This release is mainly the work of Nathan Weizenbaum and Chris Eppstein, with a bunch of contributions from other Rubyists. I don't think Hampton worked on this release, and he hasn't been active in Haml/Sass development for a while. That's no knock on Hampton; there's just a tendency to give most of the credit to the initial author of anything (think Perl, or Linux), and in this case other people deserve a bunch of credit, too.
