dsws DLLs for SP7

I just upgraded a sandbox server from FP5.6 to SP7. However, I noticed that the web services DLLs in BusinessObjects Enterprise 12.0\web services\en\dsws_consumer\data\dswsDotNet2Api all have a file date of 11/29/2011, and a version of 12.5.2000.1190.

Does this mean that the web services DLLs have not been touched since SP5, or was my upgrade incomplete?
