Prior-free cosmological parameter estimation of Cosmicflows-4
The analysis suggests a Hubble constant value of 75.8±0.4 km/s /Mpc, exacerbating (or independently confirming) the existing "Hubble Tension".

Rising Tension.
Early Cosmicflows-4 result: R. Watkins+co-authors present an estimate of the bulk flow, the average velocity of the survey volume: about 400 km/s. This has an epsilonesque chance of occurring in the ΛCDM model with CMB derived parameters.
