LilyPond 2.1.20 is out

The biggie in .20 is the new lilypond-book script, which was fruit of
Jan's  work of the past week. It is simpler and quicker the moloch
that we used to have. Other attractions are: MIDI output for drums,
melisma support for MIDI lyrics and a lot of bugfixes.


NEWS

   * Melismata in lyrics are also properly handled  in the MIDI output.

   * The lilypond-book script has been rewritten.  It is shorter,
     cleaner and faster.  The special construct `mbinclude' has been
     removed, plain `@include' or `\\input' can be used now.
