Archive Button

According to this bug, there should be an official Archive button zimlet included in v8, but I'm not seeing it in the latest version. Does anyone know where I can get it? There's an Archive zimlet in the Gallery, but it's 3rd party.

Does anyone have a list of the standard zimlets that come with Zimbra these days? The Archive button was a big reason for upgrading to v8, I need it and my clients need it.

Thanks,
Adam
