The Circular Electron Positron Collider (CEPC) is a facility with a wide range of physical scope. It can serve as the Higgs, W, and Zbosons factories, allowing the study of Higgs, electroweak (EW), QCD, flavor physics as well as Beyond Stand Model (BSM) physics. Numerous studies for Higgs measurement were revised and documented after the completion of the conceptual design report (CDR) [1] and the Higgs white paper [2]. For the new nominal operation scenario [3], CEPC can deliver a few factors enhanced events yields of Higgs, Wand Zbosons, it can also provide a run at a 360 GeV center-of-mass energy, enabling top coupling measurement and good improvements in Higgs precision measurement. With upgradeable running plans, physics potential is studied at CEPC on a variety of topics, such as benchmark processes of Stand Model particles and BSM searches. These highlights from recent updates will be discussed.
