- Core refactored to support multiple generator intervals, enabling all regular temperaments including Just Intonation.
- Introduces support for Just Intonation via Prime Limit Tuning construct.
- Custom regular temperaments can be built using Multi-Generator Tunings (e.g., Quarter-Comma-Meantone).
- Full interval arithmetic is now implemented (addition, subtraction, multiplication of intervals).
- New harmonic primitives: Sequences (for note successions with retrograde/inversion) and Interval Fans (relative distances to a tonal center).
- Interval class vectors added for scale analysis.
- Closest frequency approximation for all one-dimensional tuning primitives.
- Documentation completely revamped with organized examples and dedicated pages.
