  NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a fixed target
experiment located at the CERN SPS. Its strong interactions program is devoted
to study properties of the phase diagram of strongly interacting matter. For
this goal the two-dimensional scan is performed by measurements of hadron
production properties as a function of collision energy (13A - 158A GeV/$c$)
and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb). This contribution
presents new results on the onset of deconfinement - the transition between the
state of hadronic matter and the quark-gluon plasma. Also, new results on
fluctuations and correlations devoted to the search for the critical point of
strongly interacting matter will be presented. Obtained results are compared
with the available data from other experiments and from various theoretical
models.
