Mine's a normal size, but I'll give an answer a go.I figure one of your big brains know this answer: since 17.2.1 came out AFTER 17.3 B1, does that generally mean that what got fixed in the x.x.x update isn’t going to be fixed until B2 OR is it usually fixed in the beta then tweaked for the plebs??
It *probably* means 17.3 doesn't have the security fixes that are in 17.2.1 but as Apple haven't released comprehensive release notes for many years (if ever?), there's no way to know for sure.
