v1.1.1

🚀 Added

🌀 Execution Engine v1.8.0

Steps gated by control flow (e.g. after a ContinueIf block) can now run even when they have no data-derived lineage — meaning they don't receive batch-oriented inputs from upstream steps. Lineage and execution dimensionality are now derived from control flow predecessor steps. Existing workflows are unaffected.

• 🔀 Control flow lineage — The compiler now tracks lineage coming from control flow steps (e.g. branches after ContinueIf). When a step has no batch-oriented data inputs but is preceded by control flow steps, its execution slices and batch structure are taken from those control flow predecessors.
• 🔓 Loosened compatibility check — Previously, steps with control flow predecessors but no data-derived lineage would fail at compile time with ControlFlowDefinitionError. That check is now relaxed: lineage is derived from control flow predecessors when no input data lineage exists. The strict check still runs when the step does have data-derived lineage.
• ✨ New step patterns — Steps triggered only by control flow that don't consume batch data now compile and run correctly. For example, you can send email notifications or run other side-effect steps after a ContinueIf without wiring any data into parameters like message_parameters — the step will execute once per control flow branch.
• 🐛 Batch.remove_by_indices nested batch fix (breaking) — When removing indices via Batch.remove_by_indices, nested Batch elements are now recursively filtered by the same index set. Previously, only the top-level batch was filtered while nested batches were left unchanged, which could cause downstream blocks to silently process None values or fail outright.

Warning

One breaking change is included due to a bug fix in Batch.remove_by_indices with nested batches (see below) — impact is expected to be minimal.
