PSA: Upgrading to F44 COSMIC Atomic? The official rebase docs will leave you stuck on a nightly build. Use the updates branch instead.

Hey r/Fedora,

Just caught a quirk with the F44 COSMIC Atomic release. If you're doing a major version upgrade, the official docs tell you to rebase directly to the main branch (fedora:fedora/44/x86_64/cosmic-atomic).

TL;DR: Don't do that for COSMIC Atomic. The main ref is currently frozen on a pre-release nightly build. Rebasing there means you won't get any new commits or security updates. You'll get older kernel and COSMIC versions than in F43. Rebase to updates branch instead.
