+@unnumbered New features in 2.1 since 2.0
-@ignore
-Unreleased:
+@itemize @bullet
-@itemize
-@end itemize
+@item The @code{Timing_engraver} now sets the @code{Timing} alias on
+its containing context automatically.
-Version 2.1.13
-@end ignore
+@item The code for font selection has been rewritten. In addition to
+existing font selection properties, the property @code{font-encoding}
+has been added, which makes the switch between normal @code{text} and
+other encodings like @code{braces}, @code{music} and @code{math}.
-@itemize @bullet
+@item The pmx2ly script has been removed from the distribution.
+
+@item Pedal brackets will now run to the last bar of a piece if they are not
+explicitly ended.
-@item Drum notation is now supported natively:
-percussion may be entered in @code{\drums} mode, and printed in a
-@code{DrumStaff} context:
+@item Context definitions now use the word @code{\context} instead of @code{\translator}.
+
+@item Property functions may be used as an argument to @code{set!},
+for example
+
+@example
+ (set! (ly:grob-property grob 'beam) ... )
+@end example
+
+@item In anticipation of Emacs 21.4 or 22.1, the info documentation contains
+images.
+
+@item Cue notes can be quoted directly from the parts that
+contain them. This will take into account transposition of source and target
+instrument. For example,
+
+@verbatim
+\addquote clarinet \notes\relative c' {
+ \transposition bes
+ fis4 fis fis fis
+}
+
+\score {
+ \notes \relative c'' {
+ c8 d8 \quote 2 oboe es8 gis
+ }
+}
+@end verbatim
+
+@item The transposition of an instrument can be specified using the
+@code{\transposition} command. An
+E-flat alto saxophone is specified as
+
+@example
+ \transposition es'
+@end example
+
+@item The naming of exported Scheme functions now follows Scheme conventions.
+Changes be applied to Scheme files with
+
+@example
+ convert-ly -e -n --from=2.1.24 --to=2.1.26 *.scm
+@end example
+
+
+@item Notes can be excluded from auto-beaming, by marking them with
+@code{\noBeam}
+@example
+ c8 c \noBeam c c
+@end example
+
+@noindent
+will print two separate eighth notes, and two beamed notes.
+
+@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.
+
+It now supports running convert-ly on the lilypond snippets,
+@example
+ lilypond-book --filter='convert-ly --from=2.0.0' my-book.tely
+@end example
+
+@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.
+
+@item Harmonic notes can now be entered as
+
+@example
+ <c' g''\harmonic>
+@end example
+
+@item Drum notation is now supported as a regular feature:
+percussion may be entered in @code{\drums} mode, and printed or
+performed in a @code{DrumStaff} context:
@example
\score @{
@}
@end example
-
@item The automatic staff changer was internally rewritten. As a
result, the syntax has been simplified as well:
@example
- \autochange @var{the music}
+ \autochange @var{the-music}
@end example
@item The ergonomic syntax of @code{\markup} now has an equivalent in
@noindent
-Both have the same effect on the global layout of a
-piece. Similarly, the paper size may be changed as follows
+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")
+ #(set-default-paper-size "a4")
+ \paper @{
+ #(set-paper-size "a4")
+ @}
@end example
@noindent
the d will generate a warning, because a d'' is
expected, but a d' is found.
-@c @code adds ` ' very confusing.
+@c @code adds ` ', very confusing.
@item There is a new mechanism for putting lyrics to melodies.
-With this mechanism, @code{LyricVoice}s can be put melodies
+With this mechanism, @code{Lyrics} lines 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.
@end example
@item Features of spanner contexts, like @code{Staff}, can now be changed
- using @code{\property}, eg.
+ using @code{\set}, eg.
@example
\new Staff @{
- \property Staff.StaffSymbol \set #'line-count = #4
+ \override Staff.StaffSymbol #'line-count = #4
