An uninstall function has been added which removes the fields from the line items. The fields on the line items names have changed. If you are using alpha1 or alpha2 you should completely uninstall the module after downloading the new version then re-enable it.
The first stable version of field validation 7.x-1.0 after 1 years later. Maybe this is the last stable version of 7.x-1.x.
