  The observation of coherent elastic neutrino nucleus scattering has opened
the window to many physics opportunities. This process has been measured by the
COHERENT Collaboration using two different targets, first CsI and then argon.
Recently, the COHERENT Collaboration has updated the CsI data analysis with a
higher statistics and an improved understanding of systematics. Here we perform
a detailed statistical analysis of the full CsI data and combine it with the
previous argon result. We discuss a vast array of implications, from tests of
the Standard Model to new physics probes. In our analyses we take into account
experimental uncertainties associated to the efficiency as well as the timing
distribution of neutrino fluxes, making our results rather robust. In
particular, we update previous measurements of the weak mixing angle and the
neutron root mean square charge radius for CsI and argon. We also update the
constraints on new physics scenarios including neutrino nonstandard
interactions and the most general case of neutrino generalized interactions, as
well as the possibility of light mediators. Finally, constraints on neutrino
electromagnetic properties are also examined, including the conversion to
sterile neutrino states. In many cases, the inclusion of the recent CsI data
leads to a dramatic improvement of bounds.
