Announcing HAProxy 2.4
HAProxy 2.4 adds exciting features such as support for HTTP/2 WebSockets, authorization and routing of MQTT and FIX (Financial Information Exchange) protocol messages, DNS resolution over TCP, server timeouts that you can change on the fly, dynamic SSL certificate storage for client certificates sent to backend servers, and an improved cache; it adds a built-in OpenTracing integration, new Prometheus metrics, and circuit breaking improvements.
This release was truly a community effort and could not have been made possible without all of the hard work from everyone involved in active discussions on the mailing list and the HAProxy project GitHub. The HAProxy community provides code submissions covering new functionality and bug fixes, documentation improvements, quality assurance testing, continuous integration environments, bug reports, and much more. Everyone has done their part to make this release possible! If you’d like to join this amazing community, y
