I would like to start my first playthrough with the game and would like to have the latest patch for that.
On steam the game is already on version 1.03, while the GOG version seems to be stuck on 1.01.

Could the developers please make the lastet patch also available on GOG.

Ok, patch arrived 4 days after steam.
Changelog on GOG has not been updated.
Versioning in GOG Galaxy is different than on steam.
Steam calls it "hotfix 1.0.3" while GOG calls it version "1.15". Ingame it shows Hotfix 1.0.3 RC1.
