Just saw three of my games get updates, BloodRayne, Spellforce: Platinum, and Massive Chalice. Two of those are failry old, so I'm curious what changes could have been made.

Is there a way to see what those updates?

In the website under the game in your library, click more, then select change log.

Just to avoid confusion. In many cases you won't get a changelog at all (I know that BloodRayne i.e. did not receive a changelog since I own it myself). These are usually installer maintenance updates only but unfortunately sometimes GOG just did not post a changelog even though the game HAS been updated for real. This might happen because they did not receive a changelog or because they just forgot or something broke. It#s one of many complaints users are posting here often.

OK, thank you.

Just to mention also, folks here keep a running thread of recent change logs here:

Hope this helps

It seems lot of classic (ie old) game's installers were just updated (I got 25 update notices) with no changelog so they're just repackages and any other minor changes (like versioning system changes, advertising banners) to installers themselves. No game file changes.

Good to know. Thank you for the information. :)
