release: 1.3.78

===========

* Added a devnull engraver, that junks (notehead) requests of the second
  stem when combined parts are in unison (a2).

* Part-combine iterator identifies Soli and A2 parts in threads by
  looking at rhythm and pitches.  It switches Voice context automagically,
  and communicates current state using a2/solo/solo2 properties.

* Simple A2_engraver (`a due) prints `a2/Solo/Solo II.  Soli seem to
  arrive one request late.

* First try at combining parts: part-combine*

* fixed problem with HaraKiri

* fixed problem with dynamicDirection

* fixed problem with nonEmptyText

* `Fixed' chord notation, as per request of David Arnold, ie,
   Added a chord-name-mode, that only displays chord names
   when there's a change in the chord-name-scheme, Also, a chord
   name should always be displayed after a line break.  See

       input/test/drarn-chords.ly

* Reverted duration-iter change in midi2ly, moved printing of options.

* warning bugfix in lexer.ll (Mats Bengtsson)
