What are the fixes in 5.2.2? If I am running 5.2.0, will it benefit me to upgrade to 5.2.2? The migration documentation shows upgrading from 5.X to 5.2.X.
You will find that information in Release Notes for EEM 5.2.1 and 5.2.2.
EEM Windows 7 support, fixed localization issues, added some smart card support, etc.
