## [2.1.0] — 2026-04-16
### Added
- **Calculator Tab-System:** 6 Modi über Tab-Leiste erreichbar (Standard, Scientific, Unit, SAT, FAC, STA)
- **Scientific-Modus:** Wurzel, Potenz, Pi, Euler, Vorzeichen-Wechsel + Formel-Helfer (Kreis, Pythagoras, Prozent, Temperatur)
- **Unit-Converter:** 6 Kategorien (Länge, Gewicht, Temperatur, Volumen, Geschwindigkeit, Fläche) mit Live-Konvertierung und Swap
- **Satisfactory Calculator:** Items/Min, Overclock-Power (Exponent 1.321928), Maschinen-Rechner
- **Factorio Calculator:** Assembler-Ratios, Belt-Throughput, Maschinen-Rechner mit Belt-Empfehlung
- **Stationeers Calculator:** Idealgas (PV=nRT), Furnace/Verbrennung, Solar/Batterie-Dimensionierung, Atmosphären-Mixer
### Changed
- Parser um `^` (Potenz, rechts-assoziativ) und `sqrt()` erweitert
- Calculator-Widget Auto-Resize auf 320×480 für komplexe Modi
- ~110 neue i18n-Keys (DE + EN)
---
### v2.0.1 — 16.04.2026
#### Security
- **Background URL validation** — Only `blob:` and `data:image/` protocols allowed in CSS `backgroundImage` (prevents CSS injection via manipulated storage)
- **Import URL validation** — `javascript:`, `data:`, and other unsafe protocols are blocked during JSON import
- **Immutable import mapping** — Imported boards, bookmarks, and notes are sanitized with explicit field selection and string length limits
#### Fixed
- **Widget minimize race condition** — Replaced `setTimeout` with `transitionend` event; `openWidget()` during animation no longer causes display glitch
- **Notes import mutation** — Import now uses `Notes.init()` instead of directly setting `Notes._notes`
- **Complete i18n coverage** — 5 header button tooltips and 3 settings button texts now have `data-i18n` attributes (10 new translation keys)
#### Changed
- **Widget event system** — `WidgetManager` now dispatches `widget:close`, `widget:minimize`, `widget:open` CustomEvents via `EventTarget`. Calculator, Timer, and ImageRef use `WidgetManager.on()` instead of monkey-patching
- **Local favicon icons** — Replaced Google Favicons API with local colored letter icons (deterministic hue per title). Zero external network requests, Brave Shields compatible
- **backdrop-filter fallback** — `@supports not (backdrop-filter)` block with `--bg-solid-fallback` per theme for Brave Shields compatibility
- **Clock interval cleanup** — `setInterval` ID stored in variable
---
### v2.0.0 — 22.03.2026
#### New Features
- **Internationalization (i18n)** — Full DE/EN language support with runtime switching
- Language setting in Settings panel: German, English or Auto-detect (browser language)
- `i18n.js` module with ~220+ string keys, `t(key, vars?)` helper and `data-i18n` HTML attributes
- `_locales/de/` and `_locales/en/` for manifest-level i18n (`__MSG_extName__`, `__MSG_extDesc__`)
- `<html lang>` attribute updates dynamically when language changes
- All modules migrated: dialog, boards, onboarding, notes, calculator, timer, image-ref, data, bookmark-import, storage, settings, widgets, app
#### Technical
- New script load order: `storage → state → i18n → dialog → ...`
- `applyLanguage()` scans DOM for `data-i18n`, `data-i18n-placeholder`, `data-i18n-title`
- Onboarding slides use i18n keys instead of hardcoded text (rendered at display time)
- Clock day/month names via i18n keys instead of hardcoded arrays
- `resolveLang()` helper for DRY language resolution (auto → browser detect)
---
### v1.10.0 — 22.03.2026
#### Themes
- **3 new themes** — Satisfactory (Industrial Desert), Avorion (Deep Void) and Hellion Stealth (Tactical Recon)
- Now **11 themes** total, each with its own accent colors, overlays and font styles
- Satisfactory has increased board alpha (0.65) and stronger blur (12px), a deliberate choice for better readability on a visually busy background
- Avorion uses a radial gradient overlay so the ship in the center of the image stays visible
- Hellion Stealth is the only theme with a `border-left` hover effect in tactical scanner style
---
### v1.9.0 — 22.03.2026
#### New Features
- **Onboarding reworked** — 7 slides instead of 6, new slide explains the widget toolbar with all widgets
- **Gaming Starter Board** — Opt-in during onboarding: pre-filled board with links to Satisfactory, Factorio, Avorion, Minecraft and Star Citizen
- **Settings redesign** — Settings panel slimmed down to 3 sections (Widgets, Data & Help, Danger Zone)
- **Appearance modal** — Theme picker and all display settings combined in one modal instead of spread across the panel
- **Fixed about footer** — Developer info, license and links are now permanently visible at the bottom of the settings panel
- **Project documentation** — `docs/architecture.md`, `docs/widget-schema.md` and `docs/patterns.md` for anyone who wants to fork or contribute
#### Improvements
- All labels and descriptions unified in German, no more language mix
- Dropdown options use theme colors instead of white browser default
- Firefox update URL for store publishing added to `manifest.firefox.json`

- **Accordion settings** — All settings sections collapsible (About and Danger Zone closed by default)
#### Improvements
