When Han-Wen asked us to report bugs, I tried out a number features
that haven't worked before and was happy to find that most of them
had been solved. Congratulations on a great job, Han-Wen and Jan.
However, if you don't find old bugs, you can always find new ones:
Crescendi/diminuendi that cross a line break lose their vertical
position and all end up above the top staff line, see the
following example.
----------------
\score{
\context StaffGroup <
\context Staff=s1 \notes\relative c'{
c d e f |
g f e d | \break %% If this break is removed, it works fine
c d e f |}
\context Staff=s2 \notes\relative c'{
c \< d e f |
g f e d |
c d e \! f |}
>
}
