Do you mean the FAQs available at http://www.games-workshop.com/gws/content/article.jsp?categoryId=500004&pIndex=1&aId=3000006&multiPageMode=true&start=2 ? It looks like the general rules were updated to 1.5 and LM to 1.4 since I last checked.
Yeah the latest LM FAQ has been up for a month and a half, and the last update really added very little anyway. Just a point about skrox not being able to be stomped since they are a mixed unit, and how cold blooded works against things that make you roll 3d6 and pick the highest 2.
The biggest thing is the change to the power scroll rules. It now halves casting value instead of causing irrisistable on doubles. It makes the great leveller actually castable (but since you never actually want to cast the great leveller as you can only cast it while you are winning...).
