 ## Upgrading
 
-- `FileWatcher`: The file polling mechanism is now enabled by default. This provides reliable and consistent file monitoring on network file systems (e.g., CIFS). However, it may have a performance impact on local file systems or when monitoring a large number of files.
+- `FileWatcher`: The file polling mechanism is now forced by default. This provides reliable and consistent file monitoring on network file systems (e.g., CIFS). However, it may have a performance impact on local file systems or when monitoring a large number of files.
   - To disable file polling, set the `force_polling` parameter to `False`.
   - The `polling_interval` parameter defines the interval for polling changes. This is relevant only when polling is enabled and defaults to 1 second.
