Generated using TypeDoc
An interface that describes an object representing an available update to the current application - this update may have several available patches from which one must be selected to download and install, for example we might select a binary difference patch first and attempt to apply that, then if the application process fails fall back to downloading a complete file-replace patch. This object also contains information about the update that the front end and other application services can use to learn more about what is going on.
