(Original issue title: Inconsistent crate info display (mixing versions) )

About: https://crates.io/crates/petgraph

The most recently released version of petgraph is 0.2.10.

The greatest version is petgraph 0.4.5.

This is inconsistent, it should show all the information from the same version:

• Documentation is taken from 0.2.10, a version that is not visible anywhere on the page.
• Categories (or the lack there of) seems to be taken from 0.2.10
• Dependencies are taken from petgraph 0.4.5.
• Last Updated is taken from 0.2.10

Unknown because they are the same across versions: License, Authors, Keywords, Repository, etc.
