Having issues updating fleet. Currently on Fleet v4.0.0-rc2 and when I tried to upgrade to the latest version (4.2.1) seems to have caused DB issues, was unable to login to the console anymore due to failed authentication. Did the usual download new binaries, prepare db, and start the fleet service. Not sure if there is maybe a known issue or special update instructions that i missed for this version update or do I have to do the versions in between as well to be safe. Using RDS MySQL version 8.0.23. For now just downgraded to previous version of fleet and restored DB, everything is working correctly again.

Did you/can you try logging in with email instead of username? I can't remember if this was already done before rc2, but 4.0.0 stable removes username authentication.

perfect, didnt see mention of that in the release notes. Works though, Thanks!
