Electronic Arts originally stated that the "Ultima Online: Kingdom Reborn" client would replace the long-standing "Ultima Online" client. As of September 2009, the Kingdom Reborn client has been superseded by a modified version of the KR client, now called the "Enhanced Client". The Kingdom Reborn client no longer works on official shards. The new "Enhanced Client" keeps the rendering engine (including particle effects and light source rendering) from Kingdom Reborn, but not the KR graphics. Support for this client ended to streamline the patch process prior to the release of the expansion.
