3.6.x Series Support Timeline

Please read this node on RabbitMQ 3.6.x series support timeline.

Core Server

Bug Fixes

• Memory usage monitor uses subprocesses a lot more sparingly. They are started roughly once a second or not started at all, depending on the strategy (e.g. on Windows Erlang VM allocator information is used instead).

  GitHub issues: rabbitmq-server#1343, rabbitmq-common#224

• Very busy queues are now more efficient at prioritizing consumers, avoiding consumer delivery blocking when relatively long running operations (e.g. bulk flushing of transient messages to disk) happen.

  GitHub issues: rabbitmq-server#1388, rabbitmq-server#1407

• queue leader strategies now take additional queue HA arguments into account.

  GitHub issue: rabbitmq-server#1371

• Logging to standard output using RABBITMQ_LOGS=- wasn't possible on Windows.
