 **New features and functionality**
 
+* option for BioSNG (methane from biomass) with and without CC is added
+
+* option for BtL (Biomass to liquid fuel/oil) with and without CC is added
+
 * Units are assigned to the buses. These only provide a better understanding. The specifications of the units are not taken into account in the optimisation, which means that no automatic conversion of units takes place.
 
 * Option ``retrieve_sector_databundle`` to automatically retrieve and extract data bundle.
