This Month in RabbitMQ — June 2019

· 4 min read

Welcome back for another edition of This Month in RabbitMQ! Keep sharing your war stories and lessons learned out there, and tweet them with #rabbitMQ to get them on our radar for inclusion in these write-ups.

As we march towards RabbitMQ 3.8 going GA, be sure to catch the replay of the webinar we did last month on what’s new in RabbitMQ 3.8.

Jack Vanlightly also did some coverage on the Single Active Consumer feature in 3.8, adding to his earlier coverage on Quorum Queues.

Project updates

  • RabbitMQ 3.7.15 was released, includes initial support for Erlang 22
  • Erlang 22 is now GA with a new inter-node communication implementation and initial TLSv1.3 server support
  • Erlang 22.0.2 and were released, addressing ERL-934 and ERL-938, an issue that affected RabbitMQ environments that used TLS and had a high data ingestion volume.
  • RabbitMQ Docker image has transitioned to use Erlang 22
  • PerfTest 2.8.0 has been released with lots of goodies: new options to vary message size and publishing rate, optional polling consumers (instead of asynchronous consumers by default), optionally nack messages instead of acking them, and dependency upgrades
  • Java client 5.7.1 (for Java 8+) and 4.11.1 (for Java 6 & 7) have been released with a bug fix
