Me too, with:

 This is XeTeX, Version 3.1415926-2.2-0.9997.4 (TeX Live 2010)
and
 This is XeTeX, Version 3.1415926-2.4-0.9998 (TeX Live 2012)


With 2010 the font versions, as encoded in the font itself, are
  FontForge 2.0 : Free Serif : 4-1-2009    Version $Revision: 1.358 $
  FontForge 2.0 : Free Serif Italic : 4-1-2009   Version $Revision: 1.175 $

With 2012 the font versions, as encoded in the font itself, are 
  GNU: FreeSerif Normal: 2012	Version 0412.2263
  GNU: FreeSerif Italic: 2012   Version 0412.2268


With the 2012 font, I get a lot of warnings about unsupported features;
viz.

Sorry, I don't have TeX Live 2011 installed, nor 2013.
Though I'd suspect the font itself for such a result.
