+## Zend/ProgressBar
+
+The old bundled version of Zend/ProgressBar was replaced by a current version of laminas-progressbar.
+
+Due to laminas-zendframework-bridge this update is a drop-in replacement.
+Existing code should continue to work as-is.

+It is recommended to cleanly migrate to laminas-progressbar to allow for a future removal of the bridge.
+Updating the `use` imports should be sufficient to switch to the laminas-progressbar.
