Working on getting them restored, MW 1.26 changed up a few things on how CSS/JS works, so I'll have to make sure they work fine on a MW 1.26 wiki running the same stuff we do (already in progress), and once I confirm that, I'll port it over here and give you an update.
Topic on User talk:DocColress
Alright, thanks! ^^
The Talk/History Gadgets are fully functional and restored. Turn them on if they aren't already. May take a day or two for all changes to apply.
