  • Idempotent producer supports a maximum of 5 in-flight requests per connection instead of 1
  • Improved metrics (KIP-164, KIP-168, KIP-187, KIP-188, KIP-196) and logging
  • Improve diagnostics for SASL and SSL authentication failures (KIP-152
  • Drop support of Java 7 (KIP-118)
  • JBOD support for disk failures (KIP-112)
  • Kafka Streams API improvements (KIP-120 / 130 / 138 / 150 / 160 / 161), and drop compatibility "Evolving" annotations
