Release Notes
v0.2.72026-04-11
New

v0.2.62026-04-10
New
- +Pages load significantly faster — the home page and all scale pages are now served from Vercel's CDN edge; first load is noticeably quicker on repeat visits and cold starts
- +"Degree in chord" checkbox moved — the option that shows scale degree numbers relative to the selected chord is now in the chord table footer, just below "Show tension chords"; it appears whenever the display is set to Degree mode
- +Privacy Policy now at /[lang]/privacy — e.g. fretcompass.com/en/privacy; old /privacy links redirect automatically to your language
v0.2.52026-04-03
New
- +Chord comparison now supports 4 chords — you can now select up to 4 chords simultaneously in chord comparison mode; each chord gets its own colour; fretboard dots shared by all 4 show as a 4-way colour split
- +"Intervals in chord" is now a checkbox — the option to show intervals relative to the selected chord's root is now a checkbox below "Show tension chords", visible whenever a chord is selected in interval display mode
- +Enharmonic note picker — clicking a root note that has an enharmonic alternative opens a small popup with the other spelling; in sharp mode: F can be played as E#, C as B#; in flat mode: E can be spelled as F♭, B as C♭; the full scale is re-spelled accordingly (e.g. E# major → E# F## G## A# B# C## D##)
- +♯/♭ toggle — a button next to the root note selector switches all note names between sharps (C#, D#…) and flats (D♭, E♭…); the fretboard, chord table, scale info and URL all update instantly; preference is remembered between sessions
- +Your preferences are now remembered — dark/light mode and the "Show tension chords" setting are saved in your browser and restored on your next visit
- +Language preference remembered — if you previously switched to a different language than your browser default, the app will open in that language automatically
- +More keys indexed by search engines — B♭, E♭, A♭, D♭, G♭, E#, B#, F♭ and C♭ keys now have their own URLs in the sitemap
Fixed
- ·Root note selector always shows the same 12 notes — previously the grid reflected the diatonic spelling of the selected scale; it now always shows a fixed chromatic list
- ·♯/♭ toggle button now shows the mode you're switching to, not the current mode
- ·Chord highlighting fixed in flat keys — clicking a chord in a flat-named key (e.g. E♭ major, B♭ minor) now correctly highlights all fretboard notes

New

v0.2.32026-03-28
New
- +6add9 chord row — shows the 6add9 chord for every scale degree in the "More chords" section; the 6th and 9th are always diatonic, with variants for minor 6th (♭6) and flat 9th (♭9) where applicable (e.g. C6add9, Dm6add9, Em(♭6)add(♭9))
- +Tension chords — a new chord category in the Sus2, Sus4 and 7sus4 rows; the suspended note is lowered by a semitone to the nearest diatonic pitch; shown only in cells where no sus chord exists; toggle with the "Show tension chords" checkbox; labeled in blue-gray to distinguish them from suspended chords
- +Chord diagram close button — a small ✕ in the top-right corner of the voicing diagram lets you dismiss the diagram while keeping the chord highlighted on the fretboard
- +Chord diagrams no longer overflow the screen edge on mobile — diagrams anchored to the first or last column now align to the screen edge instead of overflowing
- +Long chord names in voicing diagrams wrap to two lines so they no longer overlap the close button
Fixed

- ·On mobile, the version badge, language selector and dark/light toggle are now in a single row above the title
- ·Open Graph image — sharing a Fret Compass link on social media now shows a preview card with the key, scale name, instrument and a fretboard graphic; the image adapts to the page language
v0.2.22026-03-27
New
- +Sixth chords added to the chord table — each scale degree shows C6, Dm6, Em(♭6) etc. depending on whether the diatonic 6th is a major 6th or a minor 6th
- +Add9 chords added to the chord table — each scale degree shows Cadd9, Emadd(♭9) etc. depending on the diatonic 9th; note that add9 chords (R–3–5–9) have no 7th, unlike ninth chords (R–3–5–7–9)
- +Sus2 and Sus4 chords added to the chord table — suspended chords have no third; sus2 uses the 2nd and 5th, sus4 uses the 4th and 5th; only shown where the interval is diatonically correct
- +7sus4 and maj7sus4 chords added to the chord table — root, 4th, 5th and 7th (no 3rd); 7sus4 appears where the 7th is dominant (♭7), maj7sus4 where it is major (△7); degrees with a tritone 4th are left empty
- +"More chords" toggle — the chord table now shows only the 3 standard rows (Triad, Seventh, Ninth) by default; Sixth, Add9, Sus2, Sus4 and 7sus4 rows are revealed under a ▼ More chords button
- +Chord table rows now show interval formulas below the row label (R–3–5, R–3–5–7, R–4–5–♭7, etc.) to make the chord structure immediately visible
- +Chord table labels updated to correct music theory terminology in all 6 languages (e.g. Triad, Seventh, Ninth in English; correct equivalents in Hungarian, German, Spanish, French and Italian)

- ·Chord voicing diagrams now always show complete chords — ninth chord voicings previously could omit the 9th note
- ·Mobile chord table now fills the full screen width — columns are equal size and the grid no longer leaves empty space on the right
- ·Ninth chord row color matches the Seventh row — previously used darker shades that looked inconsistent with the rest of the table
