Some other quick picks from it:

-Improved sleep resume speed.

-Improved Bluetooth connection stability.

-The performance overlay can be customized via configuration files.

-An upgraded Arch Linux base for the operating system.

-An upgrade to the KDE Plasma desktop mode.

-Fixed an issue where certain workloads would exhibit severe CPU performance issues unless SMT was manually disabled.

-External storage devices are now auto-mounted when connected to Steam Deck.

That last one is pretty great, I can now much more easily connect my external m.2 enclosures for game storage.
