Overview

[Redis Software version 8.0.10](https://redis.io/downloads/#Redis_Software) is now available! This release includes API enhancements that warranted a new minor version instead of a maintenance release for version 8.0.6. However, you can upgrade from 8.0.2 or 8.0.6 to 8.0.10 without issue.

Highlights

This version offers:

- Redis 8.4 feature set and enhancements

- ARM support for RHEL 9 and Ubuntu 22.04

- Redis Flex operational optimizations during maintenance, scaling, full sync, and shard migration

New in this release

New features

#### Redis 8.4 feature set and enhancements

The Redis 8.4 feature set is now available when you [create]() or [upgrade]() a database with database version 8.4.

Redis 8.4 builds on the foundation of Redis 8.2 with significant enhancements to cluster operations, string manipulation, and stream processing capabilities.

This release delivers major improvements across multiple areas:

- Enhanced string operations with atomic compare-and-set functionality

- Advanced stream processing with idle entry claiming

- Hybrid search capabilities combining multiple ranking algorithms

- High-performance SIMD optimizations for bit operations and vector processing

- Improved JSON handling with better memory efficiency

- See [What's new in Redis 8.4]() and [Redis Open Source 8.4 release notes]() for more details.

#### Redis Flex operational optimizations

Redis Flex databases running on Redis 8.4 have major operational optimizations:

- Scaling is 2x faster, cutting the duration of scaling in half.

- A new internal replication mechanism:

    - Enables 10x faster full sync operations, where an entire shard is replicated across nodes. Operations such as maintenance, shard migration, recovery from node failure, and upgrades are now up to 10x faster than before.

    - Enables shorter copy-on-write (CoW), which lowers peak memory usage, reduces latency jitter, and improves write throughput during persistence.

#### ARM support for RHEL 9 and Ubuntu 22.04

Redis Software now supports ARM architecture on RHEL 9 and Ubuntu 22.04, enabling deployments on cost-efficient, high-performance ARM-based servers.

Enhancements

- Added support for database name labels in v2 metrics when the `metrics_exporter_expose_bdb_name` cluster policy setting is enabled:

    [code example]

- Added new v2 metrics for monitoring the health of shards, the DMC, and endpoints:

    - shard_ping_failures

    - shard_ping_failure_duration_seconds

    - dmc_ping_failures

    - dmc_ping_failure_duration_seconds

    - endpoint_ping_failures

    - endpoint_ping_failure_duration_seconds

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](https://github.com/redis/redis/releases) available with [Redis Open Source](https://github.com/redis/redis). 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 8.0.10-64 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.

Redis Software release notes 8.0.16-29 (March 2026)

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

Overview

[Redis Software version 8.0.16](https://redis.io/downloads/#Redis_Software) 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]():

    [code example]

- [Database health report]():

    [code example]

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.

Applying global configuration changes will override any local settings created using the API or earlier Cluster Manager UI versions. To preserve existing local changes, manage them in the **Local** configuration tab before applying global changes.

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:

    [code example]

- 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.

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.

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](https://github.com/redis/redis/releases) available with [Redis Open Source](https://github.com/redis/redis). 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.
