Now comes with Go 1.17 pre-installed. To match production
docker-compose.yml examples, the development database was
renamed from "photoprism-db" to "mariadb".
Make sure to update your local config files when upgrading as
the name of some config values has changed. The default
config path has changed from "settings" to "config".
Postgres support additionally requires a GORM upgrade to 2.0 (v1.20) as the current version doesn't support generic column types like "bytes" (VARBINARY in MySQL, different in Postgres and other SQL dialects).
