+## 0.24.0 / 2018-10-11
+
+This release has a breaking changes for `prometheus_operator_.*` metrics.
+
+`prometheus_operator_alertmanager_reconcile_errors_total` and `prometheus_operator_prometheus_reconcile_errors_total`
+are now combined and called `prometheus_operator_reconcile_errors_total`.
+Instead the metric has a "controller" label which indicates the errors from the Prometheus or Alertmanager controller.
+
+The same happened with `prometheus_operator_alertmanager_spec_replicas` and `prometheus_operator_prometheus_spec_replicas`
+which is now called `prometheus_operator_spec_replicas` and also has the "controller" label.
+
+The `prometheus_operator_triggered_total` metric now has a "controller" label as well and finally instruments the
+Alertmanager controller.

+# Additional Scrape Configuration
+
+AdditionalScrapeConfigs allows specifying a key of a Secret containing
+additional Prometheus scrape configurations. Scrape configurations specified
+are appended to the configurations generated by the Prometheus Operator.
+
+Job configurations specified must have the form as specified in the official
+[Prometheus documentation](
+https://prometheus.io/docs/prometheus/latest/configuration/configuration/#<scrape_config>).
+As scrape configs are appended, the user is responsible to make sure it is
+valid. *Note* that using this feature may expose the possibility to break
+upgrades of Prometheus.
+
+It is advised to review Prometheus release notes to ensure that no incompatible
+scrape configs are going to break Prometheus after the upgrade.
+
+## Creating an additional configuration
+
+First, you will need to create the additional configuration.
+Below we are making a simple "prometheus" config.  Name this
+`prometheus-additional.yaml` or something similiar.
+
+```
+- job_name: "prometheus"
+  static_configs:
+  - targets: ["localhost:9090"]
+```
+
+Then you will need to make a secret out of this configuration.
+
+```
+kubectl create secret generic additional-scrape-configs --from-file=prometheus-additional.yaml --dry-run -oyaml > additional-scrape-configs.yaml
+```
+
+Next, create a new secret using the base64 encoded output as the value for
+`prometheus-additional.yaml` in the secret.
+
+```
+apiVersion: v1
+data:
+  prometheus-additional.yaml: LSBqb2JfbmFtZTogInByb21ldGhldXMiCiAgc3RhdGljX2NvbmZpZ3M6CiAgLSB0YXJnZXRzOiBbImxvY2FsaG9zdDo5MDkwIl0K
+kind: Secret
+metadata:
+  creationTimestamp: null
+  name: additional-scrape-configs
+```
+
+Finally, reference this additional configuration in your `prometheus.yaml` CRD.
+
+```
+apiVersion: monitoring.coreos.com/v1
+kind: Prometheus
+metadata:
+  name: prometheus
+  labels:
+    prometheus: prometheus
+spec:
+  replicas: 2
+  serviceAccountName: prometheus
+  serviceMonitorSelector:
+    matchLabels:
+      team: frontend
+  additionalScrapeConfigs:
+    name: additional-scrape-configs
+    key: prometheus-additional.yaml
+...
+```
+
+NOTE: Use only one secret for ALL additional scrape configurations.
