The updater currently browses FTP, and there=E2=80=99s no way to browse an =
HTTP
directory (because HTTP is not a file transfer protocol).

So we need a way to list the latest releases somehow.  If they publish
JSON, XML, or some other structured info format, that=E2=80=99s fine too.  =
But
HTTP alone is not good: we=E2=80=99d have to infer the information from HTML
pages, which sounds fragile.

Could you check what methods they offer to get updates?
