Hello:
I just downloaded and installed December 2012 CU for SharePoint Foundation 2010 from the following link:
http://support.microsoft.com/kb/2596957
The KB indicates that the build for this update should be 14.0.6131.5001. However, after successful installation of the CU - my farm displays 14.0.6131.5000. Please see screen shots. Does this indicate an issue? I'm not sure why the version would ready 5000 and not 5001.
Thank you,
Rumi
