In order to further characterize this transition, and in the pursuit of indications for the expected critical point of strongly interacting matter, the NA49 collaboration has conducted analyses of the event-by-event fluctuations of various hadronic observables. A selection of these results will be presented and discussed in the light of theoretical predictions. Among these are new results on hadron ratio fluctuations, in particular K/p fluctuations and their potential connection to the correlation between strangeness and baryon number, thus revealing the basic degrees of freedom produced in heavy-ion collisions.
