Mesa 11.2.0 Has Been Officially Released
You should already be familiar with what's new to Mesa 11.2 if you do your daily dose of Phoronix reading as we've been talking about it for months. But if you haven't, you can see the Mesa 11.2 Features For When It's Released Very Soon article.
Mesa 11.2 can be downloaded from this Git branch. However, if you're a Linux gamer or Phoronix-reading Linux enthusiast, chances are you'll be more interested in Mesa Git with all of the features building up for Mesa 11.3 this summer and may very well end up being renamed to Mesa 12.0 should the new OpenGL support levels be reached.
