Posting photo galleries on your WordPress blog is a fun way to share your experiences with the world, but do plain old thumbnail grids truly express your artistic side? No, they don’t. That’s why we’ve added tiled galleries to Jetpack.

Tiled galleries allow you to create beautiful photo mosaics for your blog posts. Just activate the Tiled Gallery module (and optionally set the tiled layout as the default) to create gorgeous galleries in seconds. Your friends will envy you, and your enemies will fear you.

You might be thinking, “Are tiled galleries the only new feature in Jetpack 2.1? If they are, that’s certainly understandable, because it’s an amazing addition to an already feature-rich plugin.” No, tiled galleries are not the only new feature; we’ve also added a slideshow mode for galleries. Just choose Slideshow from the Type dropdown when creating your gallery, and you’ll instantly have a dynamic photo display. Slideshows and tiled galleries both look amazing on mobile devices, and they both integrate seamlessly with the Carousel module.

In addition to giving you new ways to show off your photographs, we’ve spent a lot of time fixing bugs, too. Photon, Infinite Scroll, Publicize, Sharing, and the Contact Form modules have all been given some TLC, and the Custom CSS editor has been updated. For a complete list of changes, see the changelog.
Update: Jetpack 2.1.1 has been released to fix a bug that was preventing updates from Jetpack 1.9.2 and older.
