R has no built-in support for non-Sweave vignettes, and there is no 
mention of pandoc in the R 3.1.3 sources except for the manual:

'Complete checking of a package which contains a file @file{README.md}
needs @command{pandoc} installed: see
@uref{http://johnmacfarlane.net/@/pandoc/@/installing.html}.'

which is true (but is not done with R 3.1.3).

I suspect you are confusing an R update with an update of whatever 
packages you use to process your vignettes: package rmarkdown has a 
pandoc version requirement of

SystemRequirements: pandoc (>= 1.12.3) -
