This is what IntelRobert said :
Crosswalk 8 (beta build in XDK) includes apache cordova 3.5.0. Crosswalk team will need to update, test, and then we will need to update our servers. This normally takes about a week, but I haven't gotten a firm date on how long it will take. After that is done, you would just need to build again and republish.
This problem affects most users of cordova/phonegap.
And Tekniko, that's not how these things work.
