The minor releases of different overall variants like V3 and V4 now.. I don't if the minor variants of releases offer more protection? In an environment such as mine it really is not possible to manage this, and have time to do much of anything else without some kind of automated process *2,000 clients*. I have found myself regretting imaging with a client version in the past because within a month or two a new one is out sometimes sooner.. is it safe to adopt a standard, and stick with it in regards of a version that works.. Right now 220.127.116.11 or 3.0.684 are the only ones that I would consider aside from 2.7 but it is dated on the client protection by now I would assume. 4.0.314 looks very good until it mated with my Novell clients, and I got screamed at by a head guy at a division where people test asking me why we got the skeleton looking robot thing that crashed every 20-30 minutes with BSoDs..
