7## [0.11.0] - 2025-10-07
8
9### Added
10- **Auto-open omnibox on blank panes**: Omnibox automatically opens when a new pane is created with about:blank, providing immediate search/navigation access
11- **Configurable default zoom**: Added `default_zoom` config (defaults to 1.2/120%). Per-domain zoom still overrides this
12- **Pin/favorite sites**: Pin websites from history or quick access to prioritize them in "Jump back in" section. Uses localStorage persistence with star icons for pin/unpin actions
13- **Zellij-style stacked panes**: Added Ctrl+P → 's' to stack panes instead of splitting, with Alt+Up/Down navigation between stacked panes. Features collapsed page title bars showing  for inactive panes and full WebView interaction for the active pane. Includes GTK4 CSS styling for proper visual feedback
14- **Stacked pane favicons**: Title bars display site favicons with async caching. Click title bars to switch between stacked panes
15- **Color palette configuration**: Light and dark color palettes now configurable in `appearance` config with semantic tokens (background, surface, text, muted, accent, border). Injected as CSS custom properties at document start
16- **Search shortcut badges**: Visual badges in omnibox input showing active shortcut prefix (e.g., "gh:", "npm:") with description labels
17- **Search shortcuts API**: Frontend bridge to fetch search shortcuts from backend `/api/config` endpoint with automatic normalization
18
19### Changed
20- **Terminal-style UI theme**: Monospace fonts (JetBrains Mono, Fira Code), sharp corners (no border-radius), dashed borders, adjusted shadows and spacing throughout omnibox components
21- **History suggestions**: Use favicon from database when available, omit automatic search shortcuts from suggestions (rely on explicit prefix commands)
22- **Search shortcuts defaults**: Updated defaults to include ddg, go, mdn, npm packages while reordering others
23- **Chrome user agent**: Updated to version 141.0.0.0 for better site compatibility
24- **CSS color system**: Removed hardcoded theme colors, now use dynamic CSS custom properties from Go-injected palette
25- **History item layout**: Removed "• domain" from titles, now highlight domain within the full URL using same color as title text
26- **Quick access logic**: Removed 20-item limit, now shows all sites with 2+ visits (pinned sites bypass visit requirement)
27- **History pagination**: Show 15 items initially (up from 10) with "Show N more" button
28- **Homepage layout**: Redesigned with improved visual hierarchy and dynamic color tokens
29- **Favicon handlers**: All webviews now register favicon change handlers for consistent caching across panes
30
31### Fixed
32- **Mobile URL overflow**: Fixed long URLs breaking layout on narrow screens by adding proper width constraints and CSS fixes
33- **GTK shortcut GLib-CRITICAL error**: Fixed NULL string assertion in shortcut callback system
34- **SVG favicon handling**: Skip SVG favicons to prevent conversion errors (no raster conversion dependencies)
35- **Focus management architecture**: Refactored workspace focus system from `active` field to `currentlyFocused` with dedicated FocusManager for improved reliability and consistency across pane operations
36- **Stacked pane focus conflicts**: Fixed focus stealing issues in stacked panes by implementing focus-aware navigation that preserves active pane when spawning siblings
37- **WebView title updates**: Enhanced webview title change handling to properly update stacked pane title bars in addition to database storage
38- **GTK4 widget lifecycle**: Improved widget parenting/unparenting operations with proper GTK4 validation and automatic cleanup to prevent critical warnings
39- **Stacked pane close behavior**: Fixed remaining pane becoming non-interactable (gray background) when closing stacked panes via Ctrl+W or Ctrl+P+X. Added proper widget visibility restoration and focus management during stack-to-regular conversion
40- **Stacked pane title updates**: Fixed collapsed panes not showing current page titles when switching between stacked panes. Now follows Zellij-style layout where hidden panes display their up-to-date page titles in title bars with correct positioning above and below the active pane
41
42## [0.10.0] - 2025-09-24
43
44### Added
45- **Print functionality**: Added Ctrl+Shift+P shortcut to open native print dialogs from any pane. Ctrl+P is blocked at WebKit level to prevent conflicts with pane mode shortcuts
46- **WebKit native favicon detection**: Implemented WebKit's built-in favicon database for automatic favicon detection and URI storage. Enhanced favicon support for all formats (PNG, SVG, ICO) without external dependencies
47
48### Changed
49- **Homepage redesign**: Brutal design with component-scoped styling, dynamic height matching, inline domain-URL layout with fade effects, and tighter spacing
50
51### Fixed
52- **WebView teardown and memory management**: Implemented comprehensive cleanup system to prevent crashes during WebView destruction. Added JavaScript teardown functionality with cleanup handlers for all event listeners, intervals, and global state. Enhanced pane cleanup with proper controller detachment and GTK widget detachment sequencing. Added WebView validity checks before JavaScript evaluation and improved workspace manager pane closing logic with better popup handling
53- **Ctrl+W pane closing**: Fixed Ctrl+W shortcut to properly close active panes including popups. Implemented active WebView detection and proper popup vs regular pane handling via OnWorkspaceMessage for consistent cleanup
54- **WebView script injection segfault**: Fixed segmentation violation when injecting JavaScript into destroyed WebViews during message handling. Added IsDestroyed() safety check to prevent GTK widget corruption
55- **Alt+Arrow workspace navigation**: Fixed Alt+Arrow keys not working for pane navigation after WebView focus changes. Implemented C-level to GTK4 shortcut bridge that ensures workspace navigation works consistently across all panes
56- **Global shortcuts protection**: Fixed window shortcuts (Ctrl+L, Ctrl+F, F12) not working in new panes due to overly aggressive webpage protection. Window shortcuts now properly bubble up to GTK while pane shortcuts remain blocked from webpages. Resolves omnibox and developer tools not responding to keyboard shortcuts in newly created panes
57- **Omnibox keyboard event isolation**: Fixed keyboard event leakage from omnibox to underlying webpages that caused unintended page actions (e.g., typing 's' in omnibox triggering GitHub search). Implemented WebKit-level main-world event blocking that activates when omnibox opens, preventing page JavaScript from receiving keyboard events while preserving native GTK shortcuts (Ctrl+L, Ctrl+F, etc.) and omnibox functionality
58- **Active pane detection**: Replaced complex pane ID abstraction with persistent webview IDs, fixing omnibox unresponsiveness after navigation. Omnibox now works immediately after page navigation without requiring mouse movement
59- **Workspace architecture**: Simplified focus tracking by removing URI change handlers and pane ID injection complexity, improving reliability and reducing codebase by 85 lines
60- **WebView ID propagation**: Added webview ID request/response mechanism for stub builds to ensure JavaScript side knows its webview ID for proper focus validation
61- **Workspace theme integration**: Fixed white borders on inactive panes by implementing dynamic border colors based on GTK theme preference (dark mode: #333333 borders, light mode: #dddddd borders)
62- **GTK window background**: Added theme-aware window and pane background colors to prevent white bleeding through transparent elements
63- **Print dialog window handling**: Fixed GTK window destroy errors during WebView cleanup by only destroying windows when CreateWindow was actually enabled
64- **Modifier key logging noise**: Filtered out Ctrl, Shift, Alt, and Super key presses from accelerator miss logging to reduce console spam
65
66## [0.9.0] - 2025-09-22
67
68### Added

71- **Window-level global shortcuts**: Centralized shortcut handling to prevent conflicts between multiple WebView instances
72- **Workspace configuration**: New config section with Zellij controls toggle, pane mode bindings, tab shortcuts, and popup behavior settings
73- **Configurable workspace styling**: Pane border appearance (width, color, transition duration, radius) now customizable via config with proper viewport stability
74- **Popup handling for tiling WM**: Complete popup window support where popups open as workspace panes instead of floating windows, respecting tiling window manager design principles
75- **Universal popup auto-close**: Popup windows (OAuth, window.open(), etc.) automatically close when JavaScript calls window.close(), providing standard browser behavior adapted for workspace panes
76- **Advanced popup deduplication system**: Intelligent duplicate popup prevention with SHA256 fingerprinting and 200ms debounce window to eliminate popup spam

80
81### Improved
82- WebKit integration now forces GPU compositing by default while still honoring explicit config overrides.
83- Smooth scrolling is enabled (when supported) so wheel and gesture animations feel closer to Chromium/Firefox.
84- Title updates, zoom persistence, and domain zoom lookups are now done off the GTK main thread with results marshalled back safely, eliminating UI hitches during navigation.
85- Added optional DOM-level zoom (enabled by default) to avoid native viewport rescaling; falls back to WebKit zoom if the CSS path fails.
86- DOM zoom now seeds the saved level before the first paint and reuses it during document-start scripts, preventing pages from flashing back to 100%.
87- Native accelerator bridge debounces duplicate GTK key events earlier, so Ctrl±/Ctrl+0 only fires once per physical key press.
88- Omnibox-triggered navigations now reuse the navigation controller, so saved zoom levels are applied before first paint and redundant lookups are avoided.
89- Configuration loading writes the missing `use_dom_zoom` flag into existing config files so DOM zoom defaults persist without manual edits.
90- Omnibox UI now relies on shared Tailwind theme tokens and the injected color-scheme service for light/dark parity.
91- Omnibox overlay now self-heals if hostile pages remove the injected shadow host, ensuring Ctrl/Cmd+L works everywhere.
92- Navigation shortcuts changed from Alt+Arrow to Ctrl/Cmd+Arrow for better workspace compatibility.
93- GUI components now support workspace-aware focus management with pane-specific event handling.
94- **Global zoom shortcuts**: Unified zoom handling at window level (Ctrl+/=/0/-) ensuring zoom applies to currently active pane in multi-pane workspace
95- **Workspace focus management**: Enhanced focus throttling (100ms) and active state tracking to prevent infinite loops and conflicts between panes
96- **Popup management**: Intelligent popup vs tab detection based on window features, with improved auto-close logic for OAuth and login flows
97- **Console logging**: WebView ID context injection for better debugging and log correlation across multiple panes
98
99### Changed

337   - Highlighting: yellow for all matches; active match in orange for clarity.
338   - Match list with context (right side stops at nearest punctuation: . , ; : -).
339   - Navigation UX:
340     - ArrowUp/Down move selection and scroll the overlay list (page scroll disabled while open).
341     - Enter centers on the active match and closes; Shift+Enter goes to previous; Alt+Enter centers without closing.
342     - Hover focuses input and selects list items; click outside closes the overlay.
343     - Faded overlay with subtle blur when reviewing matches; opacity restores on input focus/typing.
344   - Programmatic API: `OpenFind(initial)`, `FindQuery(q)`, `CloseFind()` on `WebView`.
345
346### Changed
347- Performance‑first defaults retained:
348  - Cache model set to “WebBrowser”, page cache enabled, DevTools available.
349  - No implicit memory pressure or GC enabled by default; all memory tuning is opt‑in.
350
351### Removed
352- Deprecated offline app‑cache calls eliminated (no‑ops) to avoid warnings and brittle builds.
353
354### Fixed
355- Homepage Recent History layout:
356  - Show single-line entries as “{Title} – {Domain} – {URL}”.
357  - Truncate long URLs with a gradient fade; prevent horizontal overflow.
358  - Adjusted styling so URL is darker for readability.
359- Search shortcuts and config interop:
360  - Backend SearchShortcut now serializes `url`/`description` with JSON tags.
361  - Frontend normalizes field casing and extracts base URLs, handling `%s` and `{query}` templates.
362  - Omnibox shortcut parsing now URL-encodes queries and supports `%s` placeholders.
363- Input and navigation reliability (GTK4/WebKitGTK 6):
364  - Capture-phase key controller to ensure accelerators fire consistently.
365  - Do not consume normal left/right clicks; only mouse buttons 8/9 trigger back/forward.
366  - Added Alt+ArrowLeft/Right navigation and enabled two-finger swipe back/forward when supported.
367  - Added Ctrl+scroll zoom in/out; refined accelerator matching so Ctrl− works across layouts.
368  - Removed layout-specific hacks; added diagnostic logs for raw minus key events.
369- Zoom persistence:
370  - Added WebView zoom-changed hook; save per-domain zoom to SQLite on every change.
371  - Log on successful save: “saved X.XX for domain.tld” and on load: “loaded X.XX for domain.tld”.
372  - Load and log initial zoom level on startup and on every navigation.
373- Build/dev ergonomics:
374  - Makefile loads `.env.local`; supports overriding `GOMODCACHE`, `GOCACHE`, `GOTMPDIR` for sandboxed builds.
375 - WebKit CGO hardening and API compatibility:
376   - Apply memory pressure settings to `WebKitNetworkSession` (correct signature) when enabled.
377   - Guarded C wrappers remove deprecation warnings across header variants; builds succeed on WebKitGTK 6.
378
379## [0.2.0] - 2025-09-10
380
381### Added
382- WebKitGTK 6 (GTK4) migration for the built‑in browser window:
383  - WebView constructed via `g_object_new(WEBKIT_TYPE_WEB_VIEW, …)` with a fresh `WebKitUserContentManager`.
384  - `WebKitNetworkSession` with persistent cookies (SQLite) and cache directories.
385- Native UCM messaging restored via `script-message-received::dumber` (JSCValue*), removing the JS fallback bridge.
386- Rendering mode controls:
387  - CLI flag `--rendering-mode=auto|gpu|cpu` and `DUMBER_RENDERING_MODE` env.
388  - In‑app status endpoint `dumb://homepage/api/rendering/status`.
389- Native zoom shortcuts at the WebKit layer (Ctrl/Cmd+=, +, −, 0) and GTK4 input controllers for keyboard/mouse.
390- AZERTY keyboard fix: treat underscore as minus for zoom‑out.
391- Runtime theme synchronization: watch GTK `gtk-application-prefer-dark-theme` and update page color‑scheme live.
392- Makefile target `check-webkit` to print `pkg-config` versions of GTK4/WebKitGTK 6.0/JSC 6.0.
393- Documentation updates:
394  - README now targets WebKitGTK 6 (GTK4) and lists GStreamer package requirements for Arch and Debian/Ubuntu.
395  - CLAUDE notes updated with migration status, GPU/Vulkan path, runtime theme sync, and persistence.
396
397### Changed
398- Build flags and includes now target `webkitgtk-6.0`, `gtk4`, and `javascriptcoregtk-6.0`.
399- GTK4 APIs for windowing and event handling (GtkEventController, GtkGestureClick) replace GTK3/GdkEvent paths.
400
401### Removed
402- Legacy WebKit2GTK constructors and container APIs.
403- JavaScript fallback for UCM message bridging.
404
405### Fixed
406- Header/enum compatibility for hardware acceleration policy and cookie policy across WebKit header variants.
407- Linker error for `on_theme_changed` and gpointer usage in signal connections.
408- Crashy paths mitigated by default “media safe” startup (can be disabled via `DUMBER_MEDIA_SAFE=0`).
409
410### Notes
411- GPU rendering path leverages GTK4’s renderer (Vulkan/OpenGL). Mode `auto` uses GPU when available and falls back gracefully to CPU.
412- WebKitGTK relies on GStreamer; install recommended packages for audio/video (see README).
413
414## [0.1.0] - 2025-09-09
415
416### Added
417- Initial project scaffolding, build system, and dependencies.
418- Unified CLI + GUI architecture with search shortcuts and fuzzy parsing.
419- Wails v3‑alpha browser integration (early phase).
420- Global keyboard controls with script injection (zoom/devtools, etc.).
421- Native WebKit2GTK backend migration:
422  - Custom `dumb://` scheme and `/api` endpoints: `/config`, `/history/recent`, `/history/search`, `/history/stats`.
423  - UserContentManager omnibox injection and theme initialization.
424  - Persistent WebsiteDataManager with cookies.sqlite; per‑domain zoom and title persistence.
425  - Keyboard/mouse accelerators (including mouse back/forward); debounced triggers.
426  - Homepage switched to first‑party API fetches; removed @wailsio/runtime usage.
427- Documentation and licensing: README enhancements and LICENSE added.
428
429### Changed
430- Replaced Wails runtime with native WebKit2GTK CGO bindings and homepage API.
431- Improved asset resolution and logging for the `dumb://homepage` scheme.
432
433### Fixed
434- Eliminated duplicate accelerator triggers via debouncing.
435- Corrected asset resolution and URL normalization in scheme handler.
