 This package, based initially on pxfonts, provides many fixes and enhancements to that package, splitting it in two parts---newpxtext and newpxmath---which may be run independently of one another. It provides scaling, improved metrics, and other options. For proper operation, the packages require that the packages newtxmath, pxfonts and TeXGyrePagella be installed and their map files enabled. The text package now relies on an extension of the TeXGyrePagella Type1 fonts that is provided with this package. The accompanying MANIFEST-newpx.txt provides details of the extension as requested by GUST-FONT-LICENSE.txt

+Changes in version 1.534
+1. Made changes to a number of fd files to rework some incorrect \providefile entries. (Thanks Martin Münch.)
+2. Added four declarations to newpxtext.sty of the form
+	\DeclareFontFamilySubstitution{\encodingdefault}{zplLF}{zpllf}
+so that the old names for font families would work as well as the new
+lowercase forms. 
 Changes in version 1.533
 1. Introduced a sequence of curly braces to replace standard braces if you specify 
 the option curlybraces to newtxmath.
