+Version 2.1.9

+
+@itemize @bullet
+@item Formatting of ottava brackets has been much improved.
+
+@item Objects in the output can now be documented: the following fragment
+ boxes the note head, and adds the text ``heads or tails?'' three
+spaces below the box.
+
+@example
+ \context Voice \applyoutput #(add-balloon-text
+ 'NoteHead "heads, or tails?"
+ '(0 . -3))
+
+
+ c8
+@end example
+
+
+@item Default staff sizes are now scalable. There are two new mechanisms for
+setting staff sizes. Both are demonstrated in this fragment:
+
+@example
+ #(set-staff-size 15)
+ \paper @{
+ #(paper-set-staff-size (* 15 pt))
+ @}
+@end example
+
+
+@noindent
+Both have the same effect on the global layout of a
+piece. Similarly, the paper size may be changed as follows
+
+@example
+ #(set-paper-size "a4")
+@end example
+
+
+@item Warnings for bar check errors are more cleverly printed. This
+makes @code{barCheckSynchronize} superfluous, so it is now switched
+off by default.
+
+Warning: this will cause problems in scores that use bar checks to
+shorten measures.
+
+@item The black note head was made a little rounder, which causes a less
+ frantic graphic impression.
+
+@item
+A more concise syntax for checking octaves was introduced. A note may
+be followed by @code{=}@var{quotes} which indicates what its absolute
+octave should be. In the following example,
+
+@example
+ \relative c'' @{ c='' b=' d,='' @}
+@end example
+
+@noindent
+the @code{d} will generate a warning, because a @code{d''} is
+expected, but a @code{d'} is found.
+
+@item There is a new mechanism for putting lyrics to melodies.
+With this mechanism, @code{LyricVoice}s can be put melodies
+individually, allowing for different melismatic sections in every
+@code{LyricVoice}. See @file{input/regression/lyric-combine-new.ly}.
+
+@item Bar lines may now be dotted.
+
+
+@item The documentation now has links to a wiki, where everyone can
+add personal comments to the manual.
+
+@item Contexts may now be changed locally for an isolated music
+expression. For example,
+
+@example
+ \new Voice \with @{
+ \consists "Pitch_squash_engraver"
+ @} @{
+ c'4
+ @}
+@end example
+
+@item The syntax for changing staffs has changed. The keyword
+@code{\change} should now be used, e.g.
+
+@example
+ \change Staff = up
+@end example
+
+@item Features of spanner contexts, like @code{Staff}, can now be changed
+ using @code{\property}, eg.
+
+@example
+ \new Staff @{
+ \property Staff.StaffSymbol \set #'line-count = #4
+ c'4
+ @}
+@end example
+
+@noindent
+puts a quarter note C on a staff with 4 lines.
+
+
+@item Multi measure rests are now truly centered between the
+clefs/barlines of the staff, their position is independent of symbols
+on the other staffs.
+
+@item Collision resolution for dots in chords has been improved greatly.
+
@item
Spacing following barlines was improved for widely stretched lines.
@item
-Lyric hyphens now conform to standard typesetting practice.
+Lyric hyphens and extenders now conform to standard typesetting
+practice.
@item
-Lyrics are now aligned under note heads conforming engraving
+Lyrics are now aligned under note heads conforming to engraving
standards. The responsible code has been rewritten, and is drastically
simpler from the previous version. To aid this rewrite, the syntactic
-function of the extender line ( __ ) is been changed: it is now attached
-to the lyric syllable.

When redefining a context, the associated identifier is also
-updated. For example, after reading following the snippet,
