Included in the 2020-02-14 release are two new endpoints, designed to provide high-level information about CDISC Library. These endpoints support both JSON and XML media types.

First, /mdr/about returns the URL for on-line API Documentation and Release Notes. It also includes a hypermedia link to a list of the product groups with their most recent update dates, as described below.

/mdr/about
