60  - **High bitrate streaming support**: Enables premium quality streaming (650+ Mbps) with proper buffer management
61  - Fixes previous limitation where forcing AV1 would cap YouTube playback at 1080p maximum

174
175## [0.3.0] - 2025-01-11
176
177### Added
178- WebKit memory controls (opt‑in):
179  - Env vars to tune memory/perf trade‑offs without code changes:
180    - `DUMBER_CACHE_MODEL`, `DUMBER_ENABLE_PAGE_CACHE`
181    - `DUMBER_ENABLE_MEMORY_MONITORING`, `DUMBER_MEMORY_LIMIT_MB`, `DUMBER_MEMORY_POLL_INTERVAL`
182    - `DUMBER_MEMORY_CONSERVATIVE`, `DUMBER_MEMORY_STRICT`, `DUMBER_MEMORY_KILL`
183    - `DUMBER_GC_INTERVAL`, `DUMBER_RECYCLE_THRESHOLD`
184  - Version‑guarded CGO wrappers for memory pressure and GC hooks; safe no‑ops on unsupported WebKitGTK builds.
185 - Find in page (Ctrl/Cmd+F):
186   - Omnibox refactored into a reusable component with dedicated "find" mode.
187   - Highlighting: yellow for all matches; active match in orange for clarity.
188   - Match list with context (right side stops at nearest punctuation: . , ; : -).
189   - Navigation UX:
190     - ArrowUp/Down move selection and scroll the overlay list (page scroll disabled while open).
191     - Enter centers on the active match and closes; Shift+Enter goes to previous; Alt+Enter centers without closing.
192     - Hover focuses input and selects list items; click outside closes the overlay.
193     - Faded overlay with subtle blur when reviewing matches; opacity restores on input focus/typing.
194   - Programmatic API: `OpenFind(initial)`, `FindQuery(q)`, `CloseFind()` on `WebView`.
195
196### Changed
197- Performance‑first defaults retained:
198  - Cache model set to “WebBrowser”, page cache enabled, DevTools available.
199  - No implicit memory pressure or GC enabled by default; all memory tuning is opt‑in.
200
201### Removed
202- Deprecated offline app‑cache calls eliminated (no‑ops) to avoid warnings and brittle builds.
203
204### Fixed
205- Homepage Recent History layout:
206  - Show single-line entries as “{Title} – {Domain} – {URL}”.
207  - Truncate long URLs with a gradient fade; prevent horizontal overflow.
208  - Adjusted styling so URL is darker for readability.
209- Search shortcuts and config interop:
210  - Backend SearchShortcut now serializes `url`/`description` with JSON tags.
211  - Frontend normalizes field casing and extracts base URLs, handling `%s` and `{query}` templates.
212  - Omnibox shortcut parsing now URL-encodes queries and supports `%s` placeholders.
213- Input and navigation reliability (GTK4/WebKitGTK 6):
214  - Capture-phase key controller to ensure accelerators fire consistently.
215  - Do not consume normal left/right clicks; only mouse buttons 8/9 trigger back/forward.
216  - Added Alt+ArrowLeft/Right navigation and enabled two-finger swipe back/forward when supported.
217  - Added Ctrl+scroll zoom in/out; refined accelerator matching so Ctrl− works across layouts.
218  - Removed layout-specific hacks; added diagnostic logs for raw minus key events.
219- Zoom persistence:
220  - Added WebView zoom-changed hook; save per-domain zoom to SQLite on every change.
221  - Log on successful save: “saved X.XX for domain.tld” and on load: “loaded X.XX for domain.tld”.
222  - Load and log initial zoom level on startup and on every navigation.
223- Build/dev ergonomics:
224  - Makefile loads `.env.local`; supports overriding `GOMODCACHE`, `GOCACHE`, `GOTMPDIR` for sandboxed builds.
225 - WebKit CGO hardening and API compatibility:
226   - Apply memory pressure settings to `WebKitNetworkSession` (correct signature) when enabled.
227   - Guarded C wrappers remove deprecation warnings across header variants; builds succeed on WebKitGTK 6.
228
229## [0.2.0] - 2025-09-10
230
231### Added
232- WebKitGTK 6 (GTK4) migration for the built‑in browser window:
233  - WebView constructed via `g_object_new(WEBKIT_TYPE_WEB_VIEW, …)` with a fresh `WebKitUserContentManager`.
234  - `WebKitNetworkSession` with persistent cookies (SQLite) and cache directories.
235- Native UCM messaging restored via `script-message-received::dumber` (JSCValue*), removing the JS fallback bridge.
236- Rendering mode controls:
237  - CLI flag `--rendering-mode=auto|gpu|cpu` and `DUMBER_RENDERING_MODE` env.
238  - In‑app status endpoint `dumb://homepage/api/rendering/status`.
239- Native zoom shortcuts at the WebKit layer (Ctrl/Cmd+=, +, −, 0) and GTK4 input controllers for keyboard/mouse.
240- AZERTY keyboard fix: treat underscore as minus for zoom‑out.
241- Runtime theme synchronization: watch GTK `gtk-application-prefer-dark-theme` and update page color‑scheme live.
242- Makefile target `check-webkit` to print `pkg-config` versions of GTK4/WebKitGTK 6.0/JSC 6.0.
243- Documentation updates:
244  - README now targets WebKitGTK 6 (GTK4) and lists GStreamer package requirements for Arch and Debian/Ubuntu.
245  - CLAUDE notes updated with migration status, GPU/Vulkan path, runtime theme sync, and persistence.
246
247### Changed
248- Build flags and includes now target `webkitgtk-6.0`, `gtk4`, and `javascriptcoregtk-6.0`.
249- GTK4 APIs for windowing and event handling (GtkEventController, GtkGestureClick) replace GTK3/GdkEvent paths.
250
251### Removed
252- Legacy WebKit2GTK constructors and container APIs.
253- JavaScript fallback for UCM message bridging.
254
255### Fixed
256- Header/enum compatibility for hardware acceleration policy and cookie policy across WebKit header variants.
257- Linker error for `on_theme_changed` and gpointer usage in signal connections.
258- Crashy paths mitigated by default “media safe” startup (can be disabled via `DUMBER_MEDIA_SAFE=0`).
259
260### Notes
261- GPU rendering path leverages GTK4’s renderer (Vulkan/OpenGL). Mode `auto` uses GPU when available and falls back gracefully to CPU.
262- WebKitGTK relies on GStreamer; install recommended packages for audio/video (see README).
263

273  - UserContentManager omnibox injection and theme initialization.
274  - Persistent WebsiteDataManager with cookies.sqlite; per‑domain zoom and title persistence.
275  - Keyboard/mouse accelerators (including mouse back/forward); debounced triggers.
