+generated for you and placed next to your JSON config.
 - **The `act.py` binary; instead, invoke tests directly.** Upon running
 `act.py`, a deprecation warning will provide instructions for how to invoke
 antlion tests without act.py and with the newly generated YAML config.
 
 ### Added
 
-- Mobly support. All tests have been refactored to allow direct running with the
-Mobly test runner. If using act.py, ACTS JSON config will be converted to
-compatible Mobly YAML config then passed directly to Mobly's config parser. See
-notes for this release's deprecations above.
+- Presubmit testing in [CV][CV] (aka CQ). All tests specified with the
+`qemu_env` environment will run before every antlion CL is submitted.
+- Postsubmit testing in [CI][CI]. See [Milo][builders] for an exhaustive list of
+builders.
 - [EditorConfig](https://editorconfig.org) file for consistent coding styles.
 Installing an EditorConfig plugin for your editor is highly recommended.
