How can I tell if my copy of Amnesia has the latest patch?

[Carnivean]

Simple question. I downloaded mine from Amazon (it's not on Steam) so i don't know if it's actually patched. I know the latest patch was a few years ago, and I wanna make sure I have it. I've looked in program files and haven't seen anything indicating a patch file. No option for patch notes anywhere as far as I can see. Can anyone direct me?

Take a look on the game official page, or at Frictional blog, maybe there's a download or some info on what's the latedt version.
Edit: i found a link in the Frictional Forum, hope it's useful
