version)

New features:
-------------

* Save Part as MIDI file (save_score_midi)
* Add PerformedPart to represent performances
* Load MIDI as PerformedPart (load_performance_midi)
* Save PerformedPart as MIDI (save_performance_midi)
* Add support for Match files (load_match)

that class (Page, System, Direction)
* Define Incr/Decr loudness/tempo directions
* Add iter_prev/iter_next methods
* Be explicit about kwargs in Note creation
* Add show function to display score, using either MuseScore or Lilypond as
backend

Bug fixes:
-------------

* Better clef support in musicxml export
* export_musicxml: fixes in handle wedge/dashes export
* The order in which simulatenous notes are listed in a timepoint no longer
influences the chord-handling logic in voice estimation, and the musicxml
export.

* Fix in anacrusis handling
* Fix in iter_current_next
* import_musicxml: check for <backup> crossing measure boundary

Other changes:
-------------

* Get rid of deprecated get_prev/next_of_type
* Tuplet/Slur: make use of getter/setter for start/end_note
* Improvements in parse_direction
* expand_grace_notes now simpy sets note durations, without shifting onsets
* Rename strictly_monophonic_voices keyword arg to monophonic_voices in
estimate_voices, and implement (previously unimplemented) functionality: With
monophonic_voice=False, notes with same onset and duration as treated as
chords and assigned to the same voice
* More documentation

--------------------------------------------------

API changes:
-------------

* The TimeLine class has been merged into the Part class

New features:
-------------

* Add `find_tuplets` and `tie_notes` to public API
* New Tuplet class analog to Slur, allows for better musicxml tuplet
support
* Remove deprecated get_starting_objects_of_type/get_ending_objects_of_type (use
iter_starting/iter_ending)

Bug fixes:
-------------

* Multiple fixes in tuplet and slur handling

Other changes:
-------------

* Update package description/long description
* More documentation
* Add separate tuplet and slur test cases

New features:
-------------

* New add_measures function to automatically add measures to a Part
* Add inverted quarter/beat map

Bug fixes:
-------------

* Avoid sharing symbolic_duration dictionaries between notes
* Rework MIDI loading: do not accumulate quantization errors
* Make sure last tied note actually gets tied
* Do not populate symbolic_duration with None when values are missing
* When exporting to musicxml, avoid polyphony within voices by reassigning notes to new voices where necessary
* Filter null characters when exporting musicxml to avoid lxml exception
* Loggin: info -> debug
* Don't use divisions_map
* Fix leftover references to old API
* Fix `add_measures`
