I'm sure you all know about this already, but just in case:  Scott Cate, a microsoft MVP who has been bestowing his knowledge of the .NET Framework to the great state of Arizona since the year 2000 (and probably prior),   runs a notification service called KBAlertz that will alert you via email whenever Microsoft adds/edits a knowledge base article related to hundreds of Microsoft products and technologies.     I have found his service to be invaluable in keeping up with changes and bug fixes.  You'll also get summary emails of recent updates in case you don't have time to read each individual one. All .Net professionals should be subscribed to this service.  It only takes a second.  Go.  Do it now.
