It went from 1.9.42 to 1.9.5. This means users of older versions will not get updates. What is worse, there was a notorious security breach at WordPress.org last summer affecting three popular plugins, including WPTouch 220.127.116.11 and 1.9.20. Those infected versions will not get updates.
Developers, please revise your numbering to 1.9.53 or something that works. It is currently 18.104.22.168.
