  The SOUL systems at the Large Bincoular Telescope can be seen such as
precursor for the ELT SCAO systems, combining together key technologies such as
EMCCD, Pyramid WFS and adaptive telescopes. After the first light of the first
upgraded system on September 2018, going through COVID and technical stops, we
now have all the 4 systems working on-sky. Here, we report about some key
control improvements and the system performance characterized during the
commissioning. The upgrade allows us to correct more modes (500) in the bright
end and increases the sky coverage providing SR(K)>20% with reference stars
G$_{RP}$<17, opening to extragalcatic targets with NGS systems. Finally, we
review the first astrophysical results, looking forward to the next generation
instruments (SHARK-NIR, SHARK-Vis and iLocater), to be fed by the SOUL AO
correction.
