 Change log v.0.15.0
 
 **Deprecation**: no more `broadcast`, `unicast`, `multicast` or `write2everyone`... Plezi fully embraced the Pub/Sub design and the [Iodine Extensions to the Rack Websocket Specification Proposal](https://github.com/boazsegev/iodine/blob/master/SPEC-Websocket-Draft.md).
 
 **Feature**: Super powerful Pub/Sub support comes directly from the server layer (iodine), allowing for process cluster Pub/Sub without the need for any Pub/Sub service. Iodine also brings a native Redis connector to easily scale Pub/Sub to multiple machines using a Redis servers.
