LilyPond 2.1.19 is out

[Han-Wen Nienhuys]

LilyPond 2.1.19 cleans up a bunch long-standing warts: I've removed
Thread context, and Lyrics context (the function of both is taken by
Voice and LyricsVoice respectively). This cleanup was enabled by a
rewrite of the drum notation support, which is now properly done.


NEWS:

   * The `Lyrics' context has been removed. Lyrics should only be
     constructed in `LyricsVoice'.

   * The `Thread' context has been removed. Note heads and rests are
     now constructed at `Voice' level.

   * Harmonic notes can now be entered as
             <c' g''\harmonic>

   * Drum notation is now supported  as a regular feature: percussion
     may be entered in `\drums' mode, and printed in a `DrumStaff'
     context:

            \score {
              \drums \new DrumStaff { hihat4 cowbell8 }
            }
