Hello Kiriaki,

The "dc.date.issued" field is now only auto-assigned if you enable the
"Initial Questions" page and select that the item is "unpublished" (i.e.
not previously published before).  This new behavior is described here:
https://wiki.duraspace.org/display/DSDOC6x/Metadata+Recommendations#MetadataRecommendations-RecommendedMetadataFields

The behavior was changed in DSpace 4.0 because of complaints about
incorrect/inaccurate dates in Google Scholar and Google search results.
Both of those search engines based their results off our "dc.date.issued"
field, and when that field was auto-assigned, it sometimes resulted in very
odd search results in Google.  See these two old tickets for more details:
* https://jira.duraspace.org/browse/DS-1481
* https://jira.duraspace.org/browse/DS-1745

I hope that helps,

Tim
