Description

I was struggling to log into the dashboard against the latest headscale and Claude found that the latest version of the Github had the fix but that the beta branch did not. Please make a beta deployment asap.

Headplane Version

0.6.2-beta.4

Headscale Version

v0.28.0

No, I'll make a final release when I'm done with 0.28 support.
