Decimal numbers can now be written directly in music,
without a hash sign. Together with the previous change
rehearsal marks are aligned:
@lilypond[verbatim,quote,relative=1]
-% The rehearsal mark will be aligned to right edge of the Clef
+% The rehearsal mark will be aligned to the right edge of the Clef
\override Score.RehearsalMark.break-align-symbols = #'(clef)
\key a \major
\clef treble
\mark "↓"
e1
-% The rehearsal mark will be centered above the Time Signature
+% The rehearsal mark will be aligned to the left edge of the Time Signature
\override Score.RehearsalMark.break-align-symbols = #'(time-signature)
\key a \major
\clef treble
