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
