The new update comes with two major features. The first is GPS support, which makes it possible for Wear apps to track distance, routes, elevation and speed without having a phone nearby.
This is a welcome feature for runners, hikers and bicyclists who don't like exercising or training with armband cases or handling extra baggage during their workouts.
Sadly, this doesn't do any good for existing Wear users whose devices don't come with built-in GPS sensors.
Fortunately, every Wear watch will receive the new update's second main feature: Direct Bluetooth pairing.
Lastly, Google hasn't given any official word on how many Wear-enabled apps are in the Play Store, but it mentioned today that it's somewhere in the "tens of thousands", not too shabby in four months time, and it's large enough to be a pain to search through all of them.
