I worked with Fran in the past (when I helped with the German localization of Ghost 2.0 and UnMetal) and he is not the kind of guy who would leave GOG standing in the rain. I am sure this is just an oversight. I will contact him as well.

According to fran the update is just about Steam workshop maps. I told him that in his changelog he mentioned balance changes as well ... waiting for a reply.

Oh, that's cool! :)

I told him the same. My exact words were:

"This might have been the main focus but according to your changenotes there's more."

Then I posted the rest of the changelog. He did not reply anymore after this, so I can't say if he's planning to update these or not.

Turok 1 got a big steam update that I don't see on GOG yet.

It's currently only available via Galaxy.

I'm on galaxy and I see no mention of it in the patch notes or anything.

Patch notes are not always up-to-date.
