Linus Torvalds announced the release of the Linux kernel 6.7 on Sunday, 7th January 2024 and as it turns out it's one of the largest releases ever.
From the release announcement Torvalds said:
So we had a little bit more going on last week compared to the holiday week before that, but certainly not enough to make me think we'd want to delay this any further.
End result: 6.7 is (in number of commits: over 17k non-merge commits, with 1k+ merges) one of the largest kernel releases we've ever had, but the extra rc8 week was purely due to timing with the holidays, not about any difficulties with the larger release.
Going over all the notes here's just some of what's included that seem interesting:
- Initial Bcachefs filesystem support.
- Btrfs filesystem gains temporary filesystem fsid (temp_fsid) for use on systems like the Steam Deck, for "root partition A/B testing, or can be used for VM root images".
- NVIDIA GPU System Processor (GSP) firmware support for the Nouveau open source driver.
- Intel Meteor Lake graphics support is now enabled by default.
- Enable seamless boot in more cases for AMD GPUs.
- Plenty of work for bringing up Intel Lunar Lake support.
- More work on FUTEX2 which was originally created to help Linux gaming.
- Plenty of Rust improvements along with an update to the Rust for Linux website.
- Razer Wolverine V2 added to the xpad gamepad driver.
- Various improvements to Logitech's wireless support for many devices.
- A fix for a kernel crash when connecting Nintendo Joycons (reported on Steam Deck).
