repmgr 4.1.1 contains a number of usability enhancements and bug fixes.
We recommend upgrading to this version as soon as possible. This release can be installed as a simple package upgrade from repmgr 4.0 ~ 4.1.0; repmgrd (if running) should be restarted. See Upgrading repmgr for more details.
repmgr standby switchover --dry-run no longer copies external configuration files to test they can be copied; this avoids making any changes to the target system. (GitHub #491).
repmgr cluster cleanup: add cluster_cleanup event. (GitHub #492).
repmgr standby switchover: improve detection of free walsenders. (GitHub #495).
Improve messages emitted during repmgr standby promote.
Always reopen the log file after receiving SIGHUP. Previously this only happened if a configuration file change was detected. (GitHub #485).
Report version number after logger initialisation. (GitHub #487).
Improve cascaded standby failover handling. (GitHub #480).
Improve reconnection handling after brief network outages; if monitoring data being collected, this could lead to orphaned sessions on the primary. (GitHub #480).
Check promote_command and follow_command are defined when reloading configuration. These were checked on startup but not reload by repmgrd, which made it possible to make repmgrd with invalid values. It's unlikely anyone would want to do this, but we should make it impossible anyway. (GitHub #486).
Text of any failed queries will now be logged as ERROR to assist logfile analysis at log levels higher than DEBUG. (GitHub #498).
repmgr node rejoin: remove new upstream's replication slot if it still exists on the rejoined standby. (GitHub #499).
repmgrd: fix startup on witness node when local data is stale. (GitHub #488, #489).
Truncate version string reported by PostgreSQL if necessary; some distributions insert additional detail after the actual version. (GitHub #490).
