 * The default deployment density of AC- and DC-connected offshore wind capacity is reduced from 3 MW/sqkm

+* Following discussion in `#285 <https://github.com/PyPSA/pypsa-eur/issues/285>`_ we have disabled the

+  A correction factor of 0.854337 is recommended if reanalysis data like ERA5 is used.
