- add support for HEAD in resources (patch provided by tpresa)
- fix shell for 1.9.2
- workaround when some gem monkeypatch net/http (patch provided by Ian Warshak)
- DELETE requests should process parameters just like GET and HEAD
- adding :block_response parameter for manual processing
- limit number of redirections (patch provided by Chris Dinn)
- close and unlink the temp file created by playload (patch provided by Chris Green)

Thanks to have a look
