Revisit these release procedure
Adding TODO: pre-tag test on conda-forge? Adding TODO: publish RCs on conda-forge?
from https://github.com/numba/numba/issues/9410
This task is lighter-weight now. We can commit to doing this for the next release. Will do this for 0.59.1 by tagging an RC and rehearsing the process on conda-forge, but not actually going through the whole RC process.

Configuration (note that we are bad and part of the configuration is initialized outside the initialization function, but that could be fixed): https://github.com/tardis-sn/tardis/blob/master/tardis/montecarlo/montecarlo_configuration.py
Configuration usage (it's also used in more complex/messy functions): https://github.com/tardis-sn/tardis/blob/64df98bf7614988c6d5d8c962d00e9319428aba2/tardis/montecarlo/montecarlo_numba/interaction.py#L316
