+===========================
+Sale Final Customer Address
+===========================
+
+* Adds a boolean field "Final customer" on delivery addresses (contacts with
+  type "Delivery Address").
+* Adds a boolean field "Ship to final customer" on Sales Orders.
+* When enabled, the shipping address field only shows delivery addresses with
+  "Final customer" enabled.
+* When disabled, it only shows delivery addresses with "Final customer"
+  disabled.
+* When creating a new delivery address from the Sales Order, the default value
+  for "Final customer" follows the Sales Order checkbox.
+
