v2.7.0

Release 2.7.0

What's changed

[New] Support for Exactly-once processing guarantees using Kafka transactions.

With exactly-once processing guarantees enabled, each Kafka message is processed only one time and without duplicated outputs.

It is especially helpful when consistency of data in the output topics is crucial, and the downstream consumers don't handle duplicated data gracefully.

To learn more about the exactly-once processing and configuration, see the "Processing Guarantees" section here.
