Version 1.7.0 (2015-12-11)

New Features:

• Preliminary support for Kafka 0.9
  (#572). This comes with several
  caveats:
  • Protocol-layer support is mostly in place
    (#577), however Kafka 0.9
    renamed some messages and fields, which we did not in order to preserve API
    compatibility.
  • The producer and consumer work against 0.9, but the offset manager does
    not (#573).
  • TLS support may or may not work
    (#581).

Improvements:

• Don't wait for request timeouts on dead brokers, greatly speeding recovery
  when the TCP connection is left hanging
  (#548).
• Refactored part of the producer. The new version provides a much more elegant
  solution to #449. It is also
  slightly more efficient, and much more precise in calculating batch sizes
  when compression is used
  (#549,
  #550,
  #551).

Bug Fixes:

• Fix race condition in consumer test mock
  (#553).
