Here's what Google said in a blog post:
As you zig zag about your day, you can now pull up your agenda by saying "ok glass, google" followed by something like "my agenda” or "what am I doing in November?" This will help you get there on time, keep track of what’s next, and avoid double-booking.In addition new Glass users -- and remember, the program is expanding -- will find a redesigned Glass setup tutorial in XE11 that Google says will show users how to swipe and connect Glass to its companion smartphone app.
When you’re done running around, Glass now makes it easier to get back to work or home. By popular demand, you can now say “ok glass, get directions to home” or “get directions to work.” It’s almost as magical as three ruby-slippered heel clicks.
There will also be a “Start screencast” shortcut in the notification drawer of your connected Android device making it easier for end users to quickly begin screencasting Glass to their smartphone.
Finally, Google has also removed something in XE100. It's the ability to activate Google Search with a long press of the touchpad. Google has removed this because apparently many users were triggering it accidentally.
In addition to an update to the device's firmware, Google has updated the Glass FAQ, removing one fear of Glass users: That if they sold or otherwise redistributed the smart eyewear it would be disabled. Earlier, Google explicitly told Explorers that their Glass units would be disabled if they did so.
The new FAQ says:
Q. Is it OK for Explorers to try and sell their devices online? Will you disable the devices if they do this?
A: The Explorer program is about taking Glass out in the world and seeing what's possible with the technology. We hope our Explorers are excited to do just that. While it's against our terms of service to sell your device, we don't plan on disabling any Explorer's device.
