 # Release History
 
-## 0.1.0-preview (Unreleased)
+## 0.0.1-preview (2026-05-22)
 
-- Initial release.
+Initial preview release of the Agent Inspector extension.
+
+### Features Added
+
+- Agent Inspector extension: serves the Inspector single-page app on loopback and bridges it to a locally running agent over WebSocket JSON-RPC and HTTP/SSE proxying.
+- Added `azd ai inspector launch` to start the Inspector standalone; the `azd ai inspector` command group is kept for future subcommands.
+- Integrated with `azd ai agent run` so the Inspector is launched automatically for local agent runs (opt out with `--no-inspector`).
+
+### Other Changes
+
+- Hardened the loopback server with `Host`/`Origin` allowlisting, proxy URL constraints (http/https, loopback hosts, configured agent port), bounded WebSocket frame size, read/write deadlines, ping/pong, and Content-Security-Policy and related hardening headers on the served SPA.
+- Restricted `openUrlInBrowser` to `http`/`https` URLs.
+- Suppressed proxy body logging and stdout output when launched in silent mode from `azd ai agent run`.
+- Added panic recovery in per-message RPC goroutines and fixed a nil-map race in stream registration during session cleanup.
