Today Microsoft has released a new cumulative update for SQL Server 2008 SP3.
- KB article: KB #2771833
- There are 9 fixes listed at the time of writing
- The build number is 10.00.5828.00
- Relevant for @@VERSION between 10.00.5500 and 10.00.5827
It seems clear that Service Pack 2 servicing has been discontinued. So there is even less reason to hold onto those old builds, and every reason to upgrade to Service Pack 3.
As usual, I'll post my standard disclaimer here: these updates are NOT for SQL Server 2008 R2 (where @@VERSION will report 10.50.xxxx).
