 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 this version:
+Changes in version 0.94:
+1. Replaced upright italic glyphs in {\tt lettersA} by their Libertine equivalents, under the option libertine to newtxmath.
+2. Fixes to documentation and to my error in libertinealt.enc---thanks are due to Petri Lievonen for picking this up.
+3. Added option varbb to newtxmath to force the use of the variant BB alphabet.
+
+Changes in version 0.93:
 1. Added optical weights in math italic and math symbol fonts to improve rendering at small sizes.
 2. Changed the Linux Libertine math bold weight to their semibold (z) math italics and Greek.
 3. Commented out the old txfonts method for square roots---it did not space out as well as laTeX's method.

 \item {\tt varg} causes the math italic letters \verb|g,v,w,y| to be replaced by versions which are more distinctive---eg, useful for distinguishing math italic \verb|v| from \verb|\nu|;
 \item {\tt libertine} loads different versions of math italic and bold math italic based on \textsf{Libertine} rather than \textsf{Times}---the {\tt varg} option is disabled in this case, as the equivalent variant forms are made available by default;

 {\tt cmintegrals} instructs \textsf{newtxmath} to load a thicker version of the Computer Modern integral in place of the \textsf{newtxmath} default---the txfonts integral (identical to the integral in the Wolfram fonts), which is not to everyone's taste---a consequence is that none of the special forms of \textsf{txfonts} integrals are available;

 allows you to use the forms \verb|\iint|, \verb|\iiint|, \verb|\iiiint| and \verb|\idotsint| defined in {\tt amsmath}, but using the pumped-up Computer Modern integral loaded by {\tt newtxmath}. 
-\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}.
 \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.
 \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.
+\item The \textsf{newtxmath} package, like the original \textsf{txfonts}, contains two different Blackboard Bold alphabets, the default, triggered by \verb|\mathbb{}|, takes its glyphs from the font which replaces {\tt msam} and has the same overall appearance of a hollowed-out text font, which I find neither bold not blackboard-like. The other option, triggered by \verb|\varmathbb{}|, is more geometric and, in my opinion, preferable. The option {\tt varbb} makes \verb|\mathbb{}| behave like \verb|\varmathbb{}|.
+\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.)
