## Version history (last 4 releases)

### 1.3.3 — 2025-11-11

Improved Guitar/Bass harmonic mode so perfect fourths and fifths now respond reliably, even on low fundamentals.
Simplified the preset to focus on the most stable partials (Fundamental, P4, P5, Octave, Oct+5th, 2nd Octave) for a cleaner tuning experience.
General stability and detection tweaks to keep the overtone display snappy and accurate.

### 1.3.2 — 2025-11-03

Updated app icon to match the new season.
Tweaked overtone fade so harmonics drop off quickly after you stop playing.
Miscellaneous UI and stability improvements.

### 1.3.1 — 2025-10-09

We adjusted the piano Wave mode layout to fix edge clipping and reorganized the Hz toggle and lock indicators so they’re easier to read.

### 1.3.0 — 2025-10-07

No release notes.
