v1.6.1

v1.6.1 is a feature release:

• KIP-429: Incremental consumer rebalancing - see cooperative_consumer_example.go for an example how to use the new incremental rebalancing consumer.
• KIP-480: Sticky producer partitioner - increase throughput and decrease latency by sticking to a single random partition for some time.
• KIP-447: Scalable transactional producer - a single transaction producer can now be used for multiple input partitions.
• Add support for go.delivery.report.fields by @kevinconaway

Fixes

• For dynamically linked builds (-tags dynamic) there was previously a possible conflict between the bundled librdkafka headers and the system installed ones. This is now fixed. (@KJTsanaktsidis)

confluent-kafka-go is based on and bundles librdkafka v1.6.1, see the librdkafka release notes for a complete list of changes, enhancements, fixes and upgrade considerations.
