Core Keeper Codex

Patches and updates

Core Keeper's update feed. The build this site is generated from is 1.2.1.5 (build 23543502, 2026-06-08).

How freshness works here

The published branch's build id is checked against Steam. When it changes, the server package is re-downloaded and every page on this site is regenerated from the new files. That is why each page states the version it was verified against — a number without a version is a number you cannot check.
