3.0.1: The Director's Cut

3.0.1

This release contains a large collection of relatively small improvements and bug fixes on the back of our major 3.0.0 release. One particular set of improvements that I'd like to focus on are enhancements to server side logging and event handling. We received a few reports of task run states not showing up in the UI/API. It's important to note that events - and now task run states! - require a websocket connection to the API (the good news is that this will not disrupt workflow execution). Websockets are sometimes blocked by default in firewalls and network configuration, so we are working to raise failures to establish such a connection more prominently and potentially allow for alternative configurations. If you notice any issues with this, please let us know!
