  "abstract": "We report on the calculation of heavy-to-light form factors at $\\mathcal{O}(α_s^3)$ and on selected phenomenological applications in inclusive $B$-decays. After outlining the loop calculation, we extract the hard function in $\\bar B \\to X_s γ$, and discuss our recent progress and preliminary results for the N$^3$LO corrections to partial decay rates in $\\bar B \\to X_u l \\bar ν_l$, important for the inclusive determination of $|V_{ub}|$. In particular, we establish relations for heavy-quark parameters in the shape-function scheme to four loops and improve a particular model of the $B$ meson shape-function.",
