I think you're best off not upgrading for the time being. It seems like the old auth still works server-side but the the new auth is very, very busted if you are not on a personal plan.
But good news: you can fake out codex-rs into thinking it's not headless by unsetting all SSH environment variables and setting DISPLAY=foo to recover the old behavior.
I didn't upgrade yet but for me codex on a business plan still works, so they didn't deprecate the old auth (yet).
But yeah honestly I've never seen any other repo with so many important issues that are just being closed without fixes.
