WordPress’ Matt Mullenweg just announced that the WordPress.com interface and all the blogs hosted on the site are now optimized for high-density displays like the ones found on Apple’s new iPad and Retina MacBook Pro. Through JetPack 1.6, which also launched today, users with self-hosted WordPress sites can also enable the same functionality.
The arrival of these high dots-per-inch (HiDPI) devices took many developers by surprise and while many Mac apps, for example, have already been optimized for Retina displays, most developers are still playing catch-up. Things are even worse on the Web. As Mullenweg notes, most web sites “don’t have high-resolution equivalents of all their graphics to take advantage of the new screen, so they get “doubled” and look fuzzy, they stand out like a sore thumb.”
With this update, WordPress.com will now serve high-resolution images on its blogs for all users who can see them. To do this, says Mullenweg, WordPress will take the images its users have uploaded and then sized down to fit their theme and serve them at a more Retina-optimized resolution. The WordPress team also optimized the dashboard, reader and all of its own sites to take advantage of these new high-density displays.
As for self-hosted blog, WordPress plans to integrate all of these Retina improvements into its upcoming 3.5 release, but for the time being, users will have to enable these features through JetPack. Besides Retina support, the latest version of JetPack also introduces Pinterest share buttons.
Gravatar, too, is now Retina-ready and, as the company puts it, its users’ profile images will now “be looking extra sharp to anyone who views [a] Gravatar profile or Hovercard from a device like the iPhone 4.”
