Oops, I knew I forgot something... redirects! Will fix that soon :)
We removed the fancy HTML for all but latest, as it simplified the infrastructure a lot. So the URL you found replaces it. I will make the old URLs redirect to this new location. Not as fancy, but contains all the required bits and pieces.
If you have a good use case why older versions should have a fancy page, feel free to let us know. Always a change we readd it :)
