Social sharing was added in the previous update (v2.5, which Rafe looked at in more detail in December last year). Along with the orientation tweak, the stablility of the application has been improved. From the app listing:
Cinemagraph is a magical blend of photo and movie-like animation, creating pictures that seem almost alive. Helpful on-screen assistance lets you select the animated area of your picture and easily create a cinemagraph. The end result is enchanting. You can share your cinemagraph with friends via social media, email and messaging. All you need is a Nokia account and a data connection. You simply upload your cinemagraph to a Nokia server and share the link. Share over WiFi or your mobile data connection, and be sure to check your network operator’s data charges first.
Here's a quick test of the updated lens, with an old classic, the Newton's Cradle (give it a moment or two to load).
Tip of the hat to NokNok, and you'll get more details online via the Windows Store.
