+There is now a new context type called @code{NullVoice} which, while not
+appearing in the printed output, can be used to align lyrics. This can
+be particularly convenient when used in parallel with a
+@code{\partcombine} construct.

+@lilypond[verbatim,quote]
+soprano = \relative c' { c e g c }
+alto = \relative c' { a c e g }
+verse = \lyricmode { This is my song }

+The baseline of score markups is now taken from the reference
+point (usually the middle of the staff) of the first bottom system
+rather than the top of the bounding rectangle. The following

+LilyPond no longer automatically infers a @samp{\defaultchild}
+context in a context definition with @samp{\accepts} clauses. Any
+context definition without an explicit or inherited
+@samp{\defaultchild} definition counts as a @samp{Bottom} context
+and will be eligible for rhythmic events and overrides without
+causing the implicit creation of other contexts. Be sure to
+specify a @samp{\defaultchild} for non-@samp{Bottom} contexts when
+defining them from scratch.

+There is now extensive support for both discant and bass accordion

Decimal numbers can now be written directly in music,
without a hash sign. Together with the previous change
