This lets you give application or tenant teams management access to only their own databases in a shared cluster. - To scope a role, specify the databases it applies to using the new `resources` field when you create or update a [role](https://redis.io/docs/latest/operate/rs/references/rest-api/objects/role). For example, `"resources": [{"type": "db", "uids": ["1", "2"]}]` scopes the role to databases `1` and `2`. - Roles without a `resources` scope continue to apply to all databases, so existing roles are unaffected. - Users assigned a database-scoped role see only their authorized databases in the Cluster Manager UI and REST API responses, including database lists, metrics, alerts, and event logs. Other databases are hidden. ### Data path command auditing Redis Software now supports auditing of data path commands (CRUD operations), in addition to the existing connection auditing. This lets you record which commands run against a database, along with the connection and authentication context, and stream the audit records to an external audit destination for security monitoring and compliance. - Enable auditing per database with the new `audit_settings` configuration, choosing to audit connection events only (`connection`) or both connection events and commands (`connection_and_crud`). - Filter audited commands by username, source IP address, or both to control the volume of audit data. - Monitor the auditing pipeline with new `audit_sink_*` metrics. For more information, see [Audit events](https://redis.io/docs/latest/operate/rs/security/audit-events). ### FIPS 140-3 support Redis supports deployments on RHEL 9 VMs using cryptographic libraries based on FIPS 140-3 validated modules, enabling the use of FIPS-approved cryptographic algorithms in supported environments. - Install Redis Software on a RHEL 9 host that has FIPS mode enabled. See [Supported platforms](#supported-platforms) for the platforms validated for FIPS mode. - In FIPS mode, Redis Software uses only FIPS-approved cryptographic algorithms and cipher suites; non-approved ciphers and algorithms are blocked. - Because FIPS mode fixes the allowed cipher suites, you cannot change the cluster's TLS cipher suites while FIPS mode is enabled. Requests to update them return a `tls_cipher_update_not_allowed` error. For FIPS-mode limitations, see [Increased memory usage in FIPS mode](#increased-memory-usage-in-fips-mode) and [SFTP storage not supported in FIPS mode](#sftp-storage-not-supported-in-fips-mode). ### Enhancements - **Disable Basic authentication for the REST API.** You can now disable Basic and Digest authentication for the cluster management REST API using the new `control_plane_basic_authentication` cluster setting. Basic authentication remains enabled by default; when you disable it, the cluster rejects Basic and Digest authentication on inbound REST API requests. Configure it with [`rladmin tune cluster`](https://redis.io/docs/latest/operate/rs/references/cli-utilities/rladmin/tune) or an [update cluster settings](https://redis.io/docs/latest/operate/rs/references/rest-api/requests/cluster#put-cluster) REST API request. See [Disable basic authentication for the REST API](https://redis.io/docs/latest/operate/rs/security/access-control/disable-basic-authentication). - **Expose database tags in metrics.** You can now expose selected [database tags](https://redis.io/docs/latest/operate/rs/databases/configure/db-tags) as labels in [v2 metrics](https://redis.io/docs/latest/operate/rs/monitoring/metrics_stream_engine/prometheus-metrics-v2) through a new `db_tags` metric, so you can group, filter, and alert on database metrics by your own tags. Enable it in the cluster's metrics configuration using the `expose_db_tags` and `metrics_tag_keys_exposed` settings. - **Faster replica synchronization.** Redis Software now manages gradual (parallel) synchronization through a `gradual_sync_policy` that applies tuned defaults for common scenarios, such as migration, adding a replica, and Active-Active. This speeds up replica bootstrap in multi-node and multi-shard deployments, such as during upgrades and scaling events, while leaving small deployments unaffected. You can select a policy or set custom parameters with [`rladmin tune db`](https://redis.io/docs/latest/operate/rs/references/cli-utilities/rladmin/tune) or the REST API. - **Certificate–cipher suite validation.** When you upload a cluster certificate, Redis Software now validates that the certificate is compatible with the configured cipher suites and rejects incompatible certificates at upload time, so mismatches are caught early instead of surfacing later. For example, uploading an ECDSA certificate while only RSA-authenticated cipher suites are configured now fails at upload. The check applies to the control-plane certificates (such as `api`, `cm`, and `metrics_exporter`) and to the proxy certificate against the data-path cipher suites. If an upload is rejected, update either the certificate or the configured cipher suites so they are compatible. ### Redis database versions and feature sets Redis Software version 8.2.0 includes the following Redis database versions: 8.6.2, 8.4.0, 8.2.1, 8.0.2, 7.4.3, 7.2.7, and 6.2.13. The [default Redis database version](https://redis.io/docs/latest/operate/rs/databases/configure/db-defaults#database-version) is 8.6. Redis Software includes multiple feature sets, compatible with different Redis database versions.

FIPS mode now excludes SHA and CHACHA20 from `control_cipher_suites`. - RS188659: Fixed an issue where a valid IPv6 address could be misidentified as the localhost loopback address. - RS181161: Fixed an issue where access control users in an error state could not be deleted. - RS177787: Reduced the volume of message logs included in support packages. - RS176225: Fixed an issue where a backup exported from a Memcached database could not be imported. - RS148518: Fixed an issue where an SMTP server could not be configured to send email alerts. - RS144017: Fixed an issue where synchronization could fail with a `-BUSYKEY Target key name already exists` error. ## Version changes ### Breaking changes Redis Software version 8.2.0 introduces the following breaking changes: - **Local import from Redis Software system directories is no longer supported.** To improve security, database imports that use the `mount_point` source can no longer read files from Redis Software system directories, including `/opt/redislabs`, `/var/opt/redislabs`, `/etc/opt/redislabs`, and any of their subdirectories. - Import operations that reference files in these directories now fail. - Store import files in a non-system location accessible to Redis Software before you start the import. - **`smtp_password` is now a write-only field in the Cluster API.** To improve security, the API no longer returns the SMTP password in responses to `GET /v1/cluster`, and the Cluster Manager UI no longer reads or displays the existing password. - Applications or scripts that previously expected `smtp_password` to be returned by the Cluster API no longer receive this field. - When you update SMTP settings, the existing password cannot be retrieved. To change the SMTP password, provide a new password as part of the update request. - **Custom module upload is disabled by default.** To improve security, custom (user-defined) module uploads are now disabled by default. A new cluster setting, `allow_modules_upload`, controls access to the custom module upload APIs. When this setting is disabled (the default), requests to `POST /v2/modules/user-defined` and `POST /v2/local/modules/user-defined/artifacts` return `403 modules_upload_disabled`, regardless of user role. - To enable custom module uploads, set `allow_modules_upload` to `true` with a `PUT /v1/cluster` request. - Applications or automation that call the custom module upload APIs directly receive a `403 modules_upload_disabled` response until the setting is enabled. - Existing functionality for listing, deleting, and loading modules is unchanged. ### OpenSSL version Redis Software version 8.0.16 and later requires OpenSSL 3.3 or later. ### Reserved ports Make sure the following ports are open before upgrading Redis Software. The following port was added as a reserved port in Redis Software version 8.0.18; however, it is optional instead of reserved in Redis Software version 8.0.20-44: | Port | Process name | Usage | |------|--------------|-------| | 3357 | reconciliation_tree_grpc | Internal communication | Ports reserved as of Redis Software version 7.22.0: | Port | Process name | Usage | |------|--------------|-------| | 3346 | cluster_api_internal | Cluster API internal port | | 3351 | cluster_watchdog_grpc_api | Cluster watchdog now supports gRPC | | 3352 | grpc_service_mesh | gRPC communication between nodes | | 3353 | local_grpc_service_mesh | Local gRPC services | | 3354 | grpc_gossip_envoy | gRPC gossip protocol communication between nodes | | 3355 | authentication_service | Authentication service internal port | Ports reserved as of Redis Software version 7.8.2: | Port | Process name | Usage | |------|--------------|-------| | 3347 | cert_exporter | Reports cluster certificate metrics | | 3348 | process_exporter | Reports process metrics for DMC and Redis processes | | 3349 | cluster_wd_exporter | Reports cluster watchdog metrics | | 3350 | db_controller | Internode communication | | 9091 | node_exporter | Reports host node metrics related to CPU, memory, disk, and more | | 9125 | statsd_exporter | Reports push metrics related to the DMC and syncer, and some cluster and node metrics | See [Ports and port ranges used by Redis Software](https://redis.io/docs/latest/operate/rs/networking/port-configurations#ports-and-port-ranges-used-by-redis-enterprise-software) for a complete list. ### Deprecations - The `db_conns_auditing` cluster policy and database configuration field is deprecated. Use the `audit_settings.audit_mode` field instead. Setting `db_conns_auditing` to `true` is equivalent to setting `audit_mode` to `connection`. See [Audit events](https://redis.io/docs/latest/operate/rs/security/audit-events) for the current auditing configuration. - The `gradual_src_mode`, `gradual_sync_mode`, and `gradual_sync_max_shards_per_source` parameters are deprecated. Use `gradual_sync_policy` instead. You can set it with [`rladmin tune db`](https://redis.io/docs/latest/operate/rs/references/cli-utilities/rladmin/tune) or the REST API. - The `old_password` field in `POST /v1/users/password` and `PUT /v1/users/password` requests is deprecated and ignored. It was optional and had no effect when adding or resetting a password, so you can remove it from these requests. `old_password` is still required for `DELETE /v1/users/password`, which uses it to identify the password to delete. - The following REST API fields, deprecated since Redis Software version 6.4.2, are removed in this release: - `use_ipv6` (cluster object) — use `use_external_ipv6` instead. - `redis_cleanup_job_settings` (job scheduler object) — use `persistence_cleanup_scan_interval` instead. ### Supported platforms The following table provides a snapshot of supported platforms as of this Redis Software release. See the [supported platforms reference](https://redis.io/docs/latest/operate/rs/references/supported-platforms) for more details about operating system compatibility. **Amazon Linux 2 is no longer supported.** Starting with Redis Software version 8.0.22, Redis Software no longer builds or publishes Amazon Linux 2 (`amzn2`) packages. Use Amazon Linux 2023 instead. ✅ Supported – The platform is supported for this version of Redis Software and Redis Stack modules. :warning: Deprecation warning – The platform is still supported for this version of Redis Software, but support will be removed in a future release. | Redis Software

Each Go-based control-plane service uses roughly 34 MB more when running in FIPS mode, which adds up to approximately 210 MB of additional memory per node. Account for this overhead when sizing FIPS-enabled deployments. This limitation affects FIPS-enabled builds only. #### SFTP storage not supported in FIPS mode FIPS-enabled builds do not support SFTP as a storage location for backups, imports, or exports, because the SFTP library is not FIPS-compliant. In FIPS mode, use a different storage location. This limitation affects FIPS-enabled builds only. #### Redis Search query failures during rolling upgrades across the 8.4 version boundary Redis Search queries can fail during a rolling upgrade when a cluster contains shards running Redis versions earlier than 8.4 and shards running Redis version 8.4 or later, due to an internal protocol change introduced in version 8.4. This issue affects only clusters where `parallel_shards_upgrade` has been changed from its default value of `0`. If both conditions apply, expect Redis Search downtime until all nodes are upgraded. #### 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`](https://redis.io/docs/latest/operate/rs/references/cli-utilities/crdb-cli/crdb/purge-instance) instead. ## 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.
