This package, initially based on txfonts, provides many fixes and enhancements to the txfonts package, splitting it into two separate packages---newtxtext and newtxmath, which may be run independently of one another. It provides scaling, improved metrics, and other options. In particular, newtxmath offers a libertine option which substitutes Linux Libertine (provided with TeXLive and MikTeX) italic and Greek letters for the default Times letters, providing a good match for the Libertine text font, which is heavier than Computer Modern but lighter than Times, and in my experience, looks very sharp and clear on the screen.

\section{Introduction}
This package is meant to be a replacement for Young Ryu's {\tt txfonts}. It is a complete text ({\tt newtxtext}) and math ({\tt newtxmath}) package with roman text font provided by a Times clone, sans serif based on a \textsf{Helvetica} clone, typewriter faces, plus math symbol fonts whose math italic letters are from a Times Italic clone. As of version 1.4, {\tt newtxtext} no longer depends on {\tt txfonts} but is based on the richer source \textsf{TeXGyre Termes}, but {\tt newtxmath} continues to use the {\tt txfonts} math glyphs with many metric adjustments and some wholesale modifications.
+\textsc{Changes as of version 1.73}
+\begin{itemize}
+\item
+Superior letters and figures distinct from numerators have been added along with some special features. The text switch \verb|\sustyle| (or \verb|\sufigures|) or the commands \verb|\textsu|, \verb|\textsup|, \verb|\textsups| may be used to invoke ordinary superiors. The command \verb|\textsuperscript| is reserved for a form of superiors that respond to adjustments you may specify in the package options, and which are used for footnote marker typesetting: \verb|supscale| rescales them, \verb|supsraised| specifies an amount to move them vertically, and \verb|supLspaced|, \verb|supRspaced| specify additional kerning to be applied at the left and right. These changes are applied in the order: scaling, raising, kerning. All except \verb|supscale| should be dimensions with units like {\tt em} which will scale properly. Their relative vertical positions stack up like this: X\textinf{12}X\textde{345}X\textnu{678}X\textsu{90}.
+ There is also a {\tt supscolor} option that will apply a color specified in a form understood by {\tt xcolor}, like {\tt red!70!black}.
+% \item A word of warning---there is a difference between XeLaTeX and LuaLaTeX that is very irritating. When processing some of the commands where there may be a numeric argument, such as, for example, \verb|{\addfontfeature{VerticalPosition=Superior}5}|, the output will be as expected with XeLaTeX but not with LuaLaTeX if you have set the document figures to be anything but the default tabular, lining. This happens even though the {\tt sups} table has entries for all other forms ({\tt oldstyle}, {\tt taboldstyle} and {\tt lining}) of main body figures, and the {\tt sups} lookup is ahead of the {\tt lnum}, {\tt tnum}, {\tt onum} and {\tt pnum} lookups. (Similarly for the {\tt subs}, {\tt numr} and {\tt dnom} tables.) The only solution I can see for the moment is to undo any possible figure features other than tabular lining before adding another feature. I've done this in {\tt newtxtext.sty} for the basic commands, like the font switches \verb|\sustyle| and \verb|\infstyle|, and their related commands \verb|\textsu{}| and \verb|\textinf{}|, all of which are safe to use with both XeLaTeX and LuaLaTeX. (Likewise for \verb|\destyle|, \verb|\nustyle| and \verb|\textde{}|, \verb|\textnum{}|.)
+\item Option {\tt scosf}, which specifies oldstyle figure within small caps, has been extended and now works in all LaTeX engines with both the \verb|\scshape| switch and the macro \verb|\textsc{}|.
+\end{itemize}
\textsc{Very Important:} The math package changed substantially as of version 1.5, changing a number of glyphs, adding an option to reduce the sizes of large operators, and changing the integral signs to a choice of upright and slanted forms, each available in twelve variants. The new options are {\tt upint} (upright integrals) and {\tt smallerops} (smaller large operators.) Some previously available options may no longer have any effect. The changes are described in detail in the section on math mode options. A summary of the changes in version 1.5 is given in Appendix 1.
Version 1.60 likewise has many additions and changes that are summarized in Appendix 2. Most important is that {\tt newtx} is now able to output a PDF/A-1b compliant pdf using {\tt pdflatex}.

As of version 1.4, there are four normal figure styles: tabular lining, tabular oldstyle, proportional lining and proportional oldstyle, the default figure alignment being \texttt{tabular}. To make \texttt{proportional} the default, use the option \texttt{p} or \texttt{proportional}.

The Times superiors now contain the symbols often required for footnote marker symbols: \textsu{\textasteriskcentered\textdagger\textdaggerdbl\textsection\textparagraph\textbardbl}.
+
+The footnote marker macros in this package work with all LaTeX engines, and with the KOMA classes in all engines.
+Their position and spacing may be modified with the following options:
+\begin{itemize}
+\item
+{\tt supscaled} (or {\tt supscale}): a scale factor to apply to the marker.
+\item {\tt supsraised}:amount to raise the superiors baseline---should be in units like {\tt ex} so that they scale properly.
+\item
+{\tt supLspaced}: kerning to apply to the left of the superscript.
+\item
+{\tt supRspaced}: kerning to apply to the right of the superscript.
+\end{itemize}
+As of version 1.7, there are two additional figure forms having the same sizes as the superior figures: denominator figures aligned to the text baseline and inferior figures whose baseline lies below the text baseline. The latter may be called either with \verb|{\infigures 12345}| {\infigures 12345} or \verb|\textinf{6789}| \textinf{6789}, while denominator figures may be called with the font switches \verb|\defigures|, \verb|\destyle| or by the macro \verb|\textde|. Prior to version 1.7, these were arranged a little differently in LaTeX, and only for upright regular text. With version 1.7, these are available under all \LaTeX\ engines. There is also a much improved (at least in unicode latex) \verb|\textfrac| macro that builds a fraction from numerator and denominator figures: e.g., \verb|\textlf{5}\,\textfrac{7}{80}| renders as \textlf{5}\,\textfrac{7}{80}. The macro was changed starting in version 1.630 to add an optional argument for the integer part, and to allow adjustments to the space before and after the fraction solidus by means of the package options {\tt foresolidus} and {\tt aftsolidus}, which have no effect in unicode latex because they are not needed. Now, for example, \verb|\textfrac[5]{7}{80}| renders as \textfrac[5]{7}{80}.

+In version 1.724 this arrangement has been modified (with option {\tt newsu}, an abbreviation for \emph{new superiors}) whose effect is to leave numerator and denominator figures at the same sizes and positions as in 1.7, but adding larger (by 20\%) superiors and inferiors at revised vertical positions. I think the new superior size and position is more suitable for footnote markers than the old values. For a comparison of the two possibilities:\\ \verb|\textsup{1}\textnum{2}\textde{3}\textinf{4}| renders as \textsup{1}\textnum{2}\textde{3}\textinf{4} under option {\tt newsu} and as {\addfontfeature{VerticalPosition=Numerator}12}%
