You might feel that this announcement is a little late, but we downloaded rollup 10 right after it was announced and found that it had some problems. It was subsequently re-released, but that didn’t fix the problems that the first release of rollup 10 caused. So now I’m going to wait a week or two before I announce rollups to make sure that Microsoft has an opportunity to revise them before I recommend that you download. At this point rollup 11 has been available for a month, so it should be safe to install. We will be installing it this weekend, and I will make note of any issues that we run into
