Google Glass is still very much a pre-release product, but a new update today edges it closer to a shipping device, thanks to some core functionality additions that you’d expect to see in consumer Google hardware. The “XE5” update adds inbound notifications from Google+, so you can see direct shares, comments and mentions, as well as comment and +1 those updates. There are also now Hangout notifications, as well as faster transcription, and a long-press to activate search function available throughout the UI.
