+      In previous releases, a logical replication connection required
+      the <literal>replication</literal> keyword in the database column.  As
+      of this release, logical replication matches a normal entry with a
+      database name or keywords such as <literal>all</literal>.  Physical
+      replication continues to use the <literal>replication</literal> keyword.
+      Since built-in logical replication is new in this release as well, this
+      change only affects users of third-party logical replication plugins.
