+The LilyPond G clef has been rotated 1.5 degrees clockwise for improved
+balance. The old and new versions can be compared by looking at the
+documentation:
+@uref{http://lilypond.org/doc/v2.12/Documentation/user/lilypond/The-Feta-font.html#Clef-glyphs,
+old version},
+@uref{http://lilypond.org/doc/v2.13/Documentation/notation/the-feta-font.html#Clef-glyphs,
+new version}.

+Text crescendo spanners can now be added directly using @code{\cresc},
+@code{\dim} and @code{\decresc}.

+The documented syntax of @samp{lilypond} environments in the @LaTeX{}
+mode of @command{lilypond-book} has been changed to conform with
+standard @LaTeX{} syntax: options now come after the environment name:
+@example
+\begin@{lilypond@}[@var{options}] @dots{}
+@end example
+
+The previous syntax with options after @samp{\begin} is still accepted
+by @command{lilypond-book} but deprecated. Something like
+@example
+sed -i '/begin\[/s/begin\(\[[^]]*]\)\(@{lilypond@}\)/begin\2\1/'
+@end example
+
+might do the trick for conversion.

+Aesthetics of shape note heads have been enhanced. Variable line thicknesses
+have been implemented. All note widths have been made consistent.
+Minor shape note commands that use the relative major key for scale steps
+have been added.

+A variant of the segno sign is provided:
