-Updated coordinates and distances with data from Gaia EDR3, Kirkpatrick et al. (2021) and other sources
-Added six new brown dwarfs (2MASS 0521+1025, 2MASS 1928+2356, CWISE 1055+5443, WISE 0049+2151, WISE 2000+3629 and WISE 2354+0240)
-Updated parameters for α Centauri, Luhman 16, Procyon, Gliese 229, Gliese 661 and Gliese 105 systems
-Fixed orbits for Gliese 65, ξ Ursae Majoris A and a few spectroscopic binaries
-Minor fixes and updates (e.g. add missing parameters)
