[dependabot]

Bumps github.com/prometheus-operator/prometheus-operator/pkg/apis/monitoring from 0.91.0 to 0.94.1.

Release notes

Sourced from github.com/prometheus-operator/prometheus-operator/pkg/apis/monitoring's releases.

0.94.1 / 2026-09-23

• [BUGFIX] Restore update permission on finalizer subresources in the operator's ClusterRole, required by OwnerReferencesPermissionEnforcement when blockOwnerDeletion is set. #8830

0.94.0 / 2026-09-09

• [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

0.93.1 / 2026-08-10

• [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

0.93.0 / 2026-07-28

• [CHANGE] Switch from uint to int types in the Go definition of the CRDs and add API validations to reject negative values. #8662 #8666
• [CHANGE] Keep local Prometheus compaction enabled when the Thanos sidecar uploads to object storage, for Prometheus >= v3.9.0 and Thanos >= v0.41.0. The operator now coordinates uploads through the shipper meta file (--storage.tsdb.delay-compact-file.path, --shipper.meta-file-name, --shipper.ignore-unequal-block-size) instead of disabling compaction. Set spec.disableCompaction: true to keep the previous behavior. #8694
• [CHANGE] Define a default value of 1 for .spec.shards for Prometheus and PrometheusAgent CRDs. #8691
• [CHANGE/BUGFIX] Add validation markers to all unsigned int fields to reject negative values. #8662
• [CHANGE/BUGFIX] Disable metadata sending when the remote-write configuration uses message version v2.0. #8700
• [FEATURE] Add updateMessage field to the Slack receiver in the AlertmanagerConfig CRD. #8506
• [FEATURE] Add chunkEncoding field to TSDBSpec for runtime float encoding selection in Prometheus and PrometheusAgent CRDs. #8675
• [ENHANCEMENT] Use pod's name as the peer name for Alertmanager >= v0.30.0. #8705
• [BUGFIX] Create IPv6 EndpointSlice for the kubelet Service on dual-stack clusters. #8682

0.92.1 / 2026-06-30

• [BUGFIX] Fix "namespace not found" errors when the operator watches monitoring and workload resources in different resources. #8658

0.92.0 / 2026-06-18

[!NOTE] The PrometheusTopologySharding and PrometheusShardRetentionPolicy feature gates have been promoted to Beta in this release and are now enabled by default. See the sharding documentation for details.

• [CHANGE] Add URL validation for the tokenUrl field in OAuth2 configuration across all CRDs. #8579
• [CHANGE] Add URL validation for the url field in RemoteReadSpec in Prometheus CRD. #8596
• [FEATURE] Migrate retention options from CLI flags to the config file for Prometheus CRD (Prometheus >= v3 uses the config file; older versions continue to use CLI flags). #8547
• [FEATURE] Add staleSeriesCompactionThreshold field to TSDBSpec in Prometheus and PrometheusAgent CRDs. #8563
• [FEATURE] Add labelNameUnderscoreSanitization and labelNamePreserveMultipleUnderscores fields to OTLPConfig in Prometheus and PrometheusAgent CRDs. #8562
• [FEATURE] Add payload field to Webhook receiver in AlertmanagerConfig CRD. #8507
• [ENHANCEMENT] Use pod topology labels for zone sharding on Kubernetes >= 1.35 when the PrometheusTopologySharding feature gate is enabled (removes the need for attachMetadata.node=true). #8564
• [ENHANCEMENT] Add validation for the Slack update_message field in Alertmanager configuration Secret. #8556
