  We revisit the global QCD analysis of parton-to-kaon fragmentation functions
at next-to-leading order accuracy using the latest experimental information on
single-inclusive kaon production in electron-positron annihilation,
lepton-nucleon deep-inelastic scattering, and proton-proton collisions. An
excellent description of all data sets is achieved, and the remaining
uncertainties in parton-to-kaon fragmentation functions are estimated and
discussed based on the Hessian method. Extensive comparisons to the results
from our previous global analysis are made.
