+\subsection{Add support for Unicode soft hyphens}
+
+For a long time, the UTF-8 option for \pkg{inputenc} made the Unicode
+soft hyphen character (U+00AD) an alias for the \LaTeX\ soft hyphen
+|\-|. The Unicode engines \XeTeX{} and \LuaTeX{} behaved
+different though: They either ignored U+00AD or interpreted it as an
+unconditional hyphen. This inconsistency is fixed now and \LaTeX{}
+always treats \texttt{U+00AD} as |\-|.
