JSON Light support in REST SharePoint API released

The REST SharePoint API has been an extremely popular way for Office 365 developers to work with SharePoint sites, lists/libraries, and list items/documents. One of the big bits of feedback we got from developers using the REST SharePoint API was about the payload of the data that was returned. Our response was to add support for JSON Light. JSON Light is an open standard that allows developers to provide in the header of the request how much metadata is returned.
