RabbitMQ 3.6.3 RC2 发布了，RabbitMQ 是由 LShift 提供的一个 Advanced Message Queuing Protocol (AMQP) 的开源实现，由以高性能、健壮以及可伸缩性出名的 Erlang 写成，因此也是继承了这些优点。

RabbitMQ 3.6.3 RC2是RabbitMQ 3.6.3的一个候选发布版，其中包括bug修复，包装和构建系统的增强功能，以及2个新的插件，开源的RabbitMQ分布。

它包括两个新的插件：

• rabbitmq_trust_store which manages
  trusted client x509/TLS certificates

• rabbitmq_jms_topic_exchange which, together with RabbitMQ JMS Java client, provides support for the JMS 1.1 API
  atop RabbitMQ.

此外，rabbitmq_top现已分布在RabbitMQ的。
