Bumps github.com/prometheus-operator/prometheus-operator/pkg/apis/monitoring from 0.91.0 to 0.93.1.

Release notes

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

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
• [BUGFIX] Validate target labels in Probe static configuration to prevent invalid Prometheus scrape configs. #7901
• [BUGFIX] Fix goroutine leak and data race in pollBasedListerWatcher. #8593
• [BUGFIX] Validate ProxyConfig in OAuth2 configuration. #8610
• [BUGFIX] Fix SMTP smarthost format error handling in Alertmanager configuration. #8586
• [BUGFIX] Fix missing return in admission webhook after marshal failure. #8582
• [BUGFIX] Fix FindOwner to return nil on meta.Accessor error. #8585
• [BUGFIX] Fix dropped gzip Close errors in GzipConfig and GunzipConfig. #8573
• [BUGFIX] Fix panic on malformed key=value flag input (e.g. --labels "key"). #8560
