adaliabooks: Actually... it's quite possible a lot of those updates were for Galaxy related stuff (like supporting cloud saves) and so weren't notified on the site because they are only relevant if you are using Galaxy.
timppu: Do they change the installer versions too for Galaxy cloud save support and stuff? I know in the past they have changed some installer versions to be "more Galaxy-compatible", ie. irrelevant updates to people who don't use Galaxy at all, but relevant to people who might want to import their manually installed GOG games to Galaxy.
I don't think they change the installer version, but I imagine they would update the files (I'm sure they have done this in the past), so the 'desktop' version would still work and be compatible with Galaxy just in case someone starts using Galaxy later or happens to download a game from the website instead of installing it with Galaxy.
