Stable releases of the Steam launcher can be found in archive/stable/.
New beta releases appear in archive/beta/ first. After testing, the beta is either promoted to archive/stable/, or superseded by a new beta.
The apt package pool in pool/ only contains the newest stable release and the newest beta. Use the version-numbered releases in archive/stable/ or archive/beta/ if you need a stable URL (in Arch PKGBUILDs, Gentoo ebuilds, etc.) or if you need to scan a directory listing to watch for new releases (in debian/watch etc.).
