      * Previously, `AlertmanagerConfig` objects with invalid child routes generated invalid Alertmanager configuration leading to Alertmanager disruption. With this release, Prometheus Operator rejects such `AlertmanagerConfig` objects, and users receive a warning about the invalid child routes in logs.

      User Workload Monitoring Alertmanager configuration can get screwed by not correctly sanitized CR content

       

      Customer recently encountered that malformed CR content will prevent User Workload Monitoring Alertmanager configuration.

              routes:
          - receiver: "XXXX" # optional route
            matchers:
              - severity: "!~'^critical$'"

      will be added as CR but rejected by Alertmanager due to quoting issue.

      err="invalid label name \"\""

      Even though we should have some sanitizing implemented, it seems we missed that corner case.
