Each node now has two index: nodeIndex and checkIndex. nodeIndex is the index in both the view definition and the view data. checkIndex is the index in in the update function (update directives and update renderer). While nodeIndex and checkIndex have the same value for now, having both of them will allow changing the structure of view definition after compilation (ie for runtime translations).
