6
7## [0.12.0] - 2025-10-16
8
9### Added
10- **Native favicon support**: WebKit FaviconDatabase integration with automatic detection and caching for all panes
11- ENV=dev support to isolate test builds from production config/data in .dev/dumber/ directory
12- Content filtering whitelist config (Twitch enabled by default)
13- `dumber config` command to open config file in $VISUAL/$EDITOR or print path with `--path`
14- **Native WebKit popup lifecycle**: Implemented WebKit's create/ready-to-show/close signals for proper popup management, eliminating manual WebView creation that bypassed WebKit's internal architecture
15- **Popup behavior configuration**: Added `popup_behavior` config with four modes: `split` (default), `stacked`, `tabbed`, and `windowed` for user control over popup placement
16- **Backend-driven pane mode**: Complete rewrite of pane mode from JavaScript to Go backend with native keyboard handling. Ctrl+P enters mode, x/l/r/d/u/arrows for actions, Escape exits. Blocks all other keys during mode.
17- **Pane mode visual border**: Zellij-style border around workspace root when pane mode is active, replacing old toast notification system. Uses GTK margins with configurable `pane_mode_border_color` (defaults to #FFA500 orange). Window background color shows through margins to create visible border effect
18
19### Changed
20- **Popup architecture refactoring**: Removed ~280 lines of JavaScript window.open interception in favor of WebKit's native popup signals. Popups now follow WebKitGTK's expected lifecycle instead of being intercepted and manually created
21- **GUI bootstrap refactoring**: Extracted 400+ lines of common initialization logic into reusable bootstrap.ts module shared between injected pages and special schemes (homepage, etc.)
22- **Workspace pane mode**: Moved ~450 lines of JavaScript state machine to Go backend for more reliable keyboard handling and eliminated race conditions between webviews
23
24### Fixed
25- **TLS certificate validation restored**: Re-implemented persistent certificate error handling (broken during gotk4 migration)
26  - Interactive three-option dialog: "Go Back", "Proceed Once (Unsafe)", and "Always Accept This Site"
27  - SQLite-based hostname decision storage (hostname-only matching - GIO certificate properties are unstable)
28  - Smart expiration: "Proceed Once" temporary (not stored), "Always Accept" persists for 30 days
29  - Automatic cleanup of expired validations on application startup
30  - **Known issue**: Accepted certificates not pre-loaded into WebKit session on startup - stored decisions only apply when TLS error occurs again
31- **Content blocking restored**: Re-implemented WebKit native ad/tracker blocking (broken during gotk4 migration) using UserContentFilterStore API
32- **Script injection spam**: Fixed 100+ duplicate "Sending color palettes" messages by injecting scripts only in top frame instead of all iframes
33- **Favicon race conditions**: Eliminated duplicate downloads and file handle errors via mutex protection and proper handler registration
34- **Homepage theme switching**: Fixed color palette application for proper light/dark mode transitions
35- **Workspace pane borders**: Hide active pane border when only one pane exists to match Zellij UX
36- Enabled missing WebKitGTK6 features: WebRTC, MediaSource, LocalStorage, WebAudio, MediaStream, Clipboard
37- Cosmetic filter duplicate injection in frames
38- Config file duplicate keys (snake_case/camelCase) by using Viper's SafeWriteConfigAs
39- Config not reading newly created default config file
40- Config writing to disk on every load/reload
41- **Popup SIGSEGV crashes**: Eliminated segmentation violations during popup lifecycle by respecting WebKit's signal-based popup management. Fixes OAuth popup crashes and GTK bloom filter corruption
42- **GTK focus event duplicates**: Added timestamp-based deduplication to prevent multiple focus enter/leave events in the same millisecond from WebKitGTK nested widgets
43- **Popup close behavior**: Fixed app exit when closing popups by excluding them from remaining pane count check
44- **Pane mode border cleanup**: Fixed border persisting after pane splits by saving container reference when applying margins. Ensures proper cleanup even when workspace tree structure changes during split operations
45- **Stacked pane active border**: Fixed active border incorrectly appearing on stacked pane containers instead of individual panes
46- **Stacked pane creation**: Fixed premature Realize() call causing widget lifecycle issues during stack creation
47- **Browser exit on last pane close**: Fixed browser not properly quitting when closing the last webview via Ctrl+P x by calling GTK main loop quit instead of window close
48- **Zoom level persistence restored**: Fixed per-domain zoom settings not being saved to database (broken during gotk4 migration). Added missing `notify::zoom-level` signal connection in setupEventHandlers to properly persist zoom changes
49
50## [0.11.0] - 2025-10-07
51
52### Added
53- **Auto-open omnibox on blank panes**: Omnibox automatically opens when a new pane is created with about:blank, providing immediate search/navigation access
54- **Configurable default zoom**: Added `default_zoom` config (defaults to 1.2/120%). Per-domain zoom still overrides this
55- **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
56- **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
57- **Stacked pane favicons**: Title bars display site favicons with async caching. Click title bars to switch between stacked panes
58- **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
59- **Search shortcut badges**: Visual badges in omnibox input showing active shortcut prefix (e.g., "gh:", "npm:") with description labels
60- **Search shortcuts API**: Frontend bridge to fetch search shortcuts from backend `/api/config` endpoint with automatic normalization
61
62### Changed
63- **Terminal-style UI theme**: Monospace fonts (JetBrains Mono, Fira Code), sharp corners (no border-radius), dashed borders, adjusted shadows and spacing throughout omnibox components
64- **History suggestions**: Use favicon from database when available, omit automatic search shortcuts from suggestions (rely on explicit prefix commands)
65- **Search shortcuts defaults**: Updated defaults to include ddg, go, mdn, npm packages while reordering others
66- **Chrome user agent**: Updated to version 141.0.0.0 for better site compatibility
67- **CSS color system**: Removed hardcoded theme colors, now use dynamic CSS custom properties from Go-injected palette
68- **History item layout**: Removed "• domain" from titles, now highlight domain within the full URL using same color as title text
69- **Quick access logic**: Removed 20-item limit, now shows all sites with 2+ visits (pinned sites bypass visit requirement)
70- **History pagination**: Show 15 items initially (up from 10) with "Show N more" button
71- **Homepage layout**: Redesigned with improved visual hierarchy and dynamic color tokens
72- **Favicon handlers**: All webviews now register favicon change handlers for consistent caching across panes
73
74### Fixed

76- **GTK shortcut GLib-CRITICAL error**: Fixed NULL string assertion in shortcut callback system
77- **SVG favicon handling**: Skip SVG favicons to prevent conversion errors (no raster conversion dependencies)
78- **Focus management architecture**: Refactored workspace focus system from `active` field to `currentlyFocused` with dedicated FocusManager for improved reliability and consistency across pane operations
79- **Stacked pane focus conflicts**: Fixed focus stealing issues in stacked panes by implementing focus-aware navigation that preserves active pane when spawning siblings
80- **WebView title updates**: Enhanced webview title change handling to properly update stacked pane title bars in addition to database storage
81- **GTK4 widget lifecycle**: Improved widget parenting/unparenting operations with proper GTK4 validation and automatic cleanup to prevent critical warnings
82- **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
83- **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
84
85## [0.10.0] - 2025-09-24
86
87### Added
88- **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
89- **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
90
91### Changed
92- **Homepage redesign**: Brutal design with component-scoped styling, dynamic height matching, inline domain-URL layout with fade effects, and tighter spacing
93
94### Fixed

97- **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
98- **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
99- **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
100- **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
101- **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
102- **Workspace architecture**: Simplified focus tracking by removing URI change handlers and pane ID injection complexity, improving reliability and reducing codebase by 85 lines
103- **WebView ID propagation**: Added webview ID request/response mechanism for stub builds to ensure JavaScript side knows its webview ID for proper focus validation

105- **GTK window background**: Added theme-aware window and pane background colors to prevent white bleeding through transparent elements
106- **Print dialog window handling**: Fixed GTK window destroy errors during WebView cleanup by only destroying windows when CreateWindow was actually enabled
107- **Modifier key logging noise**: Filtered out Ctrl, Shift, Alt, and Super key presses from accelerator miss logging to reduce console spam
108
109## [0.9.0] - 2025-09-22
110
111### Added
112- **Zellij-style workspace management**: Complete pane splitting system with binary tree layout, focus tracking, and Zellij-inspired keybindings (Ctrl+P for pane mode, arrow keys for splits, 'x' to close)

114- **Window-level global shortcuts**: Centralized shortcut handling to prevent conflicts between multiple WebView instances
115- **Workspace configuration**: New config section with Zellij controls toggle, pane mode bindings, tab shortcuts, and popup behavior settings
116- **Configurable workspace styling**: Pane border appearance (width, color, transition duration, radius) now customizable via config with proper viewport stability
117- **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
118- **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
119- **Advanced popup deduplication system**: Intelligent duplicate popup prevention with SHA256 fingerprinting and 200ms debounce window to eliminate popup spam

123
124### Improved
125- WebKit integration now forces GPU compositing by default while still honoring explicit config overrides.
126- Smooth scrolling is enabled (when supported) so wheel and gesture animations feel closer to Chromium/Firefox.
127- 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.
128- Added optional DOM-level zoom (enabled by default) to avoid native viewport rescaling; falls back to WebKit zoom if the CSS path fails.
129- 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%.
130- Native accelerator bridge debounces duplicate GTK key events earlier, so Ctrl±/Ctrl+0 only fires once per physical key press.
131- Omnibox-triggered navigations now reuse the navigation controller, so saved zoom levels are applied before first paint and redundant lookups are avoided.
132- Configuration loading writes the missing `use_dom_zoom` flag into existing config files so DOM zoom defaults persist without manual edits.
133- Omnibox UI now relies on shared Tailwind theme tokens and the injected color-scheme service for light/dark parity.
134- Omnibox overlay now self-heals if hostile pages remove the injected shadow host, ensuring Ctrl/Cmd+L works everywhere.

323  - Anti-aliasing preservation during color inversion to prevent edge noise and pixelation
324  - Asynchronous favicon downloading and caching with 7-day freshness and 30-day cleanup
325  - Fuzzel icon protocol integration (`\0icon\x1f<path>`) for native icon display
326  - Favicon URLs extracted from webpage metadata and stored in database during navigation
327  - Fallback system removed to ensure consistent sizing - shows real favicons or no icon
328  - XDG Base Directory compliance for favicon cache storage
329
330## [0.4.0] - 2025-09-10
331
332### Added
333- High-performance fuzzy cache system for dmenu history:
334  - Binary serialization with memory-mapped files for zero-copy access
335  - Trigram indexing (3-character sequences) for fast candidate filtering  
336  - Prefix trie (compressed tree structure) for prefix matching
337  - Pre-sorted entry indices for O(1) top entries retrieval
338  - Smart cache invalidation with filesystem persistence and background refresh
339  - Comprehensive fuzzy matching algorithms: Jaro-Winkler similarity, Levenshtein distance, tokenized matching
340  - Weighted scoring system combining URL, title, recency, and visit count scores
341  - XDG Base Directory Specification compliance (cache stored in state directory)
342  - Atomic operations for concurrent access control
343  - Dependency injection using interfaces and gomock for testing
344- Purge command for cleaning up dumber data and cache files:
345  - Selective purging with flags: `--database`, `--history-cache`, `--browser-cache`, `--browser-data`, `--state`, `--config`
346  - Clear distinction between history cache (dmenu fuzzy search) and browser cache (WebKit)
347  - Browser data includes cookies, localStorage, sessionStorage
348  - Confirmation prompt with `--force` flag to skip
349  - Targets all data locations: SQLite database, WebKit cache/data, dmenu fuzzy cache, configuration files
350- Ctrl+Shift+C keyboard shortcut to copy current URL to clipboard:
351  - Cross-platform clipboard support with wl-copy (Wayland) and xclip (X11) fallback
352  - Reusable toast notification system for user feedback
353  - Injectable JavaScript component for consistent styling across all websites
354  - Native backend integration for reliable clipboard access
355
356### Changed
357- Dmenu performance dramatically improved: 200ms → 4ms (98% faster)
358- GetTopEntries optimized from O(n log n) to O(1) using pre-sorted indices
359- Cache build time reduced to ~300μs for typical history datasets
360
361### Fixed
362- Dark theme detection now properly reads GNOME desktop interface color-scheme setting (`org.gnome.desktop.interface color-scheme`) instead of only checking `gtk-application-prefer-dark-theme`
363- Eliminated O(n log n) sorting bottleneck on every dmenu call
364- Memory-efficient compact entry storage with minimal footprint
365- Concurrent cache access with proper read/write locking
366- Process no longer hangs when closing window with Cmd+Q or window close button - implemented proper GTK4 `close-request` signal handling and OS signal handling for graceful shutdown
367
368## [0.3.0] - 2025-01-11
369
370### Added
371- WebKit memory controls (opt‑in):
372  - Env vars to tune memory/perf trade‑offs without code changes:
373    - `DUMBER_CACHE_MODEL`, `DUMBER_ENABLE_PAGE_CACHE`
374    - `DUMBER_ENABLE_MEMORY_MONITORING`, `DUMBER_MEMORY_LIMIT_MB`, `DUMBER_MEMORY_POLL_INTERVAL`
375    - `DUMBER_MEMORY_CONSERVATIVE`, `DUMBER_MEMORY_STRICT`, `DUMBER_MEMORY_KILL`
376    - `DUMBER_GC_INTERVAL`, `DUMBER_RECYCLE_THRESHOLD`
377  - Version‑guarded CGO wrappers for memory pressure and GC hooks; safe no‑ops on unsupported WebKitGTK builds.
378 - Find in page (Ctrl/Cmd+F):
379   - Omnibox refactored into a reusable component with dedicated "find" mode.
380   - Highlighting: yellow for all matches; active match in orange for clarity.
381   - Match list with context (right side stops at nearest punctuation: . , ; : -).
382   - Navigation UX:
383     - ArrowUp/Down move selection and scroll the overlay list (page scroll disabled while open).
384     - Enter centers on the active match and closes; Shift+Enter goes to previous; Alt+Enter centers without closing.
385     - Hover focuses input and selects list items; click outside closes the overlay.
386     - Faded overlay with subtle blur when reviewing matches; opacity restores on input focus/typing.
387   - Programmatic API: `OpenFind(initial)`, `FindQuery(q)`, `CloseFind()` on `WebView`.
388
389### Changed
390- Performance‑first defaults retained:
391  - Cache model set to “WebBrowser”, page cache enabled, DevTools available.
392  - No implicit memory pressure or GC enabled by default; all memory tuning is opt‑in.
393
394### Removed
395- Deprecated offline app‑cache calls eliminated (no‑ops) to avoid warnings and brittle builds.
396
397### Fixed
398- Homepage Recent History layout:
399  - Show single-line entries as “{Title} – {Domain} – {URL}”.
400  - Truncate long URLs with a gradient fade; prevent horizontal overflow.
401  - Adjusted styling so URL is darker for readability.
402- Search shortcuts and config interop:
403  - Backend SearchShortcut now serializes `url`/`description` with JSON tags.
404  - Frontend normalizes field casing and extracts base URLs, handling `%s` and `{query}` templates.
405  - Omnibox shortcut parsing now URL-encodes queries and supports `%s` placeholders.
406- Input and navigation reliability (GTK4/WebKitGTK 6):
407  - Capture-phase key controller to ensure accelerators fire consistently.
408  - Do not consume normal left/right clicks; only mouse buttons 8/9 trigger back/forward.
409  - Added Alt+ArrowLeft/Right navigation and enabled two-finger swipe back/forward when supported.
410  - Added Ctrl+scroll zoom in/out; refined accelerator matching so Ctrl− works across layouts.
411  - Removed layout-specific hacks; added diagnostic logs for raw minus key events.
412- Zoom persistence:
413  - Added WebView zoom-changed hook; save per-domain zoom to SQLite on every change.
414  - Log on successful save: “saved X.XX for domain.tld” and on load: “loaded X.XX for domain.tld”.
415  - Load and log initial zoom level on startup and on every navigation.
416- Build/dev ergonomics:
417  - Makefile loads `.env.local`; supports overriding `GOMODCACHE`, `GOCACHE`, `GOTMPDIR` for sandboxed builds.
418 - WebKit CGO hardening and API compatibility:
419   - Apply memory pressure settings to `WebKitNetworkSession` (correct signature) when enabled.
420   - Guarded C wrappers remove deprecation warnings across header variants; builds succeed on WebKitGTK 6.
421
422## [0.2.0] - 2025-09-10
423
424### Added
425- WebKitGTK 6 (GTK4) migration for the built‑in browser window:
426  - WebView constructed via `g_object_new(WEBKIT_TYPE_WEB_VIEW, …)` with a fresh `WebKitUserContentManager`.
427  - `WebKitNetworkSession` with persistent cookies (SQLite) and cache directories.
428- Native UCM messaging restored via `script-message-received::dumber` (JSCValue*), removing the JS fallback bridge.
429- Rendering mode controls:
430  - CLI flag `--rendering-mode=auto|gpu|cpu` and `DUMBER_RENDERING_MODE` env.
431  - In‑app status endpoint `dumb://homepage/api/rendering/status`.
432- Native zoom shortcuts at the WebKit layer (Ctrl/Cmd+=, +, −, 0) and GTK4 input controllers for keyboard/mouse.
433- AZERTY keyboard fix: treat underscore as minus for zoom‑out.
434- Runtime theme synchronization: watch GTK `gtk-application-prefer-dark-theme` and update page color‑scheme live.
435- Makefile target `check-webkit` to print `pkg-config` versions of GTK4/WebKitGTK 6.0/JSC 6.0.
436- Documentation updates:
437  - README now targets WebKitGTK 6 (GTK4) and lists GStreamer package requirements for Arch and Debian/Ubuntu.
438  - CLAUDE notes updated with migration status, GPU/Vulkan path, runtime theme sync, and persistence.
439
440### Changed
441- Build flags and includes now target `webkitgtk-6.0`, `gtk4`, and `javascriptcoregtk-6.0`.
442- GTK4 APIs for windowing and event handling (GtkEventController, GtkGestureClick) replace GTK3/GdkEvent paths.
443
444### Removed
445- Legacy WebKit2GTK constructors and container APIs.
446- JavaScript fallback for UCM message bridging.
447
448### Fixed
449- Header/enum compatibility for hardware acceleration policy and cookie policy across WebKit header variants.
450- Linker error for `on_theme_changed` and gpointer usage in signal connections.
451- Crashy paths mitigated by default “media safe” startup (can be disabled via `DUMBER_MEDIA_SAFE=0`).
452
453### Notes
454- GPU rendering path leverages GTK4’s renderer (Vulkan/OpenGL). Mode `auto` uses GPU when available and falls back gracefully to CPU.
455- WebKitGTK relies on GStreamer; install recommended packages for audio/video (see README).
456
457## [0.1.0] - 2025-09-09
458
459### Added
460- Initial project scaffolding, build system, and dependencies.
461- Unified CLI + GUI architecture with search shortcuts and fuzzy parsing.
462- Wails v3‑alpha browser integration (early phase).
463- Global keyboard controls with script injection (zoom/devtools, etc.).
464- Native WebKit2GTK backend migration:
465  - Custom `dumb://` scheme and `/api` endpoints: `/config`, `/history/recent`, `/history/search`, `/history/stats`.
466  - UserContentManager omnibox injection and theme initialization.
467  - Persistent WebsiteDataManager with cookies.sqlite; per‑domain zoom and title persistence.
468  - Keyboard/mouse accelerators (including mouse back/forward); debounced triggers.
469  - Homepage switched to first‑party API fetches; removed @wailsio/runtime usage.
470- Documentation and licensing: README enhancements and LICENSE added.
471
472### Changed
473- Replaced Wails runtime with native WebKit2GTK CGO bindings and homepage API.
474- Improved asset resolution and logging for the `dumb://homepage` scheme.
475
476### Fixed
477- Eliminated duplicate accelerator triggers via debouncing.
478- Corrected asset resolution and URL normalization in scheme handler.
