This just in from Facebook, new template beginning June 19, 2017:
Facebook is making changes to help organizations like yours find new supporters and stay connected. We've developed a new Page template for nonprofits. It will showcase content from your Page, like photos and events, and make it easier for people to take action with your page.
There's nothing you need to do now. You'll see this change applied on June 19. You can always choose another template and make more changes later. If you're not interested in having this new template applied, you can opt out.
You can apply the new template now and decide if you like the update. If not, you can always back up and go back to the template you prefer.
My suspicion is that it will be worth the change.
