@item
-auotbeaming is now disabled by @code{\cadenzaOn} and enabled by
-@code{\cadenzaOff}. Beaming in cadenzas should be indicated manually.
-Also, if a cadenza is used in a piece with autobeaming disabled, it
-will need to be disabled again after the cadenza.
-
-@item
-The user is now able to specify the name of the predefined fretboard
-table. This allows the use of multiple tables, with switching between them
-based on user input.
+Grob @code{OctavateEight} was renamed to @code{ClefModifier}.
+Related context properties were renamed from @code{xxxOctavationyyy}
+to @code{xxxTranspositionyyy}.
@item
-The part-combiner's decision to combine/not combine notes can now be customized
-@lilypond[quote,relative=2]
-\partcombine
-\relative c' { c2 \partcombineApart c | \partcombineChordsOnce e' e }
-\relative c' { c2 \partcombineApart c | c c }
+There is a new @code{\absolute} command explicitly marking music
+as being entered in absolute pitch. While this has been the
+default previously, an explicit @code{\absolute} also prevents
+reinterpretation when the passage is placed inside of
+@code{\relative}:
+@lilypond[verbatim,quote]
+\relative c { c'4 \absolute { f'' g'' } c }
@end lilypond
@item
-Tablature staves show fret numbers only by default. To get the
-former style, @code{\tabFullNotation} is provided.
+When @code{\relative} is used without an explicit reference pitch,
+the reference pitch now is the middle of the first octave, making
+the first entered pitch indistinguishable from absolute pitch.
+Previously, omitting the reference pitch would have lead to a
+default of @code{c'}. Since that choice was somewhat arbitrary,
+recommended usage was to always specify the reference pitch.
@item
-Funk-style and Walker-style shape notes have been added.
+A new command @code{\single} can be used for converting a property
+override into a tweak to be applied on a single music expression:
-@item
-Rests will no longer keep a staff alive if @code{\RemoveEmptyStaffContext}
-is used.
+@lilypond[quote,verbatim,relative=2]
+<a \single\voiceTwoStyle e' a>1
+@end lilypond
@item
-New option @code{-dinclude-settings=INCLUDEFILE.ly}, which causes lilypond
-to include the given file before the score is processed. This allows the
-user to change global settings without the need to change the score itself.
-That way, several different editions/version (e.g. different page sizes)
-can be generated from a file without having to modify the score for each
-version.
+Two ways of letting graphical objects not appear in the output are
+overriding its @code{transparent} property with @code{#t}
+(retaining the original spacing) or overriding its @code{stencil}
+property with @code{#f} (not using any space at all). Those two
+operations now have the shorthands @code{\hide} and @code{\omit},
+respectively. They can either be given a music expression to
+tweak, or the name of a graphical object for which an override
+should be created (for specifying both, use @code{\single} on the
+override form):
-@item
-The autobeaming settings syntax has been changed. beatLength,
-beatGrouping, beamSettings, and measureGrouping have all been eliminated.
-Autobeaming is now controlled by baseMoment, beatStructure, and
-beamExceptions. Default settings for each of these properties can be
-stored for any time signature in time-signature-settings, so that
-when the time signature is changed, the autobeaming will automatically
-change. The new syntax should be much easier and require fewer
-overrides.
+@lilypond[quote,verbatim]
+\new Staff \with { \omit Clef }
+\relative c'' <a e' \hide a>1
+@end lilypond
@item
-The SVG backend has optional support for
-@uref{http://www.w3.org/Submission/WOFF, WOFF fonts}. Using the Scheme
-option @code{-d svg-woff} together with the SVG backend selection
-@code{-d backend=svg}, produces SVG output with CSS WOFF font selection.
+A new command @code{\temporary} can be applied to overrides in
+order to not have them replace previous property settings. If a
+@code{\revert} is applied to the same property subsequently, the
+previous setting reappears:
-@item
-The LilyPond G clef has been rotated 1.5 degrees clockwise for improved
-balance. The old and new versions can be compared by looking at the
-documentation:
-@uref{http://lilypond.org/doc/v2.12/Documentation/user/lilypond/The-Feta-font.html#Clef-glyphs,
-old version},
-@uref{http://lilypond.org/doc/v2.13/Documentation/notation/the-feta-font.html#Clef-glyphs,
-new version}.
+@lilypond[quote,verbatim,relative=2]
+\override NoteHead.color = #red c4
+\override NoteHead.color = #green d
+\revert NoteHead.color e2
+\override NoteHead.color = #red c4
+\temporary\override NoteHead.color = #green d
+\revert NoteHead.color e
+\revert NoteHead.color c
+@end lilypond
+This is mainly useful for writing music functions that need to
+have some property changed just for the duration of the function.
@item
-Text crescendo spanners can now be added directly using @code{\cresc},
-@code{\dim} and @code{\decresc}.
-@lilypond[quote,relative=2]
-c4\cresc c c c\f |
-c4\dim c c c\!
-@end lilypond
+@code{\tag}, @code{\removeWithTag}, and @code{\keepWithTag} can
+now accept a list of symbols rather than just a single symbol for
+marking, removing, and keeping music with any of multiple tags.
+This is particularly important for @code{\keepWithTag} since one
+cannot achieve the same effect by using multiple consecutive
+@code{\keepWithTag} commands.
+@item
+The @samp{-d old-relative} option has been removed. Not actually
+accessible from the command line any more, its remaining use was
+for interpretating @code{\relative} in LilyPond files converted
+automatically from version@tie{}1.8 or older. It is unclear how
+much of this was actually still operative.
@item
-The documented syntax of @samp{lilypond} environments in the @LaTeX{}
-mode of @command{lilypond-book} has been changed to conform with
-standard @LaTeX{} syntax: options now come after the environment name:
+The meaning of @code{instrumentTransposition} has been reversed.
+After
@example
-\begin@{lilypond@}[@var{options}] @dots{}
+\set instrumentTransposition = #@{ b #@}
@end example
+a written @code{c'} now sounds like @code{b}. Previously, this
+would have been the other way round. This and the following change
+should make dealing with transposing instruments more
+straightforward.
-The previous syntax with options after @samp{\begin} is still accepted
-by @command{lilypond-book} but deprecated. Something like
+@item
+The music generated by @code{\set} and @code{\override} commands
+is no longer affected by @code{\transpose}. The main consequence
+is that @code{\transpose} will transpose audible/@/concert pitch and
+printed pitch by the same amount even when the transposed music
+contains @code{\transposition}. Previously,
@example
-sed -i '/begin\[/s/begin\(\[[^]]*]\)\(@{lilypond@}\)/begin\2\1/'
+\transpose c' f' \transposition bes'
@end example
-
-might do the trick for conversion.
+was equivalent to @code{\transposition f'}. Now it stays
+equivalent to @code{\transposition bes'}.
@item
-Aesthetics of shape note heads have been enhanced. Variable line thicknesses
-have been implemented. All note widths have been made consistent.
-Minor shape note commands that use the relative major key for scale steps
-have been added.
+When checking for collisions, LilyPond no longer treats objects as
+rectangles. Instead, the actual shape of objects is approximated
+using an integral-like approach. This generally results in more
+even and snug positioning of objects and systems:
-@item
-A variant of the segno sign is provided:
-@lilypond[quote,relative=2]
-c4 d e f \bar "S"
-g4 f e d
+@lilypond[relative=1]
+#(ly:set-option 'debug-skylines #t)
+\dynamicUp
+c'4\f a4\f d\f( f)
+a,4\< c c c\!
+d4-.\downbow a4^"r'venu..." c \tempo "T1" e
@end lilypond
-@item
-Context modifications (@code{\with} blocks) can be stored in variables and
-inserted into contexts or other @code{\with} blocks:
-@lilypond[quote,verbatim]
-coloredheads = \with { \override NoteHead #'color = #red }
-noclef = \with { \remove "Clef_engraver" }
-\score {
- \new Staff {
- \new Voice \with { \coloredheads } \relative c' { c4 e g c }
- }
- \layout {
- \context {
- \Staff
- \noclef
- }
- }
-}
+Previously, the above snippet looked like this:
+
+@lilypond[relative=1]
+#(ly:set-option 'debug-skylines #t)
+\override Hairpin #'vertical-skylines = #'()
+\override DynamicText #'vertical-skylines = #'()
+\override TextScript #'vertical-skylines = #'()
+\override Score.MetronomeMark #'vertical-skylines = #'()
+\override Staff.Clef #'vertical-skylines = #'()
+\dynamicUp
+c'4\f a4\f d\f( f)
+a,4\< c c c\!
+d4-.\downbow a4^"r'venu..." c \tempo "T1" e
@end lilypond
-@item
-A half-open articulation was added:
-@lilypond[quote,relative=2]
-c4\halfopen
+Affected objects include @code{Accidentals}, @code{Beams}, @code{Clefs},
+@code{Dynamics}, @code{FiguredBass}, @code{Flags}, @code{Glissandos},
+@code{Lyrics}, @code{MetronomeMarks}, @code{OttavaBrackets},
+@code{Pedals}, @code{RehearsalMarks}, @code{Rests}, @code{Scripts},
+@code{TextScripts}, @code{Ties}, @code{Tuplets} and @code{VoltaBrackets}.
+
+@item
+Tuplets are now created with the @code{\tuplet} command, which
+takes a fraction @code{@var{t}/@var{n}} to specify that @var{t}
+notes are played in the time usually allowed for @var{n}. One
+@code{\tuplet} command can create several tuplet groups if their
+duration is typed after the fraction.
+@lilypond[quote,verbatim,relative=2]
+\tuplet 3/2 { c8 d e } \tuplet 3/2 { f e d } c2
+\tuplet 3/2 4 { c8 d e f e d } c2
@end lilypond
-This is sometimes used to indicate half-open hi-hats.
+The @code{\times} command with its inverted fraction order
+@code{@var{n}/@var{t}} is still available.
@item
-The Unicode Bidirectional Algorithm is now fully supported for
-single-line markup due to enhanced integration with Pango.
+Introducing two new markup-commands; @code{\draw-dashed-line} and
+@code{\draw-dotted-line}.
-@item
-LilyPond is now licensed under the GNU GPL v3+.
+@noindent
+The dashed-line extends to the whole length given by @var{dest}, if
+@code{full-length} is set to @code{#t} (this is the default) without any
+space at the beginning or end. @code{off} will then be altered to fit.
+To insist on the given (or default) values of @code{on}, @code{off} use
+@code{\override #'(full-length . #f)}. Manual settings for @code{on},
+@code{off} and @code{phase} are possible.
-@item
-In tablature, frets can be indicated with labels other than numbers:
+@noindent
+The dotted-line always extends to the whole length given by @var{dest},
+without any space at the beginning or end. Manual settings for
+@code{off} are possible to get larger or smaller space between the dots.
+The given (or default) value of @code{off} will be altered to fit the
+line-length.

-Layout objects can be printed over a white background, which whites-out objects
-in lower layers which lie beneath:
-
-@lilypond[verbatim,quote,relative=1]
-\time 3/4
-\override Staff.StaffSymbol #'layer = #4
-\once \override Tie #'layer = #2
-b'2.~
-\once \override Staff.TimeSignature #'whiteout = ##t

+Starting with version@tie{}2.17.10, error messages or the
+@code{textedit} @acronym{URI} used for point-and-click
+functionality specify column numbers starting with@tie{}1 rather
+than@tie{}0. The byte offset (also part of @code{textedit}
+@acronym{URI}s) still starts at@tie{}0.
@item
-Chords can be repeated using the @code{q} shortcut:
-
-@lilypond[verbatim,quote,relative=2]
-<c e g>8.-^ q16 q4-^
+The @code{\clef} command supports optional transposition:
+@lilypond[verbatim,quote,relative=1]
+\clef "treble_(8)"
+c2 c
+\clef "bass^[15]"
+c2 c
@end lilypond
@item
-With two-sided mode, margins for odd and even pages can be set using
-@code{inner-margin} and @code{outer-margin}:
-
+The LilyPond syntax of dot-separated words @code{Voice.Accidental}
+has been made interchangeable with @code{#'(Voice Accidental)}, a
+Scheme list of symbols. As one result, code like
@example
-\paper @{
- two-sided = ##t
- inner-margin = 10 \mm
- outer-margin = 20 \mm
-@}
+\override Voice.TextSpanner #'(bound-details left text) = "rit."
@end example
-
-@item
-Paper margin defaults, as specified in @file{ly/@/paper@/-defaults@/-init@/.ly}, apply
-to the default paper size (a4) and are automatically scaled according to the
-paper size chosen.
-
-@item
-All combinations of @code{left-margin}, @code{right-margin} and
-@code{line-width} work now. There is no more need to set @code{line-width}
-manually unless you explicitly want to.
-
-@item
-Support for using an alternative music font, such as Gonville, is now
-added.
-
-@item
-In addition to the existing @code{\hspace} markup command,
-a new @code{\vspace} command has been added to provide an easy
-and flexible way to add vertical space in markups.
-
-@item
-The direction of manual beams can be set with @code{^[} and @code{_[}.
-
-@item
-A version of the breve note head has been added with two vertical lines on each side.
-@lilypond[quote,relative=2]
-\time 4/2
-\override Staff.NoteHead #'style = #'altdefault
-c\breve | b\breve
-@end lilypond
-
-@item
-Instrument names and vocal names now take into account the extent of
-system start delimiters in other staves for their positioning,
-resulting in improved default alignment for left-, center- and
-right-aligned names.

-Intermediate .ps files which are created by LilyPond
-during compilation are now deleted by default. To keep them,
-add the following line to your input files:
+is now equivalent to
@example
-#(ly:set-option 'delete-intermediate-files #f)
+\override Voice.TextSpanner bound-details.left.text = "rit."
+@end example
+or even
+@example
+\override #'(Voice TextSpanner) bound-details.left.text = "rit."
@end example
@item
-Dashed and dotted slurs, phrasing slurs, and ties
-have been made variable thickness, and
-partially dashed slurs are now available:
-@lilypond[quote,relative=2]
-\slurDashed
-c4( d e f) |
-\slurDotted
-g4( f e d) |
-\slurHalfDashed
-c4( d e f)
-@end lilypond
-
-@item
-An eyeglasses markup was added, indicating strongly to look at the
-conductor for instructions:
-@lilypond[quote,relative=2]
-\mark \markup { \eyeglasses }
-c4_\markup { \eyeglasses }
-@end lilypond
-
-@item
-A snap-pizzicato (also known as Bartok-pizzicato) articulation was added:
-@lilypond[quote,relative=2]
-c4\snappizzicato
-@end lilypond
-
-@item
-Tuplet number formatting functions are now available to print other fractions
-and to add notes to the number or fraction:
-@lilypond[quote,relative=2]
-\once \override TupletNumber #'text =
- #(tuplet-number::non-default-tuplet-denominator-text 7)
-\times 2/3 { c4. c4. c4. c4. }
-
-\once \override TupletNumber #'text =
- #(tuplet-number::non-default-tuplet-fraction-text 12 7)
-\times 2/3 { c4. c4. c4. c4. }
-\once \override TupletNumber #'text =
- #(tuplet-number::append-note-wrapper
- (tuplet-number::non-default-tuplet-fraction-text 12 7) "8")
-\times 2/3 { c4. c4. c4. c4. }
-
-\once \override TupletNumber #'text =
- #(tuplet-number::append-note-wrapper tuplet-number::calc-denominator-text "4")
-\times 2/3 { c8 c8 c8 c8 c8 c8 }
-\once \override TupletNumber #'text =
- #(tuplet-number::append-note-wrapper tuplet-number::calc-fraction-text "4")
-\times 2/3 { c8 c8 c8 c8 c8 c8 }
-
-\once \override TupletNumber #'text =
- #(tuplet-number::fraction-with-notes "4." "8")
-\times 2/3 { c4. c4. c4. c4. }
-\once \override TupletNumber #'text =
- #(tuplet-number::non-default-fraction-with-notes 12 "8" 4 "4")
-\times 2/3 { c4. c4. c4. c4. }
+Grob and grob property path no longer need to be specified as two
+separate arguments to commands like @samp{\override} and
+@code{\revert}, allowing for the syntax
+@example
+\override Voice.TextSpanner.bound-details.left.text = "rit."
+@end example
+Since complementary music functions like @samp{\overrideProperty}
+cannot support forms with and without separating space at the same
+time, using a single dotted path is now the preferred form.
+Specifying grob path and grob property path separately, currently
+still supported with @samp{\override} and @samp{\revert} for
+compatibility reasons, is deprecated.
+
+@item
+Due to words now being accepted as symbol function arguments, the
+interfaces of @samp{\accidentalStyle}, @samp{\alterBroken},
+@samp{\footnote} and @samp{\tweak} had to be redesigned where
+optional symbol arguments were involved. Please check the
+respective music function documentation for details.
+
+@item
+Several commands now accept symbol lists (conveniently entered as
+dot-separated words) for various kinds of arguments. These
+include @samp{\accidentalStyle}, @samp{\alterBroken},
+@samp{\footnote}, @samp{\hide}, @samp{\omit},
+@samp{\overrideProperty}, @samp{\shape}, and @samp{\tweak}.
+
+@item
+The bar line user interface has changed. Bar glyphs now resemble the
+appearance of the bar line, so a left repeat sign has to be coded
+as @code{.|:}. The command @code{\defineBarLine} provides an easy way
+to define additional bar line styles.
+
+@item
+Accidentals in the key signature may be printed in octaves other
+than their traditional positions, or in multiple octaves.
