Microsoft has released SQL Server 2008 Service Pack 3 Cumulative Update #16

• Build # 10.00.5852
• KB Article: KB #2936421
• 2 public fixes
• Relevant for builds 10.00.5500 -> 10.00.5851
• NOT for SQL Server 2008 R2 (10.50.xxxx)

The small number of fixes (and zero fixes for the engine) should be very telling: support for this, almost certainly the last service pack for SQL Server 2008, ends in July. If you're still on 2008 (and I know some of you are still on 2005 and even 2000, and this isn't motivation enough), it might be time to start considering moving on – if for nothing else, but to benefit from a healthy dose of fixes.
