release: 1.3.59

release: 1.3.59

===========

* Rewrote key sig support.  Now key signature can also be controlled
by setting keySignature and localKeySignature properties, eg.

	\property keySignature = #'((2 . -1) ( 4 . -1) (6 . -1))

sets a key signature of `es ges bes' (an unusual key signature).

Keys are internally represented as transpositions of the c-major
scale. Printing the key signature for a scale is done by filtering out
all non-natural accidentals.

* Removed support for \keysignature, and \key something \minor; Newkey
is now obsolete.
