In the process, some other small changes should be noted:
urlStack is now urlHistory, a hash of methods and properties used for history stack management (stack, activeIndex, getActive, getPrev, getNext, addNew, clearForward, and listening Enabled). All these are documented inline and exposed on $.mobile.urlHistory (I'm not sure these will be publicly documented, but just exposed internally for plugins for now).
$.changePage has two argument changes: the "back" argument is now called "reverse"; this results in no change from an end-user standpoint, but reflects the fact that it only reverses the direction of a transition without affecting the internal history stack, and second, a new argument at the end defines whether changePage was called from a hashChange which makes that url open to history menu guessing.
This makes our include model match the include model on the CDN, and allows devs to make use of mobileinit for debugging some of the samples since that must be set up after jquery.js, but before jquery-mobile.
