+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 }
+@end lilypond
+
+@item
+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}.
