Apple released a new round of betas today, but if you're looking for a pack of new features like we saw in Monday's iOS 10.2 and tvOS 10.1 updates, you're out of luck. Today's builds include iOS 10.2.1, macOS 10.12.3 Sierra, and tvOS 10.1.1.
The iOS 10.2.1 notes show a few notes and known issues, although they don't say what exactly is fixed in the update. SOS is only supported in India, and if you delete the new TV app, you won't be able to get it back.
tvOS 10.1.1 is the only new beta where the release notes actually say what's new, but sadly, they only say that there are general bug fixes and improvements in the OS. As for macOS 10.12.3, that's likely bug fixes as well, although as usual, the release notes don't give away any clues.
watchOS is notably missing, as Apple actually had to pull its latest 3.1.1 update, due to it breaking certain devices. It's unclear what the firm plans to do about this, whether it will re-release the update or offer a beta first.
