Such requests will now return the status code `406 Not Acceptable`.\n\n- Node status now returns the actual provisional RAM and flash values even when the maximum number of shards on the node (`max_redis_servers`) is reached. Previously, the API returned 0 for `provisional_ram_of_node` and `provisional_flash_of_node` when a node reached its shard limit.

      "text": "- Upgrading to Redis Software version 8.0.10 through 8.0.16-29 can cause LDAP authentication to fail with \"certificate signed by unknown authority\" errors if your cluster currently uses LDAP authentication. This issue was fixed in [Redis Software version 8.0.16-33](https://redis.io/docs/latest/operate/rs/release-notes/rs-8-0-releases/rs-8-0-16-33).\n\n- For Redis Software versions 8.0.2 through 8.0.10, LDAP filters for `user_dn_query` and `dn_group_query` strictly require parentheses to function correctly. Filters that previously worked without parentheses will no longer work after upgrading to these versions. For example, you must include the parentheses in `(sAMAccountName=%u)`. As of version 8.0.16, this breaking change no longer applies, and both `(sAMAccountName=%u)` and `sAMAccountName=%u` are valid filters.\n\n- Redis Software installation script changes:\n\n    - Changed the `--skip-updating-env-path` option to `--update-env-path` when running [`install.sh`](https://redis.io/docs/latest/operate/rs/installing-upgrading/install/install-script).\n\n    - Changed the `skip_updating_env_path` parameter to `update_env_path` in the [installation answers file](https://redis.io/docs/latest/operate/rs/installing-upgrading/install/manage-installation-questions#configure-file-to-answer)."

      "text": "When new major versions of Redis Open Source 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\n#### ACL behavior changes\n\nBefore Redis 8, the existing [ACL](https://redis.io/docs/latest/operate/rs/security/access-control/redis-acl-overview) categories `@read`, `@write`, `@dangerous`, `@admin`, `@slow`, and `@fast` did not include commands for Redis Search and the JSON, time series, and probabilistic data structures.\n\nStarting with Redis 8, Redis includes all Query Engine, JSON, time series, Bloom filter, cuckoo filter, top-k, count-min sketch, and t-digest commands in these existing ACL categories.\n\nAs a result:\n\n- Existing ACL rules such as `+@read +@write` will allow access to more commands than in previous versions of Redis. Here are some examples:\n\n  - A user with `+@read` access will be able to execute `FT.SEARCH`.\n\n  - A user with `+@write` access will be able to execute `JSON.SET`. \n\n- ACL rules such as `+@all -@write`  will allow access to fewer commands than previous versions of Redis.\n\n  - For example, a user with `+@all -@write` will not be able to execute `JSON.SET`.\n\n  - Explicit inclusion of new [command categories](https://redis.io/docs/latest/operate/oss_and_stack/management/security/acl#command-categories) is required to maintain access. The new categories are: `@search`, `@json`, `@timeseries`, `@bloom`, `@cuckoo`, `@topk`, `@cms`, and `@tdigest`.\n\n- ACL rules such as `+@read +JSON.GET` can now be simplified as `+@read` because `JSON.GET` is included in the `@read` category.\n\nNote that the `@all` category did not change, as it always included all the commands.\n\n#### Redis Search changes\n\nThe following changes affect behavior and validation in Redis Search:\n\n- Enforces validation for `LIMIT` arguments (offset must be 0 if limit is 0).\n\n- Enforces parsing rules for `FT.CURSOR READ` and `FT.ALIASADD`.\n\n- Parentheses are now required for exponentiation precedence in `APPLY` expressions.\n\n- Invalid input now returns errors instead of empty results.\n\n- Default values revisited for reducers like `AVG`, `COUNT`, `SUM`, `STDDEV`, `QUANTILE`, and others.\n\n- Updates to scoring (`BM25` is now the default instead of `TF-IDF`).\n\n- Improved handling of expired records, memory constraints, and malformed fields."

      "text": "On RHEL 9, Redis Software versions 8.0.16 through 8.0.20-68 require OpenSSL 3.3 or later. Version 8.0.20-96 and later are built against an earlier OpenSSL version, so the requirement no longer applies. Other supported platforms are unaffected.\n\nThe requirement exists because those versions are built against the OpenSSL 3.3 runtime included in recent RHEL 9 minor releases. Nodes on an earlier RHEL 9 minor release don't meet it. For example, RHEL 9.6 ships OpenSSL 3.2.2.\n\nThe pre-upgrade checks don't detect an incompatible OpenSSL version, so an upgrade can pass validation and then fail partway through. This can leave the management services on the node in a failed state.\n\nBefore you upgrade to a version between 8.0.16 and 8.0.20-68, check the OpenSSL version on each node:\n\n[code example]\n\nIf the version is earlier than 3.3.0, either upgrade the `openssl` and `openssl-libs` packages first, or upgrade to Redis Software version 8.0.20-96 or later instead."

Use [`PUT /v1/cluster/policy`](https://redis.io/docs/latest/operate/rs/references/rest-api/requests/cluster/policy#put-cluster-policy) to change cluster policies after cluster creation instead.\n\n- Deprecated the `module_args` field for [database](https://redis.io/docs/latest/operate/rs/references/rest-api/requests/bdbs) REST API requests. Use the new module configuration objects `search`, `timeseries`, and `probabilistic` instead.\n\n- Deprecated `event_archive_cleanup_task_settings` for `job_scheduler` REST API requests.\n\n#### Redis Search deprecations\n\n- Deprecated commands: `FT.ADD`, `FT.SAFEADD`, `FT.DEL`, `FT.GET`, `FT.MGET`, `FT.SYNADD`, `FT.DROP`, `FT._DROPIFX`, and `FT.CONFIG`.\n\n- Deprecated `FT.SEARCH` options: `GEOFILTER`, `FILTER`, and `NOSTOPWORDS`.\n\n- Deprecated vector search options: `INITIAL_CAP` and `BLOCK_SIZE`.\n\n- Deprecated configuration parameters: `WORKER_THREADS`, `MT_MODE`, `PRIVILEGED_THREADS_NUM`, and `GCSCANSIZE`.\n\n- Deprecated dialects: `DIALECT 1`, `DIALECT 3`, and `DIALECT 4`.\n\n#### Internal monitoring and v1 Prometheus metrics deprecation\n\nThe existing [internal monitoring engine](https://redis.io/docs/latest/operate/rs/monitoring/v1_monitoring) is deprecated. We recommend transitioning to the new [metrics stream engine](https://redis.io/docs/latest/operate/rs/monitoring/metrics_stream_engine) for improved performance, enhanced integration capabilities, and modernized metrics streaming.\n\nV1 Prometheus metrics are deprecated but still available. To transition to the new metrics stream engine, either migrate your existing dashboards using [this guide](https://redis.io/docs/latest/operate/rs/references/metrics/prometheus-metrics-v1-to-v2) or use [new preconfigured dashboards](https://redis.io/docs/latest/integrate/prometheus-with-redis-enterprise#grafana-dashboards-for-redis-software).\n\nAs part of the transition to the metrics stream engine, some internal cluster manager alerts were deprecated in favor of external monitoring solutions. See the [alerts transition plan](https://redis.io/docs/latest/operate/rs/references/alerts/alerts-v1-to-v2) for guidance."

      "role": "content",
      "text": "#### Redis Search query failures during rolling upgrades across the 8.4 version boundary\n\nRedis 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.\n\n#### Trim ACKED not supported for Active-Active 8.4 databases\n\nFor Active-Active databases running Redis database version 8.4, the `ACKED` option is not supported for trimming commands.\n\n#### Rolling upgrade limitation for clusters with custom or deprecated modules\n\nDue 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.\n\n#### Module commands limitation during Active-Active database upgrades to Redis 8.0\n\nWhen 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.\n\n#### Redis 8.0 database cannot be created with flash\n\nYou 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.\n\n#### New Cluster Manager UI limitations\n\nThe following legacy UI features are not yet available in the new Cluster Manager UI:\n\n- Purge an Active-Active instance.\n\n    Use [`crdb-cli crdb purge-instance`](https://redis.io/docs/latest/operate/rs/references/cli-utilities/crdb-cli/crdb/purge-instance) instead.\n\n- Search and export the log.\n\n#### SCAN results can be inconsistent during a rolling upgrade in OSS Cluster API mode\n\nDuring a rolling upgrade with Smart client handoffs (SCH) enabled, when some slot's shards have migrated to a different node but are still reachable from their original node, results of the `SCAN` command might be inconsistent: it might show some of the keys, it might show keys that are not reachable from that node, or it might show no keys. When the slot migration is done, this issue will fix itself."
