23-

26-
* Upgraded the Cassandra driver used by opscenterd and the agent to 4.x. Local datacenter is now auto-detected. If auto-detection fails, configure `local_dc_pref` in the cluster configuration or via the new "Data Center" field in the UI. (OPSC-17253)

* Fixed CVE-2025-5115 and CVE-2024-6763 by upgrading the jetty-server version pulled in by ring-jetty-adapter to 9.4.58.v20250814. (DSP-24855)
27+
* Upgraded the Cassandra driver used by 'opscenterd' and the agent to v4.x. Local datacenter is now auto-detected. If auto-detection fails, configure `local_dc_pref` in the cluster configuration or through the new "Data Center" field in the User Interface (UI). (OPSC-17253)
2728
* Added SSL truststore and client certificate support to the PostUrl event plugin for secure integration with external HTTPS alerting systems. For full SSL support including SNI, set `enable_curl=True`. (OPSC-17422)
28-
* Added `azcopy_upload_with_sync` to the agent config with a default of false. When set to true uploads done with azcopy will use a sync command instead of a copy adding another layer of insurance that files will not be uploaded if they are already present on the destination. When using this option it is strongly recommended that the `backup_tmp_dir` be on the cassandra data partition as limitations with azcopy prevent the use of symlinks when staging the files for upload. (OPSC-17716)

* Added `azcopy_upload_with_sync` to the agent configuration with a default of 'false'. When set to 'true' an 'azcopy' upload uses a 'sync' rather than a 'copy. This adds another layer of insurance that no files are uploaded if they are already present on the destination. When using this option it is strongly recommended that the `backup_tmp_dir` be on the 'cassandra' data partition because limitations with 'azcopy' prevent the use of symlinks when staging the files for upload.

* Fixed an issue where an agent would continuously retry startup if the API port was already in use. (OPSC-17204)
30-
* Fixed an issue where sessions configured with timeout=0 were unexpectedly garbage-collected under heap pressure. (OPSC-17762)
31-
* Added a new configuration parameter, `extra_user_search_bases`, in the [ldap] section of the opscenterd.conf file. This parameter allows specifying additional LDAP user search bases for authentication, enabling users from multiple Organizational Units (OUs) to authenticate. The parameter accepts a semicolon-separated list of LDAP search bases. This parameter is optional and backward-compatible with existing configurations. (OPSC-17753)
