In incremental service update to Update 1 has been made available. A “servicing” update is actually a bunch of hotfixes packaged together over a full Update. In the old days it would be called a Hotfix pack to a Service Pack. Interesting how nomenclature changes over time.
As for its contents, it fixes the nagging issue with Update 1 in that Visual Studio would unexpectedly crash while debugging. See this page for more details. Please keep them coming. This particular issue was painful to live with, even if for just a few weeks.
