Sorry, there's actually a newer announcement from October that I couldn't see before. https://lists.x.org/archives/xorg/2021-October/060799.html https://lists.x.org/archives/xorg/2021-October/060799.html >Notable changes since 1.20 include: - The meson support is now fully mature. While autotools support will still be kept for this release series, it will be dropped afterwards. - Glamor support for Xvfb. - Variable refresh rate support in the modesetting driver. - XInput 2.4 support which adds touchpad gestures. - DMX DDX has been removed. - X server now correctly reports display DPI in more cases. This may affect rendering of client applications that have their own workarounds for hi-DPI screens.
