Yeah.... Armory needs to update their site. It makes the version provided here seem sketchy when it isn't available to all Armory users.
Both are signed by the same PGP key. Both bitcointalk.org and the Armory website have always been used to post new versions of this software. So, it might seem like that. But in reality, it's not.
Sure, but let's be honest, when an updated version is only posted on the forum and the main website's version remains outdated, it kind of seems like bush-league.
