Hi,
I have a few problems with Lilypond 1.1.56.
1. Key signatures are no longer transposed with the rest of
the music.
\notes\transpose bes {\key D; d1 }
should produce no key signature (key C)
2. Crescendos and other dynamic markings that start inside a
\grace { } section are ignored.
\notes \relative c' { fis4 r4 \grace { [g16 ( \< a16] }
) b4 \! a8. g16}
3. Slurs that end within a grace section but start outside
are treated strangely.
a2 d,4 ( \grace { [e16 ) d16]} cis8 d
4. Lyrics and grace sections don't go too well together.
The words are aligned with the main note, not the start of the
grace note. This is usually wrong, but is sometimes right.
