  We review the status of neutrino mass constraints obtained from cosmological
observations, with a particular focus on the results derived considering Cosmic
Microwave Background (CMB) data by various experiments (Planck, ACT and SPT),
Baryon Acoustic Oscillation (BAO) determinations and other late-universe
probes. We discuss the role played by priors and parameterizations in the
Bayesian analyses, both at the time of determining neutrino masses or their
ordering, and compare cosmological bounds with terrestrial constraints on both
quantities.
