Abstract
The first round of data taking with the CMD-3 and SND detectors at the
VEPP-2000 e+e collider (BINP, Novosibirsk, Russia) was performed in 2011-2013.
The main goal of experiments at VEPP-2000 is measurements of cross sections
and studies of dynamics of exclusive modes for $e^+e^-\to hadrons$.
In particular, these results provide important input for calculations
of the hadronic contribution to the muon anomalous magnetic moment.

Here we present the survey of analysis of data taken in 2011-2013. About
60 pb$^{-1}$ per detector were taken in the c.m. energy range from 0.32 to 2.0
GeV. The beam energy was continuously measured concurrently with data taking
using Compton backscattering. In 2016 VEPP-2000 resumed operations after
upgrade with a design luminosity of $10^{32}$ cm$^{−2}$s$^{−1}$ at 2 GeV.
