Actually, that's easy since windows does this
automatically. Unfortunately, it needs the binary to be signed. That's
straight-forward enough, although I would need a certificate to do this,
which isn't free (as in beer). The same issue also applies to the
binaries inside the installer (i.e. runemacs, emacs and the rest).

In the ideal world, I would like FSF to do this, after I upload. They
can check the GPG signature, then code sign the installer. But,
runemacs and emacs I would need to sign before packagaing I fear.

That would be harder, and ultimately would just be a big list of
everything that has changed.

That I can do from the changelogs; happy to incorporate this when I can.

Checking for "latest" is a little complex since I need to consider the
correct upgrade paths (so emacs-26 to snapshot is probably
wrong. emacs-27-snapshot to emacs-27 itself is probably
correct. snapshots to pre-releases -- tricky). But yes, can be done.
