- Driver->prepare() can now take a new Database\Query object as the first parameter - The Query class allows for building a complex query out of a main body, common table expressions, WHERE coniditions, ordering conditions, a limit, and offset - The subscriptionList method is the prototypical example of usage - The experimental articleList method will in time be adapted to use this as well - A generic means of specifying a selection context is forthcoming; this would remove subscriptionList's $folder and $id parameters, for instance
