Some of the headline features in this release are: the removal of support for the Itanium architecture, the first part of the futex2 API, futex support in io_uring, the BPF exceptions mechanism, the bcachefs filesystem, the TCP authentication option, the kernel samepage merging smart scan mode, and networking support for the Landlock security module. See the LWN merge-window summaries (part 1, part 2) and the (in-progress) KernelNewbies 6.7 page for more information.
This should allow nouveau to reclock NVIDIA 2xxx and newer GPUs. Huge step forward for open source NVIDIA drovers and I've been testing this on my laptop for a few weeks now woth the rc kernels and the NVK driver and it's pretty impressive so far.
