The Prefect webhook feature was mentioned in release notes for version 2.0a4. However, the specific release date is not provided in the excerpt. For more detailed information, including the exact release date, you can refer to the
Prefect Release Notes on GitHub.
As for the Prefect automations release, the provided excerpt does not specify an exact release date either. It simply explains that automations in Prefect Cloud can be configured to execute actions based on trigger conditions related to flows and work pools. The information about automations is from a page in the Prefect documentation which you can find
here.
If you need the exact release dates, I can attempt to find more detailed information by looking through the release notes or announcements. Would you like me to do that?
