When using the freerouter, where is the place to define so called “costs” or weighting for certain features? Like telling the router to avoid vias ?
Freerouter is not part of Kicad. It would be best for you to ask about Freerouter on the Freerouter site.

I had a short look at:
The oldest version is 1.2.43 and has file dates of 2015-02-05 and the most recent version is 1.3.1 dated 2017-10-27. Glancing though the changelog, I see mostly small maintenance things and some menu changes.
I think java enthusiasts had a mission to update code as the old stuff got phased out. I think someone converted to the new code but never really updated the workings.
