wordpressVersion 4.7.1

Yes, it is. I just learned about this plugin a few minutes ago, installed it on my 4.7.1 blog, activated it, did the Settings/Permalinks save thing, and went to one of my recent post pages. I added “amp/” to the end of that page’s URL in my web browser’s location field when the page came up, and immediately I got a very simplified AMP version of the original page, but with the primary content on it.
