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.

+Changes in version 1.732
+1. Introduced a sequence of curly braces to replace standard braces if you specify
+the option curlybraces to newtxmath.
+2. Introduced three new math symbols: \laplace, \laplac and \dAlembertian. See the package documentation for details.

Changes in version 1.731
Removed zplsups-Regular-ts1.tfm from the newtx package as it conflicted with a file of the same name in newpx.

\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}.

+Version 1.732 introduces some new mathematical glyphs. First, there are new curly braces invoked by the option {\tt curlybraces} with {\tt height+depth} of 940, 1200, 1800, 2400, 3000 and 3600 em units. Second, there are three new math symbols:
+\begin{itemize}
+\item
+\verb|\laplace|, $\laplace$, which is an inverted \verb|\nabla|, having more weight in the bottom segment than \verb|\Delta|, $\Delta$.
+\item
+\verb|\laplac|, $\laplac$. This is the unicode-math name for the official d'Alembertian operator, {\tt U+29E0}. Unlike $\laplace$, it has more weight in the left and top segments than \verb|\laplace|.
+\item \verb|\dAlembertian|, $\dAlembertian$, rotates $\laplac$ by 180${}^\circ$, making for a glyph whose weight distribution is a better match for the Laplacian.
+\end{itemize}
% \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{}|.
