 New in Seafile Pro 7.1.16 and Pro 8.0.3: You can set the maximum number of files contained in a library that can be synced by the Seafile client. The default is 100000. When you download a repo, Seafile client will request fs id list, and you can control the timeout period of this request through `fs_id_list_request_timeout` configuration, which defaults to 5 minutes. These two options are added to prevent long fs-id-list requests from overloading the server.
 
+Since Pro 8.0.4 version, you can set both options to -1, to allow unlimited size and timeout.
