With the WordPress 4.4 Release Candidate now available, we wanted to release our fully-compatible version of Jetpack a little early. So here it is, along with some minor bug fixes and accessibility improvements.
Photon + Responsive Images
There are some cool things coming in WordPress 4.4, such as responsive images. To take full advantage of this, we made sure that Photon serves responsive images as well.
Twenty Sixteen
If you’ve had the pleasure of testing out Twenty Sixteen, we’ve included some compatibility styling to make sure Jetpack features such as Related Posts, Share Buttons, Likes, and Infinite Scroll all look great.
Accessibility Enhancements
WordPress made some adjustments to the heading levels in 4.4 to improve accessibility. We scrubbed Jetpack to make sure our heading levels are semantic and accessible to screen readers as well.
More Streamlined
We went through and optimized the images that we display within the Jetpack Admin, which dropped our image directory from 1.8 MB to 856 KB. Every little bit counts!
Bug Fixes
Fixed some minor bugs with Carousel, Markdown, Single Sign On, and Subscriptions.
Contributors for this release include Adam Heckler, Alex Kirk, Brandon Kraft, Chris Wiegman, Derek Smart, Eduardo Reveles, Enej Bajgoric, Ian Dunn, Igor Zinovyev, Jake Jackson, Jeff Golenski, Jeremy Herve, Joey Kudish, Konstantin Obenland, Michael Cain. Miguel Lezama, Rocco Tripaldi, Sam Hotchkiss, Scott Grant, and Takashi Irie.
Jetpack 
Using the Avada theme. I was going nuts trying to figure out why my images would not update when I edited them. Theme Fusion advised me that it was because of the cache in Photon? Is this right?

Correct – Photon images are currently cached “forever”. If you want to refresh an image you will need to change the name of the image. Adding random query arguments, commonly known as cachebusters, will not work.

Thanks for the report. I’ve sent you an e-mail asking for some more details so we can reproduce and fix the issue. Cheers!
UPDATE: While we are working on a fix to be released in the next update, in the meantime, regenerating your thumbnails resolved the issue for us. You can do this via a plugin like https://wordpress.org/plugins/regenerate-thumbnails/
If that does not resolve the issue for you, please send as much details as possible, including your URL and steps to reproduce to https://jetpack.me/contact-support/
Thanks!

Guys, any news about the language problem as of 3.8.0? Since you implemented the new system, they did not work for me any more. I’m German. https://wordpress.org/support/topic/related-not-translated-any-more?replies=12
