| Type | Description | Addresses |
|---|---|---|
| Security Fix | Failover Manager has been upgraded to use PostgreSQL JDBC Driver version 42.4.1 to address security vulnerability CVE-2022-31197. Note: Failover Manager is not impacted by the vulnerability, but no longer contains the impacted version of the library. | |

| Bug Fix | Failover Manager will now properly choose a standby to promote in rare cases of LSN values being compared incorrectly. | 83186 |
| Bug Fix | Failover Manager now handles extra whitespace in the properties file when running the efm command for cluster status. | |
| Bug Fix | Failover Manager will no longer fail to promote in rare cases where the primary agent is running slowly. | 79847 |
| Bug Fix | Failover Manager properly follows the promotable=false value of a standby that is restarted after being made promotable manually through the efm command. | 83192 |
| Bug Fix | When using physical replication slots, Failover Manager will now drop and recreate slots on standbys when advancing the LSN values on them if they have an xmin value set. | 83910 |
| Bug Fix | Systemd status will now show "inactive" status instead of "failed" after being used to stop a Failover Manager agent. |
