+It is now possible to move systems with reference to their current
+position using the @code{extra-offset} subproperty of
+@code{NonMusicalPaperColumn.line-break-system-details}. Both vertical
+and horizontal changes are possible. This feature is especially useful
+for making slight adjustments to the default vertical position of
+individual systems. See @ruser{Explicit staff and system positioning} for

+The ends of hairpins may now be fine-tuned using the @code{shorten-pair}

+Accidental rules can now be defined across @code{ChoirStaff} contexts.

+The music function @code{\unfoldRepeats} can now take an
+optional argument-list specifying which type(s) of repeated music
+should be unfolded. Possible entries are @code{percent}, @code{tremolo},
+@code{volta}.
+If the optional argument-list is unspecified, @code{repeated-music} will be
+used, unfolding all.

+@item
+A new @code{output-attributes} grob property is now used for svg output
+instead of the @code{id} grob property. It allows multiple attributes
+to be defined as an association list. For example, @code{#'((id . 123)
+(class . foo) (data-whatever . @qq{bar}))} will produce the following
+group tag in an SVG file: @code{<g id=@qq{123} class=@qq{foo}

+Slurs and phrasing slurs may now be started from individual notes
+in a chord. Several simultanous slurs per @code{Voice} need to be
+distinguished by @code{spanner-id} setting.

+The music and grob property @code{spanner-id} for distinguishing
+simultaneous slurs and phrasing slurs has been changed from a
+string to a @q{key}, a non-negative integer or symbol.

+Blocks introduced with @code{\header} can be stored in variables
+and used as arguments to music and scheme functions and as the

+a Guile module.
+
+While @code{\book}, @code{\bookpart}, @code{\score}, @code{\with},
+@code{\layout}, @code{\midi}, @code{\paper} blocks can be passed

+types.

+Dot-separated symbol lists like @code{FretBoard.stencil} were
+already supported as of version@tie{}2.18. They may now also
+contain unsigned integers, and may alternatively be separated by
+commata. This allows usage such as
+@lilypond[quote,verbatim]
+{ \time 2,2,1 5/8 g'8 8 8 8 8 }
+@end lilypond
+and
+@example
+\tagGroup violin,oboe,bassoon
+@end example
+
+@item
+Such lists may also be used in expressions for assignments, sets,
+and overrides. This allows usage such as
+@lilypond[quote,verbatim]
+{ \unset Timing.beamExceptions
+ \set Timing.beatStructure = 1,2,1
+ g'8 8 8 8 8 8 8 8 }

+Association list elements could previously be assigned values
+individually (for example, paper variables like
+@code{system-system-spacing.basic-distance}). They may now be
+also referenced in this manner, as with
+@example
+\paper @{
+ \void \displayScheme \system-system-spacing.basic-distance
+@}
+@end example
+
+In combination with the previously mentioned changes, this allows
+setting and referencing pseudovariables like @code{violin.1}.

+LilyPond source files may now be embedded inside the generated PDF files.
+This experimental feature is disabled by default and may be regarded as unsafe,
+as PDF documents with hidden content tend to present a security risk.
+Please note that not all PDF viewers have the ability to handle embedded
+documents (if not, the PDF output will appear normally and source files
+will remain invisible). This feature only works with the PDF backend.

+There are two new page breaking functions. @code{ly:one-page-breaking}

+line and adjusting the page width accordingly, however it also
