v0.90.2

Compare Source

Release notes for version 0.90.2

Release date: 08 Aug 2026

• fixed sync-job ignoring defaultRules.rules.<name>.enabled: false, causing disabled rules to reappear in generated VMRule resources. See #​3151

v0.90.1

Compare Source

Release notes for version 0.90.1

Release date: 07 Aug 2026

• fixed sync-job silently ignoring extra fields set under defaultRules.group.spec (such as params and interval) and defaultRules.rules.*.spec. The configured values were not applied to the generated VMRule resources. See #​3149

v0.90.0

Compare Source

Release notes for version 0.90.0

Release date: 06 Aug 2026

• added vldistributed as an alternative to vlsingle and vlcluster for multi-zone VictoriaLogs deployments. Set vldistributed.enabled: true (mutually exclusive with vlsingle and vlcluster). The victorialogs-cluster dashboard and VL alert rules are enabled automatically when vldistributed.enabled is set.

v0.89.0

Release notes for version 0.89.0

Release date: 05 Aug 2026

• bump version of VM components to v1.149.0

v0.88.0

Compare Source

Release notes for version 0.88.0

Release date: 04 Aug 2026

• added syncJob.extraVolumes and syncJob.extraVolumeMounts to allow mounting custom CA certificates into the sync-job pod. To trust a self-signed certificate, create a Secret with the CA cert, mount it via these fields, and set SSL_CERT_FILE=/path/to/ca.crt in syncJob.env. See #​3127
• added per-component namespaceOverride to all operator-managed components (vmsingle, vmcluster, vmagent, vmalert, alertmanager, vmauth, vlsingle, vlcluster, vlagent, vtsingle, vtcluster). Setting <component>.namespaceOverride: <ns> deploys that CR, its Ingress, and its HTTPRoute into a separate namespace while keeping the rest of the stack in the release namespace. Cross-component FQDNs are updated automatically. See #​3113
• restored VM_ENABLEDPROMETHEUSCONVERTER_* env vars when operator.disable_prometheus_converter: true and removed Prometheus CRD names (PodMonitor, ServiceMonitor, etc.) from --controller.disableReconcileFor. In operator v0.68.x the controllersByName map does not include Prometheus CRD names — passing them causes the operator to fail on startup.
