The New Stack is a publication covering trends and technologies in cloud-native development, DevOps, and software delivery.

Apache Kafka 4.1 introduces three major developer-focused features: Queues for Kafka (KIP-932) enabling cooperative message consumption with per-message acknowledgment, native JWT-Bearer authentication support eliminating static credentials, and a new Kafka Streams rebalance protocol for better coordination. The release also includes improvements to consumer group protocols, transaction handling, and unified metrics.
