+@item Translators and contexts have been split. The result of this
+internal cleanup is that @code{Score} no longer is the top context;
+@code{Score} is contained in the @code{Global} context. Consequently,
+it is possible to tweak @code{Score} as follows:
+
+@example
+ \context Score \with @{
+ @dots{}
+ @}
+@end example
+
+@item The number of staff lines in Tablature notation is now
+automatically deduced from the @code{stringTunings} property.
+
+@item The program reference has been cleaned up and revised.
+
+@item The syntax for setting properties has been simplified:
+the following table lists the differences:
+
+@example
+ (old) (new)
+
+\property A.B = #C \set A.B = #C
+\property A.B \unset \unset A.B
+\property A.B \set #C = #D \override A.B #C = #D
+\property A.B \override #C = #D (removed)
+\property A.B \revert #C \revert A.B #C
+@end example
+
+Furthermore, if @code{A} is left out, the bottommost context is used
+by default. In other words, it is no longer necessary to explicitly
+mention @code{Voice}, @code{Lyrics} or @code{ChordNames}.
+
+Old:
+
+@example
+ \property Voice.autoBeaming = ##f
+ \property Staff.TimeSignature \set #'style = #'C
+@end example
+
+New:
+
+@example
+ \set autoBeaming = ##f
+ \override Staff.TimeSignature #'style = #'C
+@end example
+
+
+@item Tweaks made with @code{\override} and @code{\revert} no longer
+hide tweaks at higher context levels.

@item Melismata in lyrics are also properly handled in the MIDI output.
@item The lilypond-book script has been rewritten.
It is shorter, cleaner and faster. The special construct
@code{mbinclude} has been removed, plain @code{@@include} or
-@code{\\input} can be used now.
+@code{\input} can be used now.
@ignore
It now supports
@end example
@end ignore
-@item The @code{Lyrics} context has been removed. Lyrics should only
-be constructed in @code{LyricsVoice}.
+@item The @code{LyricsVoice} context has been removed. Lyrics should only
+be constructed in @code{Lyrics}.
@item The @code{Thread} context has been removed. Note heads and rests
are now constructed at @code{Voice} level.
