Release 2.16.4
Flow Run Graph updates
The Flow Run Graph has been updated to display additional layers of information! Interactive and real-time state changes and artifacts are now visible in context on the graph.
These new layers are available for opt-in usage via the PREFECT_EXPERIMENTAL_ENABLE_ARTIFACTS_ON_FLOW_RUN_GRAPH
and PREFECT_EXPERIMENTAL_ENABLE_STATES_ON_FLOW_RUN_GRAPH
settings.
Agents
A year ago, we released workers as a replacement for agents. Workers significantly enhance the experience of deploying flows and simplify the specification of each flow's infrastructure and runtime environment.
With this release we are adding a six month (September 14) deprecation warning to agents and related concepts. Please note that:
- Deprecation will not impact or break any work running with agents and agent-related concepts - although we encourage users to upgrade to workers because they provide a better deployment experience, you can continue to use existing agents and related concepts after deprecation
- After September 14, Prefect Cloud users will not be able to create new agent work pools or infrastructure blocks
- After September 14, new minor versions of the Prefect Python package will not include agents
Like agents, workers support creating deployments through the Prefect CLI and through Python, but require different syntax. For more information, please refer to the Upgrade from Agents to Workers guide.
