[piyushredpanda]

Features

• Schema Registry: Support granular authorization of endpoints via ACLs by @BenPope in #26758
• Support for JSON (via JSON Schema) translation to Iceberg. by @nvartolomei in #26271
• This adds support for using the AWS Glue Data Catalog as an Iceberg REST catalog. To use Glue as an Iceberg REST catalog, configure the standard Iceberg REST catalog and AWS cloud storage configuration and set iceberg_rest_catalog_authentication_mode to aws_sigv4. Additionally, the Glue Data Catalog requires a base location for table storage, configured by iceberg_rest_catalog_base_location. by @wdberkeley in #26363
• Add support for `max.compaction.lag.ms which sets the maximum time before a message becomes eligible for compaction. This can be used to induce periodic compaction of a topic in some cases. by @wdberkeley in #26172
• Add support for min.compaction.lag.ms. In a compacted topic, this property sets the minimum time for which a message will remain ineligible for compaction. This can be used to reduce the frequency of compactions in some cases. by @wdberkeley in #26172
• Added support for the format=serialized query parameter for protobuf schemas for the following schema registry endpoints: by @IoannisRP in #26124
  • get schema/ids/{id}
  • post subject/{sub}
  • get subject/{subject}/version/{version}
  • get subject/{subject}/version/{version}/schema
• Kafka: Implement KIP-700 DescribeCluster (API 60) v0 by @BenPope in #25919
• Redpanda now supports KIP-554 by @michael-redpanda in

• rpk: Get df output in debug bundle by @JFlath in

• Adds the topic_label_aggregation_limit cluster config that when set will dynamically aggregate the topic label in metrics when topic count exceeds the set value. by @ballard26 in #26385
• Force reconfiguration/recovery of partitions now supports updating any in-progress move, regardless of its state. This makes it much easier to use as an escape hatch to recover partitions in various stuck scenarios that would otherwise be difficult to recover. by @bharathv in #26549

• allow use rpk cluster config get in Redpanda cloud clusters. by @andresaristizabal in #26133
