## RabbitMQ 3.6.3
RabbitMQ `3.6.3` is a maintenance release that includes
bug fixes, packaging and build system enhancements.
As of `3.6.3`, RabbitMQ also comes with several additional plugins in the distribution:
* [rabbitmq_top](http://github.com/rabbitmq/rabbitmq-top), which helps identify (Erlang) processes
that consume most RAM and CPU resources
* [rabbitmq_trust_store](https://github.com/rabbitmq/rabbitmq-trust-store) which manages
trusted client x509/TLS certificates
* [rabbitmq_jms_topic_exchange](https://github.com/rabbitmq/rabbitmq-jms-topic-exchange/) which, together with [RabbitMQ JMS Java client](https://github.com/rabbitmq/rabbitmq-jms-client), provides support for the JMS 1.1 API
atop RabbitMQ.
### Breaking Changes
* Debian package now [supports systemd and also drops support for some older distributions](https://groups.google.com/forum/#!topic/rabbitmq-users/orFuEYExcxk).
* All artifacts in this release are signed with a [new 4096-bit OpenGPG key](https://groups.google.com/forum/#!msg/rabbitmq-users/BO5cmEsdEhc/Jupz1_Q4AwAJ).
### Known Issues on Erlang 19.0
An undocumented runtime metric change in Erlang 19.0 [breaks management plugin](https://github.com/rabbitmq/rabbitmq-management/issues/244).
### Server
#### Bug Fixes
* (Newly elected) queue leader process could terminate immediately after promotion
GitHub issue: [rabbitmq-server#812](https://github.com/rabbitmq/rabbitmq-server/issues/812)
* Priority queue mirror could fail to synchronize after restart
GitHub issues: [rabbitmq-server#687](https://github.com/rabbitmq/rabbitmq-server/issues/687), [rabbitmq-server#802](https://github.com/rabbitmq/rabbitmq-server/issues/802)
* Shutdown timeouts for worker processes are now much more reasonable.
Earlier the timeouts were virtually infinite which could lead to a deadlock during node shutdown.
GitHub issue: [rabbitmq-server#541](https://github.com/rabbitmq/rabbitmq-server/issues/541)
* Purging of a durable queue could result in undelivered publisher confirms.
Contributed by Andreas Ländle.
GitHub issue: [rabbitmq-server#854](https://github.com/rabbitmq/rabbitmq-server/issues/854)
* Old incarnations of queue mirrors are now ensured to be stopped before new ones are started
GitHub issue: [rabbitmq-server#863](https://github.com/rabbitmq/rabbitmq-server/issues/863)

* More efficient file handle management
GitHub issue: [rabbitmq-server#828](https://github.com/rabbitmq/rabbitmq-server/issues/828)
* Test suite ported to Common Test
Plugin developers will be encouraged to port their test suites to Common Test
in the future.
GitHub issue: [rabbitmq-server#725](https://github.com/rabbitmq/rabbitmq-server/issues/725)
* Compilation on [Erlang/OTP 19.0](http://erlang.org/download/otp_src_19.0.readme).
GitHub issue: [rabbitmq-server#860](https://github.com/rabbitmq/rabbitmq-server/issues/860)
