I host a site which is no longer actively maintained, but for which I still want the active functionality of WordPress for. Since I am not babysitting the site anymore, having to deal with updates is a real hassle, but a necessary one due to security concerns. Well, it's not a hassle anymore. Thanks to Automatic Updater, my site is not happily maintaining itself, updating plugins, and, most recently, WordPress itself without hitch. Great work.
