Abstract
The CMD-3 detector is taking data at the VEPP-2000 $e^+e^-$
collider (Budker INP, Novosibirsk, Russia). The main goal of experiments with CMD-3
is the measurement of the cross-sections and dynamics of the exclusive
modes of $e^+e^- \to hadrons$ reactions. In particular, these results provide
important input for calculation of the hadronic contribution to the muon anomalous magnetic moment.
First round of data taking with the CMD-3 detector was performed in 2011-2013 with about 60
1/pb integrated luminosity in the energy range from 0.32 to 2.0 GeV
in center-of-mass. Amount of collected data exceeds all previous experiments.

Here we present the survey of results of data taken in 2011-2013,
including precise measurement of $e^+e^-\to \pi^+\pi^-$ reaction, as well as other
hadron final states with up to 6 pions or states include 2 kaons.

At the end of 2016 the VEPP-2000 collider resumed operations after upgrade
of the injection system, and performance approaching to the project
luminosity of $10^{32}\ cm^{-2}s^{-1}$ at 2 GeV has been demonstrated. First
preliminary results of new 2017 run are also presented.
