0.17.0 (2026-05-29)

⚠ BREAKING CHANGES

• hugr-llvm: hugr-llvm::emit::EmitHugr::emit_hugr::emit_module takes two new args: emit_debug: bool and ptr_size: u32. In addition, hugr_core::views::render::NodeLabel has a new variant MetadataValues which combines a numeric label and JSON metadata values.
• Hugrs are no longer guaranteed to have an Order edge representing the ordering constraint from each nonlocal Ext edge; require HugrView impls to provide scheduling_graph; remove deprecated region_portgraph(), as_petgraph(), into_region_portgraph(),
