Aiven now supports Apache Kafka version 2.5 as a fully managed service, allowing users to launch a managed Kafka service on any of their supported clouds and regions. This release enhances support for Kafka's administrative API, deprecates ZooKeeper, and includes features to support exactly once semantics (EOS). Users can get Aiven for Apache Kafka 2.5 by selecting '2.5' in the drop-down menu from the Kafka service box or using the appropriate switch from the Aiven REST API, command line interface, or Terraform tooling.
