According to the official Steam Community Patch Notes, this update focuses on critical bugs that hindered long-term gameplay:

Resolved issues where certain context menus would stay stuck on the screen or fail to register clicks during high-stress EVA maneuvers.

Open the Epic Games Launcher , go to your Library , and ensure "Auto Update" is toggled on for Ostranauts.

If you purchased the game via Itch.io, log in to your account and download the latest build manually from your purchase page.

While this hotfix is compatible with most v0.10.x save files, it is always recommended to back up your save data before updating, as the complex physics simulation in Ostranauts can occasionally react unpredictably to code changes.

Corrected a bug where airlocks would occasionally fail to cycle correctly, leading to unexpected vacuum exposure. How to Download & Install
