@Marvin what is the oldest version of prefect that has worker infra included?

The concept of "workers" in Prefect, replacing traditional "agents" with a more flexible infrastructure approach, was introduced starting in Prefect 2.x. The workers provide enhanced control over infrastructure configurations and a more seamless infrastructure and execution environment management experience. These enhancements were documented as available features in Prefect 2.x. Here are relevant resources where you can explore further: - Prefect 3.0 documentation on upgrading from agents to workers: link. - Prefect 3.0 infrastructure concepts around workers: link. So, if you're using Prefect 2 or 3, you should have access to worker infrastructure. If you have a specific sub-version in mind within these versions, it's always a good idea to look at the release notes or version-specific documentation details. Let me know if there's anything else you'd like to explore!
