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.
