I think the binary release links should point to:
https://adoptopenjdk.net/upstream.html

It would remove the need to update yet another page when releases are
being cut.

Or perhaps we should create a wiki page detailing which build the user
is supposed to download for a specific release and explain how to
verify the GPG signature.

Thoughts?

Thanks,
