Now that 0.5 is released, there are two update servers. One is for stable servers and the other is for development servers. The stable version contains all the database changes at the time of the last major release. The development version contains the latest database changes since that release. If you are using the latest code from SVN then you will need to change your LoginServer.ini file's update server port to 9102. Otherwise it will be using the stable database updates (which won't change until the next release).

So there are 2 update servers running on 2 different ports? So all I need to do to change from one to the other is just change the port...
