New command line options
------------------------

- `--dry-run`: repmgr will attempt to perform the action as far as possible
   without making any changes to the database

Changed command line options
----------------------------


### repmgr

- `--replication-user` is now passed when registering the master server (and
  optionally when registering a standby), *not* during standby clone/follow.
  The value (defaults to the user in the conninfo string) will be stored in
  the repmgr metadata for use by  standby clone/follow..

### repmgrd

- `--monitoring-history` is deprecated and has been replaced by the
  configuration file option `monitoring_history`. This enables the
  setting to be changed without having to modify system service files.
