I don’t care how this is done, but it would be really great
a) to get informed that there is a new version and
b) to have a place where I can look up if I have the current version installed.
So a short note “I’ve uploaded version 9876.543 that fixes bugs” would be enough. Then I could wait until the new version appears on GOG and modify the first post of this thread.
The problem is that GOG doesn’t tell you that there is a new version (without using Galaxy). You have to login, change to your library and open the “updated games” page. Beside that, I would like to know what has changed to the previous version. That hasn’t to be that detailed like “fixed null pointer exception in module foo.bar”. But it would be great to know that there are bugs fixed or new features (that gives me a reason to replay the game again ).
