Breaking changes in 4.0?

[swrobel]

Per the release doc, a major version bump like this would have breaking changes, but I don't see any in the changelog... Is it safe?

Hi @swrobel !

We made the decision in #481 to release those changes in a major release since they changed the return types of a bunch of methods to be Mashes instead of plain ol' ruby hashes.

Overall this shouldn't cause many issues for folks, but we chose to be safe here with the number of libraries that list hashie as a dependency.

Thanks!
