7## [0.21.0] - 2025-12-26
8
9### Added
10- **Configurable new-pane defaults**: New `workspace.new_pane_url` (default: `about:blank`, supports `dumb://`) and `omnibox.auto_open_on_new_pane` (default: false).
11- **Consume-or-expel panes (very alpha)**: Niri-style pane consume/expel operation to merge a leaf into a sibling stack or expel a stacked pane into a split. Default global shortcuts: `Alt+[` / `Alt+]` (and `Alt+Shift+[` / `Alt+Shift+]`).
12- **Zellij-style pane resize mode**: New modal resize mode (`Ctrl+N`) to adjust split sizes with keyboard (`h/j/k/l` or arrow keys, `+/-` smart resize). Shows a per-pane border indicator and keeps the timeout alive while you resize.
13- **Mouse-driven pane resizing**: Drag split dividers with the mouse; split ratios are persisted in session snapshots (rounded to 2 decimals) and restored on resurrection.
14- **Dynamic window title**: Window title now displays the active pane's page title in format `<Page Title> - Dumber`. Updates when switching tabs/panes or navigating. Truncated at 255 characters.
15- **Link URL status overlay**: Shows destination URL in bottom-left corner when hovering over links, images, or media elements. Standard browser UX pattern with 100ms show delay to avoid flicker and 150ms CSS fade transitions. Configurable via CSS.
16- **Local file path support**: `dumber browse test.html` now correctly opens local HTML files by converting existing file paths to `file://` URLs. Supports absolute paths, relative paths, and `~/` home directory expansion.
17- **Auto-update system**: Automatic update checking and self-updating binary replacement following clean architecture.
18  - **Update check on startup**: Async check against GitHub releases API (configurable via `update.enable_on_startup`, default: true).
19  - **Toast notifications**: Non-intrusive auto-dismiss notifications for update availability.
20  - **Auto-download**: Optional background download with binary staging (configurable via `update.auto_download`, default: false).
21  - **Binary self-update**: Atomic binary replacement on clean exit with `.old` backup. Only works if binary is user-writable (e.g., `~/.local/bin/`).
22  - **CLI update check**: `dumber about` now displays update availability.
23  - **Version-less release archives**: Goreleaser now produces `dumber_linux_x86_64.tar.gz` (version in directory inside) enabling stable GitHub `/releases/latest/download/` URLs.
24- **Session management & resurrection**: Zellij-inspired session management system allowing users to save, list, and restore browser sessions.
25  - **Automatic session snapshots**: Debounced state saving (configurable interval, default 5s) captures tabs, panes, splits, stacks, URLs, titles, and zoom levels.
26  - **Session Manager modal**: Access via `Ctrl+O → s/w` or `Ctrl+Shift+S` to browse and restore sessions with inline preview of tabs and panes.
27  - **Session mode**: New modal mode (`Ctrl+O`) with purple border indicator, similar to pane/tab modes.
28  - **CLI session commands**: `dumber sessions` opens interactive TUI browser; `dumber sessions list` shows saved sessions; `dumber sessions restore <id>` resurrects a session in a new window; `dumber sessions delete <id>` removes a session.
29  - **Session purging**: Integrated into `dumber purge` command for cleaning up old session data. Simplified UI with single "Sessions" toggle instead of individual selection.
30  - **Automatic session cleanup**: Sessions are automatically cleaned up on startup based on `max_exited_sessions` (default: 50) and `max_exited_session_age_days` (default: 7 days).
31  - **Configuration options**: `session.auto_restore`, `session.snapshot_interval_ms`, `session.max_exited_sessions`, `session.max_exited_session_age_days`, plus session mode shortcuts and styling.

33### Fixed
34- **Alt/Ctrl+number shortcuts on non-QWERTY keyboards**: Fixed Alt+1-9/0 tab switching and Ctrl+1-9/0 omnibox shortcuts not working on AZERTY, QWERTZ, Dvorak, and other non-QWERTY keyboard layouts. Uses hardware keycodes as fallback when keyval lookup fails, enabling shortcuts to work based on physical key position regardless of layout.
35- **Idle inhibition leak on pane close**: Fixed D-Bus idle inhibit request not being released when closing a pane/tab while in fullscreen or playing audio. The inhibition would remain active until the app exited. Now properly tracks fullscreen and audio state and releases inhibition before destroying WebView.
36- **Audio-based idle inhibition**: Extended idle inhibition to also activate when a page is playing audio (e.g., video/music playback), not just in fullscreen mode. Uses WebKit's `notify::is-playing-audio` signal. The inhibitor uses refcounting, so both fullscreen and audio can be active simultaneously.
37
38## [0.20.1] - 2025-12-25
39
40### Fixed
41- **Stacked pane favicon and title updates**: Fixed favicon and title not updating in stacked pane title bars by tracking pane IDs in StackedView and properly routing update events to the correct pane.
42- **WebKit process leak on pane close**: Fixed zombie WebKit web processes not being terminated when panes were closed. `WebView.Destroy()` now properly calls `TerminateWebProcess()` and unparents GTK widgets, freeing GPU resources (VA-API, DMA-BUF, GL contexts). This should significantly improve video playback stability and reduce memory usage when opening/closing many panes.
43- **White flash on navigation**: Eliminated white page flash when navigating in dark mode by setting WebView background color to match theme and hiding WebView until content commits.
44- **Dark mode detection on websites**: Fixed `prefers-color-scheme: dark` detection by improving matchMedia query normalization and adding proper event listener stubs. Sites like Reddit now correctly detect dark mode preference.
45- **Alt+number tab switching**: Fixed Alt+1-9 shortcuts not working when WebView has focus by using GtkShortcutController with global scope instead of EventControllerKey.
46- **System locking during fullscreen video**: Added idle inhibition via XDG Desktop Portal when WebView enters fullscreen mode. Prevents system from locking/sleeping during fullscreen video playback on Wayland (works with all compositors: GNOME, KDE, sway, hyprland, etc.).
47- **Navigation performance**: Significantly faster page navigation through multiple optimizations:
48  - Async history recording via background worker (SQLite writes no longer block GTK main thread)
49  - LRU cache for per-domain zoom levels (repeat visits skip database queries)
50  - Async favicon preload (cache lookup doesn't block navigation start)
51  - Progress callback throttling at ~60fps (reduces UI callback overhead)
52  - Increased WebView pool prewarm from 2 to 4 for faster initial tab creation
53
54### Changed
55- **Custom color picker and confirm dialogs**: Replaced native GTK color picker and confirm dialogs with custom Svelte components using bits-ui AlertDialog. Fixes Wayland compatibility issues where native dialogs would not display properly (fixes #12).
56- **GSK renderer default**: Changed default from `vulkan` to `auto` to let GTK choose the best renderer and avoid potential DMA-BUF synchronization conflicts with WebKit.
57- **Removed invalid GStreamer config**: Removed `video_buffer_size_mb` and `queue_buffer_time_sec` config options as these were not valid GStreamer environment variables (they are element properties that cannot be set via env vars).
58
59### Added
60- **Performance config section**: New `performance` config section with `zoom_cache_size` (default: 256) and `webview_pool_prewarm_count` (default: 4) for tuning. Not exposed in UI but can be set in config file.
61- **Clean-architecture rewrite (pure Go)**: Major refactor to a ports/adapters style architecture with explicit `domain`, `application` (use cases), `infrastructure`, and `ui` layers.
62- **New CLI commands**: `doctor` (runtime dependency checks), `about` (build info), `setup` (desktop integration), plus expanded `purge` with an interactive TUI.
63- **WebUI config improvements**: Search shortcut management (CRUD) and reset-to-defaults support.
64- **Find-in-page**: New find UI and shortcut handling.
65- Migrated GUI stack to `puregotk` + `puregotk-webkit` and disabled CGO for pure Go compilation.
66- **Omnibox rewrite**: Replaced injected Svelte/JS omnibox with a native GTK4 widget overlay.
67- Startup defers non-critical work, adds DNS prefetching and a warmed WebView pool for faster tab/pane creation.
68- SQLite WAL checkpoints happen less frequently to reduce contention.
69- Content filters skip caching invalid rules; EasyList parser prefers if-domain over unless-domain.
70- Workspace border overlays can now receive pointer input.
71- Session-based logging and session management for CLI/GUI runs.
72
73## [0.15.0] - 2025-11-29
74
75### Added
76- **Inline URL suggestions**: Fish/zsh-style ghost text completion in omnibox. As you type, shows grayed-out URL completion from history. Accept with Right Arrow (full) or Ctrl+Right (word). Ctrl+Y also accepts full suggestion. Uses trie-based prefix search with debounced queries for smooth typing.
77- **Filter list auto-update**: Async version checking using HTTP HEAD request with ETag. 2-minute startup delay, skips if checked within 24 hours. Stores version per filter list.
78- **Configurable filter lists**: New `content_filtering.filter_lists` config option. Defaults include EasyList, EasyPrivacy, and uBlock filters (annoyances, quick-fixes).
79- **Demo video**: Added feature showcase video to README (docs/media/dumber-demo.mp4).
80- **Page load progress bar**: Thin animated indicator at window bottom showing web page loading progress. Tracks WebView load events with gradient animation, auto-hides when complete.
81- **Omnibox initial history display**: Configurable behavior when opening empty omnibox via `omnibox.initial_behavior` ("recent", "most_visited", "none"). Shows initial history on open and when input is cleared. Default: recent visits.
82- **Omnibox keyboard blocking**: Prevent page scripts from stealing focus while omnibox is active.
83- **Configurable border widths**: Added `pane_mode_border_width` and `tab_mode_border_width` configuration options (default: 4px) for full border customization.
84- **Content filter caching**: Centralized content blocking service compiles filters once and caches them for instant reuse across all WebViews.
85- **CLI purge enhancements**: Separate `--cookies` and `--history` flags for granular data deletion.
86- **URL normalization**: Consistent URL storage across browser, CLI, and favicon services (strips trailing slashes, normalizes schemes).
87
88### Fixed
89- **Filter compilation race condition**: Fixed concurrent map crash when multiple filter lists compile simultaneously by using local converter instead of shared state.
90- **Omnibox search performance**: Debounce search with 2-character minimum threshold to prevent UI freeze on first keystroke. Applies to both URL/history search and find-in-page modes.
91- **Omnibox flash on load**: Load the injected GUI bundle at document-start and initialize the omnibox as soon as DOM is ready, ensuring it is ready without briefly flashing during page startup or new pane creation.
92- **Zoom toast suppression**: Suppress zoom toast notifications during browser initialization to prevent UI flash.
93- **Cosmetic filter injection**: Inject rules immediately and fix selector normalization for better ad blocking.
94
95### Changed
96- **Refactor keyboard blocking**: Move logic to main-world.ts, reduce handler.go verbosity.
97- **Border overlay architecture**: All borders (active pane, pane mode, tab mode) now use GTK overlay pattern preventing layout shifts when borders appear/disappear. Removed inactive border styling - only active panes show borders.
98- **Simplified border configuration**: Removed `inactive_border_width`, `inactive_border_color`, `show_stacked_title_border`, and `border_radius` config options. All borders are now overlay-based with no layout impact.
99- **Remove Turnstile workaround**: Removed temporary Cloudflare Turnstile CORS allowlist (no longer needed).
100
101## [0.14.1] - 2025-11-18
102
103### Added
104- **Inline tab rename**: Press `Alt+T` then `r` to rename tabs directly in the tab bar. Enter saves, Escape cancels. Tab buttons temporarily allow focus during rename, then restore original focus behavior to prevent interfering with WebView keyboard input.
105- **Cloudflare Turnstile CAPTCHA support**: Temporary CORS allowlist workaround for `challenges.cloudflare.com` to bypass WebKit's incomplete COEP credentialless implementation. Allows Turnstile-protected sites to function properly. Configurable via `enable_turnstile_workaround` (default: true).
106- **Global content filtering toggle**: New `content_filtering.enabled` config option to completely disable ad blocking when needed. Whitelist system remains available for granular control. Defaults to enabled for backward compatibility.
107
108### Fixed
109- **Search shortcut placeholders**: Support both `{query}` and `%s` placeholder formats in search shortcuts, allowing users to use either style. Also fixed domain-only URLs (e.g., "github.com") being incorrectly treated as search queries.
110- **OAuth popup handling**: Fixed OAuth popups not functioning in stacked panes and split operations by ensuring `setupPopupHandling()` is called in all pane creation code paths (finalizeStackCreation, CloseStackedPane, splitNode).
111- **WebView ID message parsing**: Fixed JSON unmarshaling errors when frontend sends numeric webviewId values instead of strings. Message handler now gracefully normalizes both string and numeric webviewId formats with fallback parsing logic.
112- **Video codec fallback**: Unblocked VP8 codec to allow fallback for ad segments, preventing playback interruptions when ads use different codecs than main content.
113- **Video buffering**: Increased buffer sizes (64 MB, 20s) to handle bursty Twitch/AV1 segments and improve streaming reliability on variable bitrate platforms.
114
115### Changed
116- **Console output cleanup**: Disabled WebKit console.log() messages to stdout to prevent page script spam. DevTools console (F12) still shows all messages.
117- **Content filtering configuration**: Refactored `content_filtering_whitelist` into structured `content_filtering` config with `enabled` boolean and `whitelist` array for better organization.
118
119## [0.14.0] - 2025-11-18
120
121### Added
122- **Zellij-style tab system**: Each tab contains an independent workspace with panes, splits, and stacks. `Ctrl+T` enters tab mode with modal keyboard control (`n`=new, `x`=close, `l/h`=navigate). `Alt+1-9/0` for direct tab switching. `Ctrl+Tab`/`Ctrl+Shift+Tab` for next/previous tab. Tab bar auto-hides with single tab. Orange border indicator (distinct from blue pane mode).
123- **International keyboard layout support**: Hardware keycode-based shortcuts for `Alt+number` keys work across all keyboard layouts (QWERTY, AZERTY, QWERTZ, etc.). Physical key position used instead of character mapping.
124- **Click-to-activate stacked panes**: Click on any collapsed title bar to instantly activate that pane. Uses GTK4 gesture clicks for native interaction feel.
125- **Title bar visual separators**: Subtle 1px borders between stacked title bars. Theme-aware colors automatically adjust for light/dark mode.
126- **UI scaling for title bars**: New `workspace.styling.ui_scale` config option (default: 1.0). Scales font size, padding, height, and favicon size. Range: 0.5 to 3.0 (e.g., 1.2 = 120% size).
127- **Favorites system**: Full favorites management with keyboard controls and persistent storage. Press `Tab` to switch between History and Favorites views. Press `Space` to add/remove items. Yellow border indicates favorited items in History view. View mode persists across sessions. Database-backed with RAM-first caching for performance.
128- **Omnibox quick navigation**: Press `Ctrl+1` through `Ctrl+9` to instantly navigate to the first 9 results, or `Ctrl+0` for the 10th. Works in both History and Favorites views. Visual number hints appear on each item. Keyboard layout independent (works on QWERTY, AZERTY, QWERTZ, etc.).
129- **Middle-click and Ctrl+click link handling**: Links can now be opened in new workspace panes using standard browser gestures (middle-click or Ctrl+left-click). New panes split in the configured direction (default: right) and respect `workspace.popups.placement` configuration. Implemented via WebKit's `decide-policy` signal to intercept navigation actions before they occur.
130- **Configurable pane border styling**: Added `workspace.styling.inactive_border_width`, `workspace.styling.inactive_border_color`, and `workspace.styling.show_stacked_title_border` config options. Active and inactive borders default to 1px to prevent layout shift, with only color changing on focus. Borders use GTK theme variables by default and support smooth CSS transitions.
131- **Configurable default search engine**: Added `default_search_engine` config option with explicit URL template format. DuckDuckGo is now the default (was Google). Users can set any search engine with `%s` placeholder (e.g., `default_search_engine = "https://duckduckgo.com/?q=%s"`).
132
133### Changed
134- **Target="_blank" and gesture link behavior**: Links with `target="_blank"`, Ctrl+click, and middle-click now open in stacked panes mode by default instead of split-right. New config option `workspace.popups.blank_target_behavior` (values: "split", "stacked", "tabbed") controls this behavior separately from JavaScript popups. Prevents browser exit when closing parent pane by marking _blank panes as popup-type.
135- **Config format**: TOML is now the default format (JSON/YAML still supported). Action bindings inverted to `action→keys` structure for maintainability with O(1) runtime lookup. Added comprehensive validation.
136- **Code cleanup**: Removed dead code files and emojis from GUI modules
137- **Bridge architecture**: Unified main-world to isolated-world bridge system with comprehensive documentation. Single dispatcher for all window function bridges (omnibox, favorites, toasts). Better separation between CustomEvents (shared between worlds) and window functions (require bridging).
138- **Omnibox spacing**: Increased vertical spacing between suggestion items from 0.65rem to 0.85rem for better readability
139- **Smart Escape key**: First press clears input text, second press closes omnibox. Empty input closes immediately.
140
141### Fixed
142- **Ctrl+Tab shortcuts**: Fixed focus cycling behavior, now properly switches between tabs
143- **Active tab visibility**: Fixed identical styling - active tab now clearly visible with distinct gray shade
144- **AZERTY keyboard support**: Alt+number shortcuts now work on all keyboard layouts using hardware keycodes
145- **Keyboard layout detection**: Fixed always detecting "en" - now correctly detects fr/de/etc layouts
146- **Zoom visual glitch**: Fixed zoom level for next page being applied before navigation completed, causing visible zoom change on current page. Zoom now applies on load-committed event instead of URI change.
147- **Toast notifications**: Fixed toast notifications not appearing for copy URL (Ctrl+Shift+C) and clipboard operations. Event name was `dumber:showToast` but ToastContainer listens for `dumber:toast`.
148- **Page reload shortcuts**: Restored `Ctrl+R`, `Ctrl+Shift+R`, `F5`, and `Ctrl+F5` shortcuts. They were registered but not actually wired to the window-level handler.
149- **Bootstrap initialization**: Fixed omnibox component not mounting due to invalid toast function check in isolated world. Toast functions now bridge correctly via CustomEvents, allowing omnibox to initialize properly.
150- **Empty state display**: History view now hides empty state when input is empty, showing it only when user has typed and no results are found. Favorites view always shows empty state with helpful hints.
151
152## [0.13.0] - 2025-10-24
153
154### Added
155- **Color scheme config**: `appearance.color_scheme` setting to force dark/light theme (`"prefer-dark"`, `"prefer-light"`, `"default"`)
156- **DNS prefetch**: Added capability to prefetch DNS for links to speed up future requests
157- **Page cache (bfcache)**: Enabled WebKit back/forward cache for instant navigation
158- **Smooth scrolling**: Enabled WebKit smooth scrolling for better UX
159- **JSON Schema**: Auto-generated config schema for IDE autocompletion and validation
160- **Parallel cache loading**: Zoom, certificate, and fuzzy caches load concurrently at startup (<100ms target)
161- **Certificate validation cache**: In-memory cache for TLS certificate decisions with graceful shutdown flushing
162
163### Changed
164- **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
165- **Zoom performance**: In-memory cache eliminates database reads during page transitions
166- **History writes**: Batched writes with background processor (flush every 5s or 50 items) to reduce I/O overhead
167- **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.
168- **Cache management**: Graceful cache flushing on shutdown prevents data loss; startup timing instrumentation with performance warnings
169
170### Fixed
171- **Graceful shutdown deadlock**: Resolved GTK main loop deadlock on Ctrl+Q by removing mutex locks and GTK calls after main loop exit
172- **CSS provider error handling**: Now properly handles errors from GTK CSS provider with logging
173- **Cache operations**: Added context timeouts to cache flush and history queue operations for graceful failure
174- Command typos now show proper error instead of opening in browser
175- History queue now uses buffered channel to prevent blocking on shutdown
176
177## [0.12.1] - 2025-10-18
178
179### Added
180- **Favicon refactoring**: WebKitGTK FaviconDatabase as single source of truth, removing fragile file-based cache and ico/bmp conversion dependencies
181  - Native favicon detection and automatic PNG export at 32x32 for CLI (dmenu)
182  - SVG favicon rasterization support
183  - Async texture loading with callbacks for non-blocking UI updates
184  - FaviconService handles favicon collection across all panes
185
186### Changed
187- Removed old favicon cache system (go-ico, go-bmp dependencies)
188- Simplified omnibox favicon handling: uses database favicon_url only
189
190### Fixed
191- Mouse button navigation: Added support for hardware mouse buttons 8/9 (back/forward)
192- Touchpad gestures: Two-finger horizontal swipe for back/forward navigation
193- Web app shortcuts: Ctrl+C, Ctrl+V, Ctrl+A now work in Gmail, VSCode web, etc.
194- Dark mode flash on startup: Set GTK dark theme preference and WebView background color before window/content creation
195- Cmd+Q and window close button now trigger graceful shutdown instead of killing the browser process
196- WebView cleanup: Properly destroy WebViews to prevent memory leaks and duplicate handler registrations when closing stacked panes
197- CLI help: Running `dumber` without arguments now shows available commands (use `--gui` or `browse` to launch GUI)
198
199## [0.12.0] - 2025-10-16
200
201### Added
202- **Native favicon support**: WebKit FaviconDatabase integration with automatic detection and caching for all panes
203- ENV=dev support to isolate test builds from production config/data in .dev/dumber/ directory
204- Content filtering whitelist config (Twitch enabled by default)
205- `dumber config` command to open config file in $VISUAL/$EDITOR or print path with `--path`
206- **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
207- **Popup behavior configuration**: Added `popup_behavior` config with four modes: `split` (default), `stacked`, `tabbed`, and `windowed` for user control over popup placement
208- **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.
209- **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
210
211### Changed
212- **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
213- **GUI bootstrap refactoring**: Extracted 400+ lines of common initialization logic into reusable bootstrap.ts module shared between injected pages and special schemes (homepage, etc.)
214- **Workspace pane mode**: Moved ~450 lines of JavaScript state machine to Go backend for more reliable keyboard handling and eliminated race conditions between webviews
215
216### Fixed
217- **TLS certificate validation restored**: Re-implemented persistent certificate error handling (broken during gotk4 migration)
218  - Interactive three-option dialog: "Go Back", "Proceed Once (Unsafe)", and "Always Accept This Site"
219  - SQLite-based hostname decision storage (hostname-only matching - GIO certificate properties are unstable)
220  - Smart expiration: "Proceed Once" temporary (not stored), "Always Accept" persists for 30 days
221  - Automatic cleanup of expired validations on application startup
222  - **Known issue**: Accepted certificates not pre-loaded into WebKit session on startup - stored decisions only apply when TLS error occurs again
223- **Content blocking restored**: Re-implemented WebKit native ad/tracker blocking (broken during gotk4 migration) using UserContentFilterStore API
224- **Script injection spam**: Fixed 100+ duplicate "Sending color palettes" messages by injecting scripts only in top frame instead of all iframes
225- **Favicon race conditions**: Eliminated duplicate downloads and file handle errors via mutex protection and proper handler registration
226- **Homepage theme switching**: Fixed color palette application for proper light/dark mode transitions
227- **Workspace pane borders**: Hide active pane border when only one pane exists to match Zellij UX
228- Enabled missing WebKitGTK6 features: WebRTC, MediaSource, LocalStorage, WebAudio, MediaStream, Clipboard
229- Cosmetic filter duplicate injection in frames
230- Config file duplicate keys (snake_case/camelCase) by using Viper's SafeWriteConfigAs
231- Config not reading newly created default config file
232- Config writing to disk on every load/reload
233- **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
234- **GTK focus event duplicates**: Added timestamp-based deduplication to prevent multiple focus enter/leave events in the same millisecond from WebKitGTK nested widgets
235- **Popup close behavior**: Fixed app exit when closing popups by excluding them from remaining pane count check
236- **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
237- **Stacked pane active border**: Fixed active border incorrectly appearing on stacked pane containers instead of individual panes
238- **Stacked pane creation**: Fixed premature Realize() call causing widget lifecycle issues during stack creation
239- **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
240- **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
241
242## [0.11.0] - 2025-10-07
243
244### Added
245- **Auto-open omnibox on blank panes**: Omnibox automatically opens when a new pane is created with about:blank, providing immediate search/navigation access
246- **Configurable default zoom**: Added `default_zoom` config (defaults to 1.2/120%). Per-domain zoom still overrides this
247- **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
248- **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
249- **Stacked pane favicons**: Title bars display site favicons with async caching. Click title bars to switch between stacked panes
250- **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
251- **Search shortcut badges**: Visual badges in omnibox input showing active shortcut prefix (e.g., "gh:", "npm:") with description labels
252- **Search shortcuts API**: Frontend bridge to fetch search shortcuts from backend `/api/config` endpoint with automatic normalization
253
254### Changed
255- **Terminal-style UI theme**: Monospace fonts (JetBrains Mono, Fira Code), sharp corners (no border-radius), dashed borders, adjusted shadows and spacing throughout omnibox components
256- **History suggestions**: Use favicon from database when available, omit automatic search shortcuts from suggestions (rely on explicit prefix commands)
257- **Search shortcuts defaults**: Updated defaults to include ddg, go, mdn, npm packages while reordering others
258- **Chrome user agent**: Updated to version 141.0.0.0 for better site compatibility
259- **CSS color system**: Removed hardcoded theme colors, now use dynamic CSS custom properties from Go-injected palette
260- **History item layout**: Removed "• domain" from titles, now highlight domain within the full URL using same color as title text
261- **Quick access logic**: Removed 20-item limit, now shows all sites with 2+ visits (pinned sites bypass visit requirement)
262- **History pagination**: Show 15 items initially (up from 10) with "Show N more" button
263- **Homepage layout**: Redesigned with improved visual hierarchy and dynamic color tokens

602  - Added Ctrl+scroll zoom in/out; refined accelerator matching so Ctrl− works across layouts.
603  - Removed layout-specific hacks; added diagnostic logs for raw minus key events.
604- Zoom persistence:
605  - Added WebView zoom-changed hook; save per-domain zoom to SQLite on every change.
606  - Log on successful save: “saved X.XX for domain.tld” and on load: “loaded X.XX for domain.tld”.
607  - Load and log initial zoom level on startup and on every navigation.
608- Build/dev ergonomics:
609  - Makefile loads `.env.local`; supports overriding `GOMODCACHE`, `GOCACHE`, `GOTMPDIR` for sandboxed builds.
610 - WebKit CGO hardening and API compatibility:
611   - Apply memory pressure settings to `WebKitNetworkSession` (correct signature) when enabled.
612   - Guarded C wrappers remove deprecation warnings across header variants; builds succeed on WebKitGTK 6.

614## [0.2.0] - 2025-09-10
615
616### Added
617- WebKitGTK 6 (GTK4) migration for the built‑in browser window:
618  - WebView constructed via `g_object_new(WEBKIT_TYPE_WEB_VIEW, …)` with a fresh `WebKitUserContentManager`.
619  - `WebKitNetworkSession` with persistent cookies (SQLite) and cache directories.
620- Native UCM messaging restored via `script-message-received::dumber` (JSCValue*), removing the JS fallback bridge.
621- Rendering mode controls:
622  - CLI flag `--rendering-mode=auto|gpu|cpu` and `DUMBER_RENDERING_MODE` env.
623  - In‑app status endpoint `dumb://homepage/api/rendering/status`.
624- Native zoom shortcuts at the WebKit layer (Ctrl/Cmd+=, +, −, 0) and GTK4 input controllers for keyboard/mouse.
625- AZERTY keyboard fix: treat underscore as minus for zoom‑out.
626- Runtime theme synchronization: watch GTK `gtk-application-prefer-dark-theme` and update page color‑scheme live.
627- Makefile target `check-webkit` to print `pkg-config` versions of GTK4/WebKitGTK 6.0/JSC 6.0.
628- Documentation updates:
629  - README now targets WebKitGTK 6 (GTK4) and lists GStreamer package requirements for Arch and Debian/Ubuntu.
630  - CLAUDE notes updated with migration status, GPU/Vulkan path, runtime theme sync, and persistence.
631
632### Changed
633- Build flags and includes now target `webkitgtk-6.0`, `gtk4`, and `javascriptcoregtk-6.0`.
634- GTK4 APIs for windowing and event handling (GtkEventController, GtkGestureClick) replace GTK3/GdkEvent paths.
635
636### Removed
637- Legacy WebKit2GTK constructors and container APIs.
638- JavaScript fallback for UCM message bridging.
639
640### Fixed
641- Header/enum compatibility for hardware acceleration policy and cookie policy across WebKit header variants.
642- Linker error for `on_theme_changed` and gpointer usage in signal connections.
643- Crashy paths mitigated by default “media safe” startup (can be disabled via `DUMBER_MEDIA_SAFE=0`).
644
645### Notes
646- GPU rendering path leverages GTK4’s renderer (Vulkan/OpenGL). Mode `auto` uses GPU when available and falls back gracefully to CPU.
647- WebKitGTK relies on GStreamer; install recommended packages for audio/video (see README).
648
649## [0.1.0] - 2025-09-09
650
651### Added
652- Initial project scaffolding, build system, and dependencies.
653- Unified CLI + GUI architecture with search shortcuts and fuzzy parsing.
654- Wails v3‑alpha browser integration (early phase).
655- Global keyboard controls with script injection (zoom/devtools, etc.).
656- Native WebKit2GTK backend migration:
657  - Custom `dumb://` scheme and `/api` endpoints: `/config`, `/history/recent`, `/history/search`, `/history/stats`.
658  - UserContentManager omnibox injection and theme initialization.
659  - Persistent WebsiteDataManager with cookies.sqlite; per‑domain zoom and title persistence.
660  - Keyboard/mouse accelerators (including mouse back/forward); debounced triggers.
661  - Homepage switched to first‑party API fetches; removed @wailsio/runtime usage.
662- Documentation and licensing: README enhancements and LICENSE added.
663
664### Changed
665- Replaced Wails runtime with native WebKit2GTK CGO bindings and homepage API.
666- Improved asset resolution and logging for the `dumb://homepage` scheme.
667
668### Fixed
669- Eliminated duplicate accelerator triggers via debouncing.
670- Corrected asset resolution and URL normalization in scheme handler.
