SDL has been released in version 3.4.16.

SDL (Simple DirectMedia Layer) is a cross-platform library that gives developers low-level access to audio, keyboard, mouse, joystick, and graphics hardware, and forms the foundation of many games and emulators. This update is a pure bugfix release, fixing issues in X11 windows, the GPU API, Nintendo Joy-Con calibration, and BMP loading, among others.

This is a stable bugfix release, with the following changes:

• Fixed loading BMP files with < 8 bits per pixel and odd widths
• Fixed the depth format sample count support check in the GPU API
• Fixed the SDL_QueryGPUFence() return value on Apple platforms
• Fixed textures being rendered with half opacity on PS2
• Fixed windows staying on screen after SDL_Quit() on macOS
• Removed WM_TAKE_FOCUS from WM_PROTOCOLS for X11 windows
• Added SDL_HINT_ANDROID_AAUDIO_INPUT_PRESET instead of hard-coding the camcorder preset on Android
• Report SDL_PenInputFlags in SDL_PenProximityEvent
• Fixed vertical high-resolution mouse wheel scaling on evdev
• Fixed joystick stick calibration on Nintendo Joy-Con controllers
