Hello again lexluthermiester,
gog.com store pages don't show patch notes for games. You can either access them via the gog launcher, the BSG launcher or from either the gog forum channel for BSG or the Slitherine Forum for BSG. https://www.gog.com/forum/battlestar_galactica_deadlock#1551350422 http://www.slitherine.com/forum/viewforum.php?f=469
Also, there have been several new updates since the September release your original post referred to, all of these release notes can be found in the above two forums (or in the changelogs from either launcher).
I hope this helps.
Sorry for the delayed response.
I'm afraid you are incorrect on that point. Change logs are shown in the GOG main website product pages. Most of the titles in my library show them and in enough detail to be informative.
However, thank you for the links as that was helpful.
EDIT; After looking, it seems the feature is now being used. Thanks for doing that, it's very helpful to know what updates are changing/fixing.
