DRI2
Plans for version 2 of the Direct Rendering Infrastructure, or better known as DRI2, had come about last year at the 2007 X Developers' Summit. DRI2 allows for a number of technical improvements within X.Org graphics drivers, but for end-users it provides accelerated direct rendering to redirected windows. Today though much of DRI2 is now stabilized, but it didn't come without a lot of hard work and a few key revisions.
What's been added in this latest Direct Rendering Infrastructure 2 push is a DRI2CopyRegion request and the framework that allows DRI2 to be extended in future versions. With the CopyRegion request it's mostly a rename from SwapBuffers. No vsync handling or page-flipping support has yet been added to DRI2.
The announcement regarding today's DRI2 update can be read on the X.Org mailing list.
