Comment on March 2016 CU for SharePoint 2010 product family is available for download by Stefan Goßner

Hi Anders,
that is expected. If you check my blog post you will notice that the last time a SharePoint Foundation CU was released before May 2016 was in Feb 2016.
As the build numbers you refer to only Report the patch level of the SharePoint Foundation layer and not the patch Level of other components included in the SharePoint Server Layer you will see the Feb CU build number here.
Don’t trust this number – it often gives you a wrong indication about installed fixes.
Cheers,
Stefan
