-to provide some information that is only written to the \texttt{.log}

+\LaTeX{} offers these three commands:\cs{PackageError} to signal errors that

-\subsection{New default for \cs{tracinglostchars}}
+We have therefore now added \cs{PackageNote} (and the closely
+related \cs{PackageNoteNoLine}): these identify
+themselves as \enquote{informational}, but they still go to the terminal and
+not only to the \texttt{.log} file.
+%
+Similar commands exist for classes and so there too we have
+new commands: \cs{ClassNote} and \cs{ClassNoteNoLine}.
+%
+\githubissue{613}
-In 2021 the \TeX{} engines got enhanced so that \cs{tracinglostchars}
-is now also supporting the value \texttt{3}, turning missing
-characters into errors and not just warnings. This change made us
-realize that \LaTeX{} should use a better default for this parameter
-(so far the warning was only written to the transcript file).
-Using the now available \texttt{3} would really be the best, but for
-compatibility reasons we only set it to \texttt{2} in the kernel.
-However, we recommend adding \cs{tracinglostchars}\texttt{=3} to the
-preamble of documents, because missing glyphs in the output are an
-error and should therefore be properly looked at.
+\subsection{New \cs{ShowFloat} command}
+The package \pkg{fltrace} offers a (fairly low-level but very
+detailed) way to trace \LaTeX's float mechanism. This can help in

+\subsection{\cs{NewCommandCopy}, \cs{ShowCommand} now in \pkg{ltcmd}}
+Since the 2020-10-01 release (see~\cite{34:ltnews32}), \LaTeX{}
+has provided \cs{NewCommandCopy} to copy robust commands,
+and \cs{ShowCommand} to show their definitions on the terminal.

+\LaTeX{} release implements this support, so now commands

+can be easily shown on the terminal without the need for ``\cs{csname} gymnastics''.
+%
+\githubissue{569}
+\subsection{Undo math alphabet allocations if necessary}
+\TeX{}, or more exactly the 8-bit versions of \TeX, such as \pdfTeX{}
+have a hard limit of 16 on the number of different math font groups
+(\cs{fam} or \cs{mathgroup}) that can be used in a single formula. For each symbol font
+declared (by a package or in the preamble) an extra math group is allocated,
+and the same happens for each math alphabet, (such as \cs{mathbf}) that
+gets used anywhere in the document. Up to now, these math
+alphabet allocations were permanent, even if they were
+used only once;
+the result was that in complex documents you
+could easily run out of available math font groups.
+The only remedy for this was to
+define your own math version, which is a complicated and cumbersome process.
+This situation has now been improved by the introduction of a new counter
+\texttt{localmathalphabets}: this counter governs how many of
+the math group slots are assigned only locally when a new math
+alphabet (and a new math group) is needed.
+%
+Once the current formula is finished, every such further (local)
+allocation is undone, giving you a fighting chance of being
+able to use different new math alphabets in the next formula.
+The default value of \texttt{localmathalphabets} is 2,
+but if you need more local alphabets because of the complexity of your
+document, you can set this to a higher value such as 4 or 5.
+Setting it even higher is possible, but this would seldom
+be useful because many group slots will be taken up by
+symbol fonts and such slots are always permanently allocated,
+whether used or not.
+%
+\githubissue{676}
-\subsection{New \cs{ShowFloat} command}
-The package \pkg{fltrace} offers a (fairly low-level but very
-detailed) way to trace \LaTeX's float mechanism. This can help to
-understand why a certain float is placed into a certain region or why
-it shows up unexpectedly on a later page. \LaTeX{} stores floats in
-registers named \cs{bx at A}, \cs{bx at B}, etc., and these names show up in
-the tracing information.
+\subsection{Better handling for a misuse of \cs{include}}
+
+The command \cs{include} is by now getting used quite often, but
+erroneously, to input a variety files in the preamble of the document
+(before \verb|\begin{document}|).
%
-To display their contents you can now say
-\verb=\ShowFloat{=\textit{identifier}\verb=}= where
-\textit{identifier} is the uppercase letter (or letters) after
-\texttt{bx@} in the register name shown in the tracing. If additional
-registers have been allocated with \cs{extrafloats}, the
-\textit{identifier} can also be a number. The command is generally
-available, whether or not you have loaded \pkg{fltrace}, because it is
-also useful when interpreting the tracing output of the
-\pkg{fewerfloatpages} package.
+Therefore \LaTeX\ now warns about such bad use of \cs{include}.
+As a recovery action it will nevertheless input the specified file
+if it exists (this is as before). Note, however, that this is now done
+without any adjustments to the \texttt{.aux} file settings and
+without running the \cs{include} file hooks (only the generic
+file hooks from \cs{InputIfFileExists} are run).

-\subsection{Add \pkg{ltcmd} support for \cs{NewCommandCopy} and \cs{ShowCommand}}
+\subsection{New default value for \cs{tracinglostchars}}
-Since the 2020-10-01 release (see~\cite{34:ltnews32}), \LaTeX{} provides
-\cs{NewCommandCopy} to copy robust commands, and \cs{ShowCommand} to
-show their definition in the terminal. In the same release, the
-\pkg{xparse} package was integrated in the kernel (now called
-\pkg{ltcmd}). However, the extended support for \cs{NewCommandCopy} and
-\cs{ShowCommand} was not implemented in \pkg{ltcmd}. The present
-\LaTeX{} release ships with that support implemented, so now commands
-defined with \pkg{xparse}/\pkg{ltcmd} can be copied and their definition
-can be easily shown in the terminal without \cs{csname} gymnastics.
+In 2021 all \TeX{} engines were enhanced so that \cs{tracinglostchars}
+supported the extra value \texttt{3}, that turns missing
+characters into errors and not just warnings.
%
-\githubissue{569}
+This engine change made us
+realize that \LaTeX{} should set a better default value for this parameter
+(previously, the warning was written only to the transcript file).
+Using the now available value of \texttt{3} as the default
+would really be best, but for
+compatibility reasons we have only increased it to \texttt{2} in the kernel.
+%
+However, we recommend setting \cs{tracinglostchars}\texttt{=3},
+in either a package or the
+preamble of your documents: this is because having missing glyphs
+in the output is definitely an error and should therefore be
+flagged as such (to ensure that it gets proper attention).
+Further reasons, related especially to Unicode engines, for making
+this recommended change can be found later in this newsletter
+(in connection with the misuse of text accents in mathmode).

+Since 2020, as noted in \LaTeX News 32~\cite{34:ltnews32}, \LaTeX\ has

+prefixes such as \enquote{Figure} before the reference text.

+In the most
+common cases the current label is set by \cs{refstepcounter}, which
+automatically stores the counter name; but some constructs (alignments
+and footnotes) may need to store the current label directly and so for
+these it is useful to update additionally \cs{@currentcounter} so as to
+store this counter name.
+In this release both the footnote command in the kernel and
+also some of the environments in the \pkg{amsmath} package
+have been updated in this way.

+Using text accents like \verb|\^| in math does not work

-\githubissue{000}
+This has now been changed so that the message from this
+error is at least about accents, which we hope is less puzzling.
+Discussion of such warnings or errors reminds us to reinforce
+here a recommendation from earlier in this newsletter, as part
+of the item on the value of \cs{tracinglostchars}.
+%
+Using \TeX\ implementations from 2020 onwards, any warning that
+concerns missing characters can be

+% {Correct patching by expansion+redefinition when the macro
+% contains a parameter tokens (gh/697).}
+% Patching with expansion+redefinition is trickier than it looks like
+% at first glance. Suppose the simple definition:
+% \begin{verbatim}
+% \def\foo#1{#1##2}
+% \end{verbatim}
+% When defined, its \meta{replacement text} will be a token list
+% containing:
+% \begin{quote}
+% \itshape
+% out\_param |1|, mac\_param |#|, character |2|
+% \end{quote}
+%
+% Then, after expanding \cs{foo}|{##1}| (here |##| denotes a single
+% |#|$_6$) we end up with a token list with \textit{out\_param}~|1|
+% replaced:
+% \begin{quote}
+% \itshape
+% mac\_param |#|, character |1|, mac\_param |#|, character |2|
+% \end{quote}
+% that is, the definition would be:
+% \begin{verbatim}
+% \def\foo#1{#1#2}
+% \end{verbatim}
+% which obviously fails, because the original input in the definition
+% was |##| but \TeX{} reduced that to a single parameter token |#|$_6$
+% when carrying out the definition. That leaves no room for a clever
+% solution with (say) \cs{unexpanded}, because anything that would
+% double the second |#|$_6$, would also (incorrectly) double the
+% first, so there's not much to do other than a manual solution.
+%
+% There are three cases we can distinguish to make things hopefully
+% faster on simpler cases:
+% \begin{enumerate}
+% \item a macro with no parameters;
+% \item a macro with no parameter tokens in its definition;
+% \item a macro with parameters \emph{and} parameter tokens.
+% \end{enumerate}
+%
+% The first case is trivial: if the macro has no parameters, we can
+% just use \cs{unexpanded} around it, and if there is a parameter
+% token in it, it is handled correctly (the macro can be treated as a
+% |tl| variable).
+%
+% The second case requires looking at the \meta{replacement text} of
+% the macro to see if it has a parameter token in there. If it does
+% not, then there is no worry, and the macro can be redefined normally
+% (without \cs{unexpanded}).
+%
+% The third case, as usual, is the devious one. Here we'll have to
+% loop through the definition token by token, and double every
+% parameter token, so that this case can be handled like the previous
+% one.

+%
+% The use of \cs{c_@@_hash_tl} here is to differentiate actual
+% parameters in the macro from parameter tokens in the original

+% (then \cs{@@_exp_not:n} is \cs{exp_not:n}), call

+% keep a defined number of math alphabets flexible/local. If we have to
+% allocate any of those we roll back the allocation after the
+% formula has ended, so the next formula can use other alphabets in
