-Repmgr 3 Features
------------------
-
-`repmgr 3` takes advantage of features introduced in PostgreSQL 9.3 and
-later, including timeline following and replication slots, to make setting
-up and managing replication smoother and easier. For earlier PostgreSQL
-versions please continue use the 2.x branch.
-
-New features in `repmgr 3` include:
-
-* using `pg_basebackup` to clone servers
-* support for timeline following, meaning a standby does not have to be
-  restarted after being promoted to master
-* support for cascading replication
-* support for tablespace remapping (in PostgreSQL 9.3 via rsync only)
-* replication slot support (PostgreSQL 9.4 and later)
-* usability improvements, including better logging and error reporting
-
-Upgrading from repmgr 2
------------------------
-
-`repmgr 3` is largely compatible with `repmgr 2`; the only step required
-to upgrade is to update the `repl_nodes` table to the definition needed
-by `repmgr 3`. See the file `sql/repmgr2_repmgr3.sql` for details on how
-to do this.
-
-`repmgrd` must *not* be running while `repl_nodes` is being updated.
-
-Existing `repmgr.conf` files can be retained as-is.
