Abstract: Systems and methods are disclosed for updating players that run, display, or otherwise use electronically-stored content. Information is included in the content that not only indicates the player version needed to play the content, but also the existence of a newer player version. Content providing such an indication is termed “version-aware content” and allows a player to recognize that a newer player version exists. Version-aware content may be interpreted to provide a user with a message indicating that there is a newer version available. In another example, a player may automatically update based on the version-aware content's indication that a newer player exists. Content created to be compatible with older player versions can be created as version-aware content. Similarly, existing content can be modified to be version-aware content. In both cases, distribution of such content can encourage player updates and thus more rapid proliferation of a newer player version.
