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 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. Similarly, no matter what you chose as the default for upper and lower case Greek letters, \verb|\mathnormal{\beta}| and \verb|\mathnormal{\Omega}| will always produce the slanted versions. (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 1.44.)

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}.
\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.

-\textbf{Caution:} In encodings {\tt T1} and {\tt LY1}, the macro \verb|\mathrm| does not produce what you might expect for Greek letters, due to the difference between those encodings and {\tt OT1}. But what were you expecting with \verb|\mathrm{Gamma}| anyway? In {\tt T1} and {\tt LY1}, you'll get a math accent.

\section{Usage with Lua\LaTeX\ and Xe\LaTeX}
As far as I can tell, \textsf{newtxmath} works with both, but requires a very specific loading order and choice of options. Briefly, except for {\tt libertine} text, the math options must all be loaded prior to loading and using {\tt fontspec}. Be aware that some text packages (eg, {\tt cabin}) may contain a line like
