- several new importers (folder tree, Luhmann, FedWiki, Hypothes.is, Tagged List, Roget, newer Citavi) and
- new exporter (lines CSV),
- new autolayouts (Make Circle, DAG Layout)
- and other layout aids,
- support for close reading,

All the changes only concern advanced uses; the main functionality stays simple and the same as it was.
Note that some new features are currently only available in the .jar download format, not .dmg or .msi.
