+ \subsection{Removed spurious warning for generic graphics rules}
+ 
+ A previous release mistakenly caused a warning to appear when loading a graphics
+ file with an unknown extension through a generic graphics rule.  The warning
+ would incorrectly say that the file was not found, whereas the file would be
+ included correctly.  The warning now doesn't show up in that case.

 +\subsection{Fixed loading \texttt{gzip}ped PostScript graphics files}
 +
 +A previous release mistakenly changed the file searching mechanism and
 +compressed graphics files would raise an error when being loaded with
 +\cs{includegraphics}.  This has been fixed and now \texttt{gzip}ped graphics
 +load correctly.

+ 	for security reasons.  dvips directly supports zip

+ 	be executed via \special{`command..}

+
