Improvements - Improve the performance of saving a large document encoded in Western (ASCII). - Improve overall stability and performance. Fixes - Fix an issue where changes to the “Make file executable” option in a canceled save panel could be applied to a subsequent save. - Fix an issue where the app became unresponsive when a document was automatically updated due to an external modification while an alert for the document was displayed. - Fix an issue where the alerts about inconsistent line endings or an external modification could be displayed twice for the same document. - Fix an issue where text typed in an untitled document while another document was being opened could be lost without warning. - Fix an issue in the file browser where the “Open in New Window” command did not work for the file currently displayed as a preview. - Fix an issue where the Syntax toolbar menu was no longer updated once the toolbar customization dialog was opened. - Fix an issue where wrapped lines could be printed with an incorrect indentation width when hanging indentation was enabled. - Fix several issues in editing commands with multiple cursors or selections. - Fix an issue where the “Shift Left” command could crash the app when the selection started within the indentation. - Fix an issue where the app could crash when selecting a completion candidate in the Touch Bar. - Fix an issue where the app could become unresponsive when modifying the selection word by word in text containing combining characters. - Fix an issue where setting the tab width to zero with AppleScript could crash the app. - Fix an issue where the automatic outdent when typing a closing symbol, such as “}”, removed only a single character instead of a whole indent level in space-indented documents when the tab character is preferred for indentation. - Fix an issue where the “URL Encode” command could fail for selections containing an invalid percent-encoding sequence, such as a standalone “%”. - Fix an issue where expanding the selection to the beginning of the line discarded the selected range ahead of the anchor when the selection was made from left to right. - Fix several issues in modifying the selection in documents containing inconsistent CRLF line endings. - Fix an issue where the insertion point could move to an unexpected position after typing a quotation mark when the Smart Quotes substitution is enabled. - Fix the Portuguese localization.

# Design Brief: Minimal Monochrome

Monochrome palette with a single accent color, hairline dividers, and generous whitespace.

## Design Tokens

```css
:root {
  --background: #c8e07a;
  --surface: #ffffff;
  --foreground: #1c1c1e;
  --muted-foreground: #8e8e93;
  --accent: #111111;
  --radius: 16px;
  --font-heading: "SF Pro Display", ui-sans-serif, system-ui, sans-serif;
  --font-body: "SF Pro Text", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "SF Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #C8E07A (~42%) · Surface #FFFFFF (~34%) · Text #1C1C1E (~9%) · Muted Text #8E8E93 (~7%) · Accent #111111 (~8%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Headline Over Large Product Shot
- Navigation: Minimal Logo + Action
- Theme & density: Light · Airy
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Code & Terminal
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with download app / install extension CTA and no explicit trust bar.
- Visual summary: Minimal Monochrome (Light canvas, airy density) featuring headline over large product shot layout and product ui screenshot / component visuals.

## Avoid

- Multi-stop neon gradients
- Heavy drop shadows
- More than one competing accent color

Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
