-== Tombstone removal 
+== Leader pinning
 
-Redpanda now supports the Kafka `delete.retention.ms` topic configuration. You can specify how long Redpanda keeps xref:manage:cluster-maintenance/compaction-settings.adoc#tombstone-record-removal[tombstone records] for compacted topics by setting `delete.retention.ms` at the topic level, or `tombstone_retention_ms` at the cluster level.
+For a Redpanda cluster deployed across multiple availability zones (AZs), xref:develop:produce-data/leader-pinning.adoc[leader pinning] ensures that a topic's partition leaders are geographically closer to clients. Leader pinning can lower networking costs and help guarantee lower latency by routing produce and consume requests to brokers located in certain AZs.
 
 == Mountable topics
 
 For topics with Tiered Storage enabled, you can unmount a topic to safely detach it from a cluster and keep the topic data in the cluster's object storage bucket or container. You can mount the detached topic to either the same origin cluster, or a different one. This allows you to hibernate a topic and free up system resources taken up by the topic, or migrate a topic to a different cluster. See xref:manage:mountable-topics.adoc[Mountable topics] for details.

+xref:manage:cluster-maintenance/cluster-balancing.adoc#intra-broker-partition-balancing[Intra-broker partition balancing] has moved out of beta and is supported for production clusters. This dynamically balances partitions across cores within a Redpanda broker. You also can decrease the number of CPUs assigned to a broker. Existing partition replicas are reassigned to the remaining CPU cores when the broker restarts with fewer available cores.

+== Backfill partitions
+
+When running xref:manage:cluster-maintenance/nodewise-partition-recovery.adoc[node-wise partition recovery], it's possible that there may be more recent data (a higher offset) available in Tiered Storage. Redpanda attempts to recover partition data from object storage, recovering the latest offset available for a partition in either storage tier (local or object storage). This allows for the maximum amount of data to be recovered in all cases, even for topics with a replication factor of 1, where no replicas remain in local storage.

+== Configure access to object storage with a KMS key

 == Licensing updates

 - *Unified license management in Redpanda Console*: You can now upload and apply a single license key for both Redpanda Console and the connected Redpanda cluster through the Redpanda Console UI. Any existing license key is overridden by the new one.
 
+- *30 day trial Enterprise license*: Starting with version 24.3, new Redpanda clusters automatically receive a trial license that's valid for 30 days, allowing unrestricted use of Enterprise features. This evaluation period begins when the cluster is created for the first time. After this period expires, inactive Enterprise features are disabled, and active features enter a restricted state.
