 This package, 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 1.23
+1. Added macros and glyphs for mathaccents \widearc and \wideOarc.
+2. Added code to newtxtext.sty so that option osf does not affect math use of lining figures, making \useosf unnecessary but harmless. (Thanks to Pablo González for this fine suggestion.)

 Changes in version 1.221
 Only change is to include latest verion of txex-bar.pfb, required for correct extensible parens.

+The option \texttt{osf} instructs the text fonts to use old-style figures \oldstylenums{1234567890} rather than the default lining figures $1234567890$. As of version $1.23$, {\tt newtxtext} loads initially with lining figures so the math package uses lining figures in math mode. The option {\tt osf} switches to old-style figures in text at the very end of the preamble, forcing the use of oldstyle figures in text, but not math. In previous versions, it was necessary to run 
+\verb|\useosf| after loading math. This is no longer required, but does no harm.
 
 Option {\tt defaultsups} (same effect as {\tt defaultsups=true}) forces the package to use the \LaTeX\ default footnote markers (or, at least, those in force when the package is loaded) instead of preferred by the package---Times Roman superior figures instead of spindly ordinary Times lining figures reduced to about 70\%. (Footnote markers in minipages use the default lowercase alphabetic characters, unless otherwise specified by redefining \verb|\thempfootnote|.) For better control over position and size of footnote markers, use the {\tt superiors} package after loading {\tt newtxtext}.

 \verb|\widehat| and \verb|\widetilde| have been extended from $3$ to $6$ sizes, and the smallest is now not as wide as in previous versions. In particular, you can now use, eg, \verb|$\widehat{X}^2$|, which gives $\widehat{X}^2$ without the hat colliding with the superscript.
-\item The math double bracket delimiters have been moved to another family so their use is less likely to cause a ``too many math families'' error. The orinary sizes now have their own macros, \verb|\dlb| and \verb|\drb|, giving, eg, $\dlb 0,T\drb$, as commonly used in probability theory.
