In rails 3.0.9 (and maybe earlier) this code no longer works:
//feed.atom.builder
atom_feed :language => 'en-US' do |feed|
feed.title @title
feed.updated @updated
feed.link('href' => 'http://[REDACTED].superfeedr.com/', 'rel' => "hub")
...
end
The exact error is: ArgumentError: wrong number of arguments (1 for 2) with a stack trace of:

This is important for me and to setup a superfeedr Pubsubhubbub as described here. I need to get a <link rel="hub" … > tag into the atom feed but feed.link no longer works like it used to due to the method being removed from atom_feed_helper.rb. How can I get this link tag to show up again?
I believe you used this gem which seems a bit old, and since Atom is just a flavor of XML, it may be easier to just write the feed yourself anyway, using the answer given there.
