Serenity Caldwell takes you on a tour through Apple’s upcoming Apple Watch OS update. Of note:

Apple’s 2016 software updates are currently available only as closed developer previews. While the betas contain new features, they also contain pre-release bugs that can prevent the normal use of your iPhone, iPad, Apple Watch, Apple TV, or Mac, and are not intended for everyday use on a primary device. That’s why we strongly recommend you stay away, at least until the public iOS and macOS betas in July, if not the general releases this fall.

I depend on my Apple Watch too much to make the update and will follow this advice.

That said, take a read through the article to get a sense of the big changes.
