We report an update of the NNLO ABMP16 PDFs aimed to include recent
data on the Drell-Yan process, single- and pair-production of the top
quarks at the LHC, and the heavy-quark semi-inclusive DIS production with a
main focus on the small-x PDFs. The parameters of QCD Lagrangian,
strong coupling constants and the heavy quark masses, are determined
simultaneously with the PDFs and interplay emerging between various fit
ingredients is discussed.
