@code{stringTunings} property values have changed from a list of
semitones above middle C to a list of LilyPond pitch values.
@item
The vertical spacing engine has been drastically changed, making
it more flexible and easier to control.
+The spacing between staves within a system can now change
+to better use the space on the page.
+User-defined contexts may participate in this flexible spacing,
+depending on how their @code{staff-affinity} is defined.
+Some page formatting variables (@code{page-top-space},
+@code{between-system-space -padding}, and
+@code{before- between- after-title-space}) have been replaced
+by flexible vertical dimensions.
