In terms of the package update, you need to update not only the Godeps.json but the package source directory, i.e. Godeps/_workspace/src/github.com/kardianos, in order to be able godep to use it. In addition, we should consider storing the third party packages into vendor directory instead of Godeps/_workspace in near future.
