  According to recent experimental data and theoretical developments we discuss
three distinct topics related to strangeness enhancement in nuclear reactions.
We investigate the compatibility of multi-strange particle ratios measured in a
restricted phase space with thermal model parameters extracted recently in 4pi.
We study the canonical suppression as a possible reason for the observed
strangeness enhancement and argue that a connection between QGP formation and
the undersaturation of strangeness is not excluded.
