posted another bi-weekly version of the FreeBSD 5.2 open issues list, slightly restructured. At this time, there are four "show stopper defects" listed: panics when building ata-raid arrays, ATAng crashdump causes disk corruption, pipe/VM corruption on Alpha, and lingering PSE instability. There are only 5 issues left of on the "required features" list: KSE support for sparc64, KSE support for alpha, Fine-grained network stack locking without Giant, MAC framework devfs path fixes, and ACL_MASK override of umask support in UFS.
Well, I don't know - I'm a newbie too, and tried both 4.8 and 5.1 - They are both fine, I am currently using 5.1. The latter has slightly older packages, but you will use the ports system anyhow, so that's not much of a difference (I think 5.1 comes with KDE 3.1.2, 4.9 with 3.1.4).

One advice: read the Handbook before you go installing it. It is very well written, and yes, its newbie friendly, and most importantly: up to date. So, when there are differences between the 4.x and 5.x branches, they are explained in the handbook.
All I can say of 5.1 is that it is rock stable, I didn't have any problems using it (one home desktop, and one server). But its up to you - if I hadn't installed 5.1 a few weeks ago, I would use a dice now to decide
