We are happy to announce Apache Kafka 4.2.0! Highlights are: Queues for Kafka and the new #KafkaStreams "streams" groups. Thanks to all the 155 contributors and our RM @christo_lolov More details on the web page: kafka.apache.org/blog/2026/01/1…

Uh, changed my mind…

There is a new KIP-1244 proposing to deprecate the Kafka Streams Scala API, and remove it with the next major release. Please join the discussion on the dev mailing list if this concerns you.

Early holiday gift arrived! We are live with our new webpage! Same content. Modern look and modern backend. It’s a huge simplification for maintaining and contributing to the docs. Kudos and thanks to Harish Vishwanath for leading this effort, and David Arthur for shepherding!

Another milestone: KAFKA-20000 was filed today!

We are happy to share that the Apache Kafka 4.1.1 bug-fix release is now available! It contains a critical memory-leak fix for #KafkaStreams and many other fixes. For details see #apache_kafka_411_release_announcement" target="_blank" rel="nofollow noopener">kafka.apache.org/blog#apache_ka… Thanks to 32 contributors and Lianet Magrans as our RM.

We are excited to announce the Apache Kafka 4.0.1 bug-fix release, containing over 40 fixes! Thanks to 53 contributors and your RM @christo_lolov. For more details, checkout the announcement: #apache_kafka_401_release_announcement" target="_blank" rel="nofollow noopener">kafka.apache.org/blog#apache_ka…

🚨Kafka Streams 4.1.0 contains a memory leak regression bug: issues.apache.org/jira/browse/KA… Be careful upgrading, or wait for 4.1.1 bug-fix release. We plan to get it out quickly.

@gwenshap @davidjacot Great to hear! „Doing well“ is rather generic. Can you share more details?

@apachekafka Tell our mutual friend @davidjacot that its doing well :)

Any KIP-848 experience out there? Asking for a friend.
