RabbitMQ 3.5.1 发布，此版本是个 bug 修复版本，主要改进如下：
服务器
功能增强
Introduce a new channel log category for channel log messages (rabbitmq/rabbitmq-server#74).
Bug 修复
Ensure consumer_closed events are emitted for the actually closed channels only, not all of them (since 3.3.0, rabbitmq/rabbitmq-server#86). The events were filtered later in the management plugin so the behaviour was correct. However, the broker did way too much work.
Ensure the number of x-death message headers doesn't grow indefinitely (rabbitmq/rabbitmq-server#78). Now, there is a single entry for each {queue, reason} pair.
Adjust the file read buffer cache size to avoid useless reads (since 3.5.0, rabbitmq/rabbitmq-server#69). Before this fix, reading a file backward would cause the buffer to be filled and thrown away quickly, leading to a large I/O bandwidth consumption.
Ensure the priority queue plugin reports its memory consumption properly (since 3.5.0, rabbitmq/rabbitmq-server#67). Before this fix, the queue might not be paged out under memory pressure.
Prevent a crash while synchronising paged out priority queues (since 3.5.0, rabbitmq/rabbitmq-server#65). This was caused by priority queues accessing message properties without checking their existence.
Pass the PID file to rabbitmqctl stop in rabbitmq-server.ocf, exactly like Debian- and Red Hat-flavour init scripts (since 2.6.0, rabbitmq/rabbitmq-server#72).

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。
