- Added initial support for G-SYNC Compatible monitors. See the README for details.
- Added support for stereo presentation in Vulkan.
- Fixed a bug that could cause OpenGL applications to crash after repeated VT-switches.
- Fixed a bug that could sometimes prevent PRIME displays from being selected in the display settings page of nvidia-settings.
- NVIDIA Video Codec SDK 9.0
A new release of the Video Codec SDK will be available in Q1 2019.

The main features available in this release are listed below:
- Support for Turing NVENC/NVDEC.
- The NVDECODE API (also known as the NVCUVID API) has been updated to support YUV 4:4:4 decoding for HEVC on Turing GPUs.
- NvEncodeAPI has been updated to support HEVC B-frames on Turing GPUs. NvEncodeAPI adds the capability to output the encoded bitstream, and motion vectors from motion estimation-only mode, to video memory. This avoids the overhead of copying the output from system to video memory for processing pipelines operating directly on video memory.
- NvEncodeAPI now accepts CUarrays as input buffers. The SDK contains a sample application to demonstrate how to feed a Vulkan image to NVENC using the Vulkan-CUDA interop.
- Added NVIDIA optical flow support.
A new library libnvidia-opticalflow.so is included in the driver package. The NVIDIA optical flow library can be used for hardware-accelerated computation of optical flow vectors and stereo disparity values. The API header files, sample applications and documentation will be available in a separate Optical Flow SDK package in Q1 2019.

- Removed libnvidia-wfb.so from the driver package. This module was only used on X servers that did not provide their own implementation of libwfb, and all X.Org xserver versions now supported by the driver do so.
- Updated the VDPAU driver to reject decoding to YUV 4:2:2 video surfaces. The NVIDIA VDPAU driver always produces YUV 4:2:0 content. Previously, the VDPAU driver implicitly converted a YUV 4:2:2 video surface to YUV 4:2:0 during decode. Now, the VDPAU driver will fail the decode request.
- Optimized nvidia-installer to only run depmod(1) once when installing, rather than twice (once during the uninstall phase and again when installing new kernel modules).
- Removed the NVreg_UseThreadedInterrupts kernel module parameter from nvidia.ko. This removes the ability to forcibly fall back to an older mechanism (tasklets) for running the bottom-half interrupt handler. Instead, threaded IRQs (the default since 367.44) are always used.
