RabbitMQ 3.6.12 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。

主要更新内容：

核心服务器 Bug 修复：

Process responsible for running the autoheal partition handling strategy
could run into a deadlock with its peers, preventing autoheal from completing.

GitHub issue: rabbitmq-server#1346

Garbage collection of mirrored queue metrics on nodes that did not
host a master or mirror for a queue affected delivery and acknowledgement rates.
This could result in rates being 0 or negative when they should not be.

GitHub issue: rabbitmq-server#1340

Stats emission could prevent queue mirrors from performing garbage collection
and consume memory even when they were empty.

GitHub issue: rabbitmq-common#220 (continuation to rabbitmq-common#196)

RABBITMQ_SCHEDULER_BIND_TYPE and RABBITMQ_DISTRIBUTION_BUFFER_SIZE now can be set via rabbitmq-env.conf.
