v0.452 current

iOS 26 gesture regression workaround forward-ported from v0.400 fork.
ImmediatePanGestureRecognizer fully integrated into main branch.
Key flash confirmed working post-fork merge.
Shift state handling verified on both iPhone and iPad post-merge.
Brochure and user manual documentation produced.

v0.434

Slide-to-type removed. Gesture architecture conflicted irreconcilably with balloon gesture recognition.
Website updated to remove slide-to-type references.

v0.400 iOS 26 gesture fork

Apple regression (FB19394663 / FB19405284): UIPanGestureRecognizer no longer fires .began on stationary contact in keyboard extensions on iOS 26.x.
Workaround: ImmediatePanGestureRecognizer subclass overrides touchesBegan to force state = .began immediately.
Fork created to isolate and test workaround before forward-porting.

v0.900 pre-release milestone

Version label removed from spacebar.
ContentView version synced.
Contact email confirmed: SciMathKeyboard@gmail.com.
All documentation updated.

v0.322

Stabilisation work.
Regression work on flashKey / darkPress / letterTouchUp interaction.

v0.319 sync milestone

iPad globe key: tap advances to next keyboard, long-press opens picker via handleInputModeList(from:with:).
Both source files synced to same version.

v0.313

Fixed iPad comma/period insertion via accessibilityIdentifier.

v0.188

iPhone landscape keyboard height corrected: keyH now orientation-aware (isPad ? 84 : isLandscape ? 36 : 46).

v0.185

iPad shift-up hint characters on ABC layer: grey secondary glyphs above each key matching stock iPadOS layout.
Font weight reverted to .regular (v0.183 experiment with .light was an optical illusion caused by missing hints).
Title vertical alignment set to .bottom on iPad ABC keys with hints.
Return key on iPad row 2 flexes to fill remaining row width.

v0.183

iPad corner radius 14pt (vs 11pt iPhone), key gap 8pt (vs 6pt iPhone).

v0.182

iPad key height bumped from 56pt to 84pt to match stock iPad key height.

v0.181

Stagger applied to iPad number/symbol/sci rows 2 and 3.
Fixed toggle label on #+= layer: now shows "sci" (not "123"), restoring correct layer cycle.

v0.162 R

Spacebar long-press trackpad cursor mode: labels blank via alpha walk, horizontal drag moves caret via adjustTextPosition(byCharacterOffset:).
GeometryDiagnostic call site removed (debug artefact).
