8.42 definately integrates with xenforo better than we do in vb 3 or 4. There have been tons of changes in the 8 series as a whole. I would suggest you check out all the various announcements.
I just got done with 3 releases all in a row this year and just released various versions. After the holidays is when I will look at what specific things I will get into and work on the next beta version. You can as always place any suggestions in the suggestions forum.
