Valve has released a SteamPipe version of L4D2 and advised us that this update will become required on Monday. In order to reduce the time that will be required for Monday's update, we are scheduling the SteamPipe changeover to occur on Friday morning, starting at approximately 12:30am PDT. This will be handled like a regular game update, but it will take longer, due to the size of Valve's changes up to two or three hours for some machines, with servers offline for much of that.
