A post on Steam News announces a new automatic update for Portal, Valve's first-person puzzle platformer. The patch notes don't really make sense, saying the update: "Changed radio transmission frequency to comply with federal and state spectrum management regulations," hinting that something interesting may be on the way. Shacknews notes the Steam Users' Forums are puzzling through this, noticing a new Portal Achievement has been added, as well as some Morse code audio files that seem to indicate GLaDOS is, well, still alive.
