Major changes since the last draft: 1. Metadata-Version is 2.0 rather than 1.3, and the field now has the same major.minor semantics as are defined for wheel versions in PEP 427 (i.e. if a tool sees a major version number it doesn't recognise, it should give up rather than trying to guess what to do with it, while it's OK to process a higher minor version)

So is it possible to bundle several versioned metadata files in order to maximize compatibility? Or does a distribution with 2.0 metadata have to abandon all hope of being compatible with all tools?

Antoine.
