Kernel 5.19 released as stable just a few hours ago. Notable features include further Zen 4 APU support, further support for the Intel DG2/Alchemist GPU, idle driver support for Alder Lake processors, initial support for Raptor Lake P processors, Apple M1 NVMe controller support, and tons of other features/bug fixes/performance improvements. There’s also supposedly performance improvements for the HP Dev One. Linus himself wrote regarding the ARM support for MacBooks:

Today marks the release of Linux kernel 5.17. Doesn’t seem to offer much of anything in the gaming landscape, but there’s hardware support for a bunch of new motherboards and processors. Here’s a basic rundown of what’s new: support for AMD’s new P-State driver for AMD Zen 2 APUs – this is particularly good news for the Steam Deck as that is the APU it’s using and P-State delivers better power efficiency.
