+Rehearsal marks at the beginning of a line are now placed to the right
+of the clef and key signature by default. As in previous versions, the
+@code{break-alignable-interface} controls the behavior.

+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}.

+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]
+"\\{" = (
