Upcoming Release
================
* Group existing capacities to the earlier grouping_year for consistency with optimized capacities.
* bugfix: installed heating capacities were 5% lower than existing heating capacities
* Include gas and oil fields and saline aquifers in estimation of CO2 sequestration potential.
