         By enabling the queue you can control when users know their position in the queue, and set a limit on maximum number of events allowed.
         Parameters:
             status_update_rate: If "auto", Queue will send status estimations to all clients whenever a job is finished. Otherwise Queue will send status at regular intervals set by this parameter as the number of seconds.
             api_open: If True, the REST routes of the backend will be open, allowing requests made directly to those endpoints to skip the queue.
             max_size: The maximum number of events the queue will store at any given moment. If the queue is full, new events will not be added and a user will receive a message saying that the queue is full. If None, the queue size will be unlimited.
+            concurrency_count: Deprecated and has no effect. Set the concurrency_limit directly on event listeners e.g. btn.click(fn, ..., concurrency_limit=10) or gr.Interface(concurrency_limit=10). If necessary, the total number of workers can be configured via `max_threads` in launch().
         Example: (Blocks)
             with gr.Blocks() as demo:
                 button = gr.Button(label="Generate Image")
