The issue #1 prompted a roll change of this loader and version 1 has now been depricated.
Version 1.x the loader was a more complete pre-minification solution, overlapping the functionality of ng-annotate. Following version 2 this loader acts as a pre-processor to ng-annotate for the purpose of migrating annotations. Overall there should be no capability gap as a result of the change.
Please comment on this issue if your use case cannot suffer migration to the "ngInject" directive prologue annotation syntax.
