History

3.1.0 (2019-03-22)

• Agents now run in a single event loop managed by the container.

• Behaviors can be waited for using the “join” method.

• To check if a behaviours is done you can now use the “is_done” method.

• The “setup” method is now a coroutine.

• New “quit_spade” helper to stop the whole process.

• The “start” and “stop” methods change depending on the context, since it is the container who will properly start or stop the agent. They return a coroutine or a future depending on whether they are called from a coroutine or a synchronous method.
