# the sole reason we are using nightly at the moment is to use the portable_simd feature.
# that is, i am not trying to chase "bleeding edge" features in general. as such, i don't
# necessarily see a reason to keep using whatever nightly version is the latest, and would
# prefer stick with versions that appear to be stable and just periodically do manual updates
# here to get *some* peace of mind in terms of build stability.
