So the new version of the regular game no longer includes those modifications.
Thats not true.
2 of the 4 changes to the action spaces in the old edition are still in the new edition. Only they are not printed on the backside of the board. Instead the game comes with 2 extra tiles to cover the respective spaces with (starting player + food and build 1 stable for 1wood + bake bread).
The Day Laborer space remains unchanged, instead of providing 1 food + 1 building resource as in the old edition.
But the game comes with 2 extra tiles to use in addition to the regular board. They can be used in the family game or in the regular game.
One can be used in a 2 player game and has 4 different action spaces, of which only 1 can be used.
The other one can be used in a 3 or 4 player game and provides 2 additional action spaces.
So its not 100% the same, but it does support playing without cards in a slightly different way.
