Support uploading/displaying changelogs.

I'm not sure what this would look like, but it would be useful to be able to see what's changed.

(I could also imagine a cargo diff foo 1.0.3 1.3.2 that downloads/displays the changelogs between those versions.)

I would much prefer to have a changelog in Cargo.toml, which is then parsed by cargo or rendered by crates.io

Here’s a suggestion for a small change that could help a lot: add a changelog field to the crate metadata, similar to homepage, repository and documentation. Crates.io would include a link to the changelog under the “Links” section, similar to the other fields.

People could link it to a changelog.md file in a repository browser such as GitHub, or to a dedicated page on a project site.

As a user of a crate (as opposed to when I am still deciding on whether to use a crate), the two things for which I most often visit a crate page are the docs and the changelog. A direct link could save a click and page load (assuming the changelog is linked from the repository page).

Discussion of this should now happen on RFC 2129, and if that is accepted, it'll get its own tracking issue, so I'm going to close this one.
