Bugs are now managed in the SDL bug tracker, here:
http://bugzilla.libsdl.org/
https://bugzilla.libsdl.org/
You may report bugs there, and search to see if a given issue has already
been reported, discussed, and maybe even fixed.

This is a list of major changes in SDL's version history.
---------------------------------------------------------------------------
2.0.5:
---------------------------------------------------------------------------
General:
* Implemented audio capture support for some platforms
* Added SDL_DequeueAudio() to retrieve audio when buffer queuing is turned on for audio capture
* Added events for dragging and dropping text
* Added events for dragging and dropping multiple items
* By default the click raising a window will not be delivered to the SDL application. You can set the hint SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH to "1" to allow that click through to the window.
* Saving a surface with an alpha channel as a BMP will use a newer BMP format that supports alpha information. You can set the hint SDL_HINT_BMP_SAVE_LEGACY_FORMAT to "1" to use the old format.
* Added SDL_GetHintBoolean() to get the boolean value of a hint
* Added SDL_RenderSetIntegerScale() to set whether to smoothly scale or use integral multiples of the viewport size when scaling the rendering output
* Added SDL_CreateRGBSurfaceWithFormat() and SDL_CreateRGBSurfaceWithFormatFrom() to create an SDL surface with a specific pixel format
* Added SDL_GetDisplayUsableBounds() which returns the area usable for windows. For example, on Mac OS X, this subtracts the area occupied by the menu bar and dock.
* Added SDL_GetWindowBordersSize() which returns the size of the window's borders around the client area
* Added a window event SDL_WINDOWEVENT_HIT_TEST when a window had a hit test that wasn't SDL_HITTEST_NORMAL (e.g. in the title bar or window frame)
* Added SDL_SetWindowResizable() to change whether a window is resizable
* Added SDL_SetWindowOpacity() and SDL_GetWindowOpacity() to affect the window transparency
* Added SDL_SetWindowModalFor() to set a window as modal for another window
* Added support for AUDIO_U16LSB and AUDIO_U16MSB to SDL_MixAudioFormat()
* Fixed flipped images when reading back from target textures when using the OpenGL renderer
* Fixed texture color modulation with SDL_BLENDMODE_NONE when using the OpenGL renderer
* Fixed bug where the alpha value of colorkeys was ignored when blitting in some cases
Windows:
* Added a hint SDL_HINT_WINDOWS_DISABLE_THREAD_NAMING to prevent SDL from raising a debugger exception to name threads. This exception can cause problems with .NET applications when running under a debugger.
* The hint SDL_HINT_THREAD_STACK_SIZE is now supported on Windows
* Fixed XBox controller triggers automatically being pulled at startup
* The first icon from the executable is used as the default window icon at runtime
* Fixed SDL log messages being printed twice if SDL was built with C library support
* Reset dead keys when the SDL window loses focus, so dead keys pressed in SDL applications don't affect text input into other applications.
Mac OS X:
* Fixed selecting the dummy video driver
* The caps lock key now generates a pressed event when pressed and a released event when released, instead of a press/release event pair when pressed.
* Fixed mouse wheel events on Mac OS X 10.12
* The audio driver has been updated to use AVFoundation for better compatibility with newer versions of Mac OS X
Linux:
* Added support for the Fcitx IME
* Added a window event SDL_WINDOWEVENT_TAKE_FOCUS when a window manager asks the SDL window whether it wants to take focus.
* Refresh rates are now rounded instead of truncated, e.g. 59.94 Hz is rounded up to 60 Hz instead of 59.
* Added initial support for touchscreens on Raspberry Pi
OpenBSD:
* SDL_GetBasePath() is now implemented on OpenBSD
iOS:
* Added support for dynamically loaded objects on iOS 8 and newer
tvOS:
* Added support for Apple TV
* Added a hint SDL_HINT_APPLE_TV_REMOTE_ALLOW_ROTATION to control whether he Apple TV remote's joystick axes will automatically match the rotation of the remote.
Android:
* Fixed SDL not resizing window when Android screen resolution changes
* Corrected the joystick Z axis reporting for the accelerometer
Emscripten (running in a web browser):
* Many bug fixes and improvements
