A few days ago, the Cordova team released version 3.5!
There are a whole host of items that were updated, and you can read them in all their glory here.
Some of the bigger items was dropping support for iOS 5 and gaining support for arm64. This will also be the last release with support for Windows Phone 7.
I would expect to see support for it in PhoneGap Build in a few weeks. As always I will be updating ConfiGAP to target this new version shortly as well.
