A unique feature of VEPP 4M is the high precision beam energy calibration by resonant polarization technique which allows conducting of interesting experiments despite the low luminosity of the collider. Recently we have started new luminosity acquisition run above 2 GeV. The hadron cross section was measured from 2.3 GeV to 3.5 GeV has been done. The luminosity run for gamma-gamma physics has been started. The luminosity at Y(1S) meson has been obtained. For the beam energy calibration the laser polarimeter is used. The paper discusses recent results from VEPP 4M collider.
