"CD now supports dynamic settings. When this option feature is enabled, one or more CD settings can change automatically in response to player count and wave number (that is, how far the current game has progressed from beginning to boss). When any dynamic settings are active, they run automatically, without the need for user intervention (though they can be turned off at any time with a chat command). To make these changes transparent, the new and old values of dynamic settings are printed to chat every time a wave starts."
