X.Org Server 1.19 RC2, Some Prominent XWayland Changes
Missing the 22 October release target, Keith Packard on Friday evening released xorg-server 188.8.131.522 as the second release candidate. He mentions it "should be pretty close to 1.19" and he's just aware of a serious bug causing a crash. The changes in X.org Server 1.19 RC2 involve a few dozen fixes and tweaks to GLAMOR, XWayland, Ephyr, and other areas.
The last-minute XWayland improvements are a bit interesting with adding the pointer warp emulation, relative pointer work, etc.
