| 32 | +### Deprecations |
| 33 | + |
| 34 | +#### API deprecations |
| 35 | + |
| 36 | +- TBA |
| 37 | + |
| 38 | +#### Internal monitoring and v1 Prometheus metrics deprecation |
| 39 | + |
| 40 | +The existing [internal monitoring engine]({{<relref "/operate/rs/monitoring/v1_monitoring">}}) is deprecated. We recommend transitioning to the new [metrics stream engine]({{<relref "/operate/rs/monitoring/metrics_stream_engine">}}) for improved performance, enhanced integration capabilities, and modernized metrics streaming. |
| 41 | + |
| 42 | +V1 Prometheus metrics are deprecated but still available. To transition to the new metrics stream engine, either migrate your existing dashboards using [this guide]({{<relref "/operate/rs/references/metrics/prometheus-metrics-v1-to-v2">}}) now, or wait to use new preconfigured dashboards when they become available in a future release. |
| 43 | + |
| 44 | +### Supported platforms |
| 45 | + |
| 46 | +The following table provides a snapshot of supported platforms as of this Redis Enterprise Software release. See the [supported platforms reference]({{< relref "/operate/rs/references/supported-platforms" >}}) for more details about operating system compatibility. |
| 47 | + |

| 79 | + |
| 80 | +## Known issues |
| 81 | + |
| 82 | +- RS131972: Creating an ACL that contains a line break in the Cluster Manager UI can cause shard migration to fail due to ACL errors. |
| 83 | + |
| 84 | +- RS155734: Endpoint availability metrics do not work as expected due to a calculation error. |
| 85 | + |
| 86 | +- RS153589: The metrics stream engine preview reports incorrect latency metrics. |
| 87 | + |
| 88 | +## Known limitations |
| 89 | + |
| 90 | +#### Upload modules before OS upgrade |
| 91 | + |
| 92 | +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. |
| 93 | + |
| 94 | +See [Upgrade a cluster's operating system]({{<relref "/operate/rs/installing-upgrading/upgrading/upgrade-os">}}) for detailed upgrade instructions. |
| 95 | + |
| 96 | +#### New Cluster Manager UI limitations |
| 97 | + |
| 98 | +The following legacy UI features are not yet available in the new Cluster Manager UI: |
| 99 | + |
| 100 | +- Purge an Active-Active instance. |
| 101 | + |
| 102 | + Use [`crdb-cli crdb purge-instance`]({{< relref "/operate/rs/references/cli-utilities/crdb-cli/crdb/purge-instance" >}}) instead. |
| 103 | + |
| 104 | +- Search and export the log. |
| 105 | + |
| 106 | +#### RedisGraph prevents upgrade to RHEL 9 |
| 107 | + |
| 108 | +You cannot upgrade from a prior RHEL version to RHEL 9 if the Redis Enterprise 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. |
| 109 | + |
| 110 | +#### Query results might include hash keys with lazily expired fields |
| 111 | + |
| 112 | +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. |
| 113 | + |
| 114 | +#### Active defragmentation does not stop mid-key for JSON |
| 115 | + |
| 116 | +Active defragmentation does not stop mid-key for JSON data. Large keys are defragmented in full, which might cause latency spikes. |
