limit is not used in get_range_request of 0.12.0

[fly-studio]

I want to read the last revision of a key with prefix

response = etcd.get_prefix_response(settings.CONF_PREFIX, sort_order='descend', sort_target='mod', limit=1)
print(response.header.revision)

but report grpc body is greater then 4M when key/value is big in etcd

Received_message larger than max(4194304)  

This problem occurs because limit is not used in the body of _build_get_range_request,
but fix in the master branch, When will the next stable release be?

I'm facing this issue too.

I have solved this issue by setting grpc options.
etcd3.client(host=host, port=port, grpc_options={'grpc.max_receive_message_length': -1, 'grpc.max_send_message_length': -1})

I have solved as following setting.
etcd3.client(host=host, port=port, grpc_options=[('grpc.max_receive_message_length', -1), ('grpc.max_send_message_length', -1)])

grpc_options is parsed as a list of the key-value tuples.
