+# Release Notes — Unreleased (since v0.4.1)
+
+**Date:** Pending
+**Status:** Unreleased
+
+## Summary
+
+Two changes have landed on `main` since the v0.4.1 release:
+
+1. **Golden-path CLI integration tests** — New mocked HTTP test coverage for lens management, custom bangs, redirects, and saved-assistant selection commands.
+2. **CI concurrency groups** — All four CI workflows now use `concurrency` groups to cancel redundant in-flight runs when a new push arrives on the same branch.
+
+## Changes
+
+### Testing
+
+- Added golden-path integration tests for CLI commands with mocked HTTP responses, covering lens, bangs, redirects, and saved-assistant flows. (faa7346)
+
+### CI/CD
+
+- Added concurrency groups to all four GitHub Actions workflows, reducing wasted CI minutes by auto-cancelling superseded runs. (c03d6ea)
