6
7## [0.13.0] - 2025-10-24
8
9### Added
10- **Color scheme config**: `appearance.color_scheme` setting to force dark/light theme (`"prefer-dark"`, `"prefer-light"`, `"default"`)
11- **DNS prefetch**: Added capability to prefetch DNS for links to speed up future requests
12- **Page cache (bfcache)**: Enabled WebKit back/forward cache for instant navigation
13- **Smooth scrolling**: Enabled WebKit smooth scrolling for better UX
14- **JSON Schema**: Auto-generated config schema for IDE autocompletion and validation
15- **Parallel cache loading**: Zoom, certificate, and fuzzy caches load concurrently at startup (<100ms target)
16- **Certificate validation cache**: In-memory cache for TLS certificate decisions with graceful shutdown flushing
17
18### Changed
19- **Database performance**: Enabled WAL mode with optimized PRAGMAs (64MB cache, memory-mapped I/O, 5s busy timeout) for 70k reads/sec, 3.6k writes/sec
20- **Zoom performance**: In-memory cache eliminates database reads during page transitions
21- **History writes**: Batched writes with background processor (flush every 5s or 50 items) to reduce I/O overhead
22- **BREAKING: Keyboard shortcuts**: All shortcuts now use `ctrl+` instead of `cmdorctrl+`. Existing configs with `cmdorctrl` still work via backward compatibility. Delete `~/.config/dumber/config.json` to regenerate with new defaults.
23- **Cache management**: Graceful cache flushing on shutdown prevents data loss; startup timing instrumentation with performance warnings
24
25### Fixed
26- **Graceful shutdown deadlock**: Resolved GTK main loop deadlock on Ctrl+Q by removing mutex locks and GTK calls after main loop exit
27- **CSS provider error handling**: Now properly handles errors from GTK CSS provider with logging
28- **Cache operations**: Added context timeouts to cache flush and history queue operations for graceful failure
29- Command typos now show proper error instead of opening in browser
30- History queue now uses buffered channel to prevent blocking on shutdown
31
32## [0.12.1] - 2025-10-18
33
34### Added
35- **Favicon refactoring**: WebKitGTK FaviconDatabase as single source of truth, removing fragile file-based cache and ico/bmp conversion dependencies
36  - Native favicon detection and automatic PNG export at 32x32 for CLI (dmenu)
37  - SVG favicon rasterization support
38  - Async texture loading with callbacks for non-blocking UI updates
39  - FaviconService handles favicon collection across all panes
40
41### Changed
42- Removed old favicon cache system (go-ico, go-bmp dependencies)
43- Simplified omnibox favicon handling: uses database favicon_url only
44
45### Fixed
46- Mouse button navigation: Added support for hardware mouse buttons 8/9 (back/forward)
47- Touchpad gestures: Two-finger horizontal swipe for back/forward navigation
48- Web app shortcuts: Ctrl+C, Ctrl+V, Ctrl+A now work in Gmail, VSCode web, etc.
49- Dark mode flash on startup: Set GTK dark theme preference and WebView background color before window/content creation
50- Cmd+Q and window close button now trigger graceful shutdown instead of killing the browser process
51- WebView cleanup: Properly destroy WebViews to prevent memory leaks and duplicate handler registrations when closing stacked panes
52- CLI help: Running `dumber` without arguments now shows available commands (use `--gui` or `browse` to launch GUI)
53
54## [0.12.0] - 2025-10-16
55
56### Added
57- **Native favicon support**: WebKit FaviconDatabase integration with automatic detection and caching for all panes
58- ENV=dev support to isolate test builds from production config/data in .dev/dumber/ directory
59- Content filtering whitelist config (Twitch enabled by default)
60- `dumber config` command to open config file in $VISUAL/$EDITOR or print path with `--path`
61- **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
62- **Popup behavior configuration**: Added `popup_behavior` config with four modes: `split` (default), `stacked`, `tabbed`, and `windowed` for user control over popup placement
63- **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.
64- **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
65
66### Changed
67- **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
68- **GUI bootstrap refactoring**: Extracted 400+ lines of common initialization logic into reusable bootstrap.ts module shared between injected pages and special schemes (homepage, etc.)
69- **Workspace pane mode**: Moved ~450 lines of JavaScript state machine to Go backend for more reliable keyboard handling and eliminated race conditions between webviews
70
71### Fixed
72- **TLS certificate validation restored**: Re-implemented persistent certificate error handling (broken during gotk4 migration)
73  - Interactive three-option dialog: "Go Back", "Proceed Once (Unsafe)", and "Always Accept This Site"
74  - SQLite-based hostname decision storage (hostname-only matching - GIO certificate properties are unstable)
75  - Smart expiration: "Proceed Once" temporary (not stored), "Always Accept" persists for 30 days
76  - Automatic cleanup of expired validations on application startup
77  - **Known issue**: Accepted certificates not pre-loaded into WebKit session on startup - stored decisions only apply when TLS error occurs again
78- **Content blocking restored**: Re-implemented WebKit native ad/tracker blocking (broken during gotk4 migration) using UserContentFilterStore API
79- **Script injection spam**: Fixed 100+ duplicate "Sending color palettes" messages by injecting scripts only in top frame instead of all iframes
80- **Favicon race conditions**: Eliminated duplicate downloads and file handle errors via mutex protection and proper handler registration
81- **Homepage theme switching**: Fixed color palette application for proper light/dark mode transitions
82- **Workspace pane borders**: Hide active pane border when only one pane exists to match Zellij UX
83- Enabled missing WebKitGTK6 features: WebRTC, MediaSource, LocalStorage, WebAudio, MediaStream, Clipboard
84- Cosmetic filter duplicate injection in frames
85- Config file duplicate keys (snake_case/camelCase) by using Viper's SafeWriteConfigAs
86- Config not reading newly created default config file
87- Config writing to disk on every load/reload
88- **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
89- **GTK focus event duplicates**: Added timestamp-based deduplication to prevent multiple focus enter/leave events in the same millisecond from WebKitGTK nested widgets
90- **Popup close behavior**: Fixed app exit when closing popups by excluding them from remaining pane count check
91- **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
92- **Stacked pane active border**: Fixed active border incorrectly appearing on stacked pane containers instead of individual panes
93- **Stacked pane creation**: Fixed premature Realize() call causing widget lifecycle issues during stack creation
94- **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
95- **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
96
97## [0.11.0] - 2025-10-07
98
99### Added
100- **Auto-open omnibox on blank panes**: Omnibox automatically opens when a new pane is created with about:blank, providing immediate search/navigation access
101- **Configurable default zoom**: Added `default_zoom` config (defaults to 1.2/120%). Per-domain zoom still overrides this
102- **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
103- **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
104- **Stacked pane favicons**: Title bars display site favicons with async caching. Click title bars to switch between stacked panes
105- **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
106- **Search shortcut badges**: Visual badges in omnibox input showing active shortcut prefix (e.g., "gh:", "npm:") with description labels
107- **Search shortcuts API**: Frontend bridge to fetch search shortcuts from backend `/api/config` endpoint with automatic normalization
108
109### Changed
110- **Terminal-style UI theme**: Monospace fonts (JetBrains Mono, Fira Code), sharp corners (no border-radius), dashed borders, adjusted shadows and spacing throughout omnibox components
111- **History suggestions**: Use favicon from database when available, omit automatic search shortcuts from suggestions (rely on explicit prefix commands)
112- **Search shortcuts defaults**: Updated defaults to include ddg, go, mdn, npm packages while reordering others
113- **Chrome user agent**: Updated to version 141.0.0.0 for better site compatibility
114- **CSS color system**: Removed hardcoded theme colors, now use dynamic CSS custom properties from Go-injected palette
115- **History item layout**: Removed "• domain" from titles, now highlight domain within the full URL using same color as title text
116- **Quick access logic**: Removed 20-item limit, now shows all sites with 2+ visits (pinned sites bypass visit requirement)
117- **History pagination**: Show 15 items initially (up from 10) with "Show N more" button
118- **Homepage layout**: Redesigned with improved visual hierarchy and dynamic color tokens
119- **Favicon handlers**: All webviews now register favicon change handlers for consistent caching across panes
120
121### Fixed
122- **Mobile URL overflow**: Fixed long URLs breaking layout on narrow screens by adding proper width constraints and CSS fixes

130- **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
131
132## [0.10.0] - 2025-09-24
133
134### Added

144- **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
145- **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
146- **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
147- **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
148- **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
149- **Workspace architecture**: Simplified focus tracking by removing URI change handlers and pane ID injection complexity, improving reliability and reducing codebase by 85 lines
150- **WebView ID propagation**: Added webview ID request/response mechanism for stub builds to ensure JavaScript side knows its webview ID for proper focus validation

152- **GTK window background**: Added theme-aware window and pane background colors to prevent white bleeding through transparent elements
153- **Print dialog window handling**: Fixed GTK window destroy errors during WebView cleanup by only destroying windows when CreateWindow was actually enabled
154- **Modifier key logging noise**: Filtered out Ctrl, Shift, Alt, and Super key presses from accelerator miss logging to reduce console spam
155
156## [0.9.0] - 2025-09-22
157
158### Added
159- **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)

169- **WebView identity tracking**: Unique WebView ID system for precise popup targeting and enhanced debugging capabilities
170
171### Improved
172- WebKit integration now forces GPU compositing by default while still honoring explicit config overrides.
173- Smooth scrolling is enabled (when supported) so wheel and gesture animations feel closer to Chromium/Firefox.
174- 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.
175- Added optional DOM-level zoom (enabled by default) to avoid native viewport rescaling; falls back to WebKit zoom if the CSS path fails.
176- 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%.
177- Native accelerator bridge debounces duplicate GTK key events earlier, so Ctrl±/Ctrl+0 only fires once per physical key press.
178- Omnibox-triggered navigations now reuse the navigation controller, so saved zoom levels are applied before first paint and redundant lookups are avoided.
179- Configuration loading writes the missing `use_dom_zoom` flag into existing config files so DOM zoom defaults persist without manual edits.
180- Omnibox UI now relies on shared Tailwind theme tokens and the injected color-scheme service for light/dark parity.
181- Omnibox overlay now self-heals if hostile pages remove the injected shadow host, ensuring Ctrl/Cmd+L works everywhere.

414
415## [0.3.0] - 2025-01-11
416
417### Added
418- WebKit memory controls (opt‑in):
419  - Env vars to tune memory/perf trade‑offs without code changes:
420    - `DUMBER_CACHE_MODEL`, `DUMBER_ENABLE_PAGE_CACHE`
421    - `DUMBER_ENABLE_MEMORY_MONITORING`, `DUMBER_MEMORY_LIMIT_MB`, `DUMBER_MEMORY_POLL_INTERVAL`
422    - `DUMBER_MEMORY_CONSERVATIVE`, `DUMBER_MEMORY_STRICT`, `DUMBER_MEMORY_KILL`
423    - `DUMBER_GC_INTERVAL`, `DUMBER_RECYCLE_THRESHOLD`
424  - Version‑guarded CGO wrappers for memory pressure and GC hooks; safe no‑ops on unsupported WebKitGTK builds.
425 - Find in page (Ctrl/Cmd+F):
426   - Omnibox refactored into a reusable component with dedicated "find" mode.
427   - Highlighting: yellow for all matches; active match in orange for clarity.
428   - Match list with context (right side stops at nearest punctuation: . , ; : -).
429   - Navigation UX:
430     - ArrowUp/Down move selection and scroll the overlay list (page scroll disabled while open).
431     - Enter centers on the active match and closes; Shift+Enter goes to previous; Alt+Enter centers without closing.
432     - Hover focuses input and selects list items; click outside closes the overlay.
433     - Faded overlay with subtle blur when reviewing matches; opacity restores on input focus/typing.
434   - Programmatic API: `OpenFind(initial)`, `FindQuery(q)`, `CloseFind()` on `WebView`.
435
436### Changed
437- Performance‑first defaults retained:
438  - Cache model set to “WebBrowser”, page cache enabled, DevTools available.
439  - No implicit memory pressure or GC enabled by default; all memory tuning is opt‑in.
440
441### Removed
442- Deprecated offline app‑cache calls eliminated (no‑ops) to avoid warnings and brittle builds.
443
444### Fixed
445- Homepage Recent History layout:
446  - Show single-line entries as “{Title} – {Domain} – {URL}”.
447  - Truncate long URLs with a gradient fade; prevent horizontal overflow.
448  - Adjusted styling so URL is darker for readability.
449- Search shortcuts and config interop:
450  - Backend SearchShortcut now serializes `url`/`description` with JSON tags.
451  - Frontend normalizes field casing and extracts base URLs, handling `%s` and `{query}` templates.
452  - Omnibox shortcut parsing now URL-encodes queries and supports `%s` placeholders.
453- Input and navigation reliability (GTK4/WebKitGTK 6):
454  - Capture-phase key controller to ensure accelerators fire consistently.
455  - Do not consume normal left/right clicks; only mouse buttons 8/9 trigger back/forward.
456  - Added Alt+ArrowLeft/Right navigation and enabled two-finger swipe back/forward when supported.
457  - Added Ctrl+scroll zoom in/out; refined accelerator matching so Ctrl− works across layouts.
458  - Removed layout-specific hacks; added diagnostic logs for raw minus key events.
459- Zoom persistence:
460  - Added WebView zoom-changed hook; save per-domain zoom to SQLite on every change.
461  - Log on successful save: “saved X.XX for domain.tld” and on load: “loaded X.XX for domain.tld”.
462  - Load and log initial zoom level on startup and on every navigation.
463- Build/dev ergonomics:
464  - Makefile loads `.env.local`; supports overriding `GOMODCACHE`, `GOCACHE`, `GOTMPDIR` for sandboxed builds.
465 - WebKit CGO hardening and API compatibility:
466   - Apply memory pressure settings to `WebKitNetworkSession` (correct signature) when enabled.
467   - Guarded C wrappers remove deprecation warnings across header variants; builds succeed on WebKitGTK 6.
468
469## [0.2.0] - 2025-09-10
470
471### Added
472- WebKitGTK 6 (GTK4) migration for the built‑in browser window:
473  - WebView constructed via `g_object_new(WEBKIT_TYPE_WEB_VIEW, …)` with a fresh `WebKitUserContentManager`.
474  - `WebKitNetworkSession` with persistent cookies (SQLite) and cache directories.
475- Native UCM messaging restored via `script-message-received::dumber` (JSCValue*), removing the JS fallback bridge.
476- Rendering mode controls:
477  - CLI flag `--rendering-mode=auto|gpu|cpu` and `DUMBER_RENDERING_MODE` env.
478  - In‑app status endpoint `dumb://homepage/api/rendering/status`.
479- Native zoom shortcuts at the WebKit layer (Ctrl/Cmd+=, +, −, 0) and GTK4 input controllers for keyboard/mouse.
480- AZERTY keyboard fix: treat underscore as minus for zoom‑out.
481- Runtime theme synchronization: watch GTK `gtk-application-prefer-dark-theme` and update page color‑scheme live.
482- Makefile target `check-webkit` to print `pkg-config` versions of GTK4/WebKitGTK 6.0/JSC 6.0.
483- Documentation updates:
484  - README now targets WebKitGTK 6 (GTK4) and lists GStreamer package requirements for Arch and Debian/Ubuntu.
485  - CLAUDE notes updated with migration status, GPU/Vulkan path, runtime theme sync, and persistence.
486
487### Changed
488- Build flags and includes now target `webkitgtk-6.0`, `gtk4`, and `javascriptcoregtk-6.0`.
489- GTK4 APIs for windowing and event handling (GtkEventController, GtkGestureClick) replace GTK3/GdkEvent paths.
490
491### Removed
492- Legacy WebKit2GTK constructors and container APIs.
493- JavaScript fallback for UCM message bridging.
494
495### Fixed
496- Header/enum compatibility for hardware acceleration policy and cookie policy across WebKit header variants.
497- Linker error for `on_theme_changed` and gpointer usage in signal connections.
498- Crashy paths mitigated by default “media safe” startup (can be disabled via `DUMBER_MEDIA_SAFE=0`).
499
500### Notes
501- GPU rendering path leverages GTK4’s renderer (Vulkan/OpenGL). Mode `auto` uses GPU when available and falls back gracefully to CPU.
502- WebKitGTK relies on GStreamer; install recommended packages for audio/video (see README).
503
