DR4

'pon looking at ESA's Gaia DR3 (pdf), I am now anticipating DR4.

DR3 covered observations 25 July 2014 to 28 May 2017. The Early Data Release in 2020 had actually released most of the raw material, with the full DR3 being a cleanup. (Hence how that Brown Dwarf paper was able to use DR3 parallax.) With over a billion point-sources to study, said KP does take some time.

The Lazorenko-Sahlmann 2018 study of the Luhman 16 pair - also running up to 2017 - had used DR2. It used this as background only. For the pair itself, the study blew DR2 off. So now we have DR3, but I don't know to what extent Lazorenko and/or Sahlmann will care.

Even looking at the data is difficult on account it's all a lot of gigabytes, 9 TiB in fact. ("Ti" is the classic Microsoft terabyte, 1024 GiB on down.) Although if you are a nerd who hasn't filled up your hard drive with... whatever; it may be worth your while.

However the Gaia mission is not over. Upcoming is DR4. That release is on schedule for early 2026 (pdf); the raw data are already here.
