From Macrumors:

Apple today seeded the first betas of upcoming iOS 14.5 and iPadOS 14.5 updates, and while the new software serves as a deadline for when app developers must comply with App Tracking Transparency rules, there are also a handful of other changes worth noting.

The headline feature is the ability to unlock your phone with a watch when you’re wearing a mask. It’s also nice to see Apple getting into the habit of shipping features when they’re ready instead of rushing to get them all out at once.
