- XFS now supports timestamps to Year 2486 rather than Year 2038. XFS will now deprecate the V4 file-system format in 2030. XFS will also deprecate old Irix tweaks in 2025.

- Fsync performance optimizations for Btrfs.

- F2FS improvements including the Age Threshold Garbage Collector, faster file decompression support, NVMe ZNS support, generic casefolding, and more.

- A "volatile" option for OverlayFS to yield faster performance but where syncs are omitted.

- The nosymfollow mount option is added and similar to BSDs for improving system security. The work was led by Google as part of their ChromeOS effort.

- EXT4 now supports fast commits and faster file overwite performance in DIO/DAX modes.

- NFS client support for READ_PLUS that can help with allowing faster read performance of sparse files.

- A DAX mode for FUSE to yield faster performance primarily for VirtIO-FS.

- RAID10 DISCARD improvements.

- Quicker hibernation and resume.

Other Hardware:

- Continued work on USB4 support.

- Hardening against possible DMA attacks by external PCI Express devices.

- Synaptics touchpad improvements for newer laptops, primarily Lenovo devices.

- Device Tree additions for the Purism Librem 5 and other ARM boards.

- Support for the Matias Wireless Aluminum Keyboard by leveraging the hid-apple driver so that all functionality now works.

- A rewrite to the Intel Haswell audio driver for the Lynx Point / Wildcat Point audio DSP hardware.

- Audio output support for the Intel DG1.

- Creative SoundBlaster AE-7 support at long last was tackled by the community.

- Nintendo Switch controller support was upstreamed.


- Support for Amazon Nitro Enclaves and other char/misc churn.

- Many staging updates.

- Many networking subsystem updates.

- Initial landing of the long overdue revamp to printk().

- The introduction of the Vidtv virtual driver for the media subsystem.

- A new static_call() function to help cases where Retpolines are used.
