+
+In the last two months since our [initial preview
release](https://flink.apache.org/news/2022/04/03/release-kubernetes-operator-0.1.0.html)
the community has been hard at work to stabilize and improve the core Flink
Kubernetes Operator logic.
+We are now proud to announce the first production ready release of the
operator project.
+
+## Release Highlights
+
+The Flink Kubernetes Operator 1.0.0 version brings numerous improvements and
new features to almost every aspect of the operator.
+
+ * New **v1beta1** API version & compatibility guarantees
+ * Session Job Management support
+ * Support for Flink 1.13, 1.14 and 1.15
+ * Deployment recovery and rollback
+ * New Operator metrics
+ * Improved configuration management
+ * Custom validators
+ * Savepoint history and cleanup
+
+### New API version and compatibility guarantees
+
+The 1.0.0 release brings a new API version: **v1beta1**.
+
+Don’t let the name confuse you, we consider v1beta1 the first production ready
API release, and we will maintain backward compatibility for your applications
going forward.
+
+If you are already using the 0.1.0 preview release you can read about the
upgrade process
[here](https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-release-1.0/docs/operations/upgrade/#upgrading-from-v1alpha1---v1beta1),
or check our detailed [compatibility
guarantees](https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-release-1.0/docs/operations/compatibility/).
+
+### Session Job Management
+
+One of the most exciting new features of 1.0.0 is the introduction of the
FlinkSessionJob resource. In contrast with the FlinkDeployment that allows us
to manage Application and Session Clusters, the FlinkSessionJob allows users to
manage Flink jobs on a running Session deployment.
+
+This is extremely valuable in environments where users want to deploy Flink
jobs quickly and iteratively and also allows cluster administrators to manage
the session cluster independently of the running jobs.
+
+Example:
+
+```yaml
+apiVersion: flink.apache.org/v1beta1
+kind: FlinkSessionJob
+metadata:
+ name: basic-session-job-example
+spec:
+ deploymentName: basic-session-cluster
+ job:
+ jarURI:
https://repo1.maven.org/maven2/org/apache/flink/flink-examples-streaming_2.12/1.15.0/flink-examples-streaming_2.12-1.15.0-TopSpeedWindowing.jar
+ parallelism: 4
+ upgradeMode: stateless
+```
+
+### Multi-version Flink support
+
+The Flink Kubernetes Operator now supports the following Flink versions
out-of-the box:
+
+ * Flink 1.15 (Recommended)
+ * Flink 1.14
+ * Flink 1.13
+
+Flink 1.15 comes with a set of features that allow deeper integration for the
operator. We recommend using Flink 1.15 to get the best possible operational
experience.
+
+### Deployment Recovery and Rollbacks
+
+We have added two new features to make Flink cluster operations smoother when
using the operator.
+
+Now the operator will try to recover Flink JobManager deployments that went
missing for some reason. Maybe it was accidentally deleted by the user or
another service in the cluster. As long as HA was enabled and the job did not
fatally fail, the operator will try to restore the job from the latest
available checkpoint.
+
+We also added experimental support for application upgrade rollbacks. With
this feature the operator will monitor new application upgrades and if they
don’t become stable (healthy & running) within a configurable period, they will
be rolled back to the latest stable specification previously deployed.
+
+While this feature will likely see improvements and new settings in the coming
versions, it already provides benefits in cases where we have a large number of
jobs with strong uptime requirements where it’s better to roll back than be
stuck in a failing state.
+
+### Improved Operator Metrics
+
+Beyond the existing JVM based system metrics, additional Operator specific
metrics were added to the current release.
+
+{:class="table table-bordered"}
+| Scope | Metrics | Description
| Type |
+|-----------|--------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------|-------|
+| Namespace | FlinkDeployment.Count | Number of managed
FlinkDeployment instances per namespace
| Gauge |
+| Namespace | FlinkDeployment.<Status>.Count | Number of managed
FlinkDeployment resources per <Status> per namespace. <Status> can
take values from: READY, DEPLOYED_NOT_READY, DEPLOYING, MISSING, ERROR | Gauge |
+| Namespace | FlinkSessionJob.Count | Number of managed
FlinkSessionJob instances per namespace
| Gauge |
+
+## What's Next?
+
+Our intention is to advance further on the [Operator Maturity
Model](https://operatorframework.io/operator-capabilities/) by adding more
dynamic/automatic features
+
+ * Standalone deployment mode support
[FLIP-225](https://cwiki.apache.org/confluence/display/FLINK/FLIP-225%3A+Implement+standalone+mode+support+in+the+kubernetes+operator)
+ * Auto-scaling using Horizontal Pod Autoscaler
+ * Dynamic change of watched namespaces
+ * Pluggable Status and Event reporters (Making it easier to integrate with
proprietary control planes)
+ * SQL jobs support
+
+## Release Resources
+
+The source artifacts and helm chart are now available on the updated
[Downloads](https://flink.apache.org/downloads.html)
+page of the Flink website.
+
+The [official 1.0.0 release
archive](https://archive.apache.org/dist/flink/flink-kubernetes-operator-1.0.0/)
doubles as a Helm repository that you can easily register locally:
+
+{% highlight bash%}
+$ helm repo add flink-kubernetes-operator-1.0.0
https://archive.apache.org/dist/flink/flink-kubernetes-operator-1.0.0/
+$ helm install flink-kubernetes-operator
flink-kubernetes-operator-1.0.0/flink-kubernetes-operator --set
webhook.create=false
+{% endhighlight%}
+
+You can also find official Kubernetes Operator Docker images of the new
version on
[Dockerhub](https://hub.docker.com/r/apache/flink-kubernetes-operator).
+
+For more details, check the [updated
documentation]({{site.DOCS_BASE_URL}}flink-kubernetes-operator-docs-release-1.0/)
and the
+[release
notes](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315522&version=12351500).
+We encourage you to download the release and share your feedback with the
community through the [Flink mailing
lists](https://flink.apache.org/community.html#mailing-lists)
+or
