v0.4.0

Frequenz Microgrid Component Graph Library Release Notes

Upgrading

• This release updates the frequenz-microgrid-component-graph rust crate version to 0.5. ComponentGraphConfig is restructured to match: the six per-category prefer_X_in_Y_formula flags are replaced by a global prefer_meters_in_component_formulas plus per-formula overrides via the new FormulaOverrides class. Also exposes the new steam_boiler_formula method, and renames battery_coalesce_formula / pv_coalesce_formula to battery_ac_coalesce_formula / pv_ac_coalesce_formula.

• ComponentGraphConfig.__init__ is now declared as keyword-only in the type stubs (the runtime was already keyword-only, so positional calls were already failing at runtime).

• The per-category preference flags inverted polarity: where the old flags selected the device, the new override entries select the meter. E.g. ComponentGraphConfig(prefer_inverters_in_pv_formula=True) becomes ComponentGraphConfig(formula_overrides=FormulaOverrides(prefer_meters_in_pv_formula=False)).
