For the record,
http://hg.python.org/peps/file/3b67372b39ba/pep-0426.txt is the last
version prior to the switch to JSON, and the summary of differences is
at http://hg.python.org/peps/file/3b67372b39ba/pep-0426.txt#l1263

At that time, I think wheel still had a dependency on PEP 426 -
changing wheels to work with the setuptools metadata was a relatively
late change after we realised it made sense to decouple the two
activities.

Cheers,
Nick.
