 New features in 2.20 since 2.18
 *******************************
 
-   • The music function ‘\\unfoldRepeats’ can now take an optional
+   • It is now possible to move systems with reference to their current
+     position using the ‘extra-offset’ subproperty of
+     ‘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 *note
+     (lilypond-notation)Explicit staff and system positioning:: for more
+     information.
+
+   • It is now possible to add text to analysis brackets through the
+     ‘HorizontalBracketText’ object.

+
+   • The ends of hairpins may now be fine-tuned using the ‘shorten-pair’
+     grob property, which previously only affected text-spanners like
+     ‘TupletBracket’ and ‘OttavaBracket’.  Positive values offset to the
+     right, negative to the left.

+   • In fret-diagrams the distance between frets and the distance
+     between strings is now independently adjustable.  Available are
+     ‘fret-distance’ and ‘string-distance’ as subproperties of
+     ‘fret-diagram-details’.

+   • Accidental rules can now be defined across ‘ChoirStaff’ contexts.
+     Two new rules ‘choral’ and ‘choral-cautionary’ are available that
+     combine the characteristics of ‘modern-voice’ and ‘piano’ or their
+     equivalents with cautionary accidentals.
+
+   • The music function ‘\unfoldRepeats’ can now take an optional
      argument-list specifying which type(s) of repeated music should be
      unfolded.  Possible entries are ‘percent’, ‘tremolo’, ‘volta’.  If
      the optional argument-list is unspecified, ‘repeated-music’ will be
