Version 1.41.0 (2023-08-21)

What's Changed

🚨 Breaking Changes

Note: this version of Sarama has had a big overhaul in its adherence to the use of the right Kafka protocol versions for the given Config Version. It has also bumped the default Version set in Config (where one is not supplied) to 2.1.0. This is in preparation for Kafka 4.0 dropping support for protocol versions older than 2.1. If you are using Sarama against Kafka clusters older than v2.1.0, or using it against Azure EventHubs then you will likely have to change your application code to pin to the appropriate Version.
