Information Steward 4.2 SP2 Windows Support

Hi, I'm looking for clarification on the SAP Information Steward 4.2 Product Availability Matrix. On Page 5, there is a chart which specifies which IS service pack is compatible with which Windows operating system.

My question is for Windows Server 2008 R2 x64, on column 4. Is this saying that only IS RTM SP1 is supported for Windows Server 2008 R2 and not IS RTM SP2? If so, when can we expect IS RTM SP2 to be approved for Windows Server 2008 R2?

Thanks,

DC
