+\subsection{Fix the use of  \texttt{localmathalpabets}}
+
+In 2021 we introduced a method to overcome the problem that classic
+\TeX{} engines (but not the Unicode engines) have only a limited
+number of math alphabets available that got easily fill up simply by
+loading math font packages, even if their symbols got used only
+occasionally. The idea was to avoid allocating all math alphabets
+globally, but instead allow a number of them (defined by counter
+\texttt{localmathalpabets}) to vary from one formula to the next. This
+way different formulas can make use of different alphabets and chances
+are much higher that the processing a complex the document succeeds.
+See~\cite{41:ltnews34} for details.
+
+Unfortunately, the approach taken failed in some cases of nested
+formulas with the result that the wrong symbol glyphs were used
+(rather than, as before, your \LaTeX{} run stopped with a fatal error
+message). This has now been corrected.
