-\section{Avoid code duplication in rollback}
-
-When the kernel uses \cs{AddToHook} in a region that might be 
-rolled back (which happens in a few places) and a document requests a
-rollback, then we have the situation that the hook already contains code to which we added the same
-(or slightly different) code during the
-rollback; this results in code duplication or, worse, in errors. This has
-now been corrected by dropping any such code chunk (if there is one) prior to
-adding the rollback code.
+\section{Passing template keys using \cs{KeyValue}}
+
+With the move of the template code to the kernel, some internal efficiencies
+were also made. However, there was an oversight in how passing key values from
+one setting to another was implemented, meaning that using \cs{KeyValue} could
+result in an infinite loop. This has now been fixed.

+\subsection{Handling of global keys with spaces}
+
+If the global (class) options contained spaces around key names,
+\cs{ProcessKeyOptions} would fail to remove known keys from the
+list of unused global options and \cs{OptionNotUsed} would mistakenly
+add space-surrounded key names to that list.
+These has been corrected as a hotfix in patch level 1 of the November 2023
+release (but unfortunately not mentioned in~\cite{40:ltnews38}) and
+the current release, respectively.
