If this option is specified, {\tt cmbraces} is ignored. \item{\tt liby} has an effect only if the libertine option is selected---with this option, the math italic y is chosen to be Libertine's italic y instead of the default one from txfonts. +\item As of version $1.18$ of {\tt newtxmath} (and version $1.07$ of {\tt newpxmath}) there are new math accents and macros available. +\begin{itemize} +\item +\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. +\item The new macros \verb|\overgroup|, \verb|\undergroup|, \verb|\overgroupra|, \verb|\overgroupla|, \verb|\undergroupra| and \verb|\undergroupla| are intended as replacements for the \verb|\wideparen|, \verb|\widearc| and related macros from the \textsf{yhmath} and \textsf{fourier} packages. In fact, \verb|\overgroup| and \verb|\undergroup| are variants of \verb|\overbrace| and \verb|\underbrace|, while the suffices {\tt ra} and {\tt la} signify right arrow and left arrow respectively. The macro \verb|\widering| places a ring centered over an \verb|\overgroup|, not dissimilar from its use in {\tt yhmath}. Examples: +\begin{verbatim} +\[\overgroup{ABC}\quad\overgroupra{ABC}\quad\undergroup{ABC}\quad +\undergroupla{ABC}\quad \widering{ABCD}\] +\end{verbatim} +gives +\[\overgroup{ABC}\quad\overgroupra{ABC}\quad\undergroup{ABC}\quad\undergroupla{ABC}\quad\widering{ABCD}\] +\end{itemize} + %\item {largelibfigs} has effect only if the libertine option is selected---with this option, full-sized figures are substituted in math mode for the default Libertine figures, which are about 8\% below Libertine's Capheight. \end{itemize} +\bigskip + \textbf{IMPORTANT:} The Libertine text package is now once again named {\tt libertine}, but requires arguments that are different from the original {\tt libertine} package. \textsc{Example 1:} |
