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(s) → D(s), B(s) → K scalar and vector form factors.
