With this release, the Flexible Distribution Grid Demonstrator (FLEDGE) was renamed to Multi-Energy System Modeling and Optimization (MESMO).

• Added new optimization problem object (utils.OptimizationProblem) as main interface for defining optimization problems with functionality to 1) export the standard form for LP / QP, 2) directly interface Gurobi for better performance with large problems.
• Overhead line types can now be defined in terms of conductor data and geometric arrangement (Arif Ahmed).
• Added local-approximation variant for linear electric grid model.
• Added linear model set for electric grid model, which enables defining separate linear models for each time step.
• Added power flow solution set, to obtain power flow solutions more conveniently for multiple time steps.
• Added pre-solve method for DER model set, to obtain baseline nominal power time series for flexible DERs.

• Improved / simplified define_optimization...() methods for most use cases.
• Revised define_optimization...() methods for new optimization problem object.
• Switched from multiprocess to ray for parallel processing for performance reasons.
• Revised documentation structure, overhauled the architecture documentation and added the configuration reference.
