There were patches for the PC version.
The wiki for the PC version states the latest version is 1.03 which is kinda weird because it's not mentioned on the Ubisoft website.
Either way, by the looks of it, the only things they patched were specific to PC, so it may well be that the PS4 version never received any updates.
