Files with the extension '.ris' are understood to contain RIS bibliographic data, which can be parsed to appropriate system attributes in the References group. This improves the handling of references to journal articles and conference proceedings imported from Bookends, Zotero, and other sources of RIS data.
Dragged references hold this information in $ReferenceRIS.
The references type (article, journal, book, etc.) is extracted from the 'TY' field and placed in $RefType. See more on the allowed values for RIS code 'TY'.
Author import: $Authors respects the order of the received source list (previously it was re-sorted in alphabetical order,).
