Upcoming Release
================

* Added option to model n largest district heating systems (according to demand in #1516) explicitly. Enable via ``sector: district_heating:
subnodes: enable: true``.

* Remove snakemake's slurm plugin from windows installations (https://github.com/PyPSA/pypsa-eur/pull/2009).

* Added Xpress solver configuration options (``xpress-default`` and ``xpress-gpu``) with barrier method settings optimized for large-scale linear programming problems.
