-The bar line user interface has changed. Bar glyphs now resemble the
-appearance of the bar line, so a left repeat sign has to be coded
-as @code{.|:}. The command @code{\defineBarLine} provides an easy way
-to define additional bar line styles.
+Four new Clefs have been added. @emph{Double G}, @emph{Tenor G},
+@emph{Varpercussion} and @emph{varC}.

+Isolated durations in music sequences now stand for unpitched
+notes. This may be useful for specifying rhythms to music or
+scheme functions. When encountered in the final score, the
+pitches are provided by the preceding note or chord. Here are two
+examples where this makes for readable input:
+
+@lilypond[verbatim,quote]
+\new DrumStaff \with { \override StaffSymbol.line-count = 1 }
+\drummode {
+ \time 3/4
+ tambourine 8 \tuplet 3/2 { 16 16 16 }
+ 8 \tuplet 3/2 { 16 16 16 } 8 8 |
+}

-Accidentals in the key signature may be printed in octaves other
-than their traditional positions, or in multiple octaves.

+Beaming exceptions can now be constructed using the
+@code{\beamExceptions} scheme function. One can now write
+
+@lilypond[verbatim,quote,relative=1]
+\time #'(2 1) 3/16
+\set Timing.beamExceptions =
+ \beamExceptions { 32[ 32] 32[ 32] 32[ 32] }
+c16 c c |
+\repeat unfold 6 { c32 } |
@end lilypond
+@noindent
+with multiple exceptions separated with @code{|} bar checks
+(writing the exception pattern without pitches is convenient but
+not mandatory). Previously, setting the beam exceptions would
+have required writing
+
+@example
+\set Timing.beamExceptions =
+#'( ;start of alist
+ (end . ;entry for end of beams
+ ( ;start of alist of end points
+ ((1 . 32) . (2 2 2)) ;rule for 1/32 beams -- end each 1/16
+ )))

+The most common articulations are now reflected in MIDI output.
+Accent and marcato make notes louder; staccato, staccatissimo and
+portato make them shorter. Breath marks shorten the previous
+note.
+
+This behavior is customizable through the @code{midiLength} and
+@code{midiExtraVelocity} properties on @code{ArticulationEvent}.
+See @file{script-init.ly} for examples.
+
+@item
+The PostScript functionality of stroke adjustment is no longer
+applied automatically but left to the discretion of the PostScript
+device (by default, Ghostscript uses it for resolutions up to
+150dpi when generating raster images). When it is enabled, a more
+complex drawing algorithm designed to benefit from stroke
+adjustment is employed mostly for stems and bar lines.
+
+Stroke adjustment can be forced by specifying the command line
+option @samp{-dstrokeadjust} to LilyPond. When generating
+@code{PDF} files, this will usually result in markedly better
+looking @code{PDF} previews but significantly larger file size.
+Print quality at high resolutions will be unaffected.
