+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:

+\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|.
