Release Notes
PyPSA-Eur 0.2.0 (TBD)
The optimization is now performed using the pyomo=False setting in the :func:`pypsa.lopf.network_lopf`. This speeds up the solving process significantly and consumes much less memory. The inclusion of additional constraints were adjusted to the new implementation. They are all passed to the :func:`network_lopf` function via the extra_functionality argument. The rule trace_solve_network was integrated into the rule :mod:`solve_network` and can be activated via configuration with solving: options: track_iterations: true. The charging and discharging capacities of batteries modelled as store-link combination are now coupled (#116).

PyPSA-Eur 0.1.0 (9th January 2020)
This is the first release of PyPSA-Eur, a model of the European power system at the transmission network level. Recent changes include:
Documentation on installation, workflows and configuration settings is now available online at pypsa-eur.readthedocs.io (#65).
The conda environment files were updated and extended (#81).
The power plant database was updated with extensive filtering options via pandas.query functionality (#84 and #94).
Continuous integration testing with Travis CI is now included for Linux, Mac and Windows (#82).
Data dependencies were moved to zenodo and are now versioned (#60).
Data dependencies are now retrieved directly from within the snakemake workflow (#86).
Emission prices can be added to marginal costs of generators through the keyworks Ep in the {opts} wildcard (#100).
An option is introduced to add extendable nuclear power plants to the network (#98).
Focus weights can now be specified for particular countries for the network clustering, which allows to set a proportion of the total number of clusters for particular countries (#87).
A new rule :mod:`add_extra_components` allows to add additional components to the network only after clustering. It is thereby possible to model storage units (e.g. battery and hydrogen) in more detail via a combination of Store, Link and Bus elements (#97).

Hydrogen pipelines (including cost assumptions) can now be added alongside clustered network connections in the rule :mod:`add_extra_components` . Set electricity: extendable_carriers: Link: [H2 pipeline] and ensure hydrogen storage is modelled as a Store. This is a first simplified stage (#108).

Unknown interpreted text role "mod".
Logfiles for all rules of the snakemake workflow are now written in the folder log/ (#102).
The new function _helpers.mock_snakemake creates a snakemake object which mimics the actual snakemake object produced by workflow by parsing the Snakefile and setting all paths for inputs, outputs, and logs. This allows running all scripts within a (I)python terminal (or just by calling python <script-name>) and thereby facilitates developing and debugging scripts significantly (#107).
