We report an improved measurement of the free neutron lifetime τ_n using the UCNτ apparatus at the Los Alamos Neutron Science Center. We count a total of approximately 38×10^6 surviving ultracold neutrons (UCNs) after storing in UCNτ's magnetogravitational trap over two data acquisition campaigns in 2017 and 2018. We extract τ_n from three blinded, independent analyses by both pairing long and short storage time runs to find a set of replicate τ_n measurements and by performing a global likelihood fit to all data while self-consistentl
