• BUGFIX: vmalertmanagerconfig: Remove prefix from empty subroute receiver. See #2185.

• BUGFIX: vmoperator: updated OLM configuration to fix OpenShift catalog publishing. See #2195.

• SECURITY: upgrade Go builder from Go1.26.2 to Go1.26.3. See the list of issues addressed in Go1.26.3.

• Dependency: vmoperator: Updated default versions for VM apps to [v1.143.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.
  143.0) version

• Dependency: vmoperator: Updated default versions for VM apps to [v1.142.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.
  142.0) version

• FEATURE: vmauth: previously VMAuth could read configuration only from predefined locations; now VMAuth supports arbitrary filesystem access configuration, allowing users to reference required files directly and reducing configuration workarounds. See #899.

• FEATURE: vmuser: support VMAnomaly CRD in VMUser targetRefs. See [#2141](#2
  141).

• FEATURE: vmdistributed: introduce spec.zones[*].trafficMode property, which allows disable read, write or whole traffic to a zone. See #1995.

• FEATURE: vmagent: support per remote write queues configuration. See [#2138](https://github.com/VictoriaMetrics/operator/iss
  ues/2138).

• BUGFIX: converter: disable all prometheus controllers if CRD group was not found. See [#2838](https
  ://github.com/VictoriaMetrics/helm-charts/issues/2838).

• BUGFIX: vmdistributed: change default load balancing policy for write requests from first_available to least_loaded . This should allow to evenly distribute write load across all VMAgents.

• BUGFIX: vmalertmanagerconfig: fix previously ignored negative values in VMAlertmanagerConfig. See [#2132](https
  ://github.com//issues/2132).

• BUGFIX: vmalertmanager: fixed ignored alertmanager template if it has no discovered VMAlertmanagerconfig CRs or traci
  ng config defined. See #2121.

• BUGFIX: VMCluster, VTCluster and [VLCluster](https://doc
  s.victoriametrics.com/operator/resources/vlcluster/): fixed infinite non-default additional service recreation, when requestsLoadBalancer.enabled: true

• BUGFIX: vmauth: fixed case, when target_path_suffix can be appended multiple times.

• BUGFIX: vmoperator: retry reconcile errors, that may lead to expanding state, before resource could hang in expanding state.

• BUGFIX: vmcluster, vlcluster and [vtcluster](https://doc
  s.victoriametrics.com/operator/resources/vtcluster/): when storage HPA was enabled, generated -storageNode flags could become incorrect after scaling, which could break expected routing to
  storage nodes; now the operator derives storage node count from the current StatefulSet state so generated flags stay correct during HPA-driven scaling. See [#2117](https://github.com/Victo
  riaMetrics/operator/issues/2117).

• BUGFIX: vmdistributed: expose VMClusterSpec parsing error in status, previously it was just swallowed and led to infin
  ite reconciles. See #2113.

• Dependency: vmoperator: Updated default versions for VM apps to v1.140.0 version

• Dependency: vmoperator: Updated default versions for VM apps to v1.139.0 version
  Update note 1: deprecated env variables for Prometheus CRs conversion VM_ENABLEDPROMETHEUSCONVERTER_PODMONITOR, VM_ENABLEDPROMETHEUSCONVERTER_SERVICESCRAPE, VM_ENABLEDPROMETHEUSCONVERTER_PROMETHEUSRULE, VM_ENABLEDPROMETHEUSCONVERTER_PROBE, VM_ENABLEDPROMETHEUSCONVERTER_SCRAPECONFIG. Use -controller.disableReconcileFor command-line flag with comma-separated list of controller names, that should be disabled.
  Update note 2: removed operator_prometheus_converter_watch_events_total metric since migration of Prometheus object watchers to controllers made this counter obsolete.
  Update note 3: made controller.prometheusCRD.resyncPeriod command line flag noop, which was relevant to Prometheus object watchers.
  Update note 4: -eula flag is not set by default anymore for VMBackup and VMRestore. To avoid VMCluster/VMSingle rollouts set spec.vmstorage.vmBackup.acceptEula: true for VMCluster and spec.vmBackup.acceptEula: true" for VMSingle and replace it with spec.license during VMSingle/VMCluster upgrade.
  Update note 5: new flag was introduced, so VMAnomaly pods will be recreated. VMAnomaly version should be at least 1.25.
  Update note 6: fixed port name collision in VMSingle and VMCluster, when VMBackup is enabled. To avoid VMSingle/VMCluster pods recreation set VM_USE_OLD_BACKUP_RESTORE_PORT_NAMES environment variable to true.
  Update note 7: the default VMDistributed unauthorizedUserAccessSpec was removed to allow users to decide whether access should be anonymous or authorized. Please check documentation with examples for unauthorized and authorized access and update your CRs accordingly.
