The new release comes with a number of new features, including a slightly tweaked user interface, support for Macs with Retina displays, and the ability for users to upload and share photos along with their tweets. The app now also supports fourteen new languages, including Italian, French, German, Dutch, Russian, Simplified Chinese, and more.
The good news doesn't stop there, though: It seems that this is more than just a one-time event. Twitter developer Ben Sandofsky has announced--in a tweet, of course--that he will now be working on the company's OS X client full-time, indicating that there might be more improvements and new features coming over the next few months.
Twitter for Mac began life as Tweetie for Mac, and was created by Loren Brichter. Both the iOS and Mac versions of Tweetie were acquired by Twitter when it hired Brichter in early 2010; he departed the company in 2011.
This latest update comes after a long period of silence, during which Twitter for Mac languished, never acquiring many of the features of its iOS counterpart. Numerous rumors had indicated that work on the OS X app had stopped, as Twitter attempted to push more and more desktop users towards its Web-based apps.
Twitter for Mac 2.2 requires OS X 10.6 or later, weighs in at a slender 4.5MB and can be downloaded for free directly from the Mac App Store.
