upload_file has been removed from the public methods. it's a low-level method users should not need to use. upload_file has been removed from the public methods. it's a low-level method users should not need to use.
events have changed. rather than differentiating between "event builder" and "event instance", instead there is only the instance, and you register the class.
where you had
@client.on(events.NewMessage(chats=...))
it's now
@client.on(events.NewMessage, chats=...)
this also means filters are unified, although not all have an effect on all events. from_users renamed to senders. messageread inbox is gone in favor of outgoing/incoming.
events.register, unregister, is_handler and list are gone. now you can typehint instead.
