+\maketitle
+
+This file lists functions whose syntax has changed after August 2011,
+with an approximate date.
+
+\section{August 2011}
+
+\begin{itemize}
+  \item \cs{tl_if_single:n\TF} recognized any non-zero number of
+    explicit spaces as \meta{true}, and did not ignore trailing spaces.
+    Now it is \meta{true} for
+    \[
+      \meta{optional spaces}
+      \meta{normal token or brace group}
+      \meta{optional spaces}.
+    \]
+  \item \cs{tl_reverse:n} stripped outer braces and lost unprotected spaces.
+    Now it keeps spaces, leaves unbraced single tokens unbraced, and
+    braced groups braced.
+  \item \cs{tl_trim_spaces:n} only removed one leading and trailing space.
+    Now removes recursively. Also, on the left it used to strip implicit
+    and explicit spaces with any character code. Now it strips only explicit
+    space characters $(32,10)$.
+\end{itemize}
+
+\section{September 2011}
+
+\begin{itemize}
+\item clist functions which receive an \texttt{n}-type comma list argument
+  now trim spaces from each item in the argument.
+\end{itemize}
+
+\section{June 2012}
+
+\begin{itemize}
+  \item Access to list functions now indexes from~$1$, not from~$0$.
+  This applies to multiple choices in the \pkg{l3keys} module and
+  the \cs{clist_item:Nn}, \cs{seq_item:Nn} and \cs{tl_item:Nn}
+  functions.
+  \item \cs{tl_trim_spaces:n} now requires a variable number of
+  expansions to fully expand, rather than exactly two.  Of course,
+  \texttt{x}-type expansion still correctly evaluates this function.
+\end{itemize}
+
+\section{July 2012}
+
+\begin{itemize}
+  \item The \cs{tl_if_head_eq_meaning:nN}, \cs{tl_if_head_eq_catcode:nN}
+    and \cs{tl_if_head_eq_charcode:nN} conditionals now never match when
+    their first argument is empty.
+\end{itemize}
+
+\section{August 2012}
+
+\begin{itemize}
+  \item \cs{lua_now:x} is now a standard \texttt{x}-type expansion of
+    \cs{lua_now:n}, which does no expansion. Engine-level expansion is moved
+    to \cs{lua_now_x:n}, reflecting the fact that this is non-standard in the
+    same way as for example \cs{str_if_eq_x:nn(TF)}.
+\end{itemize}
