[en] Observations for the HOSTS (Hunt for Observable Signatures of Terrestrial Systems) survey for warm dust around nearby stars (exozodiacal dust, i.e., dust in and near their habitable zones, HZs) have been completed in the first half of 2018 (during observing semester 2018A). The goal of HOSTS was to constrain the occurrence rate and typical level of exozodiacal dust around a sample of nearby starsin order to assess the risk imposed by this dust to future space missions attempting to directly image habitable exoplanets. We here report on the immediate conclusions of the survey relevant to this goal.Detailed descriptions of the HOSTS observing strategy, data reduction, and analysis together with detailed statistical results were provided by Ertel et al. (2018a). Here, we provide only a brief summary of these points and updates where necessary. In particular, we provide the final null measurements and derived HZ dust levels (zodi levels) for all observed stars and final statistics derived from those measurements.
