This package contains slight extensions of the GUST TeXGyrePagella fonts, adding a full set of superior figures and letters. The newly generated type1 fonts are: zplr.pfb zplri.pfb zplb.pfb zplbi.pfb from which all the newpxtext font metrics were derived. In addition, 6 glyphs from TeXGyrePagellaMath-Regular.otf were used to make two type1 fonts: zplx-regular.pfb zplx-bold.pfb and these were used as ingredients in newpxmath. Starting with version 1.24, the package also supplies the extended fonts in otf format: TeXGyrePagellaX-Regular.otf TeXGyrePagellaX-Bold.otf TeXGyrePagellaX-Italic.otf TeXGyrePagellaX-BoldItalic.otf
