Are there any known incompatibilities between a config file for haproxy version 1.5 and 1.6? Specifically, is there anything that is valid in 1.5 that is no longer valid in 1.6? I'm asking because I am considering a rebase of haproxy 1.6 in Fedora/RHEL but need to avoid such issues. If I recall, I rebased from 1.4 to 1.5 in Fedora many months back and a user ran into a problem in this regard. Any information is greatly appreciated!
