Multiplicity and Net-Charge Fluctuations in Ion $\mathbf{+}$ Ion Collisions at the SPS Energies

This contribution presents new results of NA61/SHINE on multiplicity and net-charge fluctuations measured with higher-order moments. It includes both rapidity dependence in p $\mathbf{+}$ p interactions as well as system size and energy dependence with Be $\mathbf{+}$ Be and Ar $\mathbf{+}$ Sc interactions. Obtained results are compared with the available data from other experiments and from models.
