 All notable user-visible changes to `pyro-mcp` are documented here.
 
+## 3.0.0
+
+- Promoted the workspace-first product surface to stable across the CLI, Python SDK, and MCP
+  server, with `pyro run` retained as the stable one-shot entrypoint.
+- Repositioned the main docs, help text, examples, and walkthrough assets around the stable
+  workspace path: create, sync, exec or shell, services, snapshots/reset, diff/export, and
+  delete.
+- Froze the `3.x` public contract around the current workspace surface without introducing new
+  runtime capability in this release.
+
 ## 2.10.0
 
 - Replaced the workspace-level boolean network toggle with explicit workspace network policies:

+## Stable Workspace Path
+
+`pyro run` is the stable one-shot entrypoint. `pyro workspace ...` is the stable path when an
+agent needs one sandbox to stay alive across repeated commands, shells, services, checkpoints,
+diffs, exports, and reset.
+
+The commands below use plain `pyro ...`. Run the same flow with `uvx --from pyro-mcp pyro ...`
+for the published package, or `uv run pyro ...` from a source checkout.
+
+```bash
+uv tool install pyro-mcp
+WORKSPACE_ID="$(pyro workspace create debian:12 --seed-path ./repo --json | python -c 'import json,sys; print(json.load(sys.stdin)["workspace_id"])')"
+pyro workspace sync push "$WORKSPACE_ID" ./changes

+pyro workspace reset "$WORKSPACE_ID" --snapshot checkpoint

+pyro workspace delete "$WORKSPACE_ID"
