Looking at the [0.22 release notes](https://github.com/jnunemaker/httparty/releases/tag/v0.22.0) it's not clear to me which changes are breaking changes. If there are breaking changes, could you please annotate them? If not, may I suggest adding a line like "No breaking changes" or "No changes to public API"? In SemVer, `0.x.x` libraries are allowed to make breaking changes at any time, so documentation like this will be very helpful. Thanks!
