 - Fixed [frontend/public/earth/css/info-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/info-panel.css) so the Earth brand area now uses consistent `earth-brand` component selectors and English-specific typography hooks, avoiding the earlier one-off `brand-banner` naming drift and duplicated title styles.

+Released: 2026-04-12
+
+### Highlights
+
+- Added an operator-facing TV live module to Earth, including backend-configurable live sources, a draggable/resizable live-news HUD window, default global news channels, and a dedicated settings workflow so the Earth page can open real news playback instead of only static telemetry.
+
+### Added
+
+- Added [backend/app/api/v1/tv.py](/home/ray/dev/linkong/planet/backend/app/api/v1/tv.py), [backend/app/services/tv_streams.py](/home/ray/dev/linkong/planet/backend/app/services/tv_streams.py), and [backend/app/services/collectors/news_live_streams.py](/home/ray/dev/linkong/planet/backend/app/services/collectors/news_live_streams.py) to provide TV source configuration, public stream payloads, a guarded HLS proxy path, and a collector entry point for future world-news live-source ingestion.
+- Added the Earth TV HUD workspace through [frontend/public/earth/index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html), [frontend/public/earth/js/tv.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/tv.js), and [frontend/public/earth/css/tv-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/tv-panel.css), including toolbar access, draggable/closable behavior, resize support, direct video/HLS playback, iframe fallback, and per-channel external-open handling.
+- Added [docs/earth-tv-live-module-plan.md](/home/ray/dev/linkong/planet/docs/earth-tv-live-module-plan.md) and [docs/news-live-streams-collector-format.md](/home/ray/dev/linkong/planet/docs/news-live-streams-collector-format.md) to document the TV module rollout plan and the expected collector payload format for future curated live-channel ingestion.
+
+### Improved
+
+- Improved [frontend/src/pages/Settings/Settings.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Settings/Settings.tsx), [backend/app/api/v1/settings.py](/home/ray/dev/linkong/planet/backend/app/api/v1/settings.py), and [backend/app/core/datasource_defaults.py](/home/ray/dev/linkong/planet/backend/app/core/datasource_defaults.py) by adding TV source administration to system settings and registering the `news_live_streams` datasource as a first-class configurable collector.
+- Improved [backend/app/services/tv_streams.py](/home/ray/dev/linkong/planet/backend/app/services/tv_streams.py) by seeding a curated first-pass news channel catalog that now defaults to `CGTN English` YouTube playback while keeping `CCTV-4` as a built-in fallback and exposing additional Reuters, CGTN, DW, Al Jazeera, Arirang, ABP, and SABC entries for operator testing.
+
+### Fixed
+
+- Fixed [frontend/public/earth/js/tv.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/tv.js) and [frontend/public/earth/index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html) so HLS/video playback now actively attempts autoplay in the TV panel instead of only loading metadata and leaving the player visually idle.
+- Fixed [frontend/public/earth/css/tv-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/tv-panel.css) so the TV source selector and action controls better match the Earth HUD dark theme instead of falling back to a bright native dropdown presentation.
