and drawing coordinates appropriately.
   414 * Fixed mouse warping in fullscreen mode
   415 * Right mouse click is emulated by holding the Ctrl key while left clicking
   417 Linux:
   418 * Fixed float audio support with the PulseAudio driver
   419 * Fixed missing line endpoints in the OpenGL renderer on some drivers
   420 * X11 symbols are no longer defined to avoid collisions when linking statically
   422 iOS:
   423 * Fixed status bar visibility on iOS 7
   424 * Flipped the accelerometer Y axis to match expected values
   426 Android:
   427 IMPORTANT: You MUST get the updated SDLActivity.java to match C code
   428 * Moved EGL initialization to native code 
   429 * Fixed the accelerometer axis rotation relative to the device rotation
   430 * Fixed race conditions when handling the EGL context on pause/resume
   431 * Touch devices are available for enumeration immediately after init
   433 Raspberry Pi:
   434 * Added support for the Raspberry Pi, see README-raspberrypi.txt for details
