Google released their update for Glass a little more than a week ago and following the trend of other updates, named it XE10. This update is not as large as XE9, but does bring with it some interesting new features.
Firstly, it has the ability to inform you of mass transit features near your location. Things like where to change trains and how far is the next bus stop are now added in Glass. In addition to this, Glass users can now tap links in Google Glass. This has been a big problem for many glass users for a while now, so it seems that Google are indeed working on customer feedback.
There's also the addition of Avatars in messages and comments, which is pretty useful. Further to these updates, coders have also found files related to double blink detection in the Gaze folder. This could mean the use of double blinking as a selection mechanism in future Google Glass updates. Guess we'll just have to wait and see how that one pans out.
