- Backends: Added more implicit asserts to detect invalid/redundant calls to Shutdown functions. (#4562)
- Backends: OpenGL3: Fixed our custom GL loader conflicting with user using GL3W. (#4445) [@rokups]
- Backends: WebGPU: Fixed for latest specs. (#4472) [@Kangz]
- Backends: SDL_Renderer: Added SDL_Renderer backend compatible with upcoming SDL 2.0.18. (#3926) [@1bsyl]
- Backends: Metal: Fixed a crash when clipping rect larger than framebuffer is submitted via
a direct unclipped PushClipRect() call. (#4464)
- Backends: OSX: Use mach_absolute_time as CFAbsoluteTimeGetCurrent can jump backwards. (#4557, #4563) [@lfnoise]
- Backends: All renderers: Normalize clipping rect handling across backends. (#4464)
- Examples: Added SDL + SDL_Renderer example in "examples/example_sdl_sdlrenderer/" folder. (#3926) [@1bsyl]
