Here is what was added/changed in the vanilla of the game:Welsh/English share the LongbowsScottish still have the SchiltronBaltic Group and Finno_Ugric Group have Heavy InfantryAltaic Group and now with Persian share the Horse Breeders (used to only be for Altaic)Bretons added to the Frankish/Occitan/Norman/German Knight ListsIberian Group still has the Fast Horse BreedersItalians still have the PikesRussians still have the Heavy Infantry ArmoriesSaxons and Scandinavian Group now share HousecarlsHungarian and West Slavic Group share HussarsArabic Group now have CamelsByzantine Group now have CataphractsIrish now have GallowglassEthiopian now have Light Infantry Drilling GroundWest African Group use a Free Warrior LodgeSouth Slavic Group now have CavalryDutch now have Urban MilitiaThe Muslim religion also get their own unique Castle Building.I do not have time to compute if every culture is represented or not as I am busy making a quota for my Culture Buildings Mod. Enjoy the list and good luck!EDIT:Here is a Google Doc with a list of ALL current cultures sorted by their groups and what buildings are specific to them. Each letter represents a unique building (so if A is next to English and Welsh that means both share the same unique building). If a Group has a letter next to it that means that the unique building is given out by group and not individual culture.From this research, only the Kurdish culture does not have a building.
