-Uses are now able to pass any option to `collection.watch()` and if it is invalid in the `$changeStream` stage of the pipeline the server will error. This is to allow users to provide newly added options quickly that are not in our public types.
+Users can now pass any option to `collection.watch()`. If an option is invalid for the `$changeStream` stage of the pipeline, the server will return an error. This change makes it possible to use newly introduced server options without waiting for them to become available in our public type definitions and eliminates the risk of valid but unrecognized options being silently ignored.
