2This is a list of major changes in SDL's version history.
3
4---------------------------------------------------------------------------
52.0.5:
6---------------------------------------------------------------------------
7
8General:
9* Implemented audio capture support for some platforms
10* Added SDL_DequeueAudio() to retrieve audio when buffer queuing is turned on for audio capture
11* Added events for dragging and dropping text
12* Added events for dragging and dropping multiple items
13* 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.
14* 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.
15* Added SDL_GetHintBoolean() to get the boolean value of a hint
16* Added SDL_RenderSetIntegerScale() to set whether to smoothly scale or use integral multiples of the viewport size when scaling the rendering output
17* Added SDL_CreateRGBSurfaceWithFormat() and SDL_CreateRGBSurfaceWithFormatFrom() to create an SDL surface with a specific pixel format
18* 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.
19* Added SDL_GetWindowBordersSize() which returns the size of the window's borders around the client area
20* 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)
21* Added SDL_SetWindowResizable() to change whether a window is resizable
22* Added SDL_SetWindowOpacity() and SDL_GetWindowOpacity() to affect the window transparency
23* Added SDL_SetWindowModalFor() to set a window as modal for another window
24* Added support for AUDIO_U16LSB and AUDIO_U16MSB to SDL_MixAudioFormat()
25* Fixed flipped images when reading back from target textures when using the OpenGL renderer
26* Fixed texture color modulation with SDL_BLENDMODE_NONE when using the OpenGL renderer
27* Fixed bug where the alpha value of colorkeys was ignored when blitting in some cases
28
29Windows:
30* 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.
31* The hint SDL_HINT_THREAD_STACK_SIZE is now supported on Windows
32* Fixed XBox controller triggers automatically being pulled at startup
33* The first icon from the executable is used as the default window icon at runtime
34* Fixed SDL log messages being printed twice if SDL was built with C library support
35* Reset dead keys when the SDL window loses focus, so dead keys pressed in SDL applications don't affect text input into other applications.
36
37Mac OS X:
38* Fixed selecting the dummy video driver
39* 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.

41* The audio driver has been updated to use AVFoundation for better compatibility with newer versions of Mac OS X
42
43Linux:
44* Added support for the Fcitx IME
45* Added a window event SDL_WINDOWEVENT_TAKE_FOCUS when a window manager asks the SDL window whether it wants to take focus.

47* Added initial support for touchscreens on Raspberry Pi
48
49OpenBSD:
50* SDL_GetBasePath() is now implemented on OpenBSD
