+== Release 22.11
+
+=== 22.11.0
+
+Released on 2022-11-09.
+This is the third release of the Stackable Data Platform, which this time focuses on resource management.
+
+==== New platform features
+
+The following new major platform features were added:
+
+CPU and memory limits configurable::
+
+The operators now https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/[request] resources from Kubernetes for the products and required CPU and memory can now also be configured for all products.
+If your product instances are less performant after the update, the new defaults might be set too low and we recommend to xref:kafka:usage-guide/storage-resources.adoc[set custom requests] for your cluster.
+

+
+==== Breaking changes
+
+You will need to adapt your existing CRDs due to the following breaking changes:
+
+===== Stackable Operator for Apache Spark
+
+The configuration of pod resource requests has been changed to be consistent with other operators that are part of the Stackable Data Platform (https://github.com/stackabletech/spark-k8s-operator/pull/147[#174]).
+
+In the previous version, these were configured like this:
+
+```
+  driver:
+    cores: 1
+    coreLimit: "1200m"
+    memory: "512m"`
+```
+
+From now on, Pod resources can be configured in two different ways.
+The first and recommended way is to add a resources section for each role as the following examples shows:
+
+```
+  driver:
+    resources:
+      cpu:
+        min: "1"
+        max: "1500m"
+      memory:
+        limit: "1Gi"
+```
+
+The second method is to use the `sparkConf` section and and set them individually as spark properties:
+
+```
+  sparkConf:
+    spark.kubernetes.submission.waitAppCompletion: "false"
+    spark.kubernetes.driver.pod.name: "resources-sparkconf-driver"
+    spark.kubernetes.executor.podNamePrefix: "resources-sparkconf"
+    spark.kubernetes.driver.request.cores: "2"
+    spark.kubernetes.driver.limit.cores: "3"
+```
+
+When both methods are used, the settings in the `sparkConf` section override the `resources` configuration.
+
+Note that none of the settings above have any influence over the parallelism used by Spark itself.
+The only supported way to affect this is as follows:
+
+```
+  sparkConf:
+    spark.driver.cores: "3"
+    spark.executor.cores: "3"
+```

+== Release 22.6
+
+This is our first release of the Stackable Data Platform, bringing Kubernetes operators for 12 products as well as <<stackablectl>>, the commandline tool to easily install data products in Kubernetes Operators spin up production ready product applications.
+Also, there are some common features across all operators, such as monitoring, service discovery and configuration overrides.
+Find the <<Platform features>>, <<stackablectl,stackablectl features>> and <<operators>> below.
+
+Please report any issues you find in the specific operator repositories or in our dedicated github.com/stackabletech/issues/[issues] repository.
+You may also join us in our https://slack.stackable.tech[Slack] community or https://stackable.tech[contact us via our homepage].
+
+While we are very proud of this release it is our first one and we'll add new features and fix bugs all the time and will have regular releases from now on.
+
+=== 22.6.0
+
+==== Platform features
+
+Easily install production ready data applications::
+
+Using a familiar declarative approach, users can easily install data applications such as Apache Kafka or Trino across multiple cloud Kubernetes providers or on their own data centers.
+The installation process is fully automated while also providing the flexibility for the user to tune relevant aspects of each application.
+
+Monitoring::
+
+All products have monitoring with prometheus enabled.
+xref:operators:monitoring.adoc[Learn more]
+
+Service discovery::
+
+Products on the Stackable platform use service discovery to easily interconnect with each other.
+xref:concepts:service_discovery.adoc[Learn more]
+
+Configuration overrides::
+
+All operators support configuration overrides, these are documented in the specific operator documentation pages.
+
+Common S3 configuration::
+
+Many products support connecting to S3 to load and/or store data.
+There is a common resource for S3 connections and buckets across all operators that can be reused.
+xref:concepts:s3.adoc[Learn more]
+
+Roles and role groups::
+
+To support hybrid hardware clusters, the Stackable platform uses the concept of role groups.
+Services and applications can be configured to maximize hardware efficiency.
+
+Standardized::
+
+Learn once reuse everywhere.
+We use the same conventions in all our operators.
+Configure your LDAP or S3 connections once and reuse them everywhere.
+All our operators reuse the same CRD structure as well.
+
+[#stackablectl]
+==== stackablectl
+
+xref:management:stackablectl:index.adoc[stackablectl] is used to install and interact with the operators, either individually or with multiple at once.
