Version 3.0.2 is the direct result of community feedback about the migration of date sub-records attached to agents. The updated migration will create an equal number of new structured date sub-records from the original date sub-records and do some parsing of date expressions in range dates into begin and end date expressions. If you previously upgraded to 3.0.0 or 3.0.1, this migration will be skipped.
This version also fixes a bug uncovered with the spreadsheet importer for adding digital objects to existing archival objects.
