v2.0.1

Fixes

• Enharmonic map: Cbb, Fbb, bbC, bbF were off by one semitone (applied single flat instead of double flat)
• Interval table: #11 anglo_saxon label was d11 (diminished), corrected to A11 (augmented)
• Mode brightness: fix ranking to match circle-of-fifths ordering (Locrian=0, Phrygian=1, Aeolian=2, Dorian=3, Mixolydian=5, Ionian=6, Lydian=7)

Maintenance

• Updated all repository URLs after rename (gingo -> gingopy)
• Updated documentation links (MkDocs, README, pyproject.toml)
• PyPI package name remains gingo (unchanged)

All 496 C++ tests pass.

v1.1.0 — Fretboard & FretboardSVG

🪇 Gingo v1.1.0 — Fretboard & FretboardSVG

Fretboard — Guitar fingering engine

• Fretboard.violao(), .cavaquinho(), .bandolim() — factory methods for standard instruments
• Fretboard(tuning, num_frets) — custom instruments with any tuning
• fretboard.fingering(chord) — optimal CAGED-based fingering generation
• fretboard.scale_positions(scale, fret_lo, fret_hi) — scale positions on the neck
• fretboard.positions(note) — all occurrences of a note on the fretboard
• Multi-criteria scoring algorithm: span, position, finger count, sounding strings, barre detection
• 22/24 standard CAGED chord shapes match reference (jguitar.com)

FretboardSVG — SVG renderer for fretboard diagrams

• chord(), fingering(), scale(), note(), positions() — individual diagrams
• field(), progression() — composite layouts (Grid, Horizontal, Vertical)
• full() — full open fretboard visualization
• write() — save SVG to file

Orientation & Handedness

• Orientation: Horizontal (fretboard view) / Vertical (chord box)
• Handedness: RightHanded / LeftHanded
• All FretboardSVG methods support both parameters with smart defaults
• Backward compatible: existing calls produce identical output

New structs & enums

• Tuning, FretPosition, Fingering, StringState
• StringAction (Open, Fretted, Muted), Orientation, Handedness

CLI

• gingo fretboard chord CM --svg chord.svg
• gingo fretboard scale "C major" --svg scale.svg
• gingo fretboard field "C major" --svg field.svg
• --left (left-handed), --horizontal / --vertical (orientation)

Visual showcase

The README now includes SVG examples for all instrument visualizations:

FretboardSVG	PianoSVG
Chord diagrams (vertical/horizontal)	Chord voicings (close/open/shell)
Scale maps on the neck	Scale highlighting
Harmonic field grids	Harmonic field (7 keyboards)
Chord progressions	Full 88-key keyboard
Left-handed support	—
