Option {\tt defaultsups} (same effect as {\tt defaultsups=true}) forces the package to use the \LaTeX\ default footnote markers (or, at least, those in force when the package is loaded) instead of those preferred by the package---Times Roman superior figures instead of spindly ordinary Times lining figures reduced to about 70\%. (Footnote markers in minipages use the default lowercase italic alphabetic characters, unless otherwise specified by redefining \verb|\thempfootnote|.) For better control over position and size of footnote markers, use the {\tt superiors} package after loading {\tt newtxtext}. The \verb|\sustyle| font switch and its related \verb|\textsu| macro know not only about figures, but also the lower case letters, including \texttt{egrave}, so that traditional French expressions like \textlf{1}\textsu{i\`ere} may be typeset correctly.
-As of version 1.625, there are now denominator figures (aligned to the text baseline) which may be called either with \verb|{\infigures 12345}| {\infigures 12345} or \verb|\textin{6789}| \textin{6789}. Currently, these are available only in regular weight, upright shape. There is a new macro \verb|\textfrac| that builds a fraction from superior figures and denominator figures: e.g., \verb|\textlf{5}\,\textfrac{7}{80}| renders as \textlf{5}\,\textfrac{7}{80}.

There is a new macro \verb|\textfrac| that builds a fraction from superior figures and denominator figures: e.g., \verb|\textlf{5}\,\textfrac{7}{80}| renders as \textlf{5}\,\textfrac{7}{80}. The macro was changed starting in version 1.630 to add an optional argument for the integer part, and to allow adjustments to the space before and after the fraction solidus by means of the package options {\tt foresolidus} and {\tt aftsolidus}. Now, for example, \verb|\textfrac[5]{7}{80}| renders as \textfrac[5]{7}{80}.

+Also, as of version 1.630, there is a custom \verb|\textcircled| macro that gives output very similar to the existing \verb|\textregistered| glyph. E.g., \verb|\textregistered\textcircled{S}\textcircled{2}| renders as \textregistered\textcircled{S}\textcircled{2}.
Option \texttt{largesc} changes the small cap glyphs from the default petite caps defined in TeXGyre Termes (same size as in txfonts) to a larger size that, in upright shapes, is metrically compatible with Adobe's small caps. These are about 10\% larger than petite caps. For a comparison, \textsc{Small Caps}, {\usefont{T1}{qtm}{m}{sc}Petite Caps}, and \textsc{\textit{Italic Small Caps}}, {\usefont{T1}{qtm}{m}{scit}Italic Petite Caps}.
