+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}
