Publish and versions
Most builders need this page after Playground looks right. Operators do not install AI Flow from here — Studio already hosts it.
Save draft vs Publish
On Graph, Save draft stores the working copy. Publish opens Publish flow.

The dialog says: snapshot the current graph as a new immutable version. Published versions can be rolled back. Optional Release note describes what changed.
Draft save does not appear on the Versions tab.
Versions tab

If you have never published, you will see No published versions yet. Use Publish on the Graph tab first.
Row actions on the flow list
From the … menu on a flow:

- Open — editor
- Playground — jump straight to chat test
- View traces — observability
- Versions — published snapshots
- Delete — remove the flow (confirm first)
