dj console mk4 traktor pro 2 midi mapping upgrade

hi there, ive been having issues with my mk4 for a while, often it takes a few goes to properly register on the controller side with traktor 2 pro. so im looking at upgrading the firmware doftware and midi mapping. however the latest midi mapping for traktor and mk4 says it requires version 2.6.8, but the latest version of traktor as far as i can work out is 2.6.3, so im presuming this is a typo mistake?
