Redpanda SQL is now available on BYOVPC clusters on AWS. Provision the required SQL-specific AWS resources using the Redpanda BYOVPC Terraform module, then supply them as customer-managed resources when enabling the SQL engine via the Cloud Console, Cloud API, or Terraform provider. See xref:sql:get-started/enable-sql-byovpc-aws.adoc[Enable Redpanda SQL on a BYOVPC Cluster on AWS].

=== Decode Iceberg keys, values, and headers independently

On BYOC clusters with Iceberg-enabled topics, the `redpanda.iceberg.mode` topic property now accepts a section-based syntax that lets you independently control how Redpanda translates the record key, value, and headers into the Iceberg table. You can decode keys and header values using a schema or store them as UTF-8 strings, instead of the default raw bytes. See xref:manage:iceberg/specify-iceberg-schema.adoc#configure-key-value-and-header-translation[Configure key, value, and header translation].

=== Resolve Iceberg topic schemas within a Schema Registry context

On BYOC clusters, you can now set the `redpanda.schema.registry.context` topic property on an Iceberg-enabled topic to resolve its schemas within a specific xref:manage:schema-reg/schema-reg-contexts.adoc[Schema Registry context] instead of the default context. See xref:manage:iceberg/specify-iceberg-schema.adoc#resolve-schemas-within-a-context[Resolve schemas within a Schema Registry context].

=== Expanded Kafka client validation

Redpanda now validates additional non-Java Kafka clients at their current versions, aligned with Kafka 4.x: confluent-kafka-go, Sarama, and confluent-kafka-python. See xref:develop:kafka-clients.adoc[Kafka Compatibility].

Document the validated client versions and expose them in the linked compatibility page.

The cloud-rendered page omits these three clients and lists no explicit versions, so this release note’s claim cannot be substantiated.

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In `@modules/get-started/pages/whats-new-cloud.adoc` around lines 19 - 21, Update
the “Expanded Kafka client validation” release-note section to state the
validated versions for confluent-kafka-go, Sarama, and confluent-kafka-python,
and update the linked Kafka Compatibility page to include matching entries for
all three clients. Ensure the release note and compatibility table use the same
explicit version details.
