The second Gaia data release (DR2) is scheduled for April 2018. While Gaia DR1 had increased the number of stars with parallaxes by a factor 20 with respect to the Hipparcos catalogue, Gaia DR2 will bring another factor 500 increase, with parallaxes (and proper motions) for more than a billion stars. In addition, Gaia DR2 will deliver improved accuracy and precision for the astrometric and photometric data, G, GBP, GRP magnitudes, radial velocities, identification and characterisation of variable stars and asteroids as well as stellar parameters for stars down to G=17 mag. On behalf of the teams of the Gaia-DPAC consortium, these proceedings give a foretaste of Gaia DR2, 6 months before the release.

5 pages, 3 figures, SF2A Conference 2017 V2: Typo correction. There will be 500 times more stars with a parallax (and proper motions) in DR2 wrt DR1 (not 50)
