Wow, that's a ton of fixes! Nice work @DJ!
....and thanks for the bug fixes.
Will, no. When ARC was released, the migratory was automatic and moved settings and renamed folders from ezbuilder to arc. After almost 2 years, it’s just useless code occupying resources.
Ahh ok great! Thanks!
@DJ, thanks for keeping ARC working properly! It looks like lots of work.
Haha, how I know people actually read the release notes. That’s great!!
FOR SURE! This is important stuff! Gotta keep up.
