XF 2.1 Upgrades--their effect on template modifications


Well-known member
I've created about eight custom add-ons that probably contain at least 25 template modifications between them. In a couple of cases where the add-on is ill-behaved in its output, the template modifications I have created replace other template modifications that other add-on authors have created. What I do there is deactivate the template modification using the provided switch in the list of modifications.

What happens during an XF version upgrade? Does the on/off status of the template modifications remain the same, or do they default to being reactivated during an upgrade if they are turned off? I am thinking they will remain at the same status, but wanted to verify it so I don't have any unexpected surprises the next time we run an upgrade.
