v2.1.0

Minor improvements:

• build with spago@next
• export the normaliseKey function in the Canonical module
• trim spaces from getTitle
• add a normalise function which replaces broken rhythm pairs with the underlying pair of notes and also normalises chords
• allow rests in broken rhythm pairs

v2.0.0

• PureScript v0.15.4
• Header optics have been added; profunctor-lenses is now a dependency
• Some metadata header retrieval functions have been removed in favour of optics
• MeterSignature - Tuple Int Int replaced by
  TimeSignature - { numerator:: Int, denominator:: Int }
• MIDI pitch translation for B# and B## has been corrected
• Decorations can now be applied to chords and tuplets
• Chord symbols appear in the ADT as simple strings (without framing double quotes)
• The Metadata module has been renamed as Utils and many functions moved
  to modules named after the appropriate header

v1.9.0

• Improved volta support - with a new data type: Volta.
• Renamed BarType as BarLine and simplified its parsing. Multiple repeated sections are now supported.
• The Midi module now takes proper account of voltas and multiple repeats.
• Optional key-value properties added to Key headers.

v1.8.0

• Add spago

v1.7.0

• Add support for multiple voices
• Upgrade to purescript-midi v2.2.0 (reduce code bloat)

v1.6.2

• Attach decorations to the note they decorate.
• Or else attach them (free standing) to a typesetting space 'y'.

v1.6.0

• Grace notes are no longer free-standing but incorporated into a GraceableNote. Supported everywhere except before chords.
• The ABC ADT has thus changed to add the GraceableNote type and free standing grace notes are now disallowed.

v1.5.0 Improved continuations

• The parser now parses the continuation and the end of line, with the effect that both this line and the next are coalesced in the ABC ADT as a single music line. This makes life easier for score production.
• Continuation now takes a String parameter - the comment that may live between the backslash continuation marker and eol.

v1.4.0

• Add an explicit Bar constructor to the ADT. i.e. individual bars are properly delineated.
• Rewrite the Transposition module (to the same interface)

v1.3.0

PureScript 0.12
