Update now link in old TBB does not point to latest version

Following the discussion on https://twitter.com/dcuthbert/status/464068236258967552, it sounds like the "Update now" link in an old version of the Tor Browser Bundle points to an old update instead of the latest version. This link may have been hardcoded to point to the bundle that, at that point in time, was the latest version, but it means that someone who tries to update a six month old OS X bundle will be taken to the download page for 3.6, instead of 3.6.1 (see the twitter.com link for a screenshot).
