Here is the latest report that WordPress.com have announced about the new update and now it is for retina display as well. This was firstly reported by The Next Web and they claimed that ”No details on when we’ll see this come to WordPress.org but there is a plugin available in the mean time which will ensure all images uploaded going forward are Retina ready.”
If you’re a Jetpack user you can get access to the retina update for your self hosted WordPress blog today!
Gravatar has also been given an update to support Apple’s new Retina display. To reap the benefits however you’ll need to upload a larger image, we suggest doing that now.
What’s more however, with the update, Gravatars can now be as large as 2048px, incredibly large, and usable across all devices, Retina supported or not.
According to Matt Mullenweg on this update, All of our sites updating them to take advantage of this new capability, often crafting new icons and graphics by hand. (Go by an Apple store and check out WordPress.com if you want to get a taste of it, but I warn you it’s hard to go back.)
But for you guys we can go a step further. All of your blog posts will now serve high-resolution images for users that can see them, at least the images that we host. Since we create all images dynamically on the fly, what we do is if you’ve uploaded a higher resolution photo and sized it down, we’ll serve a double-size so it looks super sharp to those visitors — they’ll think you’re ahead of the game.
