text:
#### Legacy UI deprecation

The legacy UI is deprecated in favor of the new Cluster Manager UI and will be removed in a future release.

#### Redis 6.0 database deprecation

Redis database version 6.0 is deprecated as of Redis Enterprise Software version 7.4.2 and will be removed in a future release.

To prepare for the future removal of Redis 6.0:

- For Redis Enterprise 6.2.* clusters, upgrade Redis 6.0 databases to Redis 6.2. See the [Redis 6.2 release notes](https://raw.githubusercontent.com/redis/redis/6.2/00-RELEASENOTES) for the list of changes.

- For Redis Enterprise 7.2.4 and 7.4.x clusters, upgrade Redis 6.0 databases to Redis 7.2. Before you upgrade your databases, see the list of [Redis 7.2 breaking changes]() and update any applications that connect to your database to handle these changes.

#### End of triggers and functions preview

The [triggers and functions]() (RedisGears) preview has been discontinued.

- Commands such as `TFCALL`, `TFCALLASYNC`, and `TFUNCTION` will be deprecated and will return error messages.

- Any JavaScript functions stored in Redis will be removed.

- JavaScript-based triggers will be blocked.

- Lua functions and scripts will not be affected.

If your database currently uses triggers and functions, you need to:

1. Adjust your applications to accommodate these changes.

1. Delete all triggers and functions libraries from your existing database:

    1. Run `TFUNCTION LIST`.

    1. Copy all library names.

    1. Run `TFUNCTION DELETE` for each library in the list.

    If any triggers and functions libraries remain in the database, the RDB snapshot won't load on a cluster without RedisGears.

1. Migrate your database to a new database without the RedisGears module.

#### RedisGraph end of life

RedisGraph reached end of life on January 31, 2025. See the [RedisGraph end-of-life announcement](https://redis.com/blog/redisgraph-eol/) for more details.

#### Open source Redis security fixes compatibility

As part of Redis's commitment to security, Redis Enterprise Software implements the latest [security fixes](https://github.com/redis/redis/releases) available with [open source Redis](https://github.com/redis/redis). Redis Enterprise has already included the fixes for the relevant CVEs.

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

Redis Enterprise 7.4.6-268 supports open source Redis 7.2, 6.2, and 6.0. Below is the list of open source Redis CVEs fixed by version.

Redis 7.2.x:

- (CVE-2025-32023) An authenticated user can use a specially crafted string to trigger a stack/heap out-of-bounds write on HyperLogLog operations, which can lead to remote code execution.

- (CVE-2025-21605) An unauthenticated client can cause unlimited growth of output buffers until the server runs out of memory or is terminated, which can lead to denial-of-service.

- (CVE-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.

- (CVE-2024-31228) An authenticated user can trigger a denial-of-service by using specially crafted, long string match patterns on supported commands such as `KEYS`, `SCAN`, `PSUBSCRIBE`, `FUNCTION LIST`, `COMMAND LIST`, and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crashes.

- (CVE-2023-41056) In some cases, Redis may incorrectly handle resizing of memory buffers, which can result in incorrect accounting of buffer sizes and lead to heap overflow and potential remote code execution.

- (CVE-2023-41053) Redis does not correctly identify keys accessed by `SORT_RO` and, as a result, may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration. (Redis 7.2.1)

Redis 7.0.x:

- (CVE-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.

#### Redis module feature sets

Redis Enterprise comes packaged with several modules. As of version 7.4.2, Redis Enterprise includes two feature sets, compatible with different Redis database versions.

Bundled Redis modules compatible with Redis database version 7.2:

- [RediSearch 2.8]()

- [RedisJSON 2.6]()

- [RedisTimeSeries 1.10]()

- [RedisBloom 2.6]()

- [RedisGears 2.0 preview](https://github.com/RedisGears/RedisGears/releases/tag/v2.0.20-m21): The RedisGears preview will not be promoted to GA and will be removed in a future release.

Bundled Redis modules compatible with Redis database versions 6.0 and 6.2:

- [RediSearch 2.6]()

- [RedisJSON 2.4]()

- [RedisTimeSeries 1.8]()

- [RedisBloom 2.4]()

- [RedisGraph v2.10](): RedisGraph end-of-life has been announced and will be removed in a future release. See the [RedisGraph end-of-life announcement](https://redis.io/blog/redisgraph-eol/) for more details.

#### End-of-life policy extension

The end-of-life policy for Redis Enterprise Software versions 6.2 and later has been extended to 24 months after the formal release of the subsequent major version. For the updated end-of-life schedule, see the [Redis Enterprise Software product lifecycle]().

#### Supported upgrade paths

Redis Enterprise Software versions 6.2.4 and 6.2.8 do not support direct upgrades beyond version 7.4.x. Versions 6.2.10, 6.2.12, and 6.2.18 are part of the [upgrade path](). To upgrade from 6.2.4 or 6.2.8 to versions later than 7.4.x, an intermediate upgrade is required.

The next major Redis Enterprise Software release will still bundle Redis database version 6.2 and allow database upgrades from Redis database version 6.2 to 7.x.

See the [Redis Enterprise Software product lifecycle]() for more information about release numbers.

#### Default image change for Redis Enterprise Software containers

Starting with the next major version, Redis Enterprise Software containers with the image tag `x.y.z-build` will be based on RHEL instead of Ubuntu.

This change will only affect you if you use containers outside the official [Redis Enterprise for Kubernetes]() product and use Ubuntu-specific commands.

To use Ubuntu-based images after this change, you can specify the operating system suffix in the image tag. For example, use the image tag `7.4.2-216.focal` instead of `7.4.2-216`.

- RS131972: Creating an ACL that contains a line break in the Cluster Manager UI can cause shard migration to fail due to ACL errors.

- RS61676: Full chain certificate update fails if any certificate in the chain does not have a Common Name (CN).

- RS119958: The `debuginfo` script fails with the error `/bin/tar: Argument list too long` if there are too many RocksDB log files. This issue only affects clusters with Auto Tiering.

title: Known limitations

text:
#### New Cluster Manager UI limitations

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

- Remove a node.

    Use the REST API or legacy UI instead. See [Remove a cluster node]() for instructions.

- Purge an Active-Active instance.

    Use [`crdb-cli crdb purge-instance`]() instead.

- Search and export the log.

#### OpenSSL compatibility issue for 7.4.2 modules on Amazon Linux 2

Due to an OpenSSL 1.1 compatibility issue between modules and clusters, Redis Enterprise Software version 7.4.2-54 is not fully supported on Amazon Linux 2 clusters with databases that use the following modules: RedisGears, RediSearch, or RedisTimeSeries.

This issue will be fixed in a future maintenance release.

#### RedisGraph prevents upgrade to RHEL 9

You cannot upgrade from a prior RHEL version to RHEL 9 if the Redis Enterprise cluster contains a RedisGraph module, even if unused by any database. The [RedisGraph module has reached End-of-Life](https://redis.com/blog/redisgraph-eol/) and is completely unavailable in RHEL 9.

title: Redis Software release notes 7.4.6-279 (February 2026)

summary: Internal fixes and improvements.

title: Overview

text: This is a maintenance release for Redis Software version 7.4.6.

title: Highlights

title: New in this release

text:
#### Redis module feature sets

Redis Software comes packaged with several modules. As of version 7.4.2, Redis Software includes two feature sets, compatible with different Redis database versions.

Bundled Redis modules compatible with Redis database version 7.2:

- [RediSearch 2.8]()

- [RedisJSON 2.6]()

- [RedisTimeSeries 1.10]()

- [RedisBloom 2.6]()

- [RedisGears 2.0 preview](https://github.com/RedisGears/RedisGears/releases/tag/v2.0.20-m21): The RedisGears preview will not be promoted to GA and will be removed in a future release.

Bundled Redis modules compatible with Redis database versions 6.0 and 6.2:

- [RediSearch 2.6]()

- [RedisJSON 2.4]()

- [RedisTimeSeries 1.8]()

- [RedisBloom 2.4]()

- [RedisGraph v2.10](): RedisGraph end-of-life has been announced and will be removed in a future release. See the [RedisGraph end-of-life announcement](https://redis.io/blog/redisgraph-eol/) for more details.

title: Version changes

title: Product lifecycle updates

text:
#### End-of-life policy extension

The end-of-life policy for Redis Software versions 6.2 and later has been extended to 24 months after the formal release of the subsequent major version. For the updated end-of-life schedule, see the [Redis Software product lifecycle]().

#### Supported upgrade paths

Redis Software versions 6.2.4 and 6.2.8 do not support direct upgrades beyond version 7.4.x. Versions 6.2.10, 6.2.12, and 6.2.18 are part of the [upgrade path](). To upgrade from 6.2.4 or 6.2.8 to versions later than 7.4.x, an intermediate upgrade is required.

The next major Redis Software release will still bundle Redis database version 6.2 and allow database upgrades from Redis database version 6.2 to 7.x.

See the [Redis Software product lifecycle]() for more information about release numbers.

title: Deprecations

text:
#### Legacy UI deprecation

The legacy UI is deprecated in favor of the new Cluster Manager UI and will be removed in a future release.

#### Redis 6.0 database deprecation

Redis database version 6.0 is deprecated as of Redis Software version 7.4.2 and will be removed in a future release.

To prepare for the future removal of Redis 6.0:

- For Redis Software 6.2.* clusters, upgrade Redis 6.0 databases to Redis 6.2. See the [Redis 6.2 release notes](https://raw.githubusercontent.com/redis/redis/6.2/00-RELEASENOTES) for the list of changes.

- For Redis Software 7.2.4 and 7.4.x clusters, upgrade Redis 6.0 databases to Redis 7.2. Before you upgrade your databases, see the list of [Redis 7.2 breaking changes]() and update any applications that connect to your database to handle these changes.

#### End of triggers and functions preview

The [triggers and functions]() (RedisGears) preview has been discontinued.

- Commands such as `TFCALL`, `TFCALLASYNC`, and `TFUNCTION` will be deprecated and will return error messages.

- Any JavaScript functions stored in Redis will be removed.

- JavaScript-based triggers will be blocked.

- Lua functions and scripts will not be affected.

If your database currently uses triggers and functions, you need to:

1. Adjust your applications to accommodate these changes.

1. Delete all triggers and functions libraries from your existing database:

    1. Run `TFUNCTION LIST`.

    1. Copy all library names.

    1. Run `TFUNCTION DELETE` for each library in the list.

    If any triggers and functions libraries remain in the database, the RDB snapshot won't load on a cluster without RedisGears.

1. Migrate your database to a new database without the RedisGears module.

#### RedisGraph end of life

RedisGraph reached end of life on January 31, 2025. See the [RedisGraph end-of-life announcement](https://redis.com/blog/redisgraph-eol/) for more details.

title: Upcoming changes

text:
#### Default image change for Redis Software containers

Starting with the next major version, Redis Software containers with the image tag `x.y.z-build` will be based on RHEL instead of Ubuntu.

This change will only affect you if you use containers outside the official [Redis Enterprise for Kubernetes]() product and use Ubuntu-specific commands.

To use Ubuntu-based images after this change, you can specify the operating system suffix in the image tag. For example, use the image tag `7.4.2-216.focal` instead of `7.4.2-216`.

title: Known issues

title: Known limitations

text:
#### New Cluster Manager UI limitations

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

- Remove a node.

    Use the REST API or legacy UI instead. See [Remove a cluster node]() for instructions.

- Purge an Active-Active instance.

    Use [`crdb-cli crdb purge-instance`]() instead.

- Search and export the log.

#### OpenSSL compatibility issue for 7.4.2 modules on Amazon Linux 2

Due to an OpenSSL 1.1 compatibility issue between modules and clusters, Redis Software version 7.4.2-54 is not fully supported on Amazon Linux 2 clusters with databases that use the following modules: RedisGears, RediSearch, or RedisTimeSeries.

This issue will be fixed in a future maintenance release.

#### RedisGraph prevents upgrade to RHEL 9

You cannot upgrade from a prior RHEL version to RHEL 9 if the Redis Software cluster contains a RedisGraph module, even if unused by any database. The [RedisGraph module has reached End-of-Life](https://redis.com/blog/redisgraph-eol/) and is completely unavailable in RHEL 9.

title: Security

text:
#### Open source Redis 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 [open source Redis](https://github.com/redis/redis). Redis Software has already included the fixes for the relevant CVEs.

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

Redis Software 7.4.6-279 supports open source Redis 7.2, 6.2, and 6.0. Below is the list of open source Redis CVEs and other security vulnerabilities fixed by version.

title: Version changes

title: Product lifecycle updates

title: Deprecations

text:
#### Legacy UI deprecation

The legacy UI is deprecated in favor of the new Cluster Manager UI and will be removed in a future release.

#### Redis 6.0 database deprecation

Redis database version 6.0 is deprecated as of Redis Enterprise Software version 7.4.2 and will be removed in a future release.

To prepare for the future removal of Redis 6.0:

- For Redis Enterprise 6.2.* clusters, upgrade Redis 6.0 databases to Redis 6.2. See the [Redis 6.2 release notes](https://raw.githubusercontent.com/redis/redis/6.2/00-RELEASENOTES) for the list of changes.

- For Redis Enterprise 7.2.4 and 7.4.x clusters, upgrade Redis 6.0 databases to Redis 7.2. Before you upgrade your databases, see the list of [Redis 7.2 breaking changes]() and update any applications that connect to your database to handle these changes.

#### End of triggers and functions preview

The [triggers and functions]() (RedisGears) preview has been discontinued.

- Commands such as `TFCALL`, `TFCALLASYNC`, and `TFUNCTION` will be deprecated and will return error messages.

- Any JavaScript functions stored in Redis will be removed.

- JavaScript-based triggers will be blocked.

- Lua functions and scripts will not be affected.

If your database currently uses triggers and functions, you need to:

1. Adjust your applications to accommodate these changes.

1. Delete all triggers and functions libraries from your existing database:

    1. Run `TFUNCTION LIST`.

    1. Copy all library names.

    1. Run `TFUNCTION DELETE` for each library in the list.

    If any triggers and functions libraries remain in the database, the RDB snapshot won't load on a cluster without RedisGears.

1. Migrate your database to a new database without the RedisGears module.

#### RedisGraph end of life

Redis has announced the end of life for RedisGraph. Redis will continue to support all RedisGraph customers, including releasing patch versions until January 31, 2025.

See the [RedisGraph end-of-life announcement](https://redis.com/blog/redisgraph-eol/) for more details.

#### Open source Redis security fixes compatibility

As part of Redis's commitment to security, Redis Enterprise Software implements the latest [security fixes](https://github.com/redis/redis/releases) available with [open source Redis](https://github.com/redis/redis). Redis Enterprise has already included the fixes for the relevant CVEs.

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

Redis Enterprise 7.4.6-77 supports open source Redis 7.2, 6.2, and 6.0. Below is the list of open source Redis CVEs fixed by version.

Redis 7.2.x:

- (CVE-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.

- (CVE-2024-31228) An authenticated user can trigger a denial-of-service by using specially crafted, long string match patterns on supported commands such as `KEYS`, `SCAN`, `PSUBSCRIBE`, `FUNCTION LIST`, `COMMAND LIST`, and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crashes.

- (CVE-2023-41056) In some cases, Redis may incorrectly handle resizing of memory buffers, which can result in incorrect accounting of buffer sizes and lead to heap overflow and potential remote code execution.

- (CVE-2023-41053) Redis does not correctly identify keys accessed by `SORT_RO` and, as a result, may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration. (Redis 7.2.1)

Redis 7.0.x:

- (CVE-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.

Redis Software version 7.8.2 introduces the following breaking changes:

- When you upgrade a database, the upgrade process also attempts to upgrade database modules by default.

    - The default value of `latest_with_modules` has changed to `true`.

    - [`rladmin upgrade db`]() will always upgrade the database's modules.

    - When you [upgrade a database]() using the REST API, you can set `"latest_with_modules": false` in the request body to prevent module upgrades.

- Authentication method changes for [`/v1/users/password`]() REST API requests.

    - `PUT`, `POST`, and `DELETE` methods require users to include their usernames and a current password in the authentication header to change their password lists. If the authentication header is not provided, the response status will be `401 Unauthorized`.

    - `/v1/users/password` requests change the password list of the user who provides their credentials in the authorization header when sending the requests.

    - `PUT` and `POST` requests will ignore `username` and `old_password` parameters provided in the request body.

    - `DELETE` requests will ignore the `username` parameter provided in the request body.

- Authentication method changes for [`POST /v1/users/authorize`]() REST API requests.

    - The `POST` method requires users to include their usernames and a current password in the authentication header to generate a JSON Web Token.

    - `POST /v1/users/authorize` generates a token for the user who provides their credentials in the authorization header when sending the requests.

    - `POST` requests will ignore `username` and `password` parameters provided in the request body.

#### Redis database version 7.4 breaking changes {#redis-74-breaking-changes}

When new major versions of Redis Community Edition change existing commands, upgrading your database to a new version can potentially break some functionality. Before you upgrade, read the provided list of breaking changes that affect Redis Software and update any applications that connect to your database to handle these changes.

Confirm your Redis database version (`redis_version`) using the Cluster Manager UI or run the following [`INFO`]() command with [`redis-cli`]():

[code example]

##### Security behavior changes

- [#13108](https://github.com/redis/redis/pull/13108) Lua: LRU eviction for scripts generated with `EVAL`.

##### Other general behavior changes

- [#13133](https://github.com/redis/redis/pull/13133) Lua: allocate VM code with jemalloc instead of libc and count it as used memory.

- [#12171](https://github.com/redis/redis/pull/12171) `ACL LOAD`: do not disconnect all clients.

title: Product lifecycle updates

text:
#### End-of-life policy extension

The end-of-life policy for Redis Software versions 6.2 and later has been extended to 24 months after the formal release of the subsequent major version. For the updated end-of-life schedule, see the [Redis Software product lifecycle]().

#### Supported upgrade paths

Redis Software versions 6.2.4 and 6.2.8 do not support direct upgrades beyond version 7.4.x. Versions 6.2.10, 6.2.12, and 6.2.18 are part of the [upgrade path](). To upgrade from 6.2.4 or 6.2.8 to versions later than 7.4.x, an intermediate upgrade is required.

The next major Redis Software release will still bundle Redis database version 6.2 and allow database upgrades from Redis database version 6.2 to 7.x.

See the [Redis Software product lifecycle]() for more information about release numbers.

#### End of triggers and functions preview

The [triggers and functions]() (RedisGears) preview has been discontinued.

- Commands such as `TFCALL`, `TFCALLASYNC`, and `TFUNCTION` will be deprecated and will return error messages.

- Any JavaScript functions stored in Redis will be removed.

- JavaScript-based triggers will be blocked.

- Lua functions and scripts will not be affected.

If your database currently uses triggers and functions, you need to:

1. Adjust your applications to accommodate these changes.

1. Delete all triggers and functions libraries from your existing database:

    1. Run `TFUNCTION LIST`.

    1. Copy all library names.

    1. Run `TFUNCTION DELETE` for each library in the list.

    If any triggers and functions libraries remain in the database, the RDB snapshot won't load on a cluster without RedisGears.

1. Migrate your database to a new database without the RedisGears module.

title: Reserved ports

title: Deprecations

text:
#### API deprecations

- Deprecated `background_op` field from BDB REST API object. Use [`GET /v1/actions/bdb/<bdb_uid>`]() instead.

- Deprecated the following fields for [upgrade database]() REST API requests:

    - `keep_redis_version`; use `redis_version` instead

    - `current_module`; use `new_module_args` instead

    - `new_module`; use `new_module_args` instead

- Deprecated the following `module_list` fields for [create database]() REST API requests:

    - `module_id`; use `module_name` instead

    - `semantic_version`; use module_args instead

- `min_redis_version` is only relevant to Redis database versions earlier than 7.4 and is replaced with `compatible_redis_version` in [module REST API]() responses.

- Deprecated the [`rladmin upgrade modules`]() command. Use [`rladmin upgrade db`]() instead.

- Deprecated `POST /v1/modules/upgrade/bdb/<uid>` REST API request. Use [`POST /v1/bdbs/<uid>/upgrade`]() to upgrade modules instead.

- Deprecated the `required_version` option for the bootstrap cluster API.

#### V1 Prometheus metrics deprecation

 V1 Prometheus metrics are deprecated but still available. To transition to the new metrics stream engine, either migrate your existing dashboards using [Prometheus v1 metrics and equivalent v2 PromQL]() now, or wait to use new preconfigured dashboards when they become available in a future release.

#### Download center modules deprecation

New Redis modules will not be available for download from the Redis download center.

#### Legacy UI not supported

The legacy UI was deprecated in favor of the new Cluster Manager UI in Redis Software version 7.2.4 and is no longer supported as of Redis Software version 7.8.2.

#### Redis 6.0 databases not supported

Redis database version 6.0 was deprecated in Redis Software version 7.4.2 and is no longer supported as of Redis Software version 7.8.2.

To prepare for the removal of Redis database version 6.0 before you upgrade to Redis Software version 7.8.2:

- For Redis Software 6.2.* clusters:

    1. Set the Redis upgrade policy to `latest`:

        [code example]

    1. [Upgrade Redis 6.0 databases]() to Redis 6.2. See the [Redis 6.2 release notes](https://raw.githubusercontent.com/redis/redis/6.2/00-RELEASENOTES) for the list of changes.

- For Redis Software 7.2.4 and 7.4.2 clusters, upgrade Redis 6.0 databases to Redis 7.2. Before you upgrade your databases, see the list of [Redis 7.2 breaking changes]() and update any applications that connect to your database to handle these changes.

#### Ubuntu 18.04 not supported

Ubuntu 18.04 was deprecated in Redis Software version 7.2.4 and is no longer supported as of Redis Software version 7.8.2.

title: Upcoming changes

text:
#### Default image change for Redis Software containers

Starting with version 7.8, Redis Software containers with the image tag `x.y.z-build` will be based on RHEL instead of Ubuntu.

This change will only affect you if you use containers outside the official [Redis Enterprise for Kubernetes]() product and use Ubuntu-specific commands.

To use Ubuntu-based images after this change, you can specify the operating system suffix in the image tag. For example, use the image tag `7.4.2-216.focal` instead of `7.4.2-216`.

title: Supported platforms

title: Known issues

text:
- RS131972: Creating an ACL that contains a line break in the Cluster Manager UI can cause shard migration to fail due to ACL errors.

- RS151990: For RHEL 8 and RHEL 9 clusters, importing an RDB file can fail with the exception: `Failed to import rdb file: general-error`.

    As a workaround:

    1. On each cluster node, run:

        [code example]

    1. Verify that `libboost_program_options.so.1.75.0` points to a path to confirm the installation succeeded:

        [code example]

    This issue was fixed in [Redis Software version 7.8.6-36]().

title: Known limitations

text:
#### Upload modules before OS upgrade

If the cluster contains any databases that use modules, you must upload module packages for the target OS version to a node in the existing cluster before you upgrade the cluster's operating system.

See [Upgrade a cluster's operating system]() for detailed upgrade instructions.

#### New 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.

#### RedisGraph prevents upgrade to RHEL 9

You cannot upgrade from a prior RHEL version to RHEL 9 if the Redis Software cluster contains a RedisGraph module, even if unused by any database. The [RedisGraph module has reached end-of-life](https://redis.com/blog/redisgraph-eol/) and is completely unavailable in RHEL 9.

#### Query results might include hash keys with lazily expired fields

If one or more fields of a hash key expire after an `FT.SEARCH` or `FT.AGGREGATE` query begins, Redis does not account for these lazily expired fields. As a result, keys with expired fields might still be included in the query results, leading to potentially incorrect or inconsistent results.
