Can you please give us an updated info on the difference. It's clearly outdated.
I found this in the help file that comes with the newest version:
OS authentication and changing expired passwords features are not available.
I think that this information has not been updated for 4-5 years
Here are some changes that you've done lately for Direct Mode
