-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.

-\relative c' { c2 \partcombineApart c | \partcombineChordsOnce e' e }

+The following is a fundamental change in LilyPond's music
+representation: Rhythmic events like @code{LyricEvent} and
+@code{NoteEvent} are no longer wrapped in @code{EventChord} unless they
+have been actually entered as part of a chord in the input. If you
+manipulate music expressions in Scheme, the new behavior may require
+changes in your code. The advantages of making input and music match
+more closely are numerous: music functions previously worked differently
+when used inside or outside of chords. Now they are the same, including
+all the possibilities of argument parsing. You can now use music
+variables inside of chords: a construct like
+@lilypond[quote,ragged-right]
+tonic=fis'
+{ <\tonic \transpose c g \tonic> }
@end lilypond

-@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.
-
-@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.
-
-@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.
-
-@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}.
-

-@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\!
+@noindent
+would have been unthinkable previously. You can use
+@code{#@{@dots{}#@}} for constructing chord constituents. Music
+functions inside of chords are no longer specially treated and thus
+accept the same arguments as outside of chords. @code{\tweak} now works
+on single notes without needing to wrap them in a chord. String number
+indications like @code{\1} can be used on single notes. If you need to
+suppress them in some context, override their @code{stencil} with
+@code{##f}.
+
+@item
+Scheme expressions inside of embedded Lilypond (@code{#@{@dots{}#@}})
+are now executed in lexical closure of the surrounding Scheme code.
+@code{$} is no longer special in embedded Lilypond. It can be used
+unconditionally in Lilypond code for immediate evaluation, similar to
+how @code{ly:export} could previously be used. @code{ly:export} has
+been removed. As a consequence, @code{#} is now free to delay
+evaluation of its argument until the parser actually reduces the
+containing expression, greatly reducing the potential for premature
+evaluation.
+
+@item
+Support for jazz-like chords has been improved: Lydian and altered
+chords are recognised; separators between chord modifiers are now
+treated independently of separators between ``slash'' chords and their
+bass notes (and by default, slashes are now only used for the latter
+type of separator); additional pitches are no longer prefixed with
+``add'' by default; and the ``m'' in minor chords can be customized.
+@ruser{Customizing chord names} for more information.
+
+@item
+The @code{\markuplines} command has been renamed to @code{\markuplist}
+for a better match with its semantics and general Lilypond
+nomenclature.
+
+@item
+The interface for specifying string tunings in tablature has been
+simplified considerably.
+
+@item
+Beams can now have their slopes preserved over line breaks.
+@lilypond[fragment,quote,relative=2]
+\override Beam #'breakable = ##t
+a8[ b c d e f g \bar "" \break f e d c b a]
+\once \override Beam #'positions = #beam::align-with-broken-parts

-@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:
-@example
-\begin@{lilypond@}[@var{options}] @dots{}
-@end example
-
-The previous syntax with options after @samp{\begin} is still accepted
-by @command{lilypond-book} but deprecated. Something like
-@example
-sed -i '/begin\[/s/begin\(\[[^]]*]\)\(@{lilypond@}\)/begin\2\1/'
-@end example
-
-might do the trick for conversion.
+To do this, several callback functions are now deprecated.
+@itemize
+@item @code{ly:beam::calc-least-squares-positions}
+@item @code{ly:beam::slope-damping}
+@item @code{ly:beam::shift-region-to-valid}
+@end itemize
+Furthermore, @code{ly:beam::quanting} now takes an additional argument
+to help calculations over line breaks. All of these functions are now
+automatically called when setting the @code{positions} parameter.
@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.
+In function arguments music, markups and Scheme expressions (as well
+as several other syntactic entities) have become mostly
+interchangeable and are told apart only by evaluating the respective
+predicate.
@item
-A variant of the Segno sign is provided:
-@lilypond[quote,relative=2]
-c4 d e f \bar "S"
-g4 f e d
-@end lilypond
+Music functions (and their close relatives) can now be defined with
+optional arguments.
@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 {

-@end lilypond
+For defining commands executed only for their side-effects,
+@code{define-void-function} is now available.
@item
-A half-open articulation was added:
-@lilypond[quote,relative=2]
-c4\halfopen
+There is a new @code{define-event-function} command in analogy to
+@code{define-music-function} that can be used for defining music
+functions acting as events without requiring a direction specifier
+(@code{-}, @code{^}, or @code{_}) placed before them.

-This is sometimes used to indicate half-open hi-hats.
@item
-The Unicode Bidirectional Algorithm is now fully supported for
-single-line markup due to enhanced integration with Pango.
-
-@item
-LilyPond is now licensed under the GNU GPL v3+.

-
-@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.
+There is a new @code{define-scheme-function} command in analogy to
+@code{define-music-function} that can be used to define functions
+evaluating to Scheme expressions while accepting arguments in Lilypond
+syntax.
@item
-The direction of manual beams can be set with @code{^[} and @code{_[}.
+The construct @code{#@{ @dots{} #@}} can now be used not just for
+constructing sequential music lists, but also for single music events,
+void music expressions, post events, markups (mostly freeing users from
+having to use the @code{markup} macro), markup lists, number
+expressions, context definitions and modifications, and a few other
+things. If it encloses nothing or only a single music event, it no
+longer returns a sequential music list but rather a void music
+expression or just the music event itself, respectively.
@item
-A version of the breve note head has been added with two vertical lines on each side.
