I've not tested it yet, but it seems all automations can now be set to run automatically without totally making themselves useless by just popping up a prompt to run.
I'll see if my "leaving home" automation runs and edit this later.
Speaking of automations/shortcuts, there's now a 2x2 widget that can house 2 shortcuts (instead of just the one as was the case prior).
Edit: My location-based automations failed to run. They didn't even try. I've never had much luck with automations being triggered by location - it's been crappy on my phone for many iOS versions.
Edit more: I set an automation to trigger by joining and leaving WiFi instead (as that's the same, for me, as triggering on a location) and that worked. It ran automatically, although I did get a notification saying it had run.
