How this is measured

Posts in a game's Steam news feed that Steam tags as patch notes.

News checked every day. Observed since 22 Oct 2026.

An announcement is not a build. Developers can ship updates without a post, or post about several updates at once.
Each check keeps the 10 most recent posts. Quiet games are checked as rarely as monthly, so a very busy feed can have gaps, and posts from before our first check may be missing.
