Most noticeable to the GLAMOR work that landed today is the OpenGL core profile support from the patches originally posted earlier this month and since revised. With the patches, there is core profile support with GLAMOR for EGL/ephyr/XWayland. There's also VBO support for GLAMOR X-Video vertex array objects usage, and more as part of this work.
OpenGL 3.1 is the new targeted version of this universal DDX driver that does 2D acceleration over OpenGL, up until they decide to make use of geometry shaders, according to one of the patches uploaded.
This latest work can be found in the X.Org Server Git and will be released as X.Org Server 1.19 later in the year.
