 - **38_factos_costs** sticky_labor realization: included option to set a labor share target
 - **15_food** changed `anthro_iso_jun22` realisation such that results in case of `exo_diet = 1/0` and `exo_waste = 1/0` are identical until 2020
 - **62_material** Bioplastic demand identical in all scenarios until 2020
+- **30_crop** identical assumptions for bioenergy until 2020
 
 ### added
 - **scripts** added start script which starts an empty model just regenerating a previous run
