8
9### Added
10- **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)
11- **Multi-pane WebView architecture**: Container-based widget management with proper reparenting, lifecycle handling, and per-pane controllers
12- **Window-level global shortcuts**: Centralized shortcut handling to prevent conflicts between multiple WebView instances
13- **Workspace configuration**: New config section with Zellij controls toggle, pane mode bindings, tab shortcuts, and popup behavior settings
14- **Configurable workspace styling**: Pane border appearance (width, color, transition duration, radius) now customizable via config with proper viewport stability
15- **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
16- **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
17- **Advanced popup deduplication system**: Intelligent duplicate popup prevention with SHA256 fingerprinting and 200ms debounce window to eliminate popup spam
18- **OAuth auto-close integration**: RFC 6749 compliant OAuth callback detection with automatic popup closure for seamless authentication flows

20- **WebView identity tracking**: Unique WebView ID system for precise popup targeting and enhanced debugging capabilities
21
22### Improved
23- WebKit integration now forces GPU compositing by default while still honoring explicit config overrides.
24- Smooth scrolling is enabled (when supported) so wheel and gesture animations feel closer to Chromium/Firefox.
25- 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.
26- Added optional DOM-level zoom (enabled by default) to avoid native viewport rescaling; falls back to WebKit zoom if the CSS path fails.
27- 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%.
28- Native accelerator bridge debounces duplicate GTK key events earlier, so Ctrl±/Ctrl+0 only fires once per physical key press.
29- Omnibox-triggered navigations now reuse the navigation controller, so saved zoom levels are applied before first paint and redundant lookups are avoided.
30- Configuration loading writes the missing `use_dom_zoom` flag into existing config files so DOM zoom defaults persist without manual edits.
31- Omnibox UI now relies on shared Tailwind theme tokens and the injected color-scheme service for light/dark parity.
32- Omnibox overlay now self-heals if hostile pages remove the injected shadow host, ensuring Ctrl/Cmd+L works everywhere.
33- Navigation shortcuts changed from Alt+Arrow to Ctrl/Cmd+Arrow for better workspace compatibility.
34- GUI components now support workspace-aware focus management with pane-specific event handling.
35- **Global zoom shortcuts**: Unified zoom handling at window level (Ctrl+/=/0/-) ensuring zoom applies to currently active pane in multi-pane workspace
36- **Workspace focus management**: Enhanced focus throttling (100ms) and active state tracking to prevent infinite loops and conflicts between panes
37- **Popup management**: Intelligent popup vs tab detection based on window features, with improved auto-close logic for OAuth and login flows
38- **Console logging**: WebView ID context injection for better debugging and log correlation across multiple panes
39
40### Changed
41- **Zoom shortcuts architecture**: Moved from per-WebView registration to centralized window-level handling for consistency with other global shortcuts

266## [0.3.0] - 2025-01-11
267
268### Added
269- WebKit memory controls (opt‑in):
270  - Env vars to tune memory/perf trade‑offs without code changes:
271    - `DUMBER_CACHE_MODEL`, `DUMBER_ENABLE_PAGE_CACHE`
272    - `DUMBER_ENABLE_MEMORY_MONITORING`, `DUMBER_MEMORY_LIMIT_MB`, `DUMBER_MEMORY_POLL_INTERVAL`

274    - `DUMBER_GC_INTERVAL`, `DUMBER_RECYCLE_THRESHOLD`
275  - Version‑guarded CGO wrappers for memory pressure and GC hooks; safe no‑ops on unsupported WebKitGTK builds.
276 - Find in page (Ctrl/Cmd+F):
277   - Omnibox refactored into a reusable component with dedicated "find" mode.
278   - Highlighting: yellow for all matches; active match in orange for clarity.

303  - Omnibox shortcut parsing now URL-encodes queries and supports `%s` placeholders.
304- Input and navigation reliability (GTK4/WebKitGTK 6):
305  - Capture-phase key controller to ensure accelerators fire consistently.
306  - Do not consume normal left/right clicks; only mouse buttons 8/9 trigger back/forward.

328  - CLI flag `--rendering-mode=auto|gpu|cpu` and `DUMBER_RENDERING_MODE` env.
329  - In‑app status endpoint `dumb://homepage/api/rendering/status`.
330- Native zoom shortcuts at the WebKit layer (Ctrl/Cmd+=, +, −, 0) and GTK4 input controllers for keyboard/mouse.
331- AZERTY keyboard fix: treat underscore as minus for zoom‑out.
332- Runtime theme synchronization: watch GTK `gtk-application-prefer-dark-theme` and update page color‑scheme live.
333- Makefile target `check-webkit` to print `pkg-config` versions of GTK4/WebKitGTK 6.0/JSC 6.0.
334- Documentation updates:

350
351### Notes
352- GPU rendering path leverages GTK4’s renderer (Vulkan/OpenGL). Mode `auto` uses GPU when available and falls back gracefully to CPU.
