v0.94.0: 0.94.0 / 2026-09-09

Compare Source

• [CHANGE] Update the default Alertmanager version to v0.34.0 and discard zero-value duration fields (retention, clusterGossipInterval, clusterPushpullInterval, clusterPeerTimeout) in Alertmanager resources instead of passing them as CLI flags, which Alertmanager rejects and can cause startup failures. Ignored fields are reported via the IgnoredFields status condition. #​8800
• [CHANGE] Add named enum types for Hetzner, Docker Swarm, and OpenStack service discovery fields in the ScrapeConfig CRD (HetznerRole, DockerSwarmRole, OpenStackAvailability). #​8789
• [CHANGE] Reject empty strings in namespaceDiscovery.names, consulSDConfig.services, and consulSDConfig.tags list fields in the ScrapeConfig CRD. #​8786
• [FEATURE] Add retentionPercentage field to Prometheus and PrometheusAgent CRDs for volume-based retention (requires Prometheus >= v3.11.0). Setting only the percentage no longer falls back to the default 24h time-based retention. #​8728
• [FEATURE] Add clusterPeerName field to Alertmanager CRD to override the --cluster.peer-name flag (requires Alertmanager >= v0.30.0). #​8767
• [FEATURE] Expose status conditions as Prometheus metrics for Prometheus, PrometheusAgent, Alertmanager, and ThanosRuler resources (prometheus_operator_<resource>_status_condition). #​8719
• [ENHANCEMENT] Tighten the operator's ClusterRole by replacing wildcard verbs with explicit permissions per resource. #​8752
• [ENHANCEMENT] Support webhook_url_file for Discord receiver in Alertmanager configuration Secret (requires Alertmanager >= v0.28.0). #​8035
• [BUGFIX] Require Thanos >= v0.42.0 for delayed compaction with object storage uploads, raised from v0.41.0. Thanos v0.41.0 mis-validates the delayed-compaction paths and the sidecar crash-loops; deployments pinned to v0.41.0 fall back to disabling local compaction. #​8764
• [BUGFIX] Add URL validation for Mattermost receiver fields in Alertmanager configuration Secret. #​8225
• [BUGFIX] Fix operator panic when AlertmanagerConfig Pushover receivers use userKeyFile or tokenFile instead of secret selectors. #​8775
• [BUGFIX] Fix operator panic when kubelet Service synchronization fails and the service is unavailable. #​8743
• [BUGFIX] Fix resources stuck during deletion when the informer misses the deletion timestamp update. #​8727
• [BUGFIX] Fix TracingConfig fields in Prometheus CRD not being serialized due to invalid JSON struct tags. #​8730
• [BUGFIX] Fix externalId version gating for Alertmanager SigV4 configuration to require version >= v0.34.0 (was incorrectly set to v0.33.0). #​8759

v0.93.1: 0.93.1 / 2026-08-10

Compare Source

• [BUGFIX] Fix duplicate kubelet targets for nodes reporting several addresses of the same IP family. #​8739
• [BUGFIX] Fix argument list for Thanos containers when custom TLS ciphers or curves are specified. #​8749
