The Pivotal team is pleased to announce the release of RabbitMQ 3.1.0.
This release introduces enhancements and bug fixes to the server, Java client, Erlang client, and a number of plugins, including the management, federation, old-federation, shovel, Web-STOMP, STOMP, and MQTT plugins, as well as the consistent hash exchange. Some of the key, new capabilities include eager synchronisation of mirror queue slaves, automatic cluster partition healing, and improved statistics (including charts) in the management plugin.
There also is a newly packaged download available—a standalone release tarball for OS X.
From a performance perspective, several areas have improved—garbage collection, consumption, requeuing, memory use, and dead lettering. The Rabbit team also released some preview screenshots of new features such as the image of new charting below. For more screenshots of additional new features, see RabbitMQ’s blog post of the new release in images.
