​​Redis Software version 8.0.10 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:

  PUT /v1/cluster/policy
  { "metrics_exporter_expose_bdb_name": true }
  

• 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

Redis database versions

Redis Software version 8.0.10 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

• RS124443: Fixed an error that could occur during fresh installations when attempting to set file permissions before the redislabs user and group were created.

• RS147692: Fixed an issue with persistence configuration and storage path handling where persistence could fail after temporary storage disruptions.

• RS160493: Improved reliability of failover operations by enhancing retry mechanisms and connection handling.

• RS161545: Fixed an issue in two-node clusters with witness disk where a freeze of the primary node could lead to a split-brain scenario where both nodes believe they are the primary node, leading to cluster instability.

• RS162828: Fixed an issue where database authentication could fail after ACL changes due to outdated access control configurations.

• RS165065: Fixed an issue with configuration updates on promoted shards after failover if the target node was temporarily unresponsive.

• RS169857: Fixed an issue where dmcproxy could get stuck in restart loops after VM freeze events and repeatedly run unnecessary detailed connection reports.

• RS170790: Fixed an issue where append-only files could become corrupted if the persistent disk ran out of space during write operations, causing partial or missing data at the end of the file.

• RS172012: Fixed an issue with the handling of audit logging connections that could cause high CPU utilization by dmcproxy.

• RS176174: Improved reliability of database upgrades by adjusting shutdown timeouts and restart handling for failed shards.

• RS177036: Fixed an issue where importing RDB files from Azure Blob Storage could fail if the files were stored in subdirectories.

• RS179774: Fixed an issue where installation could fail on systems with firewall enabled due to missing reserved ports in firewalld configuration.

• RS179834: Fixed an issue where client connections could become stuck when using sharded pub/sub commands with the OSS cluster API.

• RS177380: Fixed authorization errors that could occur due to fetching log paths before a user signed in to the Cluster Manager UI.

• RS142855: Enhanced Active-Active database creation API to support mTLS configuration during database creation, allowing client certificate authentication to be configured without requiring changes after creation.

• RS171991: Improved node bootstrapping reliability during cluster patching by increasing retry attempts for connection to the local CCS.

• RS177389: Fixed an issue where database recovery could fail with a retryable error when given an empty recovery plan.

• RS167864: Fixed an issue with the shards API that could cause temporary inconsistencies with shards' reported roles after database upgrades.

• RS180550: Fixed an issue that prevented setting up SSO when the Cluster Manager UI was exposed through an IPv6-based load balancer or gateway.

• RS176474: Fixed an issue where clusters could fail after uploading internal certificates that lacked the "TLS Web Client Authentication" option. The system now validates and rejects certificates without this required option during upload to prevent cluster failures.

• RS182423: Fixed an issue where database availability REST API requests to secondary nodes returned 307 Temporary Redirect status codes instead of the expected availability status.

• RS181962: Fixed an issue where database upgrade operations could become stuck after cluster upgrade.

Version changes

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.
