We present the updated global fits of the Standard Model and beyond to the electroweak precision data, taking into account the Higgs mass measurements at the LHC and recent progress in theoretical calculations. We use the up-to-date theoretical expressions for the partial widths of the Z boson which include the full two-loop fermionic electroweak contributions. From the global fits, we derive model-independent constraints on new physics by introducing the oblique parameters, the epsilon ones, the modified Zbb couplings, and the dimension-six effective Lagrangian.
