Typical gap between builds

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
Earlier Updates| Posted | Update |
|---|---|
| 6 May 2023 | ERSATZ v1.62 (Win + Linux) Patch notes |
| 6 Apr 2021 | Optional Windows Update Adds Russian Language & Bootup Fix Patch notes |
| 16 Oct 2018 | ERSATZ v 1.47 Update |
| 4 Oct 2018 | ERSATZ v1.46 Update |
| 31 May 2018 | ERSATZ v1.45 (Win, Mac & Linux) + The Hidden Chest Video Review 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.
