• Java 11 support
• Support for Zstandard, which achieves compression comparable to gzip with higher compression and especially decompression speeds (KIP-110)
• Avoid expiring committed offsets for active consumer group (KIP-211)
• Provide Intuitive User Timeouts in The Producer (KIP-91)

• Kafka's replication protocol now supports improved fencing of zombies. Previously, under certain rare conditions, if a broker became partitioned from Zookeeper but not the rest of the cluster,
  then the logs of replicated partitions could diverge and cause data loss in the worst case (KIP-320).

• Streams API improvements (KIP-319, KIP-321, KIP-330, KIP-353, KIP-356)
• Admin script and admin client API improvements to simplify admin operation (KIP-231, KIP-308, KIP-322, KIP-324, KIP-338, KIP-340)
• DNS handling improvements (KIP-235, KIP-302)
