0.57.0 / 2022-06-02

The main change introduced by this release is a new v1beta1 API version for the AlertmanagerConfig CRD.

Changes compared to the v1alpha1 API:

• Renamed spec.muteTimeIntervals field to to spec.timeIntervals.
• Removed regex field from the Matcher type.
• Replaced all v1.SecretKeySelector types by the SecretKeySelector type
  • Removed optional field.
  • name and key fields are required.

As a pre-requisite, you need to deploy the admission webhook and configure the conversion webhook in the AlertmanagerConfig CRD object so that users can use both v1alpha1 and v1beta1 versions at the same time. There are more details in Documentation/user-guides/webhook.md about the webhook configuration.

Because of the conversion webhook requirement, the new version is an opt-in feature: the bundle.yaml file and the manifests from
example/prometheus-operator-crd don't deploy the new API version (the manifests to enable the v1beta1 version are under the example/prometheus-operator-crd-full directory). We will wait until v0.59.0 (at least) before enabling the new API version by default.

0.56.1 / 2022-05-03

• [BUGFIX] Avoid unnecessary updates of the Prometheus StatefulSet object. #4762

0.56.0 / 2022-04-20

• [CHANGE] Added validation at the API level for size-based fields of the Prometheus CRD. #4661
• [CHANGE] Added validation at the API level for log level and format fields of the Alertmanager, Prometheus and ThanosRuler CRDs. #4638

It allows to define PodMonitor, ServiceMonitor, Probe or PrometheusRule objects for which the namespace label enforcement (if enabled) should not be applied. This deprecates prometheusRulesExcludedFromEnforce which is still supported but users are encouraged to migrate to the new field. #4397

When the path contains a full path, a volume + volume mount should be explicitly given in the Prometheus spec since the root file system is now read-only. #4566
