Release Highlights

Added support for the following new GPUs:
GeForce GTX 260
GeForce GTX 280
Improved support for RENDER masks, as well as RENDER repeating modes and transformations, for video memory pixmaps.
Added accelerated support for RENDER convolution filters for video memory pixmaps on GeForce 8, 9 and GTX GPUs.
Added an 'AllowSHMPixmaps' X configuration option, which can be used to prevent applications from using shared memory pixmaps; the latter may cause some optimizations in the NVIDIA X driver to be disabled.
Added support for DisplayPort display devices (including 30-bit devices).
Resolved various stability problems on GeForce 8, 9 and GTX GPUs, as well as some GeForce 6 and 7 PCI-E GPUs.
Fixed a bug that resulted in GPU errors when changing the TwinView display configuration while using Compiz.
Further improved the error recovery paths taken in case of GPU command stream corruption.
Removed an old workaround that caused incorrect fake Xinerama information to be reported after enabling a second TwinView display.
Fixed the subpicture component order reported by the NVIDIA X driver's XvMC implementation.
Fixed a problem that could result in IRQs being disabled on some multi-GPU SMP configurations.
Worked around cache flushing problems (on some Linux kernels) that caused corruption and stability problems.
Added experimental support for PCI-E MSI.
Improved compatibility with recent Linux 2.6 kernels.
