Hi Ryan, My answer won't be exhaustive, sorry about that. Hopefully, other people may help. I think the configuration parser is less permissive. IE, 2 frontends or 2 backends can't have the same name. The configuration where the listening IP:port address is set on the 'frontend' line is not allowed anymore. More ALERT may also be triggered when the configuration parser doesn't understand a keyword while those keywords used to be silently ignored. (check alertif_too_many_args_idx() ). So by definition, many configuration may be broken. Baptiste
