- Added support for the following GPUs:
- GeForce GTX 750 Ti
- GeForce GTX 750
- GeForce GTX 745
- GeForce GTX TITAN Black
- Fixed a regression in the NVIDIA kernel module which caused it to
improperly dereference a userspace pointer. This potential security issue was
initially reported to the public at:

- Fixed a bug that could cause OpenGL programs to hang after calling
fork(2).
- Fixed a bug that could cause a multi-threaded OpenGL application to crash
when one of its threads exits after the application has unloaded libGL.
- Added support for GPUs with VDPAU Feature Set E. See the README for
details.
- On GPUs with VDPAU Feature Set E, VDPAU now supports more robust decode
error handling at the cost of a minor performance impact.
- This can be disabled by setting the
- VDPAU_NVIDIA_DISABLE_ERROR_CONCEALMENT environment variable to 1.
- Added support for application profile rule patterns which are logical
operations of subpatterns. See the README for details.
- Added support for a findfile application profile feature which allows
the driver to apply profiles based on matching files in the same directory as
the process executable. See the README for details.
- Fixed a bug that caused nvidia-installer to log the automatically
selected answers to some user prompts without logging the prompt text itself,
when running in silent mode.
- Improved performance of OpenGL applications when used in conjunction with
the X driver's composition pipeline. The composition pipeline may be explicitly
enabled by using the ForceCompositionPipeline or ForceFullCompositionPipeline
MetaMode options, or implicitly enabled when certain features such as some
XRandR transformations, rotation,Warp Blend, PRIME, and NvFBC are used.
- Fixed a bug that could cause nvidia-settings to compute incorrect gamma
ramps when adjusting the color correction sliders.
- Updated the nvidia-settings control panel to allow the selection of
display devices using RandR and target ID names when making queries targeted
towards specific display devices.
- Fixed a bug that prevented some dropdown menus in the nvidia-settings
control panel from working correctly on older versions of GTK+ (e.g. 2.10.x).
- Updated the nvidia-settings control panel to provide help text for
application profile keys and suggestions for valid key names when configuring
application profiles.
- Updated the nvidia-settings control panel to populate the dropdown menu
of stereo modes with only those modes which are available.
- Fixed a bug that could cause applications using the OpenGL extension
ARB_query_buffer_object to crash under Xinerama.
- Fixed a bug that caused high pixelclock HDMI modes (e.g. as used with 4K
resolutions) to be erroneously reported as dual-link in the nvidia-settings
control panel.
- Fixed a bug that could cause poor stereo synchronization in large
multi-monitor setups using 3D Vision, due to failed hardwarehandshaking on some
of the monitors.
- Fixed a bug that prevented some DisplayPort 1.2 displays from being
properly restored after a VT switch.
- Renamed per GPU proc directories in /proc/driver/nvidia/gpus/ with GPU's
bus location represented in domain:bus:device.function format.
- Added 64-bit EGL and OpenGL ES libraries to 64-bit driver packages.
- Changed format of Bus Location field reported in the
/proc/driver/nvidia/gpus/0..N/information files from
domain:bus.device.function to domain:bus:device.function to match
- the lspci format.
- Fixed a bug in the GLX_EXT_buffer_age extension where incorrect ages
would be returned unless triple buffering was enabled.
- Updated the NVIDIA X driver to load the NVIDIA kernel module using
`nvidia-modprobe`, rather than the XFree86 DDX helper function
xf86LoadKernelModule().
- Changed the driver's default behavior to stop deleting RandR 1.2 output
corresponding to unused DisplayPort 1.2 devices. Deleting these outputs can
confuse some
