Cumulative updates have not always been popular with DBA’s as may of you prefer to wait for service packs like the upcoming sp3 for SQL Server 2005, to reduce testing and downtime. However if you are hit with a particular problem then hotfixes and cumulative updates are the the solution.
I am surprised there is already one of these in an attendant Knowledge Base article (KB) for SQL Server 2008 here, but do check this if you are evaluating or developing in SQL Server 2008 already.
If you want to understand how service packs, hot fixes and cumulative updates fit together then check this post form the SQL Server Global Release Services Team.
Is there one central point or method of receiving notification that a hotfix or cumulative update has been releaseed for SQL Server? Things like an RSS feed or some such resource?
