Originally the merge window was supposed to be closing this week, but the reminder sent by Keith Packard about the imminent closure didn't send properly, so he's extended the window by a couple of days. He announced this couple day push back on the mailing list, after which point the X.Org Server 1.14 RC1 release will be tagged.
Among the work that's been piled in the X Server Git repository since September are a variety of fixes including work on XWin, MinGW fixes, DIX work, and nearly two-hundred other commits. As mentioned this morning, X Input 2.3 with Pointer Barrier Events should also make the X.Org Server 1.14 deadline.
Not found in X.Org Server 1.14 -- at least in Git right now -- is any major enhancements for Optimus / Hybrid Graphics support, no DRI3 / DRI Next, and most notably XWayland hasn't yet been merged.
