The notes talk about new ODBC drivers. If I read them correctly they are NOT included in the CU right? If we want to use them we need to download and install them?

@Ville can you be more specific? What exactly wasn't working?

@Chris yes, I believe those are completely separate. There's usually an update for CUs meant just for connectivity components and drivers (usually it has SNAC in the name) but I don't know if that's there anywhere (it is only relevant when there are changes to client libraries) or if it would include ODBC stuff anyway aside from native client explicitly.

The blog post talks about it more and has download links:

I guess it's late to answer already, but I was getting some sort of exception right after clicking to start management studio after the update. After reboot it was fine.

Well I can also say that if management studio has been running longer (I don't know what is the trigger) it will always crash when I'm shutting it down. But this has been a problem since RTM and I've sent the report every time it happens.

Aaron, I was installing this CU2 hotfix on some of my servers and was wondering why is this patch reported as QFE type:

 KBArticle:                     KB2790947


 PatchType:                     QFE

Does it matter when next package will be applied?
