CUOREhas been taking data since summer 2017, and as of summer 2018 collected a total of 86.3 kg$\cdot$yr of TeO$_2$ exposure. Based on this exposure, we were able to set a limit on the $0\nu\beta\beta$ half-life of $^{130}$Te of $T^{0\nu}_{1/2}g1.5\times10^{25}$ yr at 90% C.L. At this conference, we showed the decomposition of the CUOREbackground and were able to extract a $^{130}$Te $2\nu\beta\beta$ half-life of $T_{1/2}^{2\nu}=[7.9\pm0.1 \mathrm{(stat.)}\pm0.2 \mathrm{(syst.)}]\times10^{20}$ yr. This is the most precise measurement of this half-life and is consistent with previous measurements.
