 Upcoming Release
 ================
 
-* Removed geothermal-sourced heat pumps and fixed previously underestimated costs for geothermal heat source. Recommendation: Use excess-heat-sourced heat pump data for geothermal-sourced heat pumps (only the heat pump part of the costs!) and consult the DEA technology catalogue.
-
-* Removed water-sourced heat pumps, as cost assumptions (based on higher uncertainty range in DEA tables) are a) likely overestimates and b) break pessimistic/optimistic scenarios. Recomendation: Use excess-heat-sourced heat pump data or see DEA data on seawater-sourced heat pumps.

 * Updated DEA Energy Storage data file (technology_data_catalogue_for_energy_storage.xlsx) to the newest version 9 – costs are now given in 2020 currency year.
 
 * Added storage temperatures as a parameter for central and decentral water tanks as well as for pit thermal energy storage.
