Steam Steam Community
1.12.1 1.12.3

Version 1.12.2 is a minor update that was released on August 3rd, 2021. An update for the Making History and Breaking Ground expansions were released alongside this minor release.

1.12.2 is the last feature update to 1.12, and the last feature update to Kerbal Space Program as a whole.

Even though we still may release a minor patch here and there when needed, with this patch we are officially completing the 1.12 update, as well as the sustained development of the original KSP, as we are now shifting gears towards the development of KSP2.
