Upgrade path from version 3.2 to 4+

I have been using SG for some yrs now, all the way back to its early development.
Currently I use the highest level upgrade from previous license, I believe ver 3.2.

Generally I am very happy w the product. It seems that the one thing that causes me the most trouble regularly is autofocus. Often going thru a number of iterations and failing.

My question is has the auto focus seen further development since 3.2?
Has their been changes and improvements to the overall interface?


Major changes for SGP4 are 64bit and interfacing with Switches. Autofocus was revamped in 3.2 and has been generally much more successful. You can always start a trial of SGP4 and check things out for yourself as well.
