Upcoming Release
================
* Allow for more conservative waste heat usage assumptions in district heating using a scaling factor for respective link efficiencies
* In simplifying polygons in :mod:`build_shapes` default to no tolerance.
* Set non-zero capital_cost for methanol stores to avoid unrealistic storage sizes
