  Since 2004, the principal high-energy physics experiment carried out at the VEPP-4M electron-positron collider is precise measurement of the tau-lepton mass. Moreover, a series of experiments to improve measurement accuracy of the J/psi, psi(2s) and psi(3770) mesons has been performed. During all the high-energy physics experiments, absolute calibrations of beam energy by the resonant depolarization method and routine energy monitoring using the Compton back-scattering technique were realized. Monitoring of beam energy spread, which is also important, was implemented using several techniques. To provide the VEPP-4M high performance, some investigation and further development of the machine have been done, the most important results are described.
