YAML spec for Change logs

Over on use.perl.org, Brian Cassidy wrote about a YAML-formatted changelog he happened across:

This makes total sense -- Machine parsable high-level changelogs. I'd love to see a spec created for this. A quick poll of #perl-qa shows that some other folks agree. I searched around but couldn't find any existing specs -- any takers? :)

Later, Roland Giersig takes up the challenge with a first attempt at a spec.

I must say, I'd be all in favour of machine-parsable changelogs. It'd make CPAN Watch much more automatable.
