 \item Sans serif is by default taken from TeXGyreHeros, a Helvetica clone, and by default at 94\% of the scale factor (set by {\tt scaled}, default value {\tt1}).

+Option  {\tt theoremfont} was reimplemented using a new font family, {\tt npxth} instead of abusing \verb|\textsl|. By default,  users of {\tt theoremfont} will see no change in its functionality, including the use of the macro \verb|\textsl| to output italics with upright punctuation. A new option, {\tt trueslanted}, to {\tt newpxtext} has the following effects:
+\begin{itemize}
+\item
+\verb|\textsl| now outputs slanted text rather than italics with upright punctuation text, but not affecting the usage of the {\tt theoremfont} option to {\tt newpxtext}.
+\item the former behavior of \verb|\textsl| is now available through the new macro \verb|\textth|, \textsc{aka} \verb|\textthit|.
+\item \verb|\pagestyle{headings}| now functions as intended with slanted rather than upright figures in the headers.
