Redis Enterprise Software release notes 8.0.6-54 (December 2025)

Single sign-on for the Cluster Manager UI. Error reports for Replica Of migration status. Automatically download and install user-defined modules during bootstrapping.

​​Redis Enterprise Software version 8.0.6 is now available! This release includes API enhancements that warranted a new minor version instead of a maintenance release for version 8.0.2. However, you can upgrade from 8.0.2 to 8.0.6 without issue.

Highlights

This version offers:

• Single sign-on for the Cluster Manager UI

• Error reports for Replica Of migration status

• Automatically download and install user-defined modules during bootstrapping

New in this release

New features

Single sign-on for the Cluster Manager UI

Redis Enterprise Software now supports IdP-initiated and SP-initiated single sign-on (SSO) with SAML (Security Assertion Markup Language) 2.0 for the Cluster Manager UI.

When SSO is activated:

• Users can sign in to the Redis Enterprise Software Cluster Manager UI using their identity provider (IdP) instead of usernames and passwords.

• Optionally, you can enforce SSO for the cluster, which means non-admin users can no longer sign in with their previous usernames and passwords and must use SSO instead.

• With just-in-time (JIT) user provisioning, Redis Enterprise Software automatically creates a user account the first time a new user signs in with SSO.

For more information and setup instructions, see SAML single sign-on.

Known limitation: You cannot change the default service provider address using the Cluster Manager UI. You can only change this address using a REST API request.

Enhancements

• Added error report to Replica Of migration status REST API responses.

• Added support for automatically downloading and installing user-defined modules during bootstrap operations. You can now specify user_defined_modules in bootstrap requests for create_cluster, join_cluster, and recover_cluster actions. See Add user-defined modules during bootstrapping for details.

• Added cert and private_key fields to the CRDB database config object for an optional PEM-encoded server certificate for the underlying database instance.

Redis database versions

Redis Enterprise Software version 8.0.6 includes five Redis database versions: 8.2.1, 8.0.2, 7.4.3, 7.2.7, and 6.2.13.

The default Redis database version is 8.2.

Redis feature sets

Redis Enterprise Software includes multiple feature sets, compatible with different Redis database versions.

The following table shows which Redis modules are compatible with each Redis database version included in this release.

Resolved issues

• RS131972: Fixed an issue where creating an ACL that contains a line break in the Cluster Manager UI could cause shard migration to fail due to ACL errors.

• RS140424: Fixed an issue where configuration changes initiated topology updates even if the topology did not change.

• RS144636: Improved support package generation to collect available database information even when some data collection steps fail.

• RS162503: Fixed an issue where force-removed Active-Active database instances could not be re-added as participating members without purging.

• RS155782: Improved logs and added validation to ensure operations are properly queued and prevent stuck state machines.

• RS167151: Improved reliability of node removal operations by increasing retry attempts for failover and reshard operations.

• RS167280: Fixed an issue where a subset of shards on a restarted node could fail to start due to temporary connection issues.

• RS172813: Improved logging for Active-Active database failover scenarios to provide better visibility into data recovery processes.

• RS173195: Fixed an issue where cluster operations could fail when attempting to communicate with unreachable nodes.

• RS174154: Fixed an issue where EntraID authentication service was not properly enabled despite being configured and running.

• RS174819: Fixed an issue where duplicate syncers could spawn on the same node.

• RS176400: Fixed an issue where Google Cloud Storage backup locations could be set to the incorrect type when configured in the Cluster Manager UI.

• RS165983: Fixed an issue where an incorrect value was printed for region_name in the event log.

Version changes

Supported platforms

The following table provides a snapshot of supported platforms as of this Redis Enterprise Software release. See the supported platforms reference for more details about operating system compatibility.

✅ Supported – The platform is supported for this version of Redis Enterprise Software and Redis Stack modules.

⚠️ Deprecation warning – The platform is still supported for this version of Redis Enterprise Software, but support will be removed in a future release.

1. The RHEL-compatible distributions CentOS, CentOS Stream, Alma, and Rocky are supported if they have full RHEL compatibility. Oracle Linux running the Red Hat Compatible Kernel (RHCK) is supported, but the Unbreakable Enterprise Kernel (UEK) is not supported.

2. The server version of Ubuntu is recommended for production installations. The desktop version is only recommended for development deployments.

3. See the Redis Enterprise for Kubernetes documentation for details about support per version and Kubernetes distribution.

4. Docker images of Redis Enterprise Software are certified for development and testing only.

5. Supported only if FIPS was enabled during RHEL installation to ensure FIPS compliance.

Downloads

The following table shows the SHA256 checksums for the available packages:

Known issues

• RS180550: You cannot set up SSO when the Cluster Manager UI is exposed through an IPv6-based load balancer or gateway.

  As a workaround, use an IPv4-based address for the SSO service base address, or register a DNS name that resolves to the IPv6 address.

• RS155734: Endpoint availability metrics do not work as expected due to a calculation error.

Known limitations

Cannot change SP address for SSO in the Cluster Manager UI

You cannot change the default service provider address using the Cluster Manager UI. You can only change this address using a REST API request.

Rolling upgrade limitation for clusters with custom or deprecated modules

Due to module handling changes introduced in Redis Enterprise Software version 8.0, upgrading a cluster that contains custom or deprecated modules, such as RedisGraph and RedisGears v2, can become stuck when adding a new node to the cluster during a rolling upgrade.

Module commands limitation during Active-Active database upgrades to Redis 8.0

When upgrading an Active-Active database to Redis version 8.0, you cannot use module commands until all Active-Active database instances have been upgraded. Currently, these commands are not blocked automatically.

Redis 8.0 database cannot be created with flash

You cannot create a Redis 8.0 database with flash storage enabled. Create a Redis 8.0 database with RAM-only storage instead, or use Redis 8.2 for flash-enabled (Redis Flex) databases.

Cluster Manager UI limitations

The following legacy UI features are not yet available in the new Cluster Manager UI:

• Purge an Active-Active instance.

  Use crdb-cli crdb purge-instance instead.

• Search and export the log.

Security

Redis Open Source security fixes compatibility

As part of Redis's commitment to security, Redis Enterprise Software implements the latest security fixes available with Redis Open Source. Redis Enterprise Software has already included the fixes for the relevant CVEs.

Some CVEs announced for Redis Open Source do not affect Redis Enterprise Software due to different or additional functionality available in Redis Enterprise Software that is not available in Redis Open Source.

Redis Enterprise Software 8.0.6-54 supports Redis Open Source 8.2, 8.0, 7.4, 7.2, and 6.2. Below is the list of Redis Open Source CVEs and other security vulnerabilities fixed by version.
