US Patent 7788662 Automatic upgrade of pluggable components

When a component is to be loaded or executed, the version of the component to be loaded may be compared with available versions of the component. If an upgraded version of the component is available, the upgraded version of the component may be enabled to dynamically and deterministically update itself. The component may be an object in an object model. The upgraded version of the component may update itself by calling an update method. The component may be upgraded with minimum user intervention, dynamically as the object is loaded.
