+- `deploy` now surfaces machine-shape parameters as flags for Agent Runtime and Cloud Run.
+- `deploy` adds a `--service-name` override.
+- `run` prints a copy-pasteable resume command in the session footer.
+- `run` no longer tears down a reused local server on a plain run.
+- `scaffold upgrade` now builds the prior-version template via `uvx`.
+- Skills setup/update no longer hangs on large `npx` output (a pipe-buffer deadlock).
+- The project-root notice now only prints when the command actually changes directory.
+- Fixed pre-existing inaccuracies in the bundled skills and generated project READMEs.
+- Source code is now published to the public GitHub repo: https://github.com/google/agents-cli
 
 ## [0.4.0] - 2026-06-10
 - Scaffolded Python templates now use **ADK 2.0 GA**. New `adk`, `adk_a2a`, and `agentic_rag` projects pin `google-adk[gcp]>=2.0.0,<3.0.0`; the `[gcp]` extra restores the OpenTelemetry GCP exporters and bundles the BigQuery client, so the separate `[bigquery-analytics]` extra is no longer needed. Cloud SQL sessions on Cloud Run and GKE keep working under 2.0. The bundled ADK coding skill and its reference docs were refreshed for 2.0.
