    * Added support for the following GPUs:
            Quadro FX 880M
    * Fixed a bug that caused screen corruption after an application
      released a GLX_NV_present_video device.
    * Fixed an X server crash caused by starting nvidia-settings while X
      was not on the active VT.
    * Fixed an nvidia-settings bug that produced many "Bad argument"
      warning messages when running nvidia-settings --query all.
    * Fixed a bug that caused G-Sync stereo synchronization to fail
      sometimes when enabling frame lock.
    * Fixed a bug that caused OpenGL applications to occasionally crash
      with "double free or corruption" messages when exiting.
    * On GPUs with VDPAU feature set A, enhanced VDPAU's handling of
      some corrupted or incorrectly formatted MPEG-1/2 streams. This
      solves a reported issue with "0testbad.mpg".
    * Fixed a bug in the VDPAU video mixer that caused chroma
      aberrations, and corruption in the right-hand few columns of
      pixels, when post- processing video surfaces with widths not an
      exact multiple of 4 pixels.
    * Fixed a bug that prevented the GPUFanControlState attribute from
      being set on the nvidia-settings command line.
    * Fixed a regression that made the "TVStandard" X configuration
      option cause system hangs with products from the GeForce 6 and 7
      series.
    * Worked around a bug in some AUO laptop flat panels where the
      native mode in the EDID is invalid, leading to a 640x480 desktop
      repeated six times
      across the screen.
    * Increased the maximum number of slices supported by VDPAU for
      MPEG-2 streams, in order to cope with the region 1 DVD "A
      Christmas Story".
    * Added unofficial preliminary support for xorg-server video driver
      ABI version 7, including xorg-server-1.7.99.2.
    * Fix the soname of libvdpau_nvidia.so.1 and libvdpau_trace.so.1 to
      match their filenames.
    * Fixed a performance regression with non-antialiased text in KDE4.
    * Enabled GPU acceleration for many RENDER compositing operations
      that were previously processed in software, including conjoint and
      disjoint blending
      modes and component alpha blending.
    * Added experimental GPU acceleration of the RENDER
      CompositeTrapezoids operation. This can be enabled at runtime by
      running:
            nvidia-settings -a AccelerateTrapezoids=1 This is only supported on the GeForce GTX series or newer
    * products. Fixed a bug in the VDPAU overlay-based presentation
      queue that caused high CPU usage during "put bits" operations when
      more than two surfaces
      were queued.
    * Updated `nvidia-settings --query all` to report all available
      attributes queryable through all NV-CONTROL target types.
    * Enhanced the VDPAU blit-based presentation queue to provide values
      of "first_presentation_time" that have less jitter.
    * Add support for R16F and RG32F GLXFBConfigs when using GeForce 8
      series and higher GPUs.
    * Added support for A2BGR10 32-bit GLX visuals on 30-bit X screens.
      These allow some level of window transparency when using 30-bit
      visuals with GLX and Composite, but they may cause problems with
      older X servers and/or applications.ARGB GLX visuals can be
      disabled by adding:
            Option "AddARGBGLXVisuals" "False" to the X configuration file. 
    * Fixed a problem that caused DisplayPort devices to behave
      incorrectly when DPMS power saving mode was triggered.
    * Updated VDPAU to improve thread concurrency.See the README for
      details.
    * Altered NVIDIA X driver behavior in the case that no display
      devices are connected to the GPU.Previously, in this case, the
      NVIDIA X driver would pretend a CRT was connected to the GPU. Now,
      the NVIDIA X driver will not automatically pretend that any CRTs
      are connected.If the X driver does not detect any connected
      display devices, the X server will fail to start.
      To restore the old behavior, use the ConnectedMonitor X
      configuration option; e.g.,
            Option "ConnectedMonitor" "CRT" Alternatively, if display is not desired, Quadro and Tesla GPU
      users can enable "NoScanout" mode, which bypasses any mode timing
      validation or use of display devices; this is configured with:
            Option "UseDisplayDevice" "none" 
    * Disabled software cursors when the driver is operating in "no
      scanout" (UseDisplayDevice "none") mode.The software cursor image
      is not visible in remote desktop applications or screenshots
      anyway, so having software cursor enabled was unnecessary.
    * Changed glXSwapBuffers() behavior for a pixmap such that it is now
      a no-op in the direct rendering case in order to match the
      indirect case and comply with the GLX spec. Previously, calling
      glXSwapBuffers() on pixmaps in the direct case would swap the
      pixmap's buffers if the pixmap was double buffered.
    * Modified the installation location and names of internal VDPAU
      libraries to conform to conventions and Debian packaging
      guidelines. New versions of libvdpau expect this layout.
      Compatibility with old versions of libvdpau is maintained with
      symlinks.
    * Fixed a bug that could cause errors in graphical applications run
      after a previous application using VDPAU and OpenGL. This
      behaviour was observed when running Gwenole Beauchesne's
      hwdecode-demos application.
    * Modified vdpau.h to increment VDPAU_VERSION, to reflect the fact
      that new features have been added in the past. Also, add the new
      define VDPAU_INTERFACE_VERSION.
    * Fixed a periodic temporary hang in the VDPAU blit-based
      presentation queue.
    * Fixed a problem that caused resolution limitations or corruption
      on certain DisplayPort devices such as the Apple 24" Cinema
      display or some DisplayPort to VGA adapters.
    * Disabled the UseEvents option for GeForce 8 series and higher GPUs
      due to a problem that causes occasional short hangs.It will be
      re-enabled when that bug has been tracked down and fixed.
    * VDPAU now allows multiple streams to be decoded at once, without
      the need to set any environment variables.
