This syntax above works fine on any version. The doc you've proposed here needed differnet syntax for pre-4.4.0 since it is attempting to enable wildcards via log_debug=1 or 1:* In OSP we never try todo that as it is almost always overkill. Instead we tell users to just explicitly list each category that is considered important and don't use the wildcards.
