+Decimal numbers can now be written directly in music,
+without a hash sign.  Together with the previous change
+in the way object properties are specified, the code to
+change the length of stems has changed from this:
+@example
+\override Stem #'length = #5.6
+e' f' g' a'
+@end example
+to this:
+@example
+\override Stem.length = 5.6
+e' f' g' a'
+@end example
+
+One has to write a digit on both sides of the dot -- values like
+@code{4.} or @code{-.3} are not allowed.
+
+Decimal fractions are also not accepted in @code{\chordmode}.
+
+@item
+A number of shorthands like @code{(}, @code{)}, @code{|},
+@code{[}, @code{]}, @code{~}, @code{\(}, @code{\)} and others can
+now freely be redefined like normal commands.  An example would be
+@lilypond[verbatim,quote]
+"\\{" = (
+"\\}" = )
+"(" = \melisma
+")" = \melismaEnd
+
+\new Staff <<
+  \relative c' {
+    c8 \{ d e f \} % slurred
+    g ( a b c ) % no slur, but with melisma
+    c,1 \bar "|."
+   }
+   \addlyrics { Li -- ly -- pond. }
