A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Hello fellow comrades! We've been getting very high reviews lately. And now that winter is finally here... Red Matter's first ever sale is live!
