 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{The new {\tt newtx.sty}}
+Versions 1.7--1.71 added the ability to process {\tt.tex} documents with all current LaTeX engines, adding {\tt fontspec} based macros as replacements for macros and options formerly defined for non-unicode {\tt latex} processing as needed for unicode latex processing. A new option, {\tt thmslshape}, instructs {\tt theoremfont} to use slanted rather than italic shape, with upright punctuation, of course. There are some new macros and options that work only under unicode LaTeX. The {\tt newtxtext} package is modified very substantially to work for all latex engines.

+Also introduced in 1.7 is {\tt newtx.sty}, which to some extent reduces the (human) memory requirements for loading {\tt newtxtext} and/or {\tt newtxmath} in a way that works with all LaTeX engines. 
+
+\textbf{Basic {\tt newtx} options:}
+ 
+\begin{itemize}
+\item
+{\tt type1text} (or {\tt type1} specifies that text processing should use a type1 package. (The default is to use an otf text package if processing with a unicode engine. With a non-unicode engine, a type1 text package is the default.)
+\item {\tt otfmath} specifies to use an otf math engine rather than the default type1 math package, {\tt newtxmath}.
+\item Option {\tt scale} or {\tt scaled} will pass the same {scale} option to both the text package and  {\tt newtxmath}.
+\item For dealing with cases where the text package should be loaded with a different scale from {\tt newtxmath}, you specify separately the options {\tt textscale[d]} and {\tt mathscale[d]}. There is one useful special case to notice: the option {\tt textscale[d]=0} selects a text scale factor that matches to the math scale factor, the latter defaulting to 1 unless otherwise specified.
+\item You may specify as an option to {\tt newtx} any option valid for {\tt newtxmath}: those are mostly passed directly to {\tt newtxmath}. These will have no effect if you specify a unicode math package.
+\item Other options are passed along to the text package, with the exception of a few  handled by {\tt newtx}.
+\end{itemize}
+
+The effect of loading the {\tt newtx} package is fundamentally one of four types, depending on the options you specify and the processing engine.

+The sty file {\tt newtx.sty} stores a good deal of information about each of the supported text packages and uses some of this to translate its macros into forms understood by the text package.
 
-You may specify any option to {\tt newtxtext} or {\tt newtxmath} as an option to {\tt newtx}: it will simply pass them along to those packages for processing.
+For example, how the following line in your preamble is interpreted depends on the LaTeX engine and the options you set. 
+\begin{verbatim}
+\usepackage[libertine,vvarbb]{newtx}
+\end{verbatim}
+With non-unicode engines such as {\tt latex+dvips} or {\tt pdflatex}, the result will be the same as would be produced by

+  \usepackage[vvarbb]{newtxmath} % vvarbb was passed from newtx
+  \usepackage{libertine} % should load tt and sans math before newtx
+\end{verbatim}
+The first line, setting the \verb|\rmdefault| temporarily to {\tt minlibertine}, refers to  one of three {\tt fd} files included with the distribution: {\tt t1minlibertine.fd}, {\tt ot1minlibertine.fd}, {\tt ly1minlibertine.fd}, and the one used depends on the last encoding specified before {\tt newtx} with a line like
+\begin{verbatim}
+\usepackage[T1]{fontenc}
+\end{verbatim}
+If you look at, say, {\tt t1minlibertine.fd} (the ``min'' part of the name is supposed to denote ``minimal''), you will see that if leads to {\tt libertine} text fonts with TLF (Tabular Lining Figures). When {\tt newtxmath} is loaded it is sets its {\tt operators} fonts to the corresponding {\tt libertine} text font so that mathematical operator names, numerals, punctuation and accents are chosen from this font. Indeed, this is the only way it will be used.
 
-A more realistic preamble would follow the general pattern:
+Finally, the actual text font package, {\tt libertine}, is loaded with whatever is selected by the text options you specified. For example, if your options specified to {\tt newtx} included {\tt p, osf}, then all figures in text (but not in math) would be in proportional oldstyle shape.
+
+There is a ``min'' fd family for each possible text font family, each pointing to TLF figured tfm files, but using a family name that will not conflict in any way with the final text font family. Examples are {\tt minntx} (for {\tt newtxtext}), {\tt minetbb} and so on.

+%As far as I can tell, \textsf{newtxmath} works with both, but requires a very specific loading order and choice of options. Briefly,  the math options must all be loaded prior to loading and using {\tt fontspec}. As of version 1.5, {\tt newtxtext} will load fontspec when processing with XeLaTeX or LuaLaTeX unless one or more of the options {\tt nofontspec}, {\tt type1} is specified. (If you specify the option {\tt no-otfmath} to {\tt newtxtext}, it will pass the option {\tt no-math}to the {\tt fontspec} call. This should be done if  {\tt fontspec} will not be expected to load an Opentype package or install  math support using {\tt mathspec}.)

-It is not necessary to use {\tt newtx} in version 1.7 and higher. The original loading via {\tt newtxtext} and {\tt newtxmath} should still work.
+\subsection{The stacked fraction macro}
+Having collected a lot of data about the text fonts it supports, it seemed worth-while to construct a macro that would work for most of those fonts: \verb|\textsfrac[1]{17}{32}| renders in {\tt newtxtext} as \textsfrac[1]{17}{32} and \verb|\textsfrac{9}{64}| as \textsfrac{9}{64}. Compare these with output from the diagonal fraction macro \verb|\textfrac|: \textfrac[1]{17}{32}, \textfrac{9}{64}.
 
-The math package {\tt newtxmath} works, after possibly replacing its math Roman and Greek letters, with fonts other than Times that are intermediate in weight between Computer Modern and Times. The free font Linux Libertine is one particular target---it is of nearly the same x-height as Computer Modern, but, not being a \emph{modern} font, does not have a high contrast ratio, and so appears  denser than Computer Modern but not as much so as Times. It is meant as a replacement for Times, but  differs from it in many characteristics, more similar to MinionPro than Times, and provides a better range of variants than Times---three weights (regular, semi-bold and bold) rather than just two, and has expert features in all weights: old-style figures, more extensive and more interesting ligatures,  and  small caps. In my opinion, material typeset in Linux Libertine looks better than the corresponding material typeset in Times. This seems especially true on the screen. As of version 1.0, the package also offers support for MinionPro as a math font, but with limitations described in detail below. More recently, an option to provide math support for the \textsf{garamondx} text font package was added. Version 1.55 adds support for the {SticksToo} text fonts, a reworking of the {\tt STIX2} text fonts.
+There are four options with which you may control the layout of the fractional part.
+\begin{itemize}
+\item
+{\tt sfracvcenter} controls the vertical center of the fraction bar.
+\item{\tt sfracbarthick} controls its thickness.
+\item{\tt sfracvspacing} controls the vertical space about and below the fraction bar.
+\item{\tt sfracscaling} controls the size of the figures in the fraction.
+\end{itemize}
+The last of these is just a number like .85 by which to scale the denominator figures used in the construction. The first three items may be specified in either {\tt em} units or in {\tt ex} units. If you use a number greater than 6, it is interpreted as a multiple of an {\tt em} (recall that for most fonts, and certainly for those supported by {\tt newtx}, 100{\tt em} is equal to 1{\tt pt} if you are processing at 10pt. On the other hand, 1{\tt ex} is the height of the letter x in the current text font. If you specify a number less than 6, it is interpreted in {\tt ex} units.
 
+\subsection{Limitations of {\tt newtx}}
+
+1. When using {\tt newtx} with a unicode engine and specify the option {\tt otfmath}, the only text font you will have available is {\tt newtxtext}. You may specify another package, but {\tt newtx} will change it back to {\tt newtxtext} and issue a message to the console and the {\tt log} file.
+
+2. You can't use an arbitrary text font with {\tt newtx}. It needs considerable information to be available including how to pair it to a variant of {\tt newtxmath}.
+
+3. Aside from the minor addition of the stacked fraction macro \verb|\textsfrac|, {\tt newtx} is simply a convenience: it loads packages and sets option so that you don't have to remember as many details.
+The original loading via {\tt newtxtext} and {\tt newtxmath} should still work as long as you remember all the loading rules.
+
+\section{Newtxmath}
+The math package {\tt newtxmath} works, after possibly replacing its math Roman and Greek letters, with fonts other than Times that are intermediate in weight between Computer Modern and Times. The free font Linux Libertine is one particular target---it is of nearly the same x-height as Computer Modern, but, not being a \emph{modern} font, does not have a high contrast ratio, and so appears  denser than Computer Modern but not as much so as Times. It is meant as a replacement for Times, but  differs from it in many characteristics, more similar to MinionPro than Times, and provides a better range of variants than Times---three weights (regular, semi-bold and bold) rather than just two, and has expert features in all weights: old-style figures, more extensive and more interesting ligatures,  and  small caps. In my opinion, the venerable {\tt libertine} package should at this point be substituted by the newer {\tt libertinus} package. As of version 1.0, {\tt newtx} also offers support for MinionPro as a math font, but with limitations described in detail below. More recently, an option to provide math support for the \textsf{garamondx} text font package was added. Version 1.55 adds support for the {SticksToo} text fonts, a reworking of the {\tt STIX2} text fonts.

 Fontspec  offers the {\tt WordSpace=} option for individual control of the space, stretch and shrink, with the value being either an ordered triple like \verb|{1.1,1,.8}| or a single number like {\tt .9}, the latter having the same effect as the triple \verb|{.9,.9,.9}|. These three numbers act as multipliers of {\tt space}, {\tt stretch} and {\tt shrink}.

 \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}.) If this option is selected, then, as of version 1.53, new definitions are made for the missing negated symbols. The package {\tt centernot} is now required.
 %\item {\tt amssymbols} (the default) and {\tt noamssymbols} determine whether the {\tt txfonts} versions of the \textsc{ams} symbols ({\tt AMSm}) 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 two of your precious math families for other purposes, such as setting a couple of external math alphabets by means of the \textsf{mathalfa} package.) \textbf{Important note:} if you load an AMS class, like {\tt amsart}, then some trickery will be involved. From 2018 onward, the AMS classes {\tt noamsfonts}  prevents the loading of {\tt AMSa} and {\tt AMSb}, which waste two slots. 
 %The following workaround seems like a reasonable stopgap until then.

Increasing the left side-bearing of j, etc., helps with superscripts but creates an ugly gap when used as subscripts.

+%\subsection{Operatorname issues}
+%For some of the text fonts supported by {\tt newtx}, an {\tt OT1} version of the text fonts has been constructed with Greek capital letters in the first eleven slots, just as in Computer Modern, and some older TeX constructs depend on that. In those cases, even if you set {\tt T1} as your text font encoding before loading {\tt newtxmath} or {\tt newtx}, the operator font will be set to the {\tt OT1} version, not the {\tt T1} version. (You may prevent this by specifying option {\tt noOT1} to {\tt newtxmath} or {\tt newtx}.) Using the {\tt OT1} encoded operators font should not be a problem unless you wish to use accented characters in some operator names. This is the case in Spanish and Portuguese, and possible other languages. One solution could be to define the affected operators individually with commands like
