+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
-Lyrics above a staff must have their @code{staff-affinity} set to
-@code{DOWN} or must have their @code{alignAboveContext} property
-set in order to be properly aligned. For more information, see
-@ruser{Placing lyrics vertically}.
-
-@item
-@code{stringTunings} property values have changed from a list of
-semitones above middle C to a list of LilyPond pitch values.
-convert-ly will handle the change automatically where the value
-of @code{stringTunings} is set to a Scheme constant value.
-
-New commands @code{makeStringTuning} and @code{contextStringTuning}
-allow the creation of string tunings in the form of a Lilypond
-chord construct.
+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
-By using @code{\cueDuringWithClef}, cue notes can now also have their own
-clef, which is correctly reset at the end of the cue notes. At the begin
-of each line, the standard clef is still displayed, but the cue clef is
-shown after the time/key signature in smaller size.

-Note names can be selected with a new
-@code{@bs{}language "italiano"} command, which
-can be used in safe mode. The old
-@code{@bs{}include "italiano.ly"} syntax is
-still supported for now, but will be deprecated
-in the future.
-
-@item
-autobeaming 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.
+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 part-combiner's decision to combine/not combine notes can now be customized
-@lilypond[quote,relative=2]

@item
-Tablature staves show fret numbers only by default. To get the
-former style, @code{\tabFullNotation} is provided.
-
-@item
-Funk-style and Walker-style shape notes have been added.
-
-@item
-Rests will no longer keep a staff alive if @code{\RemoveEmptyStaffContext}
-is used.
-
-@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.
+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 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.

-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.
+This is mainly useful for writing music functions that need to
+have some property changed just for the duration of the function.
@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}.
-
+@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
-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
-
+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:

+@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.

-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 @{

-
-@item
-In addition to the existing @code{\hspace} markup command,

+Since complementary music functions like @samp{\overrideProperty}

+Specifying grob path and grob property path separately, currently
+still supported with @samp{\override} and @samp{\revert} for

+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

+The bar line user interface has changed. Bar glyphs now resemble the
