Please see the Kafka 2.1.0 release plan for more details: *https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=91554044* <https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=91554044> Here are a few notable highlights: - 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.
