1 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.

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. 40* Fixed mouse wheel events
