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

#### 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]() 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)]() for instructions.

#### Upcoming Changes

- Future Redis Enterprise images will be UBI9-based only, without support for Ubuntu-based images.

title: New limitations

text:
- **Missing endpoint for admission endpoint (rare) (RED-119469)** Restart the operator pod.

- **PVC expansion is not supported when using Redis on Flash (Auto Tiering) (RED-165770)** Do not enable `enablePersistentVolumeResize` if your REC uses `redisOnFlashSpec` as this will result in conflicts.

title: Existing limitations

text:
- **The REDB "redisVersion" field can’t be used for memcached databases(RED-119152)**

- **When modifying the database suffix for an Active-Active database, while the service-rigger is in a terminating state, the services-rigger will delete and create the ingress or route resources in a loop (RED-107687)** Wait until the services rigger pod has finished to terminate it.

- **REAADB changes might fail with "gateway timeout" errors, mostly on OpenShift (RED-103048)** Retry the operation.

- **Creating two databases with the same name directly on Redis Enterprise software will cause the service to be deleted and the database will not be available (RED-99997)** Avoid duplicating database names. Database creation via K8s has validation in place to prevent this.

- **Installing the operator bundle produces warning: `Warning: would violate PodSecurity "restricted: v1.24"` (RED-97381)** Ignore the warning. This issue is documented as benign on official Red Hat documentation.

- **RERC resources must have a unique name (RED-96302)** The string "rec-name"/"rec-namespace" must be different from all other participating clusters in the Active-Active database.

- **Admission is not blocking REAADB with `shardCount` which exceeds license quota (RED-96301)** Fix the problems with the REAADB and reapply.

- **Active-Active controller only supports global database options. Configuration specific to location is not supported (RED-86490)**

- **Active-Active setup removal might keep services or routes undeleted (RED-77752)** Delete services or routes manually if you encounter this problem.

- **`autoUpgrade` set to `true` can cause unexpected bdb upgrades when `redisUpgradePolicy` is set to `true` (RED-72351)** Contact support if your deployment is impacted.

- **Following the previous quick start guide version causes issues with creating an REDB due to unrecognized memory field name (RED-69515)** The workaround is to use the newer (current) revision of Deploy Redis Enterprise Software for Kubernetes.

- **PVC size issues when using decimal value in spec (RED-62132)** Make sure you use integer values for the PVC size.

- **REC might report error states on initial startup (RED-61707)** There is no workaround at this time except to ignore the errors.

- **Hashicorp Vault integration - no support for Gesher (RED-55080)** There is no workaround for this issue. Gesher support has been deprecated.

- **REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED-47254)** When REC clusters are deployed on Kubernetes clusters without synchronized clocks, the REC cluster does not start correctly. The fix is to use NTP to synchronize the underlying K8s nodes.

- **Deleting an OpenShift project with an REC deployed may hang (RED-47192)** When an REC cluster is deployed in a project (namespace) and has REDB resources, the REDB resources must be deleted first before the REC can be deleted. Therefore, until the REDB resources are deleted, the project deletion will hang. The fix is to delete the REDB resources first and the REC second. Then, you can delete the project.

- **Clusters must be named 'rec' in OLM-based deployments (RED-39825)** In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec".

- **Readiness probe incorrect on failures (RED-39300)** STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.

- **Internal DNS and Kubernetes DNS may have conflicts (RED-37462)** DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.

- **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to latest version.

- **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.

- **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

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

#### Upgrade operating system

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]()in the Redis Enterprise Software documentation for more details.

#### 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]() 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)]() for instructions.

- **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to latest version.

- **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.

- **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

title: Detailed release notes

title: Breaking changes

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

title: ValidatingWebhookConfiguration

text: 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]() for instructions.

title: OpenShift SCC

text: 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. If you skip this step, OpenShift clusters running version 6.2.12 or earlier might get stuck when upgrading to version 6.2.18 or later. See [upgrade a Redis Enterprise cluster (REC)]() for instructions.

title: Upcoming Changes

text: - Future Redis Enterprise images will be UBI9-based only, without support for Ubuntu-based images.

title: Security

role: security

text: For a list of fixes related to CVEs, see the [Redis Enterprise 7.2.4-109 release notes]().

title: Known limitations

text:
- **Missing endpoint for admission endpoint (rare) (RED-119469)** Restart the operator pod.

- **The REDB "redisVersion" field can’t be used for memcached databases(RED-119152)**

- **When modifying the database suffix for an Active-Active database, while the service-rigger is in a terminating state, the services-rigger will delete and create the ingress or route resources in a loop (RED-107687)** Wait until the services rigger pod has finished to terminate it.

- **REAADB changes might fail with "gateway timeout" errors, mostly on OpenShift (RED-103048)** Retry the operation.

- **Creating two databases with the same name directly on Redis Enterprise software will cause the service to be deleted and the database will not be available (RED-99997)** Avoid duplicating database names. Database creation via K8s has validation in place to prevent this.

- **Installing the operator bundle produces warning: `Warning: would violate PodSecurity "restricted: v1.24"` (RED-97381)** Ignore the warning. This issue is documented as benign on official Red Hat documentation.

- **RERC resources must have a unique name (RED-96302)** The string "rec-name"/"rec-namespace" must be different from all other participating clusters in the Active-Active database.

- **Admission is not blocking REAADB with `shardCount` which exceeds license quota (RED-96301)** Fix the problems with the REAADB and reapply.

- **Active-Active controller only supports global database options. Configuration specific to location is not supported (RED-86490)**

- **Active-Active setup removal might keep services or routes undeleted (RED-77752)** Delete services or routes manually if you encounter this problem.

- **`autoUpgrade` set to `true` can cause unexpected bdb upgrades when `redisUpgradePolicy` is set to `true` (RED-72351)** Contact support if your deployment is impacted.

- **Following the previous quick start guide version causes issues with creating an REDB due to unrecognized memory field name (RED-69515)** The workaround is to use the newer (current) revision of Deploy Redis Enterprise Software for Kubernetes.

- **PVC size issues when using decimal value in spec (RED-62132)** Make sure you use integer values for the PVC size.

- **REC might report error states on initial startup (RED-61707)** There is no workaround at this time except to ignore the errors.

- **Hashicorp Vault integration - no support for Gesher (RED-55080)** There is no workaround for this issue. Gesher support has been deprecated.

- **REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED-47254)** When REC clusters are deployed on Kubernetes clusters without synchronized clocks, the REC cluster does not start correctly. The fix is to use NTP to synchronize the underlying K8s nodes.

- **Deleting an OpenShift project with an REC deployed may hang (RED-47192)** When an REC cluster is deployed in a project (namespace) and has REDB resources, the REDB resources must be deleted first before the REC can be deleted. Therefore, until the REDB resources are deleted, the project deletion will hang. The fix is to delete the REDB resources first and the REC second. Then, you can delete the project.

- **Clusters must be named 'rec' in OLM-based deployments (RED-39825)** In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec".

- **Readiness probe incorrect on failures (RED-39300)** STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.

- **Internal DNS and Kubernetes DNS may have conflicts (RED-37462)** DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.

- **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to latest version.

- **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.

- **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

title: Detailed release notes

title: Breaking changes

title: RHEL9-based images

text:
- As of version 7.8.2-6, Redis Enterprise images are based on Red Hat Enterprise Linux 9 (RHEL9). This means upgrades to 7.8.2-6 require:

- Cluster version of 7.4.2-2 or later.
- Database version 7.2 or later.
- RHEL9 compatible binaries for any modules you need.

See [Upgrade Redis Enterprise for Kubernetes]() for detailed steps to upgrade to 7.8.4-8.

title: Deprecations

text:
- Ubuntu-based images are no longer supported.
- REDB field `upgradeSpec.upgradeModulesToLatest is deprecated.
- REDB field `spec.modulesList.version` is deprecated.

title: Known limitations

title: New limitations

text: - **Specifying `databasePort` causes issues with REAADB synchronization. (RED-149374)**

title: Existing limitations

text:
- **Only upgrades from 7.4.2-2 and later are supported.** If you are using an earlier version, install 7.4.2-2 before upgrading to 7.8.2-6 or later.

- **When changing the REDB field `spec.modulesList`, version might be upgraded to latest, even if a different version is specified.** To prevent the upgrade to latest, set  `spec.upgradeSpec.setModuleToLatest` to `false` before upgrading to 7.8.2-6.

- **Missing endpoint for admission endpoint (rare) (RED-119469)** Restart the operator pod.

- **The REDB "redisVersion" field can’t be used for memcached databases(RED-119152)**

- **When modifying the database suffix for an Active-Active database, while the service-rigger is in a terminating state, the services-rigger will delete and create the ingress or route resources in a loop (RED-107687)** Wait until the services rigger pod has finished to terminate it.

- **REAADB changes might fail with "gateway timeout" errors, mostly on OpenShift (RED-103048)** Retry the operation.

- **Creating two databases with the same name directly on Redis Enterprise software will cause the service to be deleted and the database will not be available (RED-99997)** Avoid duplicating database names. Database creation via K8s has validation in place to prevent this.

- **Installing the operator bundle produces warning: `Warning: would violate PodSecurity "restricted: v1.24"` (RED-97381)** Ignore the warning. This issue is documented as benign on official Red Hat documentation.

- **RERC resources must have a unique name (RED-96302)** The string "rec-name"/"rec-namespace" must be different from all other participating clusters in the Active-Active database.

- **Admission is not blocking REAADB with `shardCount` which exceeds license quota (RED-96301)** Fix the problems with the REAADB and reapply.

- **Active-Active controller only supports global database options. Configuration specific to location is not supported (RED-86490)**

- **Active-Active setup removal might keep services or routes undeleted (RED-77752)** Delete services or routes manually if you encounter this problem.

- **`autoUpgrade` set to `true` can cause unexpected bdb upgrades when `redisUpgradePolicy` is set to `true` (RED-72351)** Contact support if your deployment is impacted.

- **Following the previous quick start guide version causes issues with creating an REDB due to unrecognized memory field name (RED-69515)** The workaround is to use the newer (current) revision of Deploy Redis Enterprise Software for Kubernetes.

- **PVC size issues when using decimal value in spec (RED-62132)** Make sure you use integer values for the PVC size.

- **REC might report error states on initial startup (RED-61707)** There is no workaround at this time except to ignore the errors.

- **Hashicorp Vault integration - no support for Gesher (RED-55080)** There is no workaround for this issue. Gesher support has been deprecated.

- **REC clusters fail to start on Kubernetes clusters with unsynchronized clocks (RED-47254)** When REC clusters are deployed on Kubernetes clusters without synchronized clocks, the REC cluster does not start correctly. The fix is to use NTP to synchronize the underlying K8s nodes.

- **Deleting an OpenShift project with an REC deployed may hang (RED-47192)** When an REC cluster is deployed in a project (namespace) and has REDB resources, the REDB resources must be deleted first before the REC can be deleted. Therefore, until the REDB resources are deleted, the project deletion will hang. The fix is to delete the REDB resources first and the REC second. Then, you can delete the project.

- **Clusters must be named 'rec' in OLM-based deployments (RED-39825)** In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec".

- **Readiness probe incorrect on failures (RED-39300)** STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.

- **Internal DNS and Kubernetes DNS may have conflicts (RED-37462)** DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.

- **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to latest version.

- **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.

- **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

title: API changes

text:
| **CRD** | **Field** | **Change** | **Description** |
|---|---|---|---|
| REAADB | `spec.externalReplicationPort` | ADD | Specifies the replication endpoint port number for users who use LoadBalancers to synchronize Active-Active replicas and must provide the port that the LoadBalancer listens on. |
| REC | `status.shardsUsage` | ADD | Total number of shards (both RAM and flash) currently in use under this license. |
| REC | `status.flashShards` | ADD | Number of flash shards currently in use under this license. |
| REC | `status.flashShardsLimit` | ADD | Number of flash shards allowed under this license. |
| REC | `status.ramShards` | ADD | Number of RAM shards currently in use under this license. |
| REC | `status.ramShardsLimit` | ADD | Number of RAM shards allowed under this license. |
| REC | `spec.podSecurityPolicyName` | REMOVE | Not supported anymore by supported Kubernetes versions. |
| REC | `spec.databaseServicePortPolicy` | ADD | Specifies how to determine service ports for REDB services. Defaults to DatabasePortForward if not set. DatabasePortForward - The service port will be the same as the database port. RedisDefaultPort - The service port will be the default Redis port (6379).

title: Breaking changes

text: Customers who use load balancers for Active-Active replication endpoints and rely on the change introduced in RED-113626 (or the workaround described in the ticket) must set the spec.externalReplicationPort field in REAADB after upgrading. Otherwise, replication will fail (RED-149374).

Therefore, until the REDB resources are deleted, the project deletion will hang. The fix is to delete the REDB resources first and the REC second. Then, you can delete the project.

- **Clusters must be named 'rec' in OLM-based deployments (RED-39825)** In OLM-deployed operators, the deployment of the cluster will fail if the name is not "rec". When the operator is deployed via the OLM, the security context constraints (scc) are bound to a specific service account name (namely, "rec"). The workaround is to name the cluster "rec".

- **Readiness probe incorrect on failures (RED-39300)** STS Readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.

- **Internal DNS and Kubernetes DNS may have conflicts (RED-37462)** DNS conflicts are possible between the cluster `mdns_server` and the K8s DNS. This only impacts DNS resolution from within cluster nodes for Kubernetes DNS names.

- **K8s-based 5.4.10 clusters seem to negatively affect existing 5.4.6 clusters (RED-37233)** Upgrade clusters to latest version.

- **Node CPU usage is reported instead of pod CPU usage (RED-36884)** In Kubernetes, the reported node CPU usage is the usage of the Kubernetes worker node hosting the REC pod.

- **An unreachable cluster has status running (RED-32805)** When a cluster is in an unreachable state, the state remains `running` instead of triggering an error.

- **Long cluster names cause routes to be rejected  (RED-25871)** A cluster name longer than 20 characters will result in a rejected route configuration because the host part of the domain name exceeds 63 characters. The workaround is to limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates (RED-25542)** A cluster CR specification error is not reported if two or more invalid CR resources are updated in sequence.

summary: Feature release with OSS Cluster API support for external clients, ARM architecture support, and Redis Software 8.0.10-64.

title: Overview

text:
Redis Enterprise for Kubernetes 8.0.10-21 is a feature release that supports [Redis Software 8.0.10-64
]() and includes new features and enhancements.

title: Highlights

text:
- OSS Cluster API support for external clients
- ARM architecture support
- Redis Software 8.0.10-64 support

title: Enhancements

text:
- Added OSS Cluster API support for external clients <!--RED-51898-->
- Added ARM architecture support <!--RED-164742-->
- Added Vault secret support for user-defined modules <!--RED-178449-->
- Added `extraLabels` injection to resources created by the services rigger <!--RED-180274-->
- Added `clusterCredentialSecretName` customization with Kubernetes secrets <!--RED-180513-->
- REC username default value now derives from the cluster credentials secret <!--RED-180515-->
- Added Kubernetes 1.35 support on select platforms <!--RED-181443-->

When you pull images from container registries such as Docker Hub, ARM support is transparent. The registry automatically serves the correct image based on the node architecture (AMD64 or ARM64).

title: Resolved issues

text:
- Fixed invalid `containerStatuses` indexing caused by incorrect order assumption <!--RED-175259-->
- Removed unnecessary update calls from the services rigger to load balancers <!--RED-176881-->
- Fixed multiple security issues

title: API changes

text:
| **CRD** | **Field** | **Change** | **Description** |
|---|---|---|---|
| REDB | `spec.ossClusterSettings` | Added | Additional OSS cluster mode settings. |
| REDB | `spec.ossClusterSettings.enableExternalAccess` | Added | Toggles whether this database supports external access in OSS cluster mode. When enabled, advertised database topology includes the external endpoints for the Redis Enterprise nodes hosting the database shards. The external access mechanism (such as LoadBalancer services) is configured using the `ossClusterSettings.externalAccessType` field of the RedisEnterpriseCluster. When external access is enabled, the corresponding database secret will have the list of primary shard IPs in the `oss_startup_nodes` field. |

title: Known limitations

title: New limitations

text: - **SSO configuration does not work with IPv6 or dual-stack (IPv4/IPv6) clusters.** <!--RED-180550-->

title: Existing limitations

text:
- **Upgrades from versions earlier than 7.4.2-2 are not supported.** If you use an earlier version, upgrade to 7.4.2-2 before upgrading to 8.0.10-21.

- **Missing endpoint for admission endpoint (rare). (RED-119469)** Restart the operator pod.

- **The REDB `redisVersion` field cannot be used for memcached databases. (RED-119152)**

- **Modifying the database suffix for an Active-Active database while the services rigger is terminating causes a loop. (RED-107687)** The services rigger deletes and recreates ingress or route resources repeatedly. Wait for the services rigger pod to finish terminating before modifying the suffix.

- **REAADB changes might fail with "gateway timeout" errors, especially on OpenShift. (RED-103048)** Retry the operation.

- **Creating two databases with the same name in the Redis Enterprise Cluster Manager UI deletes the service and makes the database unavailable. (RED-99997)** Avoid duplicate database names. The admission controller prevents duplicate names when you create databases through the Kubernetes operator.

- **Installing the operator bundle produces the warning `Warning: would violate PodSecurity "restricted: v1.24"`. (RED-97381)** Ignore this warning. Red Hat documentation identifies this issue as benign.

- **RERC resources must have a unique name. (RED-96302)** The `rec-name/rec-namespace` string must differ from all other participating clusters in the Active-Active database.

- **Admission does not block REAADB resources with a `shardCount` that exceeds the license quota. (RED-96301)** Correct the REAADB configuration and reapply.

- **The Active-Active controller supports only global database options. (RED-86490)** Location-specific configuration is not supported.

- **Removing an Active-Active setup might leave services or routes undeleted. (RED-77752)** Delete the services or routes manually.

- **Setting `autoUpgrade` to `true` can cause unexpected database upgrades when `redisUpgradePolicy` is also `true`. (RED-72351)** Contact support if your deployment is affected.

- **Using the previous quick start guide causes REDB creation issues due to an unrecognized memory field name. (RED-69515)** Use the current version of the Deploy Redis Enterprise Software for Kubernetes guide.

- **PVC size does not work with decimal values. (RED-62132)** Use integer values for the PVC size.

- **REC might report error states on initial startup. (RED-61707)** No workaround exists. Ignore the errors.

- **HashiCorp Vault integration does not support Gesher. (RED-55080)** No workaround exists. Gesher support is deprecated.

- **REC clusters fail to start on Kubernetes clusters with unsynchronized clocks. (RED-47254)** Use NTP to synchronize the underlying Kubernetes nodes.

- **Deleting an OpenShift project with a deployed REC might hang. (RED-47192)** When an REC cluster is deployed in a project (namespace) with REDB resources, you must delete the REDB resources before deleting the REC. The project deletion hangs until you delete the REDB resources. Delete the REDB resources first, then delete the REC, and then delete the project.

- **Clusters must be named "rec" in OLM-based deployments. (RED-39825)** When you deploy the operator through OLM, the security context constraints (SCC) are bound to a specific service account name ("rec"). The deployment fails if the cluster has a different name.

- **Readiness probe does not correctly report failures. (RED-39300)** The StatefulSet readiness probe does not mark a node as "not ready" when running `rladmin status` on node failure.

- **Internal DNS and Kubernetes DNS might conflict. (RED-37462)** DNS conflicts can occur between the cluster `mdns_server` and Kubernetes DNS. This affects only DNS resolution from within cluster nodes for Kubernetes DNS names.

- **Kubernetes-based 5.4.10 clusters might negatively affect existing 5.4.6 clusters. (RED-37233)** Upgrade your clusters to the latest version.

- **Node CPU usage is reported instead of pod CPU usage. (RED-36884)** The reported CPU usage is for the Kubernetes worker node hosting the REC pod, not the pod itself.

- **An unreachable cluster shows status as running. (RED-32805)** When a cluster is unreachable, the status remains `running` instead of showing an error.

- **Long cluster names cause routes to be rejected. (RED-25871)** A cluster name longer than 20 characters causes route rejection because the host part of the domain name exceeds 63 characters. Limit the cluster name to 20 characters or fewer.

- **Cluster CR (REC) errors are not reported after invalid updates. (RED-25542)** A cluster CR specification error is not reported if you update two or more invalid CR resources in sequence.
