3.0 lacks markdown.version

[keenerd]

In 2.6.11 (and older versions) one could import markdown; markdown.version and this is no longer present in 3.0: AttributeError: 'module' object has no attribute 'version'

Please add this to the release notes if it was intentional.

This is a duplicate of #709.

Apologies. Didn't think to dig through the recent PRs.
