+## 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.
+
+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 smooth the major version upgrade that is now supported manually.
+
+The new operator configuration, sets a compatilibty flag *enable_spilo_wal_path_compat* to make Spilo look in current path but also old format paths for wal segments.
+This comes at potential perf. costs, and should be disabled after a few days.
+
+The new Spilo 13 image is: `registry.opensource.zalan.do/acid/spilo-13:2.0-p1`
+
+The last Spilo 12 image is: `registry.opensource.zalan.do/acid/spilo-12:1.6-p5`
