 ### Features Added
 
-- Added new features to the EventGridClient that supports `publish_cloud_events`, `receive_cloud_events`, `acknowledge_cloud_events` , `release_cloud_events`, and `reject_cloud_events` operations. These features include a `renew_cloud_event_locks` operation, as well as a `release_with_delay` parameter on the `release_cloud_events` operation.
-- The `lock_tokens` parameter in `reject_cloud_events`, `release_cloud_events`, and `acknowledge_cloud_events` was renamed to `reject_options`, `release_options`, and `acknowledge_options`.
-- The `binary_mode` keyword argument on `publish_cloud_events` was added to allow for binary mode support when publishing single Cloud Events.
-- Added new models to support these new operations on EventGridClient.
