Too soon to say much, but the new multi-PV mode seems to work OK in the Preview
version. Also the length of analysis has been increased. The beta version
produces analysis displays about 10 ply long, which decreased to 2-3 ply at
longer times (several hours). In contrast the length of displayed analysis in
the Preview version starts at about 10-12 ply, and I'm seeing 14 ply after
letting it run for an hour in infinite mode. That's what was promised, that the
length of analysis would increase with longer run times. I haven't had time to
evaluate how good the analysis is, but so far haven't noticed any glaring
errors. So far, so good...
