Amazon MSK adds supports for Apache Kafka version 2.5.1

[Amazon Managed Streaming for Apache Kafka](/msk/) (Amazon MSK) now supports Apache Kafka version 2.5.1 for new and existing clusters. Apache Kafka 2.5.1 includes several bug fixes and new features, including encryption in-transit support for Apache ZooKeeper and admin clients ([KIP-515](https://cwiki.apache.org/confluence/display/KAFKA/KIP-515%3A+Enable+ZK+client+to+use+the+new+TLS+supported+authentication)). For a complete list of improvements and bug fixes, see the Apache Kafka release notes for 2.5.0 and 2.5.1. Amazon MSK is a fully managed service for Apache Kafka that makes it easy for you to build and run applications that use Apache Kafka as a data store. Amazon MSK is 100% compatible with Apache Kafka, which enables you to quickly migrate your existing Apache Kafka workloads to Amazon MSK with confidence or build new ones from scratch. With Amazon MSK, you spend more time innovating on applications and less time managing clusters. To learn how to get started, see the [Amazon MSK Developer Guide](https://docs.aws.amazon.com/msk/latest/developerguide/getting-started.html). Support for Apache Kafka version 2.5.1 is offered in all [AWS regions](/about-aws/global-infrastructure/regional-product-services/) where Amazon MSK is available.
