Thanks for the PR!

Thanks! I'm a little hesitant to change the primary URLs in a way that substitutes main and master for a commit or tag because it would mean they would no longer automatically stay up to date, which is a behavior that I think some authors intentionally depend on. But those cases, I'll definitely be able to accept adding those new URLs that include a tag in the versions field. The rest of the changes look great.

I looked through some of the links and of the ones I checked, they all 404'd. This is an improvement! I take back what I said before

@hyperupcall the JSON error is fixed now, perhaps this could be merged per your earlier comment?
