TouchKit 2.1 Upgrade Issues

I have tried to update my application to TouchKit 2.1 and well, it won't compile the widget set. Are there any instructions to clarify how to upgrade appropriately? Here is what I get when I try to build my project with the new jar:

Computing all possible rebind results for 'com.vaadin.addon.touchkit.gwt.client.TouchKitOfflineApp'

Any suggestions?

Hi,

Update you Vaadin dependency to latest 6.7.8. That will also make Android (3.x +) users lives much easier as their scrolling works. It was broken due broken scrollTop implementation in Android browser.
