EcoSys Configuration Features by Release
The EcoSys support site provides a complete list of all the enhancements and bug fixes for each EcoSys EPC release from 7.0.01 onward. This list concentrates on the configuration enhancements and is made available for users who do not have access to the support website.
If you are running on version 6.x and are concerned about the disruption upgrading would cause, K2 recommends you do move to the 7.x platform. You may have to do some minor reformatting to your existing reports, although you might want to do that anyway to take advantage of the latest reporting functionality.
