Outdated help files

I recently downloaded Comodo Dragon. I couldn’t find a way to reopen a recently closed tab though there was supposed to be a simple way to do that so I searched the help files. The problem is I have version 58 of Dragon and the only help files talk about version 52. The information provided also doesn’t apply to 58, since the menu is different and the functions I want appear to have been removed for some unfathomable reason.

This seems sloppy and unprofessional to me. First, features that are supposed to be there are removed but nothing is said about that. Then when I go looking for help, the only official information I can find is outdated and incorrect. Not a good look, Comodo.
