Redis Software release notes 8.0.16-29 (March 2026)

Consolidated health report. Global Active-Active configuration in the Cluster Manager UI.

​​Redis Software version 8.0.16 is now available! This release includes API enhancements that warranted a new minor version instead of a maintenance release for version 8.0.10. However, you can upgrade from 8.0.2, 8.0.6, or 8.0.10 to 8.0.16 without issue.

Highlights

This version offers:

• Consolidated health report

• Global Active-Active configuration in the Cluster Manager UI

New in this release

New features

Consolidated health report

Redis Software's new health report is a read-only, consolidated snapshot of a cluster's current system health, including:

• License and certificate status

• Nodes and services health

• Node memory breakdown, including free and provisioned memory

• Running actions status

• Active alerts

• Basic database status and version

• High availability health

The new health report consolidates cluster and database health information that was previously scattered across multiple APIs and CLI commands, such as rladmin status extra all and required SSH access to view.

Now, you can access the cluster and database health reports using the Overview screen in the Cluster manager UI or the new health API paths:

• Cluster health report:

  GET /v4/cluster/health
  

• Database health report:

  GET /v4/bdb/<database_id>/health
  

For more information, see Consolidated health report.

Global Active-Active configuration in the Cluster Manager UI

The Cluster Manager UI now supports global configuration updates for Active-Active databases, bringing UI behavior in line with the CRDB API.

Previously, when modifying Active-Active databases using the CRDB API, configuration changes were applied globally by default. However, when performing the same actions in the Cluster Manager UI, modifications applied only to the local instance, requiring additional manual updates for each instance in participating clusters.

Global configuration is now the default in the Cluster Manager UI. You can still make local configuration changes when needed, which will override global settings on the database instances where they are applied.

For more information, see Manage Active-Active databases.

Enhancements

• Added the ability to undo configuration overrides for an Active-Active database instance and reset it to the default database configuration using a REST API request to update an Active-Active database. For example:

  PATCH /v1/crdbs/<crdb_guid>
  { "instances": [{
      "db_uid": "<local_database_instance_id>",
      "id": <instance_id>,
      "db_config": { "<overridden_field_name>": null }
    }
  ]}
  

• For smart client handoffs, the delay between notifying clients and performing an operation is now configurable using the new state_machine_smart_client_handoffs_delay_ms cluster setting in the REST API.

Redis database versions

Redis Software version 8.0.16 includes the following Redis database versions: 8.4.0, 8.2.1, 8.0.2, 7.4.3, 7.2.7, and 6.2.13.

The default Redis database version is 8.4.

Redis feature sets

Redis 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

• RS168233: Fixed an issue where Active-Active database instance removal could fail with authentication errors if the default database password was enabled during database creation and deactivated after creation.

• RS150707: Fixed an issue where endpoint binding operations could become stuck if a node restarted during the binding process.

• RS176558: Fixed a misleading error message that mentioned LDAP service problems when authentication issues occurred with Entra ID.

• RS160689: Fixed an issue where redis-cli INFO could temporarily show an outdated data eviction policy after changing the policy in the Cluster Manager UI.

• RS171340: Fixed an issue where install.sh would continue running even when required ports were already occupied.

• RS171806: Fixed an issue where the rladmin cluster running_actions command could fail when active tasks did not have progress information available.

• RS184175: Fixed an issue where active cluster alerts were not properly displayed in health reports.

• RS128780: Reduced excessive logging by removing unnecessary "Dropping obsolete sample" message from the CCS log file.

• RS185428: Improved error messages for missing root or chain of trust issues during certificate upload.

• RS180061: Fixed an issue where user password update REST API requests would fail if the new password matched the current password.

• RS176555: Fixed an issue that could cause the DMC to crash if a client disconnected during the authentication process.

• RS167847: Fixed an issue where turning off alert_mgr also turned off event_log.

• RS182007: Modified the custom installer script to prevent the creation of circular symlinks during cluster upgrades.

• RS188362: Fixed an issue with missing metrics in the Cluster Manager UI.

• RS189517: Fixed a breaking change where LDAP filters for user_dn_query and dn_group_query strictly required parentheses to function correctly. This change caused filters that previously worked without parentheses to stop working after upgrading to Redis Software version 8.0.x. As of version 8.0.16, this breaking change no longer applies, and both (sAMAccountName=%u) and sAMAccountName=%u are valid filters.

Version changes

Breaking changes

• Upgrading to this Redis Software version can cause LDAP authentication to fail with "certificate signed by unknown authority" errors if your cluster currently uses LDAP authentication. This issue will be fixed in an upcoming maintenance release.

Deprecations

API deprecations

• Deprecated event_archive_cleanup_task_settings for job_scheduler REST API requests.

Supported platforms

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

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

⚠️ Deprecation warning – The platform is still supported for this version of Redis 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 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

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

Known limitations

Trim ACKED not supported for Active-Active 8.4 databases

For Active-Active databases running Redis database version 8.4, the ACKED option is not supported for trimming commands.

Rolling upgrade limitation for clusters with custom or deprecated modules

Due to module handling changes introduced in Redis 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 Software implements the latest security fixes available with Redis Open Source. Redis Software has already included the fixes for the relevant CVEs.

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

Redis Software 8.0.16-29 supports Redis Open Source 8.4, 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.
