 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 1.427
+Corrected a problem with rendering of larger small caps, caused by not making some definitions global in the relevant fd files.

 Changes in version 1.426
 1. Corrected a serious error in the code for parsing newpx-subs.tex for subscript corrections.
 2. Added subscriptcorrectionfile, a new option to newpxmath, allows you to specify a different subscript correction file than the usual newpx-subs.tex.

 \item \verb|\coloneq| and \verb|\eqcolon| now point to the correct glyphs;
 \item The problem with the {\tt ogonek} accent  and tabular environments (bad definition of \verb|\k|) is fixed;
 \item The default encoding for \textsf{newpxtext} is now T$1$, but support is offered also for OT$1$ and LY$1$. As some add-on packages are available only in T$1$, that seems the best current choice.
-\item The font collection used for rendering text is based on TeXGyrePagella with a number of additions, denoted by TeXGyrePagellaX. The superior figures in this addition are set by default to render footnote markers. (It is also possible customize footnote markers by redefining \verb|\thefootnote| after loading {\tt newpxtext.sty}.) Small caps are available in all weights and styles, and are offered in two sizes. The default small caps supplied by TeXGyrePagella are really \textsc{Petite Caps}, having xheights approximately the same x-heights (sometimes smaller) as lowercase letters. Option \texttt{largesc} increases the size of small caps by about 8\%, approximating the size of Adobe Palatino Small Caps. IMO, this is a better match in terms of weight and size. For a side by side comparison: {\pcf Petite Caps}, \textsc{Small Caps}.

 \item {\tt uprightGreek} and {\tt slantedGreek} determine the form of Greek alphabet loaded---the default is {\tt uprightGreek}, which loads upright uppercase and slanted lowercase Greek symbols, as is customary in Anglo-American mathematical typesetting. With the option {\tt slantedGreek}, which you might want to use if you cared about ISO standards, all Greek symbols are slanted. No matter which is set, \verb|\Gammaup| (or \verb|\upGamma|) gives you upright \verb|\Gamma|, etc, and \verb|\Deltait|, \verb|zetait| give you italic (i.e., slanted) versions of those letters, and \verb|\mathnormal{\Omega}| etc will always produce the slanted version of uppercase Greek letters. (The macro \verb|\mathnormal| means essentially ``use the version of the symbol in {\tt letters}''---i.e., the math italic form. This did not always work as expected in versions prior to 1.27.)
 \item The \textsf{newpxmath} package contains three different Blackboard Bold alphabets, where original \textsf{pxfonts} contained one. The default, triggered by \verb|\mathbb{}|, takes its glyphs from the font which replaces {\tt msbm} and has the same overall appearance of a hollowed-out text font, which I find neither bold nor blackboard-like. The second option, taken from \textsf{pxfonts}, is triggered by \verb|\varmathbb{}|, is more geometric and, in my opinion, preferable but not optimal. The option {\tt varbb} makes \verb|\mathbb{}| synonymous with \verb|\varmathbb{}|. The third option is the double-struck glyphs from the STIX collection. See the expanded discussion below.
 \item {\tt nosymbolsc} causes the package to not load the {\tt symbolsC} fonts, saving  a math family. (This font contains mostly exotic symbols, along with some very useful, commonly used symbols like \verb|\coloneq| $\coloneq$, \verb|\eqcolon| $\eqcolon$, \verb|\notin| $\notin$, \verb|\notni| $\notni$, \verb|\neq| $\neq$, \verb|\nsubset| $\nsubset$ and \verb|\nsupset| $\nsupset$, but these have been moved (virtually) to {\tt lettersA} so they may continue to be used even if you use the option {\tt nosymbolsc}.)
-\item {\tt amssymbols} (the default) and {\tt noamssymbols} determine whether the {\tt pxfonts} versions of the \textsc{ams} symbols ({\tt msam}, {\tt msbm}) are loaded---if so, they override previous settings in {\tt amsmath}. If you use the option {\tt noamssymbols}, then \verb|\mathbb{}| is set to mean the same as \verb|\varmathbb{}|. (One advantage of {\tt noamssymbols} is that you save one of your precious math families for other purposes, such as setting a couple of external math alphabets by means of the \textsf{mathalpha} package.)

-(New as of version $1.426$:) If you wish to make changes to {\tt newpx-subs.tex}, it is possible though not wise to copy the file to your home TeX folder where it will be found by TeX before the one in the distribution. The problem is that it is easy to forget where the file is located when you want to make changes. For the moment, my advice is to place the file contents with your changes inside a {\tt filecontents} environment at the top of your source file, as shown below. The effect will be to write that file in the same folder as your source, overwriting any existing copy. Version $1.426$ also offers you a new option {\tt subscriptcorrectionfile} that lets you specify a file name other than the default {\tt newpx-subs.tex} that can be used to specify a subscript correction file for some special use.
