We present an update for results on B-meson semileptonic decays using the highly improved staggered quark (HISQ) action for both valence and 2+1+1 sea quarks. The use of the highly improved action, combined with the MILC collaboration's gauge ensembles with lattice spacings down to 0. 03 fm, allows the b quark to be treated with the same discretization as the lighter quarks. The talk will focus on updated results for B (ₒ) D (ₒ), B (ₒ) K scalar and vector form factors.
