This Month in RabbitMQ — May 2019

Couple of key public service announcements this month. First, the deadline for submitting a talk for RabbitMQ Summit 2019 (5 November in London UK) was May 10. We had a great line-up last year at the inaugural event and we’re looking forward to an even better event this fall.

Then, on May 23, we’ll be doing an overview of what’s new in RabbitMQ 3.8 (beta 4 of which has dropped recently). Whether you’re a couple versions behind, or on the latest 3.7.14 release, you’re going to want to learn about the latest features and changes.
