\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.

\subsection{Archivability}
-Some of the individual font files from which the math fonts are built turned out to have some fairly minor structural issues. These have all been corrected. The more major issue was the lack of unicode mapping for all characters in the fonts. For the symbol and math extension fonts, this issue was largely solved by Ross Moore's {\tt glyphtounicode} files that are now accessible as part of TeXLive and MiKTeX. The main problem was the math alphabets like math italic, bold math italic, upright Greek and slanted Greek, all of which have now been assigned their own unicode points. For all of these, I constructed new fonts using unicode names for the glyphs, then made \textsf{fontinst} scripts that renamed those unicode values to the original simple names as used in the encoding files so that I could use my old encoding and adjustment files. This exercise has now been carried out for {\tt newtxmath}, {\tt newpxmath}, {\tt newtxmath/libertine}, {\tt newtxmath/stix2} and {\tt newtxmath/xcharter.} Each of these can now be considered to have an ``enhanced'' status that allows them to share all the new assets described below. The other packages which may be specified as an option to {\tt newtxmath} (e.g., {\tt cochineal, baskervillef}) must be considered for the moment to be ``unenhanced'' and able to share only some of the new assets. In particular, only the enhanced items can generate archivable pdf.

Enhancement is for the moment only partial with {\tt newtxmath/utopia}, as conformance to PDF/A-1b is not likely, but the additional alphabets are present.

In particular, only the enhanced items can generate archivable pdf.
Also modified were the {\tt sups} fonts in {newtxtext}, where the main issue was unicode mapping. Superior number and some superior letters do have assigned unicode values, but in may cases a more creative approach was needed, and provided once again by Ross Moore. I rebuilt the superior font files using those unicode names, solving that particular problem.
