From Steam’s client network, last checked . Builds before 21 Oct 2026, when we started watching, aren't listed. Patch notes are the developer’s update post from an hour before to a day after the build. Not every build gets one. How we count
| Posted | Update |
|---|---|
| 21 Oct 2026 | v1.5.8 Bug Fixes Patch notes |
| 19 Oct 2026 | Bug Fixes and Active Skill Cost Adjustments Patch notes |
| 15 Oct 2026 | Version 1.5.2 Update Patch notes |
