A new version of SwiftKey X has been released to private beta testers, and it brings quite a few improvements. Chief among them: the ability to learn from your blog via RSS - certainly a nifty feature. Other highlights include better error reporting, general performance improvements, and a number of bug fixes. The update also brings a new novelty feature in the form of the "My typing heatmap," which keeps track of keystrokes and displays a "heatmap" of the keyboard.
