The Indie Stone has released the 42.22.1 pre-release hotfix for Project Zomboid on PC. It’s a small, behind-the-scenes update focused on security and housekeeping rather than new gameplay.

The developer says the update shouldn’t break saves. If you hit a bug, it asks you to confirm you can reproduce it on a fresh save with no mods installed before reporting it.

Technical and debug changes

  • Fixed a vulnerability related to eMudhra digital certificate validation.
  • Added integrity checks for the Java Runtime Environment (JRE). If something has modified it, the change will show up in the version watermark.
  • Updated the third-party software licence acknowledgements in the credits and licence documentation.

Discussion of the update is pinned on the Project Zomboid discussion forums, according to The Indie Stone.
