As usual, this update comes with a number of bug fixes and improvements. 3.0.1 now includes Google Voice typing, which performs really well for short sentences in Android 4.0 (Ice Cream Sandwich), and performs really well in general in Android 4.1 (Jelly Bean).
Swiftkey has also fixed the “doubledouble” issue that we experienced with the previous version: when using backspace, the whole text could be deleted at once – unintentionally. Oops. Finally there are a couple of fixes specifically for the Samsung Galaxy S3. For a full change log, check on the Swiftkey site and download from Google Play.
