RU12 (CRM 2011) and Windows Server 2008 R2 SP1

Hi,

I see that rollup 12 (RU12) is now available for CRM 2011 on-premise.

Can anybody confirm if RU12 supports Windows Server 2008 R2 SP1?

Or is this already supported in a previous RU but not yet reflected in the CRM 2011 compatibility list article.

Thanks,

Peter
