+The baseline of score markups is now taken from the reference
+point (usually the middle of the staff) of the first bottom system
+rather than the top of the bounding rectangle.  The following

+\markup {

+                   \layout { indent=0 } } ,

+LilyPond no longer automatically infers a @samp{\defaultchild}
+context in a context definition with @samp{\accepts} clauses.  Any
+context definition without an explicit or inherited
+@samp{\defaultchild} definition counts as a @samp{Bottom} context
+and will be eligible for rhythmic events and overrides without
+causing the implicit creation of other contexts.  Be sure to
+specify a @samp{\defaultchild} for non-@samp{Bottom} contexts when
+defining them from scratch.

+There is now extensive support for both discant and bass accordion
+register symbols in the @samp{scm accreg} module, see

+Rehearsal marks at the beginning of a line are now placed to the right

+Decimal numbers can now be written directly in music,
+without a hash sign.  Together with the previous change
+in the way object properties are specified, the code to
+change the length of stems has changed from this:
+@example
+\override Stem #'length = #5.6
+e' f' g' a'
+@end example
+to this:
+@example
+\override Stem.length = 5.6
+e' f' g' a'
+@end example
+
+One has to write a digit on both sides of the dot -- values like
+@code{4.} or @code{-.3} are not allowed.
+
+Decimal fractions are also not accepted in @code{\chordmode}.
+
+@item
+A number of shorthands like @code{(}, @code{)}, @code{|},
+@code{[}, @code{]}, @code{~}, @code{\(}, @code{\)} and others can
+now freely be redefined like normal commands.  An example would be
+@lilypond[verbatim,quote]
+"\\{" = (
+"\\}" = )
+"(" = \melisma
+")" = \melismaEnd
+
+\new Staff <<
+  \relative c' {
+    c8 \{ d e f \} % slurred

+The articulation shorthand for @code{\staccatissimo} has been

+Tempo change ranges are now written as @code{\tempo 4 = 60 - 68}

 Grob @code{OctavateEight} was renamed to @code{ClefModifier}.
