Earlier this year was the proposed NVIDIA code from NVIDIA for allowing Mesa's GBM to support alternative back-ends. This support is notable given that most Wayland compositors are catering to using Mesa's Generic Buffer Manager (GBM) rather than EGLStreams or other options for buffer management. That support code has now been merged into Mesa 21.2...

Adding to the lengthy list of features for Intel's next-gen Xeon "Sapphire Rapids" processors next year is an admittedly experimental feature called RAR, or Remote Action Requests...

Merged back in Linux 5.4 in late 2019 was the exFAT file-system driver that has proven to be quite mature at this stage with the work led by Samsung under the blessing of Microsoft. There hasn't been much in the way of exFAT file-system driver changes in recent kernel releases given its maturity. Even with Linux 5.14 there are just two exFAT patches but end up being notable at least for some users due to fixing file-system compatibility with some digital cameras...
