+\NEWdescription{2019/10/15}
+\NFSS{} forces you to give all declarations in a specific order so

+complain. Here are the dependencies that you have to obey:
+\begin{itemize}
+\item
+|\DeclareFontFamily| checks that the encoding scheme was previously
+declared with |\DeclareFontEncoding|.
+
+\item
+|\DeclareFontShape| checks that the font
+family was declared to be available in the requested
+encoding (|\DeclareFontFamily|).
+
+\item
+|\DeclareSymbolFont| checks that the encoding scheme is valid.
+
+\item
+|\SetSymbolFont| additionally ensures that the requested math
+version was declared (|\DeclareMathVersion|) and that the requested
+symbol font was declared (|\DeclareSymbolFont|).
+
+
+\item
+|\DeclareSymbolFontAlphabet| checks that the command name for the
+alphabet identifier can be used and that the symbol font was declared.
+
+\item
+|\DeclareMathAlphabet| checks that the chosen command name can be
+used and that the encoding scheme was declared.
+
+\item
+|\SetMathAlphabet| checks that the alphabet identifier was
+previously declared with |\DeclareMathAlphabet| or
+|\DeclareSymbolFontAlphabet| and that the math version and the
+encoding scheme are known.
+
+\item
+|\DeclareMathSymbol| makes sure that the command name can be used
+(i.e., is undefined or was previously declared to be a math symbol)
+and that the symbol font was previously declared.
+
+\item
+When the |\begin{document}| command is reached, \NFSS{} makes
+some additional checks---for example, verifying that substitution
+defaults for every encoding scheme point to known font shape group
+declarations.

-Since the finalisation of \eTeX{} in 1999, a number of additional `utility'
-primitives have been added to \pdfTeX{}. Several of these are broadly useful
-and have been requirements for \pkg{expl3} for some time, most notably
-\cs{pdfstrcmp}. Over time, a common set of these `post-\eTeX{}' primitives have
-been incorporated into \XeTeX{} and (u)p-\TeX{}; they were available in
-\LuaTeX{} already.

+\section[Improvements to \LaTeX{}'s font selection\\ mechanism (NFSS)]
+ {Improvements to \LaTeX{}'s font selection\\ mechanism (NFSS)}
+
+
+\subsection{Extending the shape management of NFSS}
+
+Over time more and more fonts have become available for use with
+\LaTeX{}. Many such font families offer additional shapes, e.g., small
+caps italics (\texttt{scit}), small caps slanted (\texttt{scsl} or
+swash letters (\texttt{sw}). By using \cs{fontshape} those shapes can
+be explicitly selected and for the swash letter shapes there is also
+\cs{swshape} and \cs{textsw} available.
+
+In the original font selection implementation a request to select a new shape
+always overrode the current shape. With the 2020 release of \LaTeX{}
+this has changed and \cs{fontshape} can now be used to combine small
+capitals with italics, slanted or swash letters, either by explicitly
+asking for \texttt{scit}, etc., or by asking for italics when typesetting
+already in small caps and so forth.
+
+Using \cs{upshape} will still change italics or slanted back to an
+upright shape but will not any longer alter the small caps setting. To
+change small capitals back to upper/lower case you can now use
+\cs{ulcshape} (or \cs{textulc}) which in turn will not change the font
+with respect to italics, slanted or swash.
+%
+There is one exception: for compatibility reasons \cs{upshape} will
+change small capitals back to upright (\texttt{n} shape), if the
+current shape is \texttt{sc}. This is done so that something like
+\cs{scshape}\allowbreak\texttt{...}\allowbreak\cs{upshape} continues
+to work, but we suggest that you don't use that deprecated method in
+new documents.
+
+Finally, if you want to
+reset the shape back to normal you can use \cs{normalshape} which is a
+shorthand for \cs{upshape}\cs{ulcshape}.
+
+The way that shapes combine with each other is not hardwired but is
+customizable and extensible if there is ever a need for it. The
+mappings are defined through \cs{DeclareFontShapeChangeRule} and the
+details for developers are documented in \texttt{source2e.pdf}.
+
+The ideas for this interface extension have been pioneered in
+\pkg{fontspec} by Will Robertson for Unicode engines and in
+\pkg{fontaxes} by Andreas Bühmann and Michael Ummels for \pdfTeX{} and
+used in many font support packages.
+
+
+
+\subsection{Extending the series management of NFSS}
+
+Many of the the newer font families also come provided with additional
+weights (thin, semi-bold, ultra-bold, etc.\@) or several running lengths
+such a condensed or extra-condensed. In some cases the number of
+different series values is really impressive, for example, Noto Sans
+offers 36 fonts from ultra-light extra condensed to ultra-bold medium width.
+
+Already in its original design, NFSS supported 9 weight levels from
+ultra-light (\texttt{ul}) to ultra-bold (\texttt{ub}) and also 9 width
+levels from ultra-condensed (\texttt{uc}) to ultra-expanded
+(\texttt{ux}) so more than enough even for a font family like Noto
+Sans. Unfortunately, some font support packages nevertheless invented
+their own names so in recent years you could find all kinds of
+non-standard series names like \texttt{k}, \texttt{i}, \texttt{j} and
+others making it impossible to combine different fonts successfully
+using the standard NFSS mechanisms.
+
+Over the course of the last year a small number of individuals,
+notably, Bob Tennent, Michael Sharpe and Marc Penninga worked hard to
+bring this unsatisfying situation back under control and today we are
+happy to report that the internal font support files for more than a
+hundred font families are back to following the standard NFSS conventions
+so that combining them is now again rather nice and easy (of course,
+there is still the task of choosing combinations that visually work
+well together, but from a technical perspective they can now easily
+matched).
+
+
+In the original font selection implementation, a request to select a new series
+always overrode the current one. This was reasonable because there
+were nearly no fonts available that offered anything other than a
+medium or a bold series. Now that this has changed and families such
+as Noto Sans are available, combining weight and width into a single
+attribute is no longer appropriate. With the 2020 release of \LaTeX{}
+the series management therefore changed to allow for independently
+setting the weight and the width attribute of the series.
+
+For most users this change will be largely transparent as \LaTeX{}
+offers only \cs{textbf} or \cs{bfseries} to select a bolder face (and
+\cs{textmd} and \cs{mdseries} to return to a medium series) but no
+high-level command for selecting a condensed face, etc. However, with
+the NFSS low-level interface, it is now possible to ask for, say,
+\verb=\fontseries{c}\selectfont= in a marginal note to get a condensed
+face and that would still allow using \cs{textbf} inside. This then would
+select a bold condensed face and not a rather odd-looking
+bold-extended face in the middle of condensed type.
+
+The expectation is that this functionality is largely used by class and package
+designers, but given that the low-level NFSS commands are usable on
+the document level and not really difficult to apply, there are
+probably also a number of users who will enjoy using the new
+possibilities that bring \LaTeX{} back into the front league when it
+comes to font usage.
+
+The way different series values combine with each other is not
+hardwired but is again customizable and extensible. The mappings are
+defined through \cs{DeclareFontSeriesChangeRule} and the details for
+developers are documented in \texttt{source2e.pdf}.
+
+
+
+\subsection{Font series defaults per document family}
+
+With additional weights and widths available in many font families it
+becomes more likely that somebody wants to match, say, a medium weight
+serif family with a semi-light sans serif family or that with one
+family one wants to use the bold-extend face when \cs{textbf} is used
+while with another it should be bold (not extended) or semibold, etc.
+
+In the past this kind of extension was made available with the
+\pkg{mweights} package by Bob Tennent which has been used in many font
+support packages.
+
+With the 2020 release of \LaTeX{} this feature is now available out
+of the box. In addition we also offer a document-level interface to adjust the
+behavior of the high-level series commands \cs{textbf}, \cs{textmd} and their
+declaration forms \cs{bfseries} and \cs{mdseries} so that they can
+have different effects for the serif, sans serif and typewriter
+families used in a document.
+
+For example, specifying
+\begin{verbatim}
+ \DeclareFontSeriesDefault[rm]{bf}{sb}
+ \DeclareFontSeriesDefault[tt]{md}{lc}
+\end{verbatim}
+in the document preamble would result in \cs{textbf} producing
+semi-bold (\texttt{sb}) when typesetting in roman typeface and
+that typewriter is by default (medium series \texttt{md}) using
+a light-condensed face. The optional argument here can be either
+\texttt{rm}, \texttt{sf} or \texttt{tt} to indicate one of the three
+main font families in a document; if omitted you will change the
+overall document default instead. In the first mandatory argument you
+specify either \texttt{md} or \texttt{bf} and the second mandatory
+argument then gives the desired series value in NFSS nomenclature.
+
+
+\subsection{Emphasis handling generalized}
+
+With previous releases of \LaTeX{} nested \cs{emph} commands
+automatically alternated between italics and upright. This mechanism
+has now been generalized and you can now specify for arbitrary nesting
+levels how emphasis should be handled.
+
+The declaration \cs{DeclareEmphSequence} expects a comma separated
+list of font declarations corresponding to increasing levels of
+emphasis. For example,
+\begin{verbatim}
+ \DeclareEmphSequence{\itshape,%
+ \upshape\scshape,\itshape}
+\end{verbatim}
+uses italics for the first, small capitals for the second, and italic
+small capitals for the third level (provided you use a font that
+supports these shapes). If there are a more nesting levels than
+provided, \LaTeX{} uses the declarations stored in \cs{emreset} (by
+default \cs{ulcshape}\cs{upshape}) for the next level and then
+restarts the list.
+
+The mechanism tries to be \enquote{smart} and verifies that the given
+declarations actually alter the current font. If not it continues and
+tries the next level---the assumption being that there was already a
+manual font change in the document to the font that is now supposed to
+be used for emphasis.
+%
+Of course, this only works if the declarations in the list entries
+actually change the font and not, for example, just the color. In such
+a scenario one has to add \cs{emforce} to the entry which directs the
+mechanism to use the level, even if the font attributes appear to be
+unchanged.
+
+
+
+\subsection{Providing font family substitutions}
+
+Given that \pdfTeX{} can only handle fonts with up to 256 glyphs a
+single font encoding can only support a few languages. The \texttt{T1}
+encoding, for example, does support many of the Latin based scripts,
+but if you want to write in Greek or Russian you need to switch
+encodings to \texttt{LGR} or \texttt{T2A}. Given that not every font
+family offers glyphs in such encodings, you may end up with some
+default family (e.g., Computer Modern) that doesn’t blend in well
+chosen document font. For such cases NFSS now offers
+\cs{DeclareFontFamilySubstitution}, for example:
+\begin{verbatim}
+ \DeclareFontFamilySubstitution{LGR}
+ {Montserrat-LF}{IBMPlexSans-TLF}
+\end{verbatim}
+tells \LaTeX{} that if you are typesetting in the sans serif font
+\texttt{Montserrat-LF} and the Greek encoding \texttt{LGR} is asked
+for, then \LaTeX{} should use \texttt{IBMPlexSans-TLF} to fulfill the
+encoding request.
+
+The code is based on ideas from the \pkg{substitutefont}
+package by Günter Milde, but implemented differently.
+
+
+\subsection{Providing all text companion symbols by default}
+
+The text companion encoding \texttt{TS1} was originally not available
+by default, but only when the \pkg{textcomp} package was loaded. The
+main reason for this was limited availability in fonts other than
+Computer Modern and memory restrictions back in the nineties. These
+days neither limitation exists any more so with the 2020 release all
+the symbols provided with the \pkg{textcomp} package are available out
+of the box.
+
+Furthermore, an intelligent substitution mechanism has been
+implemented so that missing glyphs are automatically substituted with
+defaults that are sans serif if you typeset in \cs{textsf} and
+monospaced if you typeset using \cs{texttt} and not always serifed.
+
+
+\textsf{This is most noticeable with \cs{oldstylenums} which are now
+ taken from \texttt{TS1} so that you no longer get
+ \textrm{\oldstylenums{123}} but \oldstylenums{123} when typesetting
+ in sans serif fonts}\texttt{ and \oldstylenums{123} when using
+ typewriter fonts.}
+
+If there ever is a need to use the original (inferior) definition,
+then that remains available as \cs{legacyoldstylenums} and to fully
+revert to the old behavior there is also
+\cs{UseLegacyTextSymbols}. That declaration reverts \cs{oldstylenums}
+and also changes the footnote symbols, such as \cs{textdagger},
+\cs{textparagraph}, etc.\ pick up their glyphs again from the math
+fonts instead of the current text font (this means they always keep
+the same shape and do not nicely blend in with the text font).
+
+With the text companion symbols as part of the kernel it is normally
+no longer necessary to load the \pkg{textcomp} package, but for
+backwards compatibility this package will remain available. There is,
+however, one use case where it remains useful: if you load the package
+with the option \texttt{error} or \texttt{warn} then substitutions
+will change their behavior and result in a \LaTeX{} error or a
+\LaTeX{} warning (on the terminal), respectively. Without the package
+the substitution information only appears in the \texttt{.log}
+file. If you use the option \texttt{quit}, then even the information in
+the transcript is suppressed (which is not really recommended).
+
\section{Other changes to the \LaTeX{} kernel}
-\emph{fixed gh198}
+\subsection{New \texttt{alias} size function for use in \texttt{.fd} files}
+Most of the newer fonts supported in \TeX{} have been set up with the
+\texttt{autoinst} tool by Marc Penninga. In the past this program did
+set up the font faces using the face names chosen by its designer,
+e.g., \enquote{\texttt{regular}}, \enquote{\texttt{bold}}, etc., and
+then mapped those via substitution to the standard NFSS shape names,
+i.e., \enquote{\texttt{m}} or \enquote{\texttt{b}}. As a result one
+got unnecessary substitution warnings such as \enquote{\texttt{Font
+ T1/abc/bold/n not found using T1/abc/b/n instead}}.
-\section{Changes to packages in the \pkg{tools} category}
+We now provide a new NFSS \texttt{alias} size function that can and will be
+used by \texttt{autoinst} in the future. It provides the same
+functionality as the \texttt{subst} function but is less vocal about
+its actions, such that only relevant font substitutions show up as
+warnings.
+
+
+
+
+
+\subsection{UTF-8 characters in package descriptions}
+
+In 2018 we made UTF-8 the default input encoding for \LaTeX{} but we
+overlooked the case of package descriptions in declarations such as
+\cs{ProvidesPackage} which worked (sometimes) before but now died
+always. This has been corrected.
+\githubissue{52}
+
+
+\subsection{Suppress unnecessary font substitution warnings}
-\emph{fixed gh190}
+Many sans serif fonts do not have real italics but usually only
+oblique/slanted shapes, so the substitution of slanted for italics is
+natural and in fact many designers talk about italic sans serif faces
+even if in reality they are oblique. With nearly all sans serif font
+family the \LaTeX{} support files therefore silently substitute
+slanted if you ask for \cs{itshape} or \cs{textit}. This is also true
+for Computer Modern in \texttt{T1} encoding but in \texttt{OT1} you
+got a warning on the terminal even though there is nothing you can do
+about it. This has now been changed to an information message only
+written to the \texttt{.log} file.
+%
+\githubissue{172}
+
+
+\subsection{Fix inconsistent hook setting when loading packages}
+
+When a package is loaded
+\texttt{\textbackslash}\textit{package}\texttt{.sty-h@@k} is set, but
+it was loaded several times it was unset again. Relevant only to
+package developers.
+%
+\githubissue{198}
+\subsection{Avoid spurious warning if \texttt{LY1} is made the default encoding}
+
+Making \texttt{LY1} the default encoding as done by some font support
+packages gave a spurious warning even if \cs{rmdefault} was changed
+first. This was corrected.

-\section{Changes to packages in the \pkg{amsmath} category}
+\subsection{Ensure that \cs{\textbackslash} remains robust}
+In the last release we made most document-level commands robust, but
+\cs{\textbackslash} became fragile again if \cs{raggedright}
+typesetting was used.
+%
+\githubissue{203}
-\section{Documentation updates}
+\subsection{Allow more write streams with \texttt{filecontents} in \LuaTeX}
+
+Most \TeX{} engines only support a maximum of sixteen concurrently
+open write streams and if those have been used up, then
+\texttt{filecontents} or any other code trying to open another one
+will fail. In \LuaTeX{} more write streams are available and those can
+now be utilized as well.
+%
+\githubissue{238}
+\section{Changes to packages in the \pkg{graphics} category}
+
+\subsection[Make \pkg{color}/\pkg{graphics} user-level commands robust]
+ {Make \pkg{color} \& \pkg{graphics} user-level commands robust}
+
+Some of the user-level commands of \pkg{color}, \pkg{graphics} and
+\pkg{graphicx} such as \cs{textcolor} or \cs{includegraphics} were
+still fragile, so didn't work in moving arguments without extra
+protection. All of them have now been made robust.
+%
+\githubissue{208}
+
+
+
+
+\section{Changes to packages in the \pkg{tools} category}
+
+\subsection{Fixed column depth in boxed \texttt{multicols}}
+
+The \texttt{multicols} environment was setting \cs{maxdepth} when
+splitting boxes but the way the internal interfaces of \LaTeX{} are
+designed it should have used \cs{@maxdepth} instead. As a result
+balanced boxed multicols sometimes ended up having different height
+even if they had exactly the same content.
+%
+\githubissue{190}
+
+
+\subsection{Ensure that \texttt{multicols} is not losing text}
+
+The \texttt{multicols} environment needs a set of consecutive boxes to
+collect column material. The way those got allocated could result in
+disaster if other packages allocated most boxes below box 255 (which
+\TeX{} always uses for the output page). In the original
+implementation that problem was identified because one could only
+allocate boxes below 255, but nowadays the \LaTeX{} allocation routine
+allows allocating boxes below and above 255. So the assumption that
+asking for, say 20 boxes you get a consecutive sequence of box
+registers was no longer true and so some of the column material could
+end in box 255 and be overwritten. This has now been corrected by
+allocating all necessary boxes above 255 if there aren't enough
+registers available.
+%
+\githubissue{237}
+
+\subsection{Allow spaces in \cs{hhline} arguments}
+
+The verb \verb|\hhline| command which allows
+specification of rule segments in \texttt{tabular} environments now
+allows (and ignores) spaces between its tokens so
+\verb|\hhline{: = : =}| is now allowed and equivalent to
+\verb|\hhline{:=:=}|. This matches similar token arguments in \LaTeX{}
+such as the \verb|[h t p]| argument on floats. A similar change has
+been made to the extended \verb|\hhline| command in the
+\texttt{colortbl} package.
+%
+\githubissue{242}
+
+
+
+\section{Primitive requirements}
+
+Since the finalization of \eTeX{} in 1999, a number of additional `utility'
+primitives have been added to \pdfTeX{}. Several of these are broadly useful
+and have been requirements for \pkg{expl3} for some time, most notably
+\cs{pdfstrcmp}. Over time, a common set of these `post-\eTeX{}' primitives have
+been incorporated into \XeTeX{} and (u)p-\TeX{}; they were available in
+\LuaTeX{} already.
+
+A number of the additional primitives are needed to support new or improved
+functionality in \LaTeX{}. This is seen for example in improved UTF-8 handling,
+which uses \cs{ifincsname}. The following primitive functionality (which in
+\LuaTeX{} may be achieved using Lua code) will therefore be \emph{required} by
+the \LaTeX{} kernel from the start of 2021:
+%
+\begingroup\setlength\columnsep{0pt}
+\begin{multicols}{2}
+\begin{itemize}
+ \item \cs{expanded}
+ \item \cs{ifincsname}
+ \item \cs{ifpdfprimitive}
+ \item \cs{pdfcreationdate}
+ \item \cs{pdfelapsedtime}
+ \item \cs{pdffiledump}
+ \item \cs{pdffilemoddate}
+ \item \cs{pdffilesize}
+ \item \cs{pdflastxpos}
+ \item \cs{pdflastypos}
+ \item \cs{pdfmdfivesum}
+ \item \cs{pdfnormaldeviate}
+ \item \cs{pdfpageheight}
+ \item \cs{pdfpagewidth}
+ \item \cs{pdfprimitive}

+ \item \cs{pdfsavepos}
+ \item \cs{pdfsetrandomseed}
+ \item \cs{pdfshellescape}
+ \item \cs{pdfstrcmp}
+ \item \cs{pdfuniformdeviate}
+\end{itemize}
+\end{multicols}
+\endgroup
+%
+For ease of reference, these primitives will be referred to
+as the `\pdfTeX{} utilities'. With the exception of \cs{expanded},
+these have been present in \pdfTeX{} since the release of version
+1.40.0 in 2007; \cs{expanded} was added for \TeX{}~Live
+2019. Similarly, the full set of utility primitives have been
+available in \XeTeX{} from the 2019 \TeX{}~Live release, and have
+always been available in \LuaTeX{} (some by Lua emulation). p\TeX{}
+and up\TeX{} gained all of the above bar \cs{ifincsname} for
+\TeX{}~Live 2019, and will have that primitive from the 2020 release.
+
+At the same time, engines which are fully Unicode-capable must all
+provide the following primitives
+%
+\begingroup\setlength\columnsep{0pt}
+\begin{multicols}{2}
+\begin{itemize}
+ \item \cs{Uchar}
+ \item \cs{Ucharcat}
+ \item \cs{Umathcode}
+\end{itemize}
+\end{multicols}
+\endgroup
+%
+Note that it has become standard practice to check for Unicode-aware
+engines with the existence of the \cs{Umathcode} primitive. As such,
+this is already a requirement: engines lacking these primitives cannot
+access Unicode features of the \LaTeXe{} kernel or of
+\pkg{expl3}. Note that up\TeX{} has facilities for handling Unicode
+but is not classed as a Unicode engine by the base LaTeX code.
