版本变更

添加了验证，以在更新 LDAP 配置时验证 LDAP 服务器 URI 是否包含主机和端口。
的oss_shardingAPI 字段在早期版本的 Redis Software 中没有影响。然而oss_sharding现在将作为未来计划的一部分生效。在另行通知之前，请将此字段设置为false以避免意外影响。

重大更改

Redis 软件版本 7.8.2 引入了以下重大更改：

升级数据库时，默认情况下，升级过程还会尝试升级数据库模块。
- 默认值latest_with_modules已更改为true.
- rladmin upgrade db将始终升级数据库的模块。
- 使用 REST API 升级数据库时，您可以设置"latest_with_modules": false以防止模块升级。

Redis 数据库版本 7.4 重大更改

当 Redis 社区版的新主要版本更改现有命令时，将数据库升级到新版本可能会破坏某些功能。在升级之前，请阅读提供的会影响 Redis Software 的重大更改列表，并更新连接到数据库的任何应用程序以处理这些更改。

确认您的 Redis 数据库版本（redis_version）或运行以下命令INFOcommand 替换为redis-cli:

$ redis-cli -p <port> INFO
"# Server
redis_version:7.0.8
..."

`Security behavior changes`



#13108 Lua: LRU eviction for scripts generated with EVAL.

Other general behavior changes


#13133 Lua: allocate VM code with jemalloc instead of libc and count it as used memory.


#12171 ACL LOAD: do not disconnect all clients.


Product lifecycle updates
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:


Adjust your applications to accommodate these changes.


Delete all triggers and functions libraries from your existing database:


Run TFUNCTION LIST.


Copy all library names.


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.


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


Deprecations
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.


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, upgrade Redis 6.0 databases to Redis 6.2. See the Redis 6.2 release notes 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.
Upcoming changes
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.
Supported platforms
The following table provides a snapshot of supported platforms as of this Redis Software release. See the supported platforms reference for more details about operating system compatibility.
✅ Supported – The platform is supported for this version of Redis Software and Redis Stack modules.
⚠️ Deprecation warning – The platform is still supported for this version of Redis Software, but support will be removed in a future 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.


The server version of Ubuntu is recommended for production installations. The desktop version is only recommended for development deployments.


See the Redis Enterprise for Kubernetes documentation for details about support per version and Kubernetes distribution.


Docker images of Redis Software are certified for development and testing only.


Supported only if FIPS was enabled during RHEL installation to ensure FIPS compliance.


Known issues

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

Known limitations
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 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.
