While released yesterday was X.Org Server 1.14 RC1
, there won't be XWayland support for this next X.Org Server release due out in Q2'2013. However, XWayland support continues to be worked on by Wayland developers so X.Org applications/games can be supported.
For those interested in tearing through some patches, Tiago Vignatti has posted his second version of xwm-client patches
. There's many changes compared to his original patches.
The code can also be found for now in this Weston Git repository
and this X.Org Server Git repository
Due to the X.Org Server development cadence, the earliest we'll now see mainline XWayland support in the xorg-server would be around September of next year.
