Sometimes you will see an update of supervisor, but if you don’t click on it, Supervisor will update itself eventually. And as said, Supervisor has it’s own release schedule, not tied to HA Core updates.
Hmm are you sure? They updated the UI, new sidebar editor, ovehauled pickers, new BT and zigbee networ visualizers… I’m getting none of that (also, version numbers (except core) are the same as before the upgrade…
There are only two updates to handle in HAOS and that is the HA Core update and the HAOS update.
Supervisor will update automatically and Frontend will be included in HA Core, if there are any updates.
