+Scheme expressions inside of embedded Lilypond (@code{#@{@dots{}#@}})
+are now executed in lexical closure of the surrounding Scheme code.
+@code{$} is no longer special in embedded Lilypond.  It can be used
+unconditionally in Lilypond code for immediate evaluation, similar to
+how @code{ly:export} could previously be used.  @code{ly:export} has
+been removed.  As a consequence, @code{#} is now free to delay
+evaluation of its argument until the parser actually reduces the
+containing expression, greatly reducing the potential for premature
+evaluation.

+Support for jazz-like chords has been improved: Lydian and altered
+chords are recognised; separators between chord modifiers are now
+treated independently of separators between ``slash'' chords and their
+bass notes (and by default, slashes are now only used for the latter
+type of separator); additional pitches are no longer prefixed with
+``add'' by default; and the ``m'' in minor chords can be customized.
+@ruser{Customizing chord names} for more information.

 The @code{\markuplines} command has been renamed to @code{\markuplist}
