There's only a handful of more bug-fixes and back-ports in the X Server 1.8.2 Release Candidate 2 version, but some tricky DRI2 back-ports did get pulled in. The release announcement with change details can be found on xorg-announce. The final version of X.Org Server 1.8.2 should come soon, which is expected to be the final point release in the 1.8 series.
Meanwhile, X.Org Server 1.9 is progressing well and is still on target for release in August. Its first release candidate came last week.
