confluent-kafka-go is based on librdkafka v1.7.0, see the librdkafka release notes for a complete list of changes, enhancements, fixes and upgrade considerations.

Enhancements

• Experimental Windows support (by @neptoess).
• The produced message headers are now available in the delivery report Message.Headers if the Producer's go.delivery.report.fields configuration property is set to include headers, e.g.: "go.delivery.report.fields": "key,value,headers" This comes at a performance cost and are thus disabled by default.

Fixes

• AdminClient.CreateTopics() previously did not accept default value(-1) of ReplicationFactor without specifying an explicit ReplicaAssignment, this is now fixed.
