This release brings the fixes for Home Assistant allowing a WebSocket connection before all integrations are fully loaded.
All event node statuses now use the ring shape and a new status of running was added to show when HA is in the running state. Event nodes will not start receiving events until HA is in the running state. This should be the same functionality as HA pre v0.111.0. The call-service, fire event, and API nodes can be used at any point after the connection is made and don't need to wait until the running state.
If you're using the Node-RED component those nodes will become functional when the component is loaded in HA, which could be before HA enters the running state.
