Version 1.60 likewise has many additions and changes that are summarized in Appendix 2. Most important is that {\tt newtx} is now able to output a PDF/A-1b compliant pdf using {\tt pdflatex}.

+Another important change took place in version 1.65, where {\tt theoremfont} was reimplemented using a new font family, {\tt ntxth} 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 newtxtext} 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 newtxtext}.

+\item \verb|\pagestyle{headings}| now functions as intended with slanted rather than upright figures in the headers.

This math package works, after possibly replacing its math Roman and Greek letters, with fonts other than Times that are intermediate in weight between Computer Modern and Times. The free font Linux Libertine is one particular target---it is of nearly the same x-height as Computer Modern, but, not being a \emph{modern} font, does not have a high contrast ratio, and so appears denser than Computer Modern but not as much so as Times. It is meant as a replacement for Times, but differs from it in many characteristics, more similar to MinionPro than Times, and provides a better range of variants than Times---three weights (regular, semi-bold and bold) rather than just two, and has expert features in all weights: old-style figures, more extensive and more interesting ligatures, and small caps. In my opinion, material typeset in Linux Libertine looks better than the corresponding material typeset in Times. This seems especially true on the screen. As of version 1.0, the package also offers support for MinionPro as a math font, but with limitations described in detail below. More recently, an option to provide math support for the \textsf{garamondx} text font package was added. Version 1.55 adds support for the {SticksToo} text fonts, a reworking of the {\tt STIX2} text fonts.

The option \texttt{osf} instructs the text fonts to use old-style figures \oldstylenums{1234567890} rather than the default lining figures $1234567890$. As of version $1.23$, {\tt newtxtext} loads initially with lining figures so the math package uses lining figures in math mode. The option {\tt osf} changes the default to old-style figures in text at the very end of the preamble, forcing the use of old-style figures in text, but not math. In earlier versions, it was necessary to run

+(New in version $1.65$.) Slanted text is now provided as part of the {\tt newtxtext} package, but requires that you specify the new option {\tt trueslanted}. Without this option, \verb|\textsl| will continue to behave as in earlier versions, outputting italic text with upright punctuation.

\section{Spacing issues}
This new version of {\tt newtxtext} has spacing that is a little different, in its default state, from that of the old {\tt newtxtext}. In small part this is due to the finer kerning of TeXGyre Termes, but mostly because the three parameters that govern inter-word spacing are not the same.
