First up, lots of things have been re-worked in the back-end to future proof it for upcoming devices, this includes support for the recently released BlackBerry Passport. As well as that, Web Design Cheat Sheet has also been tweaked for BlackBerry 10.3 so will run smoothly for those running OS 10.3.
The search option has also be included in this latest release and if you're running BlackBerry 10.3 that search will be found slap bang in the bottom centre as a 'Call to Action' icon. Definitely some nice additions to the app. If you haven't updated already, look out for it.
Web Design Cheat Sheet is available for all BlackBerry 10 smartphones and is free download. There are in app purchases available unlock other features within the app, such as the HTML/CSS editor, which is pretty handy.
