This article summarizes the status of the global fit of the Cabibbo-Kobayashi-Maskawa (CKM) parameters within the Standard Model performed by the CKMfitter group. Special attention is paid to the inputs for the CKM angles $\ensuremath{\alpha}$ and $\ensuremath{\gamma}$ and the status of ${B}_{s}\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\mu}$ and ${B}_{d}\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\mu}$ decays. We illustrate the current situation for other unitarity triangles. We also discuss the constraints on generic $\mathrm{\ensuremath{\Delta}}F=2$ new physics. All results have been obtained with the CKMfitter analysis package, featuring the frequentist statistical approach and using Rfit to handle theoretical uncertainties.
