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

Builds come from Steam’s client network, players from the Steam Web API every few hours. Steam gives no count for an app nobody can launch. How we count
