v0.10.4 (Anticipated March, 2024)

Enhancements

Added the Huld PV model used by PVGIS (1940)
Added :py~pvlib.iotools.get_solrad for fetching irradiance data from the SOLRAD ground station network. (1967)
Added metadata parsing to :py~pvlib.iotools.read_solrad to follow the standard iotools convention of returning a tuple of (data, meta). Previously the function only returned a dataframe. (1968)

Fixed an error in solar position calculations when using :pypandas.DatetimeIndex with unit other than 'ns' (1932). The following functions were affected:
- :py~pvlib.modelchain.ModelChain and :py~pvlib.solarposition.get_solarposition with the nrel_numpy and nrel_numba methods
- :py~pvlib.solarposition.spa_python
- :py~pvlib.solarposition.sun_rise_set_transit_spa
- :py~pvlib.solarposition.nrel_earthsun_distance
- :py~pvlib.solarposition.hour_angle
- :py~pvlib.solarposition.sun_rise_set_transit_geometric
:py~pvlib.modelchain.ModelChain now raises a more useful error when temperature_model_parameters are specified on the passed system instead of on its arrays. (1759).
:pypvlib.irradiance.ghi_from_poa_driesse_2023 now correctly makes use of the xtol argument. Previously, it was ignored. (1970, 1971)

Improved references and description for :py~pvlib.irradiance.get_ground_diffuse. (1953)
Fixed broken URLs in various places. (1957, 1960)
Clarified documentation for :py~pvlib.irradiance.get_ground_diffuse. (1883)
