Although the most recent update to the site contains elements of Google's new design vision - Material Design, the biggest changes involve the further convergence of this product and Google+.
"Starting today, photos with locations that have been shared publicly from your Google+ account will appear in Views (g.co/views) in addition to your photo spheres. Some photos may also appear on +Google Maps, making the map more useful and comprehensive for everyone." - +Evan Rapoport
With this in mind, it would be advisable to check your own profile on Views to make sure you're not accidentally sharing photos not intended to have been shared publicly or with location data enabled. Thankfully, Google has made it easy to change the sharing settings of your photos - Just click on a photo, press the menu button (three dots) and click on "Manage location data" to toggle.
