What’s New

This topic includes new content added in version {page-component-version}. For a complete list of all product updates, see the Redpanda release notes. See also:

  • redpanda-cloud:get-started:whats-new-cloud.adoc

  • Redpanda Cloud vs Self-Managed feature compatibility

Tombstone removal

Redpanda now supports the Kafka delete.retention.ms topic configuration. You can specify how long Redpanda keeps tombstone records for compacted topics by setting delete.retention.ms at the topic level, or tombstone_retention_ms at the cluster level.

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 Mountable topics for details.

Leader pinning

For a Redpanda cluster deployed across multiple availability zones (AZs), 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.

Declarative user and ACL management in Kubernetes

Redpanda now supports declarative management of users and access control lists (ACLs) using the new User custom resource with the Redpanda Operator. This feature allows you to:

  • Create and manage Redpanda users and their authentication settings.

  • Define and manage ACLs to control access to Redpanda resources.

  • Automatically reconcile changes to users and ACLs using the Redpanda Operator.

To learn more, see the User custom resource documentation.

Licensing updates

This release includes several updates to Redpanda’s licensing system to both improve transparency and make it easier to manage licenses across Redpanda clusters and Redpanda Console.

  • Upgrade restriction for enterprise features: You cannot upgrade your cluster to Redpanda 24.3 or later if any enterprise feature of Redpanda (excluding Console) is in use without a valid license. The upgrade is aborted immediately and cleanly before any broker is upgraded, minimizing disruption.

  • License reminder in rpk: Every rpk command now includes a reminder if the cluster is using licensed features without a valid license.

  • License warnings in Redpanda Console: If you are using Redpanda Console and one or more enterprise features are active in the connected Redpanda cluster without a valid license, a banner specifies which enterprise features are in use without a license.

  • 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.

New commands

The following rpk commands are new in this version:

  • rpk cluster storage cancel mount

  • rpk cluster storage list mount

  • rpk cluster storage list-mountable

  • rpk cluster storage mount

  • rpk cluster storage status mount
