- Implement Protocol.__str__ for real consistent hashing + test (#237)
- Add ability to return default value on get but breaking get's API
- Support an arbitrary collection of keys, not just a list
- added TLS support on #211 thanks to @moisesguimaraes!
- moved bmemcached.Client to bmemcached.ReplicantClient but keeps backward compatibility
- added DistributedClient to distribute keys over servers using consistent hashing
