 ## [Unreleased]
 
+### Changed
+- **Breaking:** `get_device_warnings` is gone, and with it the `apt_proxy_url` argument.
+  The driver reports facts and the application names warnings (napalm-device-types 4.14):
+  `get_package_proxy()` says which proxy apt fetches through; pending updates were always
+  in `get_available_updates()`. Requires napalm-device-types 4.14.0; version 0.9.0.

 ### Changed
 
 - **Breaking:** `run_device_action` is gone, with `fix_snmp`, `fix_apt_proxy`,
