December 2025: libsdl-org/sdl2-compat delivered cross-platform flexibility by introducing conditional compilation guards for X11. Implemented the SDL2COMPAT_DISABLE_X11 flag to selectively compile X11-related code, improving portability and reducing platform-specific build issues. Changes focus on preprocessor guards around X11 paths with minimal risk to existing functionality; commit tracks the change for traceability.

Month: 2025-11 — Focused on improving cross-environment test reliability for libsdl-org/sdl2-compat by enabling test builds without X11, reducing environment-specific failures and boosting CI robustness.

October 2025 monthly summary for libsdl-org/sdl2-compat: Delivered an X11 Support Toggle in the CMake build system. Introduced a new CMake option to disable X11 support and refactored the build to conditionally include X11 dependencies and definitions; updated configuration headers and build scripts to reflect the option, enabling X11-less builds on systems without X11. Commit references: 370ee23c5ba8f4340e8068cad9963647dd37ef43, 1e08d586e97960dd426bfb17df11290b4b7a266b. Key achievements: - Added a CMake option to build without X11 on modern Linux - Refactored build to conditionally include X11 dependencies and definitions - Updated configuration headers to reflect the new X11-off option - Enabled X11-less builds across CI and local environments, increasing portability and reliability

July 2025: MAME development focused on stabilizing the SDL audio backend and improving cross-device compatibility. Implemented a defensive fix so the SDL audio backend falls back to 2 channels when a device reports 0 channels, preventing silent or broken audio output. This change reduces user-reported audio issues and enhances overall experience across platforms. The fix is tracked in mamedev/mame with commit 41c0a1e31c060bc1008e2c691b60a9d42998f2cb (sdl_sound.cpp).
