@ -7,43 +7,12 @@ This is a list of major changes in SDL's version history.
General:
* SDL headers should now be included as `#include <SDL3/SDL.h>`
* Many functions and symbols have been renamed, see docs/README-migration.md for details
* Many functions and symbols have changed since SDL 2.0, see the [migration guide](docs/README-migration.md) for details
* The preprocessor symbol __MACOSX__ has been renamed __MACOS__
* The preprocessor symbol __IPHONEOS__ has been renamed __IOS__
* M_PI is no longer defined in SDL_stdinc.h, now the symbols SDL_PI_D (double) and SDL_PI_F (float) are available
* SDL_GetWindowWMInfo() returns a standard int result code instead of SDL_bool, and takes SDL_SYSWM_CURRENT_VERSION as a new third parameter
* Renamed hints 'SDL_HINT_VIDEODRIVER' and 'SDL_HINT_AUDIODRIVER' to 'SDL_HINT_VIDEO_DRIVER' and 'SDL_HINT_AUDIO_DRIVER'
* Renamed environment variables 'SDL_VIDEODRIVER' and 'SDL_AUDIODRIVER' to 'SDL_VIDEO_DRIVER' and 'SDL_AUDIO_DRIVER'
* SDL_stdinc.h no longer includes stdio.h, stdlib.h, etc., it only provides the SDL C runtime functionality
* Added SDL_CreateSurface() and SDL_CreateSurfaceFrom() which replace the SDL_CreateRGBSurface*(), and can also be used to create YUV surfaces
* Removed unused 'flags' parameter from SDL_ConvertSurface and SDL_ConvertSurfaceFormat
* Removed 'SDL_GL_CONTEXT_EGL' from OpenGL configuration attributes
* Added SDL_CreateSurface() and SDL_CreateSurfaceFrom() which replace SDL_CreateRGBSurface*(), and can also be used to create YUV surfaces
* SDL_GetTicks() now returns a 64-bit value and the tick values should be directly compared instead of using the SDL_TICKS_PASSED macro
* Added SDL_GetTicksNS() to return the number of nanoseconds since the SDL library initialized
* Added SDL_DelayNS() to specify a delay in nanoseconds, to the highest precision the system will support
* The timestamp member of the SDL_Event structure is now in nanoseconds, filled in with the time the event was generated, or the time it was queued if that's not available
* The `SDL_DISPLAYEVENT_*` and `SDL_WINDOWEVENT_*` events have been moved to top level events
* Intrinsic headers are no longer included in the public SDL headers
* The following functions have been removed, see docs/README-migration.md for details:
* SDL_AudioInit()
* SDL_AudioQuit()
* SDL_CalculateGammaRamp()
* SDL_CreateRGBSurface()
* SDL_CreateRGBSurfaceFrom()
* SDL_CreateRGBSurfaceWithFormat()
* SDL_CreateRGBSurfaceWithFormatFrom()
* SDL_GameControllerGetSensorDataWithTimestamp()
* SDL_GetRevisionNumber()
* SDL_GetWindowBrightness()
* SDL_GetWindowGammaRamp()
* SDL_RWFromFP()
* SDL_SensorGetDataWithTimestamp()
* SDL_SetWindowBrightness()
* SDL_SetWindowGammaRamp()
* SDL_VideoInit()
* SDL_VideoQuit()
* The following hints have been removed, see docs/README-migration.md for details:
* SDL_HINT_IDLE_TIMER_DISABLED
* SDL_HINT_VIDEO_X11_FORCE_EGL
* SDL_HINT_VIDEO_X11_XINERAMA
* SDL_HINT_VIDEO_X11_XVIDMODE
