-## Notes on Postgres 13 support
-
-If you are new to the operator, you can skip this and just start using the Postgres operator as is, Postgres 13 is ready to go.
-
-The Postgres operator supports Postgres 13 with the new Spilo Image that includes also the recent Patroni version to support PG13 settings.
-More work on optimizing restarts and rolling upgrades is pending.
+## Using Spilo 12 images or lower
 
 If you are already using the Postgres operator in older version with a Spilo 12 Docker image you need to be aware of the changes for the backup path.
-We introduce the major version into the backup path to smoothen the [major version upgrade](docs/administrator.md#minor-and-major-version-upgrade) that is now supported manually.
+We introduce the major version into the backup path to smoothen the [major version upgrade](docs/administrator.md#minor-and-major-version-upgrade) that is now supported.
 
 The new operator configuration can set a compatibility flag *enable_spilo_wal_path_compat* to make Spilo look for wal segments in the current path but also old format paths.
 This comes at potential performance costs and should be disabled after a few days.
