+⚠️ Previous versions of this snap set an incorrect path in the PostgreSQL configuration file. As a result, some settings may not be loaded after some updates. The snap will fix this when updated *after* this version. To fix this immediately, change the last line in `/var/snap/mastodon-server/current/postgres/data/postgres.conf` to `include_if_exists = '/var/snap/mastodon-server/current/postgres/config/postgresql.conf'` and restart the snap.
