+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

+The music and grob property @code{spanner-id} for distinguishing
+simultaneous slurs and phrasing slurs has been changed from a

+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]

+@end lilypond
+and
+@example
+\tagGroup violin,oboe,bassoon

+Such lists may also be used in expressions for assignments, sets,
+and overrides. This allows usage such as

+Association list elements could previously be assigned values

+ \void \displayScheme \system-system-spacing.basic-distance
+@}

All of @code{\override}, @code{\revert}, @code{\set}, and

-The @code{whiteout} grob property and @code{\whiteout} markup command
-now create a white background built from multiple displaced copies of
-the glyph in order to approximate the contours of its outline.
-The previous rounded box white background can be achieved with the
-new @code{whiteout-box} grob property and @code{\whiteout-box} markup
-command. Setting the @code{whiteout} property to a number now sets
-the thickness of the white outline as a multiple of staff-line
-thickness. Similarly, overriding the @code{thickness} property of
-the @code{\whiteout} markup command sets the thickness of the white
-outline it produces.
