La X.org foundation ha annunciato il rilascio di X11R7.7, release 7.7 di X Window System. Questa release è parte delle celebrazioni per il 25esimo anniversario del rilascio di X Window System version 11, avvenuto il 15 settembre 1987. La prossima release di X11, X11R7.8, sarà disponibile nel 2013.

The X.Org Foundation and the global community of X.Org developers announce the release of X11R7.7 - Release 7.7 of the X Window System, Version 11. This release is the eighth modular release of the X Window System. The next full release will be X11R7.8 and may happen in 2013.

This release is part of our celebration of 25 years of X11, recognizing the 25th anniversary of X Window System Version 11, Release 1 (X11R1) on September 15, 1987. We will continue this celebration later this year at the X.Org Developer Conference, hosted by SuSE in Nürnberg, Germany on September 19-21.

X11R7.7 supports Linux, BSD, Solaris, Mac OS X, Microsoft Windows and GNU Hurd systems. It incorporates both new features and stability and correctness fixes, including support for reporting multi-touch events from touchpads and touchscreens which can report input from more than one finger at a time, smoother scrolling from scroll wheels, better cross referencing & formatting of the documentation, pointer barriers to control cursor movement, and synchronization fences to coordinate between X and other rendering engines such as OpenGL.

Khronos Group ha annunciato il rilascio delle specifiche OpenGL 4.2. Le specifiche complete sono disponibili a questa pagina.

New functionality in the OpenGL 4.2 specification includes:
  • enabling shaders with atomic counters and load/store/atomic read-modify-write operations to a single level of a texture.  These capabilities can be combined, for example, to maintain a counter at each pixel in a buffer object for single-rendering-pass order-independent transparency;
  • capturing GPU-tessellated geometry and drawing multiple instances of the result of a transform feedback to enable complex objects to be efficiently repositioned and replicated;
  • modifying an arbitrary subset of a compressed texture, without having to re-download the whole texture to the GPU for significant performance improvements;
  • packing multiple 8 and 16 bit values into a single 32-bit value for efficient shader processing with significantly reduced  memory storage and bandwidth, especially useful when transferring data between shader stages.
