On November 11, 1940, couple of raions were re-designated : Vysotsko-Vyzhnie to Borynia ( village ) and Lavochne-Slavsko ( village ).
In 1750, an Orthodox priest and witnesses confirmed Vlachs didn't exist before around Kupa, Steni njak, Petrova Gora and Slavsko Polje, but only around Hrvatska Kostajnica.
