+# Sentry Triage — 2026-02-19
+
+Commit: `09174fd` on `main`
+
+## Issues Triaged (5)
+
+### ACTIONABLE — Fixed in Code
+
+| ID | Title | Events | Users | Fix |
+|---|---|---|---|---|
+| WORLDMONITOR-1G | `Error: ML request unload-model timed out after 120000ms` | 30 | 27 | Wrapped `unloadModel()` in try/catch; timeout no longer leaks as unhandled rejection. Cleans up `loadedModels` set on failure. |
+| WORLDMONITOR-1F | `Error: ML request unload-model timed out after 120000ms` | 9 | 9 | Same root cause as 1G (different release build hash). |
+| WORLDMONITOR-1K | `TypeError: this.player.playVideo is not a function` | 1 | 1 | Added optional chaining (`playVideo?.()`, `pauseVideo?.()`) in `LiveNewsPanel.ts`. YT IFrame API player object may not have methods ready during initialization race. |
+
+### NOISE — Filtered
+
+| ID | Title | Events | Users | Filter |
+|---|---|---|---|---|
+| WORLDMONITOR-1J | `InternalError: too much recursion` | 1 | 1 | i18next internal `translate -> extractFromKey` cycle on Firefox 147. Added `/too much recursion/` to `ignoreErrors`. |
+| WORLDMONITOR-1H | `TypeError: Cannot read properties of null (reading 'id')` | 1 | 1 | maplibre-gl internal render crash (`_drawLayers -> renderLayers`). Extended `beforeSend` regex to suppress null `id`/`type` when stack is in map chunk. |
+
+## Files Modified
+
+| File | Change |
+|---|---|
+| `src/services/ml-worker.ts` | `unloadModel()`: try/catch around `this.request()`, clean `loadedModels` on failure |
+| `src/components/LiveNewsPanel.ts` | Optional chaining on `playVideo?.()` and `pauseVideo?.()` |
+| `src/main.ts` | Added `/too much recursion/` to `ignoreErrors`; extended maplibre `beforeSend` filter for null `id`/`type` |
+
+## Sentry Status
+
+All 5 issues marked **resolved (in next release)** via API. They will auto-reopen if errors recur after deployment.

 All notable changes to World Monitor are documented here.
 
+## [2.4.0] - 2026-02-19
+
+### Added
+
+- **Live Webcams Panel**: 2x2 grid of live YouTube webcam feeds from global hotspots with region filters (Middle East, Europe, Asia-Pacific, Americas), grid/single view toggle, idle detection, and full i18n support (#111)
+- **Linux download**: added `.AppImage` option to download banner
+
+### Changed
+
+- **Mobile detection**: use viewport width only for mobile detection; touch-capable notebooks (e.g. ROG Flow X13) now get desktop layout (#113)
+- **Webcam feeds**: curated Tel Aviv, Mecca, LA, Miami; replaced dead Tokyo feed; diverse ALL grid with Jerusalem, Tehran, Kyiv, Washington
+
+### Fixed
+
+- **Le Monde RSS**: English feed URL updated (`/en/rss/full.xml` → `/en/rss/une.xml`) to fix 404
+- **Workbox precache**: added `html` to `globPatterns` so `navigateFallback` works for offline PWA
+- **Panel ordering**: one-time migration ensures Live Webcams follows Live News for existing users
+- **Mobile popups**: improved sheet/touch/controls layout (#109)
+- **Intelligence alerts**: disabled on mobile to reduce noise (#110)
+- **RSS proxy**: added 8 missing domains to allowlist
+- **HTML tags**: repaired malformed tags in panel template literals
+- **ML worker**: wrapped `unloadModel()` in try/catch to prevent unhandled timeout rejections
+- **YouTube player**: optional chaining on `playVideo?.()` / `pauseVideo?.()` for initialization race
+- **Panel drag**: guarded `.closest()` on non-Element event targets
+- **Beta mode**: resolved race condition and timeout failures
+- **Sentry noise**: added filters for Firefox `too much recursion`, maplibre `_layers`/`id`/`type` null crashes
