- SDL_RWops is now an opaque struct. - SDL_AllocRW is gone. If an app is creating a custom RWops, they pass the function pointers to SDL_CreateRW(), which are stored internally. - SDL_RWclose is gone, there is only SDL_DestroyRW(), which calls the implementation's `->close` method before freeing other things. - There is only one path to create and use RWops now, so we don't have to worry about whether `->close` will call SDL_DestroyRW, or if this will risk any Properties not being released, etc. - SDL_RWFrom* still works as expected, for getting a RWops without having to supply your own implementation. Objects from these functions are also destroyed with SDL_DestroyRW. - Lots of other cleanup and SDL3ization of the library code.
Simple DirectMedia Layer (SDL) Version 3.0
Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting with README.md. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.
Enjoy!
