Proudly part of Pivotal14 May 2013

RabbitMQ v3.1.0 is significant because it introduces an important set of new features, making Rabbit easier to use and manage.
- Eager synchronisation of mirror queue slaves
- Automatic cluster partition healing
- Improved statistics
V3.1.0 has significance for another reason: it is the first release made under the banner of our new sponsor company, Pivotal. Pivotal launched earlier this year as a joint venture between VMware, EMC and with a strategic partnership with General Electric Global Software. Billed as "A New Platform for a New Era", the Pivotal platform will unite data, application, and cloud fabrics. The Rabbit team members are excited to be part of this bold new initiative driving open source innovation and collaboration.

RabbitMQ will continue to be available under the open source Mozilla Public License or commercial terms. Commercial support, consulting and both self-paced and instructor-led training courses are still available worldwide. The rabbitmq-discuss mailing list will continue to be the primary channel of communication about open-source RabbitMQ. The release cycle is not expected to change as a result of the change of ownership.

We invite all customers to continue with us on the journey to become the most reliable, scalable and portable messaging system.

RabbitMQ is the market leading implementation of AMQP, the interoperable open business messaging protocol, and is distributed on most major development platforms. Already businesses are using RabbitMQ to scale up business-critical application functionality on multiple leading public and private cloud infrastructures. Our support for the VMware vCloud Initiative is a natural extension. RabbitMQ has an open source license making it ideal for elastic deployments, and for integration in platforms such as Spring and Ruby on Rails.
