This build is to make some updates to the new Intel XDK project format (new to this beta cycle, and currently opt-in from the Cordova export options dialog). Hopefully it should fix several issues users were running in to when using the new format with the latest release of the Intel XDK. In particular it should better support third-party Cordova plugins referencing GitHub repositories, and fix iOS and Windows builds.
We now also enable Crosswalk automatically for Intel XDK builds the same way we do for PhoneGap Build: if you specify a minimum Android version below 5.0, Crosswalk is enabled, otherwise for Android 5.0+ it is disabled (since Android 5.0+ has a good system webview which can generally run HTML5 games fine). When Android 5.0+ has enough market share for your purposes you can therefore opt-out of the Crosswalk APK size overhead (~17mb) simply by setting the minimum Android version to 5.0 when exporting. Eventually when Android 5.0 has enough market share, we will make this the default setting so you get small APKs by default (and then you can opt-in to Crosswalk and its APK size overhead if you still want Android 4.x support).
We'd love it if you could show your appreciation of it by retweeting and sharing it on Facebook and Twitter!
