Went from 10.11 to 12.0 and had zero issues. Scaleway/Ubuntu/Docker env with 8GB RAM.

Well one small niggle, I had a custom script setup on Caddy that overrides how certain buckets are sorted because my users are too lazy to follow my instructions. They changed the BucketID string in some way but this more to do with me having a custom script dependant on something they don't guarantee.

Hopefully they allow admins to change a users preferences in the future but currently it has to be done at the user level. I'm sure that will be in a future update.
