Sparktank: I just signed in, ready to purchase some more games, and I see a notification that one of my previously purchased games has an update.

But when I went to review the game, Stronghold HD, I didn't see anything showing any sort of update or changelog of what's new.

Is there any way to find out what the update is?
I'd rather not download everything again.

Purchased on Mar 8, 2013
So is there any way to tell what has changed since Mar 8, 2013???
The version I have downloaded for the game is: 2.1.0.4.

I would love to see updates/changelogs in the game section.
Maybe also a tracker for what I downloaded and how many times.
Like a "NEW" button beside items that are updated.

Sparktank: Thank you for the reply!
Since I don't speak/read Polish, I can live with the version I have installed.

Thanks again. :)
