Hi! I'm soooo looking forward to this!

Would you be willing to bump the AUR package as well? (It's still on 3.8.9) Or is there a way that I can submit a PR for that?

Update: Never mind, didn't read the checklist

[jsjoeio]

Yeah, sorry, we fell behind on updating the AUR package! If you want, you can open a PR here: https://github.com/cdr/code-server-aur

Otherwise, I should be able to get to it before EOD Monday!

Note: when I downloaded the artifacts from CI and tried to run the mac build, I ran into some "unidentified developer" warning messages. Not sure if that will happen if we release so we're going to push until Monday.

EDIT: this went away when I tried a second time. We think it was a hiccup in CI.
