Egyptoon - please see the previous posts I've made. Intel XDK updates are independent of Crosswalk updates, builds, etc. Keep in mind, the XDK is an IDE that provides an immense amount of features outside of just "builds". Also, Crosswalk updates come independently of XDK updates.
We are in face to face meetings (most of the team) in Santa Clara this week. I hope to have something to report next week on the CW11/12 front.
