No legacy driver updates though.


    * Added support for the following GPUs:
            GeForce G102M
            GeForce GT 220
            GeForce G210
            GeForce G210M
            GeForce GT 230M
            GeForce GT 240M
            GeForce GTS 250M
            GeForce GTS 260M Added support for OpenGL 3.2.
  * * Updated the NVIDIA X driver to allow, on GeForce 8 or greater
      GPUs, more modes to validate on digital display devices whose
      EDIDs report very constrained HorizSync or VertRefresh ranges.
    * Fixed a randomly occurring X server crash caused by the
      PixmapCache option.
    * Increased the allowed amount of overscan compensation from 100 to 200.
    * On GPUs with VDPAU feature set B, VDPAU's handling of some
      corrupted or incorrectly formatted H.264 and MPEG streams has been
    * Fixed a memory allocation problem with pre-GeForce 8 GPUs that
      caused GLX_EXT_texture_from_pixmap clients (e.g., Compiz, KDE 4)
      to display incorrect contents.
    * Added support for X.Org xserver (also known as 1.7.0
      RC1). Add a new OverscanCompensation NV-CONTROL attribute,
      available on GeForce 8 and higher. This option specifies the
      amount of overscan compensation to apply to the current mode. It
      is measured in raster pixels, i.e. pixels as specified in the
      current mode's backend timings.
    * Added GLX support for OpenGL 3.2 context profiles through the
    * GLX_ARB_create_context_profile.
    * Added support for IgnoreEDIDChecksum X configuration option, which
      can be used to force the X driver to accept the EDID of a display
      device even when the checksum is invalid. Please see the README
      IgnoreEDIDChecksum description for a caution and details of use.
    * Added support for configuring the GPU's fan speed; see the
      "Coolbits" X configuration option in the README.
    * Fixed a bug in VDPAU that could cause visible corruption near the
      bottom edge of the picture when decoding VC-1 simple/main profile
      clips whose heights are not exact multiples of 16 pixels, on GPUs
      with VDPAU feature set A.
    * On GPUs with VDPAU feature set C, VDPAU now supports decoding
      MPEG-4 Part 2, DivX 4, and DivX 5 video. The VDPAU API has been
      enhanced to expose this feature.
    * On GPUs with VDPAU feature set C, VDPAU now supports a higher
      quality video scaling algorithm. The VDPAU API has been enhanced
      to expose this feature.
    * Added code to reject screen modes based on available DisplayPort
      link bandwidth. Fixes display corruption caused by allowing high
      bandwidth modes on display devices that can't handle them, such as
      certain DisplayPort-to-VGA adapters that only support 2
      DisplayPort lanes.
    * Fixed an initialization problem on some mobile GPUs.
    * Worked around X.Org X server Bugzilla bug #22804. This bug allows
      X clients to send invalid XGetImage requests to the hardware,
      leading to screen corruption or hangs. This was most commonly
      triggered by running JDownloader in KDE 4.
    * Fixed a crash in nvidia-settings displaying GPU information when
      in Xinerama.
    * Added GLX protocol support (i.e., for GLX indirect rendering) for
      the following OpenGL extensions:
    * Added unofficial GLX protocol support (i.e., for GLX indirect
      rendering) for the following OpenGL extensions:
            GL_NV_vertex_program4 GLX protocol for GL_EXT_vertex_array was also updated to
      incorporate rendering using GL_ARB_vertex_buffer_object. Use of
      these extensions with GLX indirect rendering requires the
      AllowUnofficialGLXProtocol X configuration option and the
      __GL_ALLOW_UNOFFICIAL_PROTOCOL environment variable.
    * Fixed glXQueryVersion to report GLX version 1.4. NVIDIA's GLX
      version has been 1.4 for several releases, and was already
      reported as 1.4 in the GLX client and GLX server version strings.
    * Fixed a problem that caused window border corruption when the
      screen is rotated.
    * Added support for configuring the GPU PowerMizer Mode on GeForce 8
      or later GPUs with multiple performance levels via nvidia-settings
      and NV-CONTROL.
