Release Dates

  • KIP Freeze: May 22, 2018 (a KIP must be accepted by this date in order to be considered for this release)
  • Feature Freeze: May 29, 2018 (major features merged & working on stabilization, minor features have PR, release branch cut; anything not in this state will be automatically moved to the next release in JIRA)
  • Code Freeze: June 12, 2018 (first RC created now)
  • Release: June 26, 2018 (Tentatively)


These dates are goals and subject to change, but we expect to stay on the Time Based Release Plan unless unexpected critical issues come up. While the target release date is fixed at ~2w after code freeze, RCs will roll out as needed until the release vote passes.

The release manager is Rajini Sivaram.

Release Features

This is a list of key features/improvements/bugfixes that we can include with release notes (WIP):

  • Prefixed wildcard ACLs (KIP-290), Fine grained ACLs for CreateTopics (KIP-277)
  • SASL/OAUTHBEARER implementation (KIP-255)
  • Improved quota communication and customization of quotas (KIP-219, KIP-257)
  • Efficient memory usage for down conversion (KIP-283)
  • Fix log divergence between leader and follower during fast leader failover (KIP-279)
  • Drop support for Java 7 and remove deprecated code (e.g old scala clients)
  • Connect REST extension plugin, support for externalizing secrets and improved error handling (KIP-285, KIP-297, KIP-298 etc.)
  • Scala API for Kafka Streams and other Streams API improvements (KIP-270, KIP-150, KIP-245, KIP-251 etc.)

How to Contribute

Before code freeze:

  • Participate in votes and discussions to land or postpone the open KIPs
  • Review patches. We anticipate that this release will be bottlenecked mostly on reviews. The more reviewers, the more content we can fit in.
  • Write unit/integration/system tests. We want to preserve the tradition of high-quality releases in Apache Kafka. 

After code freeze:

  • Write more unit/integration/system testsWe want to preserve the tradition of high-quality releases in Apache Kafka.
  • Improve documentation
  • Test the release candidates
  • Open blocker JIRAs on critical issues found. Open non-blocker JIRAs on any other issues found.
  • Fix critical bugs
  • Review bug fixes
  • Vote on RCs. Even though only PMC votes are binding, community votes are super important as we evaluate the readiness of the release
