The Google Glass team hasn't taken a break since pushing out XE16 - there have been four updates so far, and according to Glass team member Kiley, there's another on the way: XE17.1.
Accompanying the new firmware update, explorers can expect a refreshed MyGlass app. The app will come with a new, more organized design and a new launcher icon.
Explorers should also expect XE17.1 to add the ability to share maps directly from an Android device. This was actually a feature in earlier versions of the Glass firmware, but has been brought back, and should make navigating with Glass a little less awkward. To get navigation started, users need only find the desired destination in Maps, hit the share button, and share to Glass. The headset will handle the rest.
Kiley indicates that both updates should pop up over the next few days.
