Please note, there have been a few dozen merges that failed to update the
changelog here. As such, the log here should not be considered conclusive as
to the changes that are arriving in 2.3.0.

Changes being made now to ensure more accuracy in the changelog will appear
in all future versions going forward. Read the commit history for a better
understanding of changes merged between 2.2.1 and 2.3.0.

All future commits must abide by the new CONTRIBUTING.md document describing
how to label commits so they can be automatically used to automatically
generate an accurate changelog.

*WARNING:* THIS IS THE LAST KAZOO RELEASE THAT SUPPORTS PYTHON 2.6. ALL FUTURE
VERSIONS WILL REQUIRE PYTHON 2.7 AND ABOVE.

Features

- allow having observers and different sized clusters

Bug Handling

- \372: fully resolve multiple records for hosts in the zookeeper
