 ## [Unreleased]
+
 ### Changed
 - Updated all uses of `actions/checkout` from `v3` (using node 16) to `v4` (using node 20), because [actions using node 16 are deprecated](https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/) and will stop working in the future.
 * ACTION SUGGESTED: In order to avoid the node 16 deprecation warnings, update your workflows to use `actions/checkout@v4`.
 
+### Deprecated
+- The `phpcpd` command (that uses the [PHP Copy/Paste Detector](https://github.com/sebastianbergmann/phpcpd), now abandoned) has been deprecated in this `moodle-plugin-ci` release (4.4.0) and will be removed in 5.0.0. No replacement is planned.
+- ACTION SUGGESTED: In order to avoid deprecation warnings or annotations, proceed to remove this command from your workflows. Note that any use will throw an error in the next major release (5.0.0).
+
 ## [4.3.2] - 2024-01-26
 ### Changed
 - Modified internal CI scripts towards better Codecov future support.
