 The Stackable platform consists of multiple operators that work together.
 Periodically a platform release is made, including all components of the platform at a specific version.
 
+== Release 22.09
+This is our second release of the Stackable Data Platform.
+It contains lots of new features and bugfixes.
+The main features focus on OpenShift support and security.
+
+=== New platform features
+The following new major platform features were added:
+
+OpenShift compatibility::
+We have made continued progress towards OpenShift compability, and the following operators can now be previewed on OpenShift.
+Further improvements are expected in future releases, but no stability or compatibility guarantees are currently made for OpenShift clusters.
+
+* https://github.com/stackabletech/airflow-operator/pull/127[Apache Airflow]
+* https://github.com/stackabletech/hbase-operator/pull/232[Apache HBase]
+* https://github.com/stackabletech/hdfs-operator/pull/225[Apache HDFS]
+* https://github.com/stackabletech/spark-k8s-operator/pull/126[Apache Spark on K8s]
+
+Support for internal and external TLS::
+The following operators support operating the products at a maximal level of transport security by using TLS certificates to secure internal and external communication:
+
+* https://github.com/stackabletech/trino-operator/pull/244[Trino]
+* https://github.com/stackabletech/kafka-operator/pull/442[Apache Kafka]
+* https://github.com/stackabletech/zookeeper-operator/pull/479[Apache ZooKeeper]
+
+LDAP authentication::
+Use a central LDAP server to manage all of your user identities in a single place.
+The following operators added support for LDAP authentication:
+
+* https://github.com/stackabletech/airflow-operator/pull/133[Apache Airflow]
+* https://github.com/stackabletech/nifi-operator/pull/303[Apache NiFi]
+* https://github.com/stackabletech/superset-operator/pull/180[Apache Superset]
+
+=== stackablectl
+
+`stackablectl` now supports deploying ready-to-use demos, which give an end-to-end demonstration of the usage of the Stackable Data Platform.
+The xref:stackablectl::quickstart.adoc[quickstart guide] shows how to get started with `stackablectl`. Here you can see the xref:stackablectl::demos/index.adoc[available demos].
+
+=== Supported Kubernetes versions
+This release supports the following Kubernetes versions:
+
+* `1.24`
+* `1.23`
+* `1.22`
+
+Support for `1.21` was dropped.
+
+=== Upgrade from 22.06
+==== Using stackablectl
+You can list the available releases as follows
+
+[source,console]
+----
+$ stackablectl release list
+RELEASE            RELEASE DATE   DESCRIPTION
+22.09              2022-09-09     Second release focusing on security and OpenShift support
+22.06              2022-06-30     First official release of the Stackable Data Platform
+----
+
+To uninstall the `22.06` release run
+
+[source,console]
+----
+$ stackablectl release uninstall 22.06
+[INFO ] Uninstalling release 22.06
+[INFO ] Uninstalling airflow operator
+[INFO ] Uninstalling commons operator
+# ...
+----
+
+Afterwards you will need to update the CustomResourceDefinitions (CRDs) installed by the Stackable Platform.
+The reason is, that helm will uninstall the operators but not the CRDs.

+
+==== Breaking changes
+
+You will need to adapt your existing CRDs to the following breaking changes:
+
+==== druid-operator
+1. HDFS deep storage is now configurable via the HDFS discovery config map instead of a url to a HDFS name node (https://github.com/stackabletech/druid-operator/pull/262[#262]).
+Instead of
+
+[source,yaml]
+----
+  deepStorage:
+    hdfs:
+      storageDirectory: hdfs://druid-hdfs-namenode-default-0:8020/data
+----
+
+use
+
+[source,yaml]
+----
+  deepStorage:
+    hdfs:
+      configMapName: druid-hdfs
+      directory: /druid
+----
+
+==== kafka-operator
+1. Add TLS encryption and authentication support for internal and client communications. This is breaking for clients because the cluster is secured per default, which results in a client port change (https://github.com/stackabletech/kafka-operator/pull/442[#442]).
+If you don't want to use TLS to secure your Kafka cluster you can restore the old behavior by using the `tls` attribute as follows:
+
+[source,yaml]
+----
+apiVersion: kafka.stackable.tech/v1alpha1
+kind: KafkaCluster
+# ...
+spec:
+  config:
+    tls: null
+  # ...
+----
+
+==== trino-operator
+1. TrinoCatalogs now have their own CRD object and get referenced by the TrinoCluster (https://github.com/stackabletech/trino-operator/pull/263[#263]).
+Instead of
+
+[source,yaml]
+----
+apiVersion: trino.stackable.tech/v1alpha1
+kind: TrinoCluster
+# ...
+spec:
+  hiveConfigMapName: hive
+  s3:
+    inline:
+      host: minio
+      port: 9000
+      accessStyle: Path
+      credentials:
+        secretClass: s3-credentials
+  # ...
+----
+
+use
+
+[source,yaml]
+----
+apiVersion: trino.stackable.tech/v1alpha1
+kind: TrinoCluster
+# ...
+spec:
+  catalogLabelSelector:
+    trino: trino
+  # ...
+---
+apiVersion: trino.stackable.tech/v1alpha1
+kind: TrinoCatalog
+metadata:
+  name: hive
+  labels:
+    trino: trino
+spec:
+  connector:
+    hive:
+      metastore:
+        configMap: hive
+      s3:
+        inline:
+          host: minio
+          port: 9000
+          accessStyle: Path
+          credentials:
