After the upgrade of the positron injection facility the electron-positron collider VEPP-2000 started to operate at the end of last year and delivers an excellent luminosity, which is higher than the previous in 2-3 times. The detector CMD-3 has gained a new statistic, which corresponds to integrated luminosity of about 30 pb$^{-1}$. Many processes in the energy region from 1 to 2 GeV go through the production of multihadron events with kaons in the final state. The paper presents preliminary results of measurements of the cross sections for some processes.These new results are badly required to improve the unceraincy of calculation of the hadronic contribution to (g-2)/2 of muon particularly in the light of new experiment in FNAL.
