Unclear It is not clear what this changes in how workflows behave.
What
The parallel() and pipeline() helpers in workflows now run each item in its own slot. A slot is a separate space that keeps that item's state apart from the others. When the items finish, their state is merged back together. Before, items ran directly with no per-item state.
Why
This may affect the order in which workflow agents run or how their results are traced back to them.
