The LaTeX Team  submitted an update to the

                iftex

package.

Version number: 1.0c
License type: lppl1.3c

Summary description: Am I running under pdfTeX, XeTeX or LuaTeX?

Announcement text:
----------------------------------------------------------------------

Update to iftex with no change to the user interface but internal tests
now treat \relax like undefined when testing for the existence of
engine-specific commands.

So for example \ifxetex is set to false if \XeTeXrevision is undefined
or if it is defined to be \relax.

----------------------------------------------------------------------

This package is located at 
   http://mirror.ctan.org/macros/latex/contrib/iftex

More information is at

   Thanks for the upload.
