@unnumbered New features in 2.11 since 2.10

@ifhtml
This document is also available in @uref{NEWS.pdf,PDF}. It's part of
the @uref{../,LilyPond Documentation} 
@end ifhtml




@itemize @bullet

@ignore

HINTS

* only show verbatim input for syntax/input changes

* try to be as brief possible in those cases

* don't try to provide real-world examples, they often get too big,
which scares away people.

* Write complete sentences.

* only show user-visible changes. 

@end ignore

@item
The following options are now changed as a @code{-d} sub-option:
@code{--backend}, @code{--safe}, @code{--preview} and
@code{--no-pages} (which became @code{-dno-print-pages}).

@item
Improved testing procedure now catch changes in CPU and memory
performance, page layout, MIDI results and warnings.  This helps to
reduce the number of regression errors during development, resulting
in more stable releases.

See @uref{INSTALL.html#testing} for more information.
@item
Nested properties, such as @code{details} in @code{Slur}, can be
reverted as well.  The syntax for this is

@example
\revert Slur #'(details closeness-factor)
@end example

@item
All line spanners are more flexible now in the configuration of their
end points.  This includes glissando, voice followers, text crescendos
and other text spanners.

@c  with ragged-right we can't see the gliss.
@lilypond[]

  \override Glissando #'bound-details #'right #'text = \markup { \hcenter \bold down }

  \override Glissando #'bound-details #'left #'arrow = ##t

  \override Glissando #'style = #'trill

@item
The environment variable LILYPONDPREFIX has been renamed to
LILYPOND_DATADIR.

@item
Notes or rests, such as a typical end note, that fill an entire
measure are preceded by some more space.

@lilypond[ragged-right]
\relative c' {
  \time 4/4
  s1
  c2. c4
  \time 3/4
  c2.
}
@end lilypond

@item All @code{\score}s in a lilypond-book fragment are now inserted
into the document. Also, toplevel markups don't result in an entire
page.

@item Alterations (such as a sharp and flat) may now be arbitrary
fractions. This allows some forms of microtonal music.  For example,
Turkish makam music uses 1/9th tone alterations.

@lilypondfile{makam.ly}



@item Tie directions may be set with @code{^~} and @code{_~}

@item Tablature now supports harmonics and slides,

@lilypond[fragment,ragged-right,relative=1]
\new TabVoice
{
    <c g'\harmonic> d\2\glissando e\2
}
@end lilypond

This feature was sponsored by Mike Amundsen

@item Horizontal spacing now follows object outlines more
accurately. This allows tighter horizontal spacing.

@lilypond[fragment,ragged-right]
{
  \stemUp c''4...*1/2
  ceses'!
}
@end lilypond


@item Objects that belong outside of the staff are
now positioned automatically to avoid collisions.

@lilypond[fragment,ragged-right,relative=1]
  c''
  \once \override TextScript #'self-alignment-X = #CENTER
  a,^"this doesn't collide with the c"
  b^"this goes above the previous markup"
  a8_"this goes below the dynamic"
  a\f
@end lilypond

@item Staves are spaced vertically using a skyline algorithm. This helps to avoid
uneven vertical spacing.
