 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 1.641
+1. Corrected some metrics problems with the version of  the STIX BB fonts used in this package.
+2. Corrected two math glyphs: odot in symbols at 7pt and big right bracket in bold mathex. (Thanks Davide Campagnari.)
+3. Added lower case letters to the BB alphabet addressed by the option varbb.
+4. The same  corrections now apply to all related packages for which there is an "enhanced" math option to newtx.

 Changes in version 1.640
 1. Added several Blackboard Bold Greek glyphs.
 2. Substantially modified the handling of Blackboard Bold and Math Script, both simplifying code and correctly conflicts with bolding macros and hyperref.

 2. Corrected an error in newtxmath.sty which affected the rendering of Bbb figures under the option stickstoo.
 3. Corrected some problems with LY1 encodings affecting superior letters and figures, and one of the TS1 encodings.
 4. Added a replacement for the default \textfrac command which did not give satisfactory results with the newtx fonts.
-5. Replaced the previous definition of \textfrac what I think is a better one, but remaing backwards compatible with the previous version.

 Changes in version 1.629
 Added math support for NotoSerif and NotoSans.  See the documentation for the new package notomath, which integrates this support.

+The second possible alphabet may be specified by  the option {\tt varbb}, looking like $\varmathbb{ABC...k}$. It does cooperate with the bolding macro \verb|\bm| and with \verb|hyperref| but, in my opinion, it has appearance problems. It has all uppercase letters, but in versions of {\tt newtx} up to $1.640$, its only lowercase glyph is $\varmathbb{k}$. As of version $1.641$, there is a full lowercase plus \verb|\imath| and \verb|\jmath|. The bold version is identical to the regular version.
 \item
 The third possibility is specified by  the option {\tt vvarbb}, looking like $\vvmathbb{ABC...Za...z0...9}$. It cooperates with the bolding macro \verb|\bm| and with \verb|hyperref| and, in my opinion , looks better than the other two. It is taken from the original STIX math fonts. There is a slightly heavier bold version.
 \item No matter which alphabet option you chose, you may use symbols from of of the variant alphabets by means of the macros \verb|\vmathbb|, \verb|\vvmathbb|: e.g., \verb|\vmathbb{N}| gives $\vmathbb{N}$ and \verb|\vvmathbb{C}| gives $\vvmathbb{C}$. Note that for consistency with earlier usage in {\tt newtxmath}, \verb|\varmathbb| is a synonym for \verb|\vmathbb|.
-\item In each of the two variant alphabets, there are digits as well as dotlessi and dotlessj, all taken from the STIX Blackboard Bold alphabets.

 \item \textbf{Important note:} Under the option {\tt stix2}, there are still three blackboard fonts but the macro \verb|\vmathbb| now points to glyphs from {\tt DSSerif}, a serifed double-struck family that replaces the original variant that is still available under other options. With {\tt stix2}, the {\tt dotlessi} and {\tt dotlessj} glyphs from the {\tt DSSerif} font are available as \verb|$\imathbbs$| and \verb|$\jmathbbs$|, no matter which blackboard bold option you chose.
 \end{itemize}
 One interesting feature of the third Blackboard Bold alphabet is that it contains blackboard bold numbers, of which $0$ and $1$ will likely be the most useful, perhaps as operator names. I find $\vvmathbb{1}$=\verb|$\vvmathbb{1}$| useful in specifying an indicator, AKA characteristic function. Here are some examples that hold except with the {\tt stix2} option:

+There are also interactions with {\tt pstricks} that have to be worked around because {\tt subscriptcorrection} redefines \verb|_| as an active character, as do parts of {\tt pstricks}. In particular, the {\tt pstricks} short forms for macros like \verb|\tbput| and \verb|\nbput| for attaching labels beneath node connections must be avoided.

 If you do enable {\tt subscriptcorrection}, there is a default correction table in the {\tt sty} file, but the sty file also looks for a file named, e.g., {\tt newtx-subs.tex} if you are using the {\tt newtx} default math letters. There is already such a file located in the {\tt newtx} distribution in the \verb|/tex/latex/| folder.
