Wartales remastered modclasses question

Are the classes in the Wartales Remastered mod just renamed/tweaked versions of the vanilla classes or are there additional classes(completely new) on top of the vanilla ones? I havent been able to find a definitive list of the classes or changes and only know some at least were renamed. Considering trying the mod out soon and seeing if I sort of pre plan a company but not being able to put eyes on a class list or what all the vanilla classes' mod renames are makes it a bit hard to properly pre plan a bit.
