 All Docker names are suffixed with a hash derived from the file path (to allow concurrent usage on things like CI machines) and a version number.  When the version number changes all state is cleared and clean build is started.  This allows the build infrastructure to be changed and signal to CI systems that old artifacts need to be deleted.
