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.
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">}}).
The following changes included in this release affect the upgrade process. Please read carefully before upgrading.
{{<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>}}
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).
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.
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.
