    The CMD-3 detector has been taking data since December 2010 at the VEPP-2000 electron–positron collider. The collected data sample corresponds to about 60 inverse picobarn of integrated luminosity in the c.m. energy range from 0.32 GeV to 2.0 GeV. Preliminary results of the analysis of various hadronic cross-sections, in particular, e+eπ+π, π+ππ0, KLKS, K+K, ηγ, 3(π+π), 2(π+ππ0), K+Kπ+π, K+Kη, K+Kπ0, ηπ+π, ωπ+π and ωπ0e+e are presented. The processes with multi-hadron final states have several intermediate states which have to be taken into account to correctly describe the angular and invariant mass distributions, as well as cross-section energy dependence.
