The modal popup is the single thing I can’t stand about sparkle updates. Why oh why can’t they use the regular notification system and respect DND. It always seems so random as well, it’s not when the application starts or quits, just some rando timer polling for updates to surprise me with an interruption I can’t ignore
Modern versions of Sparkle are a less random in when to show the update alert (lots of software, iTerm including, use ancient versions of Sparkle)
DND is not properly/reliably detectable for 3rd parties. Support for Notification Center is not well designed for a framework to control and works as an auxiliary/supplemental (not primary) functionality for 3rd parties, so apps themselves would have to opt into using it along with adding a lightweight UI indicator which may need to be tailored to the app in question.
