+A new style of whiteout that approximates the contours of a glyph's
+outline is now available using @code{whiteout-style}. The shape of the
+white background is produced from multiple displaced copies of the
+glyph. The @code{thickness} of both the new @code{outline} style and
+the default @code{box} style, as a multiple of staff-line thickness, can
+be customized.

+When outputting MIDI, LilyPond will now store the @code{title}
+defined in a score's @code{\header} block (or, if there is no
+such definition on the @code{\score} level, the first such
+definition found in a @code{\header} block of the score's
+enclosing @code{\bookpart}, @code{\book}, or top-level scope)
+as the name of the MIDI sequence in the MIDI file. Optionally,
+the name of the MIDI sequence can be overridden using the new
+@code{midititle} @code{\header} field independently of
+@code{title} (for example, in case @code{title} contains markup
+code which does not render as plain text in a satisfactory way
+automatically).
+
+@item
+Music (and scheme and void) functions and markup commands that
+just supply the final parameters to a chain of overrides, music
+function and markup command calls can now be defined in the form
+of just writing the expression cut short with @code{\etc}.
+

+
+@item
+LilyPond functions defined with @code{define-music-function},
+@code{define-event-function}, @code{define-scheme-function} and
+@code{define-void-function} can now be directly called from Scheme
+as if they were genuine Scheme procedures. Argument checking and
+matching will still be performed in the same manner as when
+calling the function through LilyPond input. This includes the
+insertion of defaults for optional arguments not matching their
+predicates. Instead of using @code{\default} in the actual
+argument list for explicitly skipping a sequence of optional
+arguments, @code{*unspecified*} can be employed.
+
+@item
+Current input location and parser are now stored in GUILE fluids
+and can be referenced via the function calls @code{(*location*)}
+and @code{(*parser*)}. Consequently, a lot of functions
+previously taking an explicit @code{parser} argument no longer do
+so.
+
+Functions defined with @code{define-music-function},
+@code{define-event-function}, @code{define-scheme-function} and
+@code{define-void-function} no longer use @code{parser} and
+@code{location} arguments.
+
+With those particular definitions, LilyPond will try to recognize
+legacy use of @code{parser} and @code{location} arguments,
+providing backwards-compatible semantics for some time.
+
+@item
+In the "english" notename language, the long notenames for pitches
+with accidentals now contain a hyphen for better readability. You
+now have to write
+@example
+\key a-flat \major
+@end example
+instead of the previous
+@example
+\key aflat \major
+@end example
+
+Double accidentals do not get another hyphen, so the Dutch
+@code{cisis} has the long English notename @code{c-sharpsharp}.
+
+@item
+The visual style of tremolo slashes (shape, style and slope)
+is now more finely controlled.

+Page numbers may now be printed in roman numerals, by setting the
+@code{page-number-type} paper variable.

+@item
+It is now possible to use @code{\time} and @code{\partial}
+together to change the time signature in mid measure.

+
+@item
+Improved horizontal alignment when using @code{TextScript},
+with @code{DynamicText} or @code{LyricText}.
+
+@item
+A new command @code{\magnifyStaff} has been added which scales staff
+sizes, staff lines, bar lines, beamlets and horizontal spacing generally
+at the @code{Staff} context level. Staff lines are prevented from being
+scaled smaller than the default since the thickness of stems, slurs, and
+the like are all based on the staff line thickness.
+
+@item
+@code{InstrumentName} now supports @code{text-interface}.
+
+@item
+There is now support for controlling the @q{expression level} of
+MIDI channels using the @code{Staff.midiExpression} context property.
+This can be used to alter the perceived volume of even sustained notes
+(albeit in a very @q{low-level} way) and accepts a number value between
+@code{0.0} and @code{1.0}.
+
+@example
+\score @{
+ \new Staff \with @{
+ midiExpression = #0.6
+ midiInstrument = #"clarinet"
+ @}
+ <<
+ @{ a'1~ a'1 @}
+ @{
+ \set Staff.midiExpression = #0.7 s4\f\<
+ \set Staff.midiExpression = #0.8 s4
+ \set Staff.midiExpression = #0.9 s4
+ \set Staff.midiExpression = #1.0 s4
+
+ \set Staff.midiExpression = #0.9 s4\>
+ \set Staff.midiExpression = #0.8 s4
+ \set Staff.midiExpression = #0.7 s4
+ \set Staff.midiExpression = #0.6 s4\!
+ @}
+ >>
+ \midi @{ @}
+@}
+@end example
+
+@item
+Support for making it easier to use alternative @q{music} fonts other
+than the default Emmentaler in LilyPond has been added. See
+@uref{http://fonts.openlilylib.org/} for more information.
+
+@item
+Grobs and their parents can now be aligned separately allowing
+more flexibility for grob positions. For example the @q{left} edge of a
+grob can now be aligned on the @q{center} of its parent.
+
+@item
+Improvements to the @code{\partial} command have been made to
+avoid problems when using multiple, parallel contexts.
+
+@item @code{\chordmode} can now use @code{< >} and @code{<< >>}
+constructs.
+
+@item
+A new command @code{\tagGroup} has now been added. This complements
+the existing @code{\keepWithTag} and @code{\removeWithTag} commands.
+For Example:
+
+@example
+\tagGroup #'(violinI violinII viola cello)
+@end example
+
+declares a list of @q{tags} that belong to a single @q{tag group}.
+
+@example
+\keepWithTag #'violinI
+@end example
+
+Is now only concerned with @q{tags} from @q{violinI}’s tag group.
+
+Any element of the included music tagged with one or more tags from the
+group, but @emph{not} with @var{violinI}, will be removed.
+
+@item
+The @code{\addlyrics} function now works with arbitrary contexts
+incuding @code{Staff}.
+
+@item
+String numbers can now also be used to print roman numerals
+(e.g. for unfretted string instruments).

The @code{thin-kern} property of the @code{BarLine} grob has been
renamed to @code{segno-kern}.
\new Staff { r16 c'16 ~ 8 ~ 4 ~ 2 | }
@end lilypond
+@item
+@code{\displayLilyMusic} and its underlying Scheme functions no
+longer omit redundant note durations. This makes it easier to
+reliably recognize and format standalone durations in expressions
+like
+@example
+@{ c4 d4 8 @}
+@end example
+
@item
Beaming exceptions can now be constructed using the
@code{\beamExceptions} scheme function. One can now write
