A modified version of the Kingdom Reborn client, renamed as the "Enhanced Client", was introduced as part of the Stygian Abyss expansion. It was released as an open beta in July 2009. Changes included enhanced macro abilities, a more configurable interface, changes to the mapping system, and graphical improvements. The enhanced graphics of the Kingdom Reborn client had been retired in favor of lower resolution original graphics that more closely resembled the original 2D client. This graphic set was based on the Third Dawn client and was previously available in the Kingdom Reborn client as optional original graphics.
