Version 1.5.0 (2015-08-17)

New Features:

• TLS-encrypted network connections are now supported. This feature is subject
  to change when Kafka releases built-in TLS support, but for now this is
  enough to work with TLS-terminating proxies
  (#154).

Improvements:

• The consumer will not block if a single partition is not drained by the user;
  all other partitions will continue to consume normally
  (#485).
• Formatting of error strings has been much improved
  (#495).
• Internal refactoring of the producer for code cleanliness and to enable
  future work (#300).

Bug Fixes:

• Fix a potential deadlock in the consumer on shutdown
  (#475).
