More than five years after the first gravitational-wave detection of a binary black-hole merger, we consider such detections routine and we are focusing on extracting population astrophysical information from a rapidly growing number of black-hole detections while tightening constraints on the nature of neutron stars combining knowledge from both gravitational waves and electromagnetic observations. In parallel, gravitational-wave observations continue to surprise us with discoveries of mergers with unexpected properties, while this year we have completed the full set of expected merger types, including black holes with neutron stars. In this talk I will summarize where our understanding stands at present, focus on some exceptional sources that puzzle us, and discuss what we anticipate for the future.
