+Released: 2026-04-09
+
+### Highlights
+
+- Extended `AI Playground` from a minimal prompt form into a more repeatable diagnostics workspace, and hardened `planet.sh` so AI Provider restarts can rebuild changed images and expose clearer Compose fallback behavior.
+
+### Improved
+
+- Improved [frontend/src/pages/Playground/Playground.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Playground/Playground.tsx) by adding preset scenarios, response metadata, `thinking` block visibility, raw JSON inspection, and copy actions so the page works more like a proper AI diagnostics console.
+- Improved [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by styling Playground presets, result metadata, raw response sections, and responsive action groups without breaking the single-screen workspace layout.
+- Improved [planet.sh](/home/ray/dev/linkong/planet/planet.sh) so AI Provider restarts detect code/config changes, rebuild the image when needed, and surface which Compose path is being used during image and container operations.
+
+### Fixed
+
+- Fixed the AI Provider restart path in [planet.sh](/home/ray/dev/linkong/planet/planet.sh) so code changes inside `aiprovider/` no longer stay hidden behind an old container image after `restart -a`.
+- Fixed Compose error reporting in [planet.sh](/home/ray/dev/linkong/planet/planet.sh) by making the script explicitly show `docker compose v2` first, then `docker-compose v1`, and only fail after both execution paths are exhausted.
