I sometimes still use SGP 3 (32bit) 126.96.36.1990 for imaging. I noticed that the last update for 660 was in March 2021. I assume V3 is at the end of life stage and is no longer being supported. There is only one feature that I would like to see implemented, if possible, and that is the auto-focus have the option to use HDF-ASTAP instead of the Half Flux Radius.
I plan on renewing my subscription to V4 mid year, however, when I do image minimally, I would enjoy having the ability to use ASTAP for auto-focus with V3.
