## Highlights

The primary purpose of this release is to support [Redis Enterprise 7.4.2]({{< relref "/operate/rs/release-notes/rs-7-4-2-releases/rs-7-4-2-104" >}}), which is a maintenance release of Redis Enterprise Software.

## Version changes

For a list of fixes related to CVEs, see the [Redis Enterprise 7.4.2-104 release notes]({{<relref "operate/rs/release-notes/rs-7-4-2-releases/rs-7-4-2-104#security">}}).

### Breaking changes

The following changes included in this release affect the upgrade process. Please read carefully before upgrading.

#### Upgrade operating system

{{<warning>}}If your databases use modules, you need to update all nodes in the cluster to Redis Enterprise 7.2.4 or later before upgrading your operating system. See [Upgrade a cluster's operating system]({{< relref "/operate/rs/installing-upgrading/upgrading/upgrade-os" >}})in the Redis Enterprise Software documentation for more details.{{</warning>}}

#### terminationGracePeriodSeconds

The configurable `terminationGracePeriodSeconds` REC field was added in version 7.2.4-12 to replace the hard-coded timeout of 15 minutes for a node to be stopped or drained (RED-111471).

#### ValidatingWebhookConfiguration

Versions 6.4.2-4 and later include a new `ValidatingWebhookConfiguration` resource to replace the `redb-admission` webhook resource. To use releases 6.4.2-4 or later, delete the old webhook resource and apply the new file. See [upgrade Redis cluster]({{< relref "/operate/kubernetes/upgrade/upgrade-redis-cluster#reapply-webhook" >}}) for instructions.

#### OpenShift SCC

Versions 6.4.2-6 and later include a new SCC (`redis-enterprise-scc-v2`) that you need to bind to your service account before upgrading. OpenShift clusters running version 6.2.12 or earlier upgrading to version 6.2.18 or later might get stuck if you skip this step. See [upgrade a Redis Enterprise cluster (REC)]({{< relref "/operate/kubernetes/upgrade/upgrade-redis-cluster#before-upgrading" >}}) for instructions.

### Deprecations

- Redis Software for Kubernetes no longer supports the RHEL7 operating system. Migrate to RHEL8 to use this version.
