2.5

2.5 introduces a new implementation of the underlying message queue used by subscribers, dispatchers and the publish code to hold messages. The new implementation allows the publish side to provide some backpressure when the network is not as fast as the application.

This new version may change performance characteristics of publishers but should show better overall performance across req/reply and pub/sub scenarios.

Latency should be un-changed.
