There are many new features to Mesa 11.2 for those wishing to use stable versions of Mesa over routine Git snapshots. Unfortunately, after the 11.2-RC3 release three weeks ago, there's been nothing new at all.
The Mesa 11.2 branch has been completely silent since three weeks ago when 11.2.0-rc3 was tagged. There also hasn't been any communication on mesa-dev/mesa-announce about this multi-week delay to the 11.2 cycle. Mesa 11.2 should have been released one week past the RC3 release unless an additional RC was warranted.
More details as soon as I hear anything new about the 11.2 release state.
