Is there an upgrade Guide for Phoenix 1.8?

There used to be a gist with upgrade instructions for each new Phoenix version. For example here Phoenix 1.7.0 released: Built-in Tailwind, Verified Routes, LiveView Streams, and what's next - Phoenix Blog it is linked at the bottom under “As always, step-by-step upgrade guides are there to take your existing 1.6.x apps up to 1.7.“ (phoenix-1.6.x-1.7-upgrade.md · GitHub).

With 1.8 I see no such link here Phoenix 1.8.0 released! - Phoenix Blog in search only this article shows up Migrate to Phoenix 1.8 guide - DEV Community but it’s not official guide and it uses RC, not the released version. I can still do the minimum necessary changes using changelog ( Changelog for v1.8 — Phoenix v1.8.8 ) but the guides helped with optional changes - seing what needs to be done saved time. Are we left with changelog and diffs from now on or am I missing something?
