The code coverage link is also broken.

I would be glad to fix it but can't find that screenshot anywhere on the website. @aladdin-add

it was in readme in the repo: https://github.com/facebook/prepack#status

Not sure how to fix this because it is CircleCI dependent and I don't even know if non facebook people can do it.

What I saw is that it looks like the "latest" build tag is not working properly, because if you try with other builds ids it works.

The "website" issue label should removed imho, not related.
