Over the weekend there was the first X.Org Server 1.12 development snapshot released by Keith Packard. This isn't an official alpha or beta development build yet, but rather just a snapshot to indicate the current development progress of this next major release. Going forward the plan is to tag such development releases at around the same time there are new stable point releases for the previous series.
The merge window for xorg-server 1.12 is still open and the official release isn't expected until H1'2012. In this weekend's release announcement, Keith Packard also shared that due to travelling in New Zealand next February, he's looking at either delaying the release to March or pushing it up to what would be January or early February.
For enthusiasts thinking about trying this first X.Org Server 1.12 development snapshot, there isn't too much to get excited over, but there's still a fair amount of churn.
One item worth noting about xorg-server 1.12 is smooth scrolling support. There's also a variety of input work that's still ongoing.
