Trying to upgrade from a 2021 release to the latest one, absolutely no idea whether this will work or not...
Originally I abandoned this install because the API I used to integrate a DIY addressable LED strip (controlled by a media player entity, changed colour to match the cover art) was removed and replaced with something else, and I didn't have time to redevelop it.
For a while its been possible to do something pretty similar with WLED - at that point I was just putting off the upgrades to not break anything ๐
At this point it's probably a better idea to re-install but let's see how this goes!
Do a backup first, if the update does go south the backup might apply to a new install
On the plus side, if the update works there is a good automated backup system now, so it won't be an issue again, I suppose.
