  At the time of this meeting, the latest Gaia data release is EDR3, published
on 3 December 2020, but the next one, DR3, will appear soon, on 13 June 2022.
This contribution describes, on the one hand, Gaia EDR3 results on massive
stars and young stellar clusters, placing special emphasis on how a correct
treatment of the astrometric and photometric calibration yields results that
are simultaneously precise and accurate. On the other hand, it gives a brief
description of the exciting results we can expect from Gaia DR3.
