upstart.at states that the Upstart cookbook was released on 2011-03-25, that's right, but that's only a Cookbook (documentation), it also states that the software, upstart 1.2 was released on 2011-03-22 (http://upstart.at/2011/03/22/upstart-1-2-this-sort-of-thing-is-my-bag-baby-released/), so this is consistent with the info from the launchpad page. However, upstart.ubuntu.com seems to be outdated, as it does not show the same information as the other two pages, so I am setting this as confirmed.
