I think it's been out even longer than that.
It fixes a rather large number of issues, and I haven't really noticed anything that it broke. I remember seeing something bad that it did, but it was something that doesn't affect us, and I can't even remember what it was at this point.
And if it was causing problems for people, we'd probably be seeing a lot more posts about it. The silence is a good sign. It might be Autodesk's most-successful service pack yet, as far as "doing no harm" goes.
