	VEPP-2000 is the only electron-positron collider operating with round beams that allow to enhance beam-beam limit. VEPP-2000 with SND and CMD-3 detectors carried out two successful data-taking runs after new BINP injection complex was commissioned. The 2016/2017 run was dedicated to high energy range (640-1000 MeV per beam) while the 2017/2018 run was focused at 275-600 MeV/beam energies. With sufficient positron production rate and upgraded full-energy booster the collider luminosity was limited by beam-beam effects, namely flip-flop effect. Thorough machine tuning together with new ideas introduced to suppress flip-flop allowed to establish new world record for beam-beam parameter and bunch-by-bunch luminosity values at specific beam energies. The achieved luminosity increased 2-5 times in a whole energy range in comparison to phase-1 operation (2010-2013).

	VEPP-5 Injection Complex (IC) is designed to supply BINP RAS colliders with high energy electron and positron beams. Recently constructed K-500 beam transfer line connects IC to both VEPP-4M and VEPP-2000 colliders. IC two collider operation was successfully started in 2016. Nowadays, research on improvement of IC performance is carried out, in particular 10.94 MHz RF cavity was installed instead of 700 MHz one and a new 10 A electron gun installation is expected to be in winter 2018-2019. Moreover, streak-camera based longitudinal beam profile measurements in IC damping ring were carried out and BPM system in the damping ring was upgraded. Operation experience of IC and results of longitudinal beam profile measurements are reported.

	The paper describes bunch dimension measurements in VEPP-2000 collider at energy 350 MeV. The three bunch dimensions (transverse sizes along with bunch length) was measured against bunch current to detect the energy spread growth. Emmitance growth due to multiple intrabeam scattering was observed at bunch current below turbulence bunch lengthening threshold. The thresholds of these proceses was used to estimate values of longitudinal impedance. Obtained values in a good agreement with predictions.

	VEPP-2000 electron-positron collider for multiple injection and stacking uses traditional scheme with pre-kicker, kicker and pulsed thin septum magnet. It was found earlier that despite the shielding septum stray field disturbs the circulating beam and sweep it's betatron tune long after the magnet pulse. This work presents the beam-based measurements of mechanical aperture at the interaction region and discusses stray field mapping technique.

	The longitudinal beam profile measurement system based on optical dissector was upgraded at booster synchrotron BEP during VEPP-2000 collider complex 2017/2018 data taking run. New RF-cavity of 13-th harmonic was installed during the booster upgrade in 2013-2015 to increase top energy to 1 GeV. The complex work on synchrotron radiation output modernization was performed, and measurement system was commissioned. The system was tested and calibrated, the resolution was studied. The bunch length dependence was measured for different RF cavity voltages while beam current changes and compared with the potential well distortion model. Good agreement with theory proved system operability. In addition the results of bunch length current dependence obtained by dissector at VEPP-2000 collider were compared with streak-camera measurements being in a good agreement. The synchrotron tune dependence on RF-cavity voltage was measured both at BEP and VEPP.
