  We present new sets of next-to-leading order fragmentation functions for the
production of K0short and Lambda particles from the gluon and from each of the
quarks, obtained by fitting to all relevant data sets from e+e- annihilation.
The individual light quark flavour fragmentation functions are constrained
phenomenologically for the first time by including in the data the light quark
tagging probabilities measured by the OPAL Collaboration.
