The past nine releases of Jetpack have started to reveal our vision for next-generation features that will boost WordPress’ incredible success by making it more social, more connected, more mobile, and more customizable.

Over three million downloads later, we’re excited to report that the community has embraced this seemingly impossible vision for combining the best of hosted and non-hosted WordPress. This tenth release brings some of the most-asked-for features into the hands of millions of Jetpackers.

Publicize to Twitter, Facebook, LinkedIn, Tumblr…

You no longer have to jump through hoops and developer portals to connect your blog to your friends on your favorite social networks. Through Jetpack and your WordPress.com account, you can connect to each network with just a few clicks and broadcast to your audiences and followers across several networks, making WordPress your true digital hub. Activate Publicize from the main Jetpack page in your dashboard, then go to Settings → Sharing to add social sharing connections.

Post by Email

If you live in Gmail, Outlook, your BlackBerry, or just find it easiest to email on the go, you’ll love the new Post by Email feature. Email anything to your secret address — a photo, a video, a bunch of photos, an audio file, ten pages of single-spaced text — and we’ll figure out how to make it beautiful and put it on your blog literally within seconds after you send it. Combined with Publicize and the previously-released Subscriptions module, that post will go out to all your friends including ones that subscribe via email, completing the loop of email / blog nirvana. To set up your special address go to Users → Your Profile in your dashboard and click the “Enable Post By Email” button.

Photon Your Images

Have you ever switched themes to find that full-width images break out of the layout and no longer fit your theme? Are you frustrated that images on your blog take too long to load? Jetpack Photon fixes all of that by making the advanced image acceleration and image editing service from WordPress.com available to the broader WordPress community, essentially making every image a fully dynamic object that themes and plugins can transform to their heart’s content without killing your server. In fact, if you enable Photon, you will see your CPU and bandwidth usage plummet as images are served through the global WordPress.com cloud, meaning less load on your host and faster images for your users.

Infinite Scroll

Infinite Scroll brings the future of reading on the web to your website. Speed and performance are key, and Infinite Scroll loads new content quickly without a full-page refresh. Instead of the old way of navigating down a page — by scrolling and then clicking a link to get to the next page and waiting for the page to refresh — infinite scrolling pulls the next set of posts into view automatically when the reader approaches the bottom of the page. Your theme needs support for this to work. There are already several themes in the directory with Jetpack Infinite Scroll support and theme authors will find documentation for adding it to any theme on jetpack.me.

Onwards…

Jetpack 2.0 isn’t just about shiny new things, we’ve also fixed dozens of bugs and under-the-hood things to keep Jetpack one of the smoothest running, most secure, and most stable plugins out there.

I want to personally thank all of the members of the Jetpack community who have shared countless hours of testing, feedback, and criticism. Your thoughts and passion have made the plugin immeasurably better than it would have been otherwise, and rest assured we’re still listening closely to your feedback around better stats, module activation and deactivation, developer mode, translation, and documentation.
