 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.

 \item {\tt uprightGreek} and {\tt slantedGreek} determine the form of Greek alphabet loaded---the default is {\tt uprightGreek}, which loads upright uppercase and slanted lowercase Greek symbols, as is customary in Anglo-American mathematical typesetting. With the option {\tt slantedGreek}, which you might want to use if you cared about ISO standards, all Greek symbols are slanted. No matter which is set, \verb|\Gammaup| (or \verb|\upGamma|) gives you upright \verb|\Gamma|, etc, and \verb|\Deltait|, \verb|\zetait| give you italic (i.e., slanted) versions of those letters. If you are using a text font family with properly constructed OT$1$--encoded versions, then, no matter what you chose as the default shape for upper case Greek letters, \verb|\mathnormal{\Omega}| etc will always produce the slanted version. (The macro \verb|\mathnormal| means essentially ``use the version of the symbol in {\tt letters}''---i.e., the math italic form. This did not always work as expected in versions prior to 1.45.) Currently, this works as expected with {\tt newtxtext} and {\tt libertine}. 
 \item Option {\tt frenchmath} sets the default style in math mode for rendering uppercase Roman and Greek letters to upright, and lowercase Greek letters to upright. (Introduced in v.\ 1.28.)
-\item The option {\tt cmbraces} instructs {\tt newtxmath} to ignore the brace collections from {\tt txfonts}, substituting a collection based on thickened versions of the Computer Modern braces, which I find much easier to distinguish from other delimiters. This works quite well in regular weight but looks a bit clunky in bold. I now prefer the option {\tt bigdelims}, which supersedes {\tt cmbraces}.

This works quite well in regular weight but looks a bit clunky in bold. The option {\tt bigdelims}, which superseded {\tt cmbraces}, is now not necessary---it is the default as of version 1.5.
+\item Option {\tt nonewtxmathopt} (or {\tt scale}, a mistake I cannot now erase) causes newtxmath to not make use of the optical math sizes (7{\tt pt}, 5{\tt pt}), as preferred by some.
+\item Option {\tt subscriptcorrection} enables the special spacing of some subscripts. (The default is {\tt nosubscriptcorrection}.)
 \item The \textsf{newtxmath} package contains three different Blackboard Bold alphabets, where original \textsf{txfonts} contained two. The default, triggered by \verb|\mathbb{}|, takes its glyphs from the font which replaces {\tt msbm} and has the same overall appearance of a hollowed-out text font, which I find neither bold nor blackboard-like. The second option, taken from \textsf{txfonts}, is triggered by \verb|\varmathbb{}|, is more geometric and, in my opinion, preferable but not optimal. The option {\tt varbb} makes \verb|\mathbb{}| synonymous with \verb|\varmathbb{}|. The third option is the double-struck glyphs from the STIX collection. See the expanded discussion below.
 \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}.)
-\item {\tt amssymbols} (the default) and {\tt noamssymbols} determine whether the {\tt txfonts} versions of the \textsc{ams} symbols ({\tt msam}, {\tt msbm}) 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.)

 \item {\tt libaltvw} has effect only if the libertine option is selected---in this case, it substitutes for math italic v and w hand-crafted versions based on the Libertine upsilon glyphs.
-\item{\tt bigdelims} loads a different math extension font and redefines most of the small and big math delimiters to have larger sizes so that, for example, there is more of a distinction between \verb|(| and \verb|\big(| in math mode. If this option is specified, {\tt cmbraces} is ignored.

+\subsection{Bold Math Italic macros}
+It can be a little awkward to specify bold math italic letters. This package defines macros of the form \verb|\BIA|---\verb|\BIz| that simplify this process, all based on the macro 
+\begin{verbatim}
+\DeclareRobustCommand{\BI@}[1]{%
+\begingroup\text{\mathversion{bold}$#1$}\endgroup}
+\end{verbatim}
+Following this, the package defines, e.g.,
+\begin{verbatim}
+\DeclareRobustCommand{\BIA}{\BI@{A}}
+\end{verbatim}
+so that \verb|\BIA| works as expected in all math styles (display, text, script, scriptscript). These macros may be copied with minor changes so that other alphabets may be specified similarly.

 \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.
