* Added a Vivante video driver that is used on various SoC platforms
* Added an event SDL_RENDER_DEVICE_RESET that is sent from the D3D renderers when the D3D device is lost, and from Android's event loop when the GLES context had to be recreated
* Added a hint SDL_HINT_NO_SIGNAL_HANDLERS to disable SDL's built in signal handling
* Added a hint SDL_HINT_THREAD_STACK_SIZE to set the stack size of SDL's threads
* Added SDL_sqrtf(), SDL_tan(), and SDL_tanf() to the stdlib routines
* Improved support for WAV and BMP files with unusual chunks in them
* Renamed SDL_assert_data to SDL_AssertData and SDL_assert_state to SDL_AssertState
Windows:
* Added support for Windows Phone 8.1

* SDL_SysWMinfo now contains the window HDC
* Added support for Unicode command line options
* Prevent beeping when Alt-key combos are pressed
* SDL_SetTextInputRect() re-positions the OS-rendered IME
Mac OS X:
* Implemented drag-and-drop support
* Improved joystick hot-plug detection
* The SDL_WINDOWEVENT_EXPOSED window event is triggered in the appropriate situations
* Fixed relative mouse mode when the application loses/regains focus
* Fixed bugs related to transitioning to and from Spaces-aware fullscreen-desktop mode
* Fixed the refresh rate of display modes
* SDL_SysWMInfo is now ARC-compatible

iOS:
* Added support for iOS 8
* Added support for the hint SDL_HINT_ACCELEROMETER_AS_JOYSTICK
* Added sRGB OpenGL ES context support on iOS 7+
* Added native resolution support for the iPhone 6 Plus
* The SDL_WINDOW_ALLOW_HIGHDPI window flag now enables high-dpi support, and SDL_GL_GetDrawableSize() or SDL_GetRendererOutputSize() gets the window resolution in pixels
* SDL_GetWindowSize() and display mode sizes are in the "DPI-independent points" coordinate space rather than pixels (matches OS X behavior)
* SDL_SysWMinfo now contains the OpenGL ES framebuffer and color renderbuffer objects used by the window's active GLES view
* Fixed various rotation and orientation issues
* Fixed memory leaks
Android:
* Added a hint SDL_HINT_ANDROID_SEPARATE_MOUSE_AND_TOUCH to prevent mouse events from being registered as touch events
