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 |
|---|---|
| 11 Apr 2024 | UPDATE 2.5.0 | BIG NEWS Update |
| 7 Dec 2023 | UPDATE 2.0.5 | COLLECTIBLE CARDS Update |

| 11 Aug 2023 | UPDATE 1.2.2 | A DELIGHT FOR THE EYES Update |
| 9 May 2023 | UPDATE 1.2.1 | SAVING ISSUES SOLVED Update |
Steam keeps no record of past build numbers, so before 21 Oct 2026 a game’s update history comes from its own Steam news: posts tagged as patch notes, and untagged posts that plainly announce a patch or a released update. Older posts are still being read in, most played games first.
