** Summary changed:

- New stable release - 185.18.31 - available but see WARNING
+ New stable release - 185.18.36 - should replace 185.18.31 ASAP

** Description changed:

  As per ftp://download.nvidia.com/XFree86/Linux-x86_64/latest.txt, this
  is the new, latest, stable driver.
  
- For those willing to test it, it is also in the NVIDIA-VDPAU PPA

- ************************************************************************************
- *** WARNING!  I have tried it with both Intrepid and Karmic, and it completely fails to run,
- ***                    leaving crash information in the logs.  See comments below.

+ This version finally fixes the problems with mobile GPUs that have
+ plagued the 185 series lately.  I have tested it on Hardy, Intrepid,
+ Jaunty and Karmic.  Please update this ASAP.  It is important to replace
+ the defective .31 build as soon as possible.
+ 
+ It is also in the NVIDIA-VDPAU PPA (https://launchpad.net/~nvidia-
+ vdpau/+archive/ppa), as well as being at
+ ftp://download.nvidia.com/XFree86/Linux-x86_64/185.18.36.
  
  --------------------------------------------------------------------------------
+ 
+ Release highlights since 185.18.31:
+ 
+     * Fixed a bug that caused kernel panics when starting X on some mobile GPUs.
+     * Fixed an interaction problem between VDPAU and PowerMizer when using VDPAU solely as a display mechanism, and not to decode video streams. The GPU performance level should now be raised, if required, in this scenario.
+     * Fixed VDPAU to avoid "display preemption" in some cases where a VdpOutputSurface is deleted while it is still active (either queued or visible) in a VdpPresentationQueue. In particular, this can occur in MPlayer when using the "-fs" option, and could completely prevent VDPAU from operating successfully, depending on the exact timing conditions.
  
  Release highlights since 185.18.29:
  
      * Fixed a crash on certain mobile GPUs.
  
  Release highlights since 185.18.14:
  
      * Added code to forcibly terminate long-running CUDA kernels when Ctrl-C is pressed.
      * Fixed a bug that could cause occasional memory corruption problems or segmentation faults when running OpenGL applications on Quadro GPUs.
      * Fixed a deadlock in the OpenGL library that could be triggered in certain rare circumstances on Quadro GPUs.
      * Fixed an interaction problem between PowerMizer and CUDA applications that caused the performance level to be reduced while the CUDA kernel is running.
      * Made CUDA compute-exclusive mode persistent across GPU resets.
      * Fixed the order of outputs in the GPUScaling nvidia-settings property.
      * Fixed a bug that caused graphics corruption in some OpenGL applications when the Unified Back Buffer is enabled the application window is moved.
      * Fixed a bug that caused glXGetVideoSyncSGI, glXWaitVideoSyncSGI, and glXGetRefreshRateSGI to operate on the wrong screen when there are multiple X screens.
      * Fixed a bug that causes corruption or GPU errors when an application paints a redirected window whose background is set to ParentRelative on X.Org servers older than 1.5. This was typically triggered by running Kopete while using Compiz or Beryl.
      * Fixed a bug in VDPAU that could cause visible corruption when decoding H.264 clips with alternating frame/field coded reference pictures, and a video surface is concurrently removed from the DPB, and re-used as the decode target, in a single decode operation. This affected all GPUs supported by VDPAU.
      * Fixed a bug in VDPAU that could cause visible corruption near the bottom edge of the picture when decoding VC-1 advanced profile clips whose heights are not exact multiples of 16 pixels, on G98 and MCP7x (IGP) GPUs.
      * Enhanced VDPAU to better handle corrupt/invalid H.264 bitstreams on G84, G86, G92, G94, G96, or GT200 GPUs. This should prevent most cases of "display preemption" that are caused by bitstream errors.
      * Fixed an X server crash when using the VDPAU overlay-based presentation queue and VT-switching away from the X server.
      * Enhanced VDPAU's detection of the GPU's video decode capabilities.
      * Fixed a bug in VDPAU that could cause ghosting/flashing issues when decoding H.264 clips, in certain full DPB scenarios, on G98 and MCP7x.
      * Fixed VDPAU to detect an attempt to destroy the VdpDevice object when other device-owned objects still exist. VDPAU now triggers "display preemption", and returns an error, when this occurs.
      * Enhanced VDPAU's error handling and resource management in presentation queue creation and operation. This change correctly propagates all errors back to the client application, and avoids some resource leaks.
