This document describes about the changes made for the command line version of the package export options.
Why doesn't the Pkg_export tool recognize the -includesourceinfo option anymore since CIS v7.0.3?
This option is removed from the begining in CIS v7.0.3 and -includesourceinfo was replaced with -nosourceinfo instead. Now the default behavior is to include the datasource information and you must opt to not include the datasource info if desired.
You can see the usage change in this example, between v7.0.2 and v7.0.3.
