HAProxy known bugs for version v2.4.23 (maintenance branch 2.4) :  55 

This version (2.4.23) is a release belonging to maintenance branch 2.4 whose latest version is 2.4.24. If your version is not the last one in the maintenance branch, you are missing fixes for known bugs, and by not updating you are needlessly taking the responsibility for the risk of unexpected service outages and exposing your web site to possible security issues.

The HAProxy development team takes a great care of maintaining stable versions so that all users can apply bug fixes without having to take the risk of upgrading to a new branch. In turn users are expected to apply the fixes when the development team estimates that they were worth being backported to stable branches.
