RabbitMQ

Bugfixes to the broker, Erlang client, STOMP plugin, and management plugin.

A bugfix release with corrections to the broker, an Erlang client, and a management plugin as well as the shovel and federation plugins.

Unnecessary CPU utilization no longer occurs in the presence of large numbers of idle HA queues. Rapidly declaring and then deleting HA queues no longer crashes the master. This release fixes a race condition in handling node down signals which could result in HA queues failing to restart when bringing a mirror/slave back online. Channels no longer crash when detecting nodes which have gone offline. rabbitmqctl no longer garbles error messages when rendering non-ASCII characters.

Dead lettering; queues can specify an exchange to which messages should be redirected when they are rejected or expire. Internal flow control to limit memory use and make performance more predictable if the server is overloaded.

This release includes fixes to queue recovery and high availability node recovery; fixes to the STOMP adapter; compatibility with the latest Erlang release R15B; and general performance and bugfixes.
