\section{New or improved commands}
+\subsection{\cs{NewCommandCopy} and \cs{ShowCommand} extended}
+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.

+In that same release, the \pkg{xparse} package was integrated

+\LaTeX{} release implements this support, so now commands
+defined with \cs{NewDocumentCommand} and friends can also be copied, and their definitions
+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})
+once it
+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 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 default value for \cs{tracinglostchars}}
+
+In 2021 all \TeX{} engines were enhanced so that \cs{tracinglostchars}
+supported the value \texttt{3} to turn missing
+characters into errors and not just warnings.
+%
+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 be ideal, 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).
