  The Coherent Neutrino-Nucleus Interaction Experiment (CONNIE) uses fully
depleted high-resistivity CCDs (charge coupled devices) with the aim of
detecting the coherent elastic scattering of reactor antineutrinos off silicon
nuclei and probing physics beyond the Standard Model. The analysis of the
2016--2018 data allowed us to set an upper limit at 95% confidence level on the
coherent scattering rate, which was used to place stringent constraints on
simplified extensions of the Standard Model with light scalar and vector
mediators. In 2019, the experiment operated with an improved readout and a
lower energy threshold of 50 eV. We present the performance of the CONNIE
experiment, new results of the analysis of 2019 data, and the recent update of
the detector with skipper CCDs.
