If the authentication header is not provided, the response status will be `401 Unauthorized`.\n\n - `/v1/users/password` requests change the password list of the user who provides their credentials in the authorization header when sending the requests.\n\n - `PUT` and `POST` requests will ignore `username` and `old_password` parameters provided in the request body.\n\n - `DELETE` requests will ignore the `username` parameter provided in the request body.\n\n- Authentication method changes for [`POST /v1/users/authorize`](https://redis.io/docs/latest/operate/rs/references/rest-api/requests/users/authorize) REST API requests.\n\n - The `POST` method requires users to include their usernames and a current password in the authentication header to generate a JSON Web Token.\n\n - `POST /v1/users/authorize` generates a token for the user who provides their credentials in the authorization header when sending the requests.\n\n - `POST` requests will ignore `username` and `password` parameters provided in the request body.\n\n#### Redis database version 7.4 breaking changes {#redis-74-breaking-changes}\n\nWhen 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.\n\nConfirm your Redis database version (`redis_version`) using the Cluster Manager UI or run the following [`INFO`](https://redis.io/docs/latest/commands/info) command with [`redis-cli`](https://redis.io/docs/latest/operate/rs/references/cli-utilities/redis-cli):\n\n[code example]\n\n##### Security behavior changes\n\n- [#13108](https://github.com/redis/redis/pull/13108) Lua: LRU eviction for scripts generated with `EVAL`. \n\n##### Other general behavior changes\n\n- [#13133](https://github.com/redis/redis/pull/13133) Lua: allocate VM code with jemalloc instead of libc and count it as used memory.\n\n- [#12171](https://github.com/redis/redis/pull/12171) `ACL LOAD`: do not disconnect all clients." }, { "id": "product-lifecycle-updates", "title": "Product lifecycle updates", "role": "content", "text": "#### End-of-life policy extension\n\nThe 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](https://redis.io/docs/latest/operate/rs/installing-upgrading/product-lifecycle).\n\n#### Supported upgrade paths\n\nRedis 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](https://redis.io/docs/latest/operate/rs/installing-upgrading/upgrading/upgrade-cluster#supported-upgrade-paths). To upgrade from 6.2.4 or 6.2.8 to versions later than 7.4.x, an intermediate upgrade is required.\n\nThe 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.\n\nSee the [Redis Software product lifecycle](https://redis.io/docs/latest/operate/rs/installing-upgrading/product-lifecycle) for more information about release numbers.\n\n#### End of triggers and functions preview\n\nThe [triggers and functions](https://redis.io/docs/latest/operate/oss_and_stack/stack-with-enterprise/deprecated-features/triggers-and-functions) (RedisGears) preview has been discontinued.\n\n- Commands such as `TFCALL`, `TFCALLASYNC`, and `TFUNCTION` will be deprecated and will return error messages.\n\n- Any JavaScript functions stored in Redis will be removed. \n\n- JavaScript-based triggers will be blocked.\n\n- Lua functions and scripts will not be affected.\n\nIf your database currently uses triggers and functions, you need to: \n\n1. Adjust your applications to accommodate these changes.\n\n1. Delete all triggers and functions libraries from your existing database:\n\n 1. Run `TFUNCTION LIST`.\n\n 1. Copy all library names.\n\n 1. Run `TFUNCTION DELETE` for each library in the list.\n\n If any triggers and functions libraries remain in the database, the RDB snapshot won't load on a cluster without RedisGears.\n\n1.

To transition to the new metrics stream engine, either migrate your existing dashboards using [Prometheus v1 metrics and equivalent v2 PromQL](https://redis.io/docs/latest/integrate/prometheus-with-redis-enterprise/prometheus-metrics-v1-to-v2) now, or wait to use new preconfigured dashboards when they become available in a future release.\n\n#### Download center modules deprecation\n\nNew Redis modules will not be available for download from the Redis download center.\n\n#### Legacy UI not supported\n\nThe 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.\n\n#### Redis 6.0 databases not supported\n\nRedis 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.\n\nTo prepare for the removal of Redis database version 6.0 before you upgrade to Redis Software version 7.8.2:\n\n- For Redis Software 6.2.* clusters:\n\n 1. Set the Redis upgrade policy to `latest`:\n\n [code example]\n\n 1. [Upgrade Redis 6.0 databases](https://redis.io/docs/latest/operate/rs/installing-upgrading/upgrading/upgrade-database) 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.\n\n- 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](https://redis.io/docs/latest/operate/rs/release-notes/rs-7-2-4-releases/rs-7-2-4-52#redis-72-breaking-changes) and update any applications that connect to your database to handle these changes.\n\n#### Ubuntu 18.04 not supported\n\nUbuntu 18.04 was deprecated in Redis Software version 7.2.4 and is no longer supported as of Redis Software version 7.8.2." }, { "id": "upcoming-changes", "title": "Upcoming changes", "role": "content", "text": "#### Default image change for Redis Software containers\n\nStarting with version 7.8, Redis Software containers with the image tag `x.y.z-build` will be based on RHEL instead of Ubuntu.\n\nThis change will only affect you if you use containers outside the official [Redis Enterprise for Kubernetes](https://redis.io/docs/latest/operate/kubernetes) product and use Ubuntu-specific commands.\n\nTo 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`." }, { "id": "supported-platforms", "title": "Supported platforms", "role": "compatibility", "text": "The following table provides a snapshot of supported platforms as of this Redis Software release.

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.\n\n2. The server version of Ubuntu is recommended for production installations. The desktop version is only recommended for development deployments.\n\n3.

The [RedisGraph module has reached end-of-life](https://redis.com/blog/redisgraph-eol/) and is completely unavailable in RHEL 9.\n\n#### Query results might include hash keys with lazily expired fields\n\nIf 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." } ], "examples": [ { "id": "breaking-changes-ex0", "language": "sh", "code": "$ redis-cli -p INFO\n\"# Server\nredis_version:7.0.8\n...\"", "section_id": "breaking-changes" }, { "id": "deprecations-ex0", "language": "sh", "code": "rladmin tune cluster redis_upgrade_policy latest", "section_id": "deprecations" }, { "id": "known-issues-ex0", "language": "sh", "code": "sudo dnf install boost-program-options", "section_id": "known-issues" }, { "id": "known-issues-ex1", "language": "sh", "code": "ldd /opt/redislabs/bin/rl_rdbloader", "section_id": "known-issues" } ] }
