AB  - We review lattice results related to pion, kaon, D-meson, B-meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communities. More specifically, we report on the determination of the light-quark masses, the form factor f<sub>+</sub>(0) arising in the semileptonic K → π transition at zero momentum transfer, as well as the decay constant ratio f<sub>K</sub>/f<sub>π</sub> and its consequences for the CKM matrix elements V<sub>us</sub> and V<sub>ud</sub>. Furthermore, we describe the results obtained on the lattice for some of the low-energy constants of SU(2)<sub>L</sub>×SU(2)<sub>R</sub> and SU(3)<sub>L</sub>×SU(3)<sub>R</sub> Chiral Perturbation Theory. We review the determination of the B<sub>K</sub> parameter of neutral kaon mixing as well as the additional four B parameters that arise in theories of physics beyond the Standard Model. For the heavy-quark sector, we provide results for m<sub>c</sub> and m<sub>b</sub> as well as those for D- and B-meson decay constants, form factors, and mixing parameters. These are the heavy-quark quantities most relevant for the determination of CKM matrix elements and the global CKM unitarity-triangle fit. We review the status of lattice determinations of the strong coupling constant α<sub>s</sub>. Finally, in this review we have added a new section reviewing results for nucleon matrix elements of the axial, scalar and tensor bilinears, both isovector and flavor diagonal.
