Prior to Revit 2016 we could either take the Application menu > Licensing or the About Revit route to review our licensing information. Here's the first in 2015.
In 2016 they've removed the Application menu path leaving just the About Revit route.
Not a real hardship, just a big confusing if you were expecting to find it under the Application menu like in the past.
Thanks to Dave for the prompt!
