+[`pgo` CLI documentation]: https://access.crunchydata.com/documentation/postgres-operator-client/latest
+
+Crunchy Data announces the release of `pgo`, Postgres Operator Client from Crunchy Data 0.4.0.
+
+Built as a `kubectl` plugin, the `pgo` CLI facilitates the creation and management of PostgreSQL clusters created using [Crunchy Postgres for Kubernetes][].
+
+For more information about using the CLI and the various commands available, please see the [`pgo` CLI documentation][].
+
+Additionally, please see the [CPK documentation](https://access.crunchydata.com/documentation/postgres-operator/latest) for information about [getting started](https://access.crunchydata.com/documentation/postgres-operator/latest/quickstart/) with Crunchy Postgres for Kubernetes.
+
+## Features
+- The new `start` and `stop` commands now allow the user to shutdown and restart a PostgresCluster.
+- The new `show ha` subcommand gets information (e.g., replication lag and more) from the High Availability system about a PostgresCluster's members.
+- The new `show user` subcommand gets information on users created through the PostgresCluster spec and can be used to get connection info.
+- The `show` command now can be used to show the combined outputs of the `show backup` and `show ha` subcommands.
+- The `create postgrescluster` command can now be used to create a PostgresCluster with any version of Postgres supported by Crunchy Postgres for Kubernetes.
+
+## Changes
+
+- The Support Export command now stores logs in a single directory.
+- The Support Export command now records kubectl plugins installed on the client workstation.
+- The Support Export command now records the result of `pgbackrest info` to help debug issues related to backups.
+- The Support Export command now records a list naming all reachable PostgresClusters and their namespaces.
+- The Support Export command now records the system time reported from each labeled container as compared to the system time of the client workstation to debug time drift.
+- The Backup and Restore commands now include a `--force-conflicts` flag, making it possible to overwrite backup and restore settings when there’s an ownership conflict.
