Which version of SH5 should I get in order to get the latest update?

I have the Steam version of the game, but I know that this version wont allow you to update to the latest version that most of the mods run on. I was going to buy a pc downloadable copy from Amazon (http://www.amazon.com/Silent-Hunter-...ilent+hunter+5) but I wanted to ask the good people here at subsim if this copy would allow me to update to the latest version, or do I have to have the physical copy. I looked around before posting but I couldn't find the answer. I'm sure this has been answered somewhere, sorry if it is a repeat post. Thanks guys!
