Ray spent many hours getting both lists consistent as far as the naming of engines are concerned.

The latest CCRL Rating Lists and Statistics are available for viewing from the following links:
http://computerchess.org.uk/ccrl/4040/ (40/40)
http://www.computerchess.org.uk/ccrl/404/ (40/4)
http://www.computerchess.org.uk/ccrl/404FRC/ (FRC 40/4)

Please note that the three lists are updated separately to each other. The 40/40 and 40/4 lists are updated once every two weeks and alternately to each other. The FRC list is updated when a new engine or engine version is being/has been tested.
