You can also try a git log on doc/management.txt and doc/configuration.txt it will show the changes. > - Do you suggest me a good way to identify the proxy version so I can > use a distinct parser for the show proc output?

For the `show proc` output, I specifically added a "show version" command in 2.5, which was backported in 2.4.10, 2.3.17, 2.2.20, in the master of the soon to be released 2.0.27. The change in `show proc` was made to remove the relative PID because HAProxy is not multi-process anymore. But if you parse the output by splitting the spaces and keeping the right field with the header you shouldn't have a parsing problem. -- William Lallemand
