OVERVIEW

This page details the release history of Media Entertainment Core (MEC).

Versioning: Number changes (e.g., 1.2 and 2.4) constitute schema changes. Letter changes (2.3c) are documentation-only changes.

Backwards Compatible means that elements were added, but old elements still exist. Therefore, an old XML document with the new namespace will validate.
