--- failure enum_struct_variant_field_added: pub enum struct variant field added ---

Description:
An enum's exhaustive struct variant has a new field, which has to be included when constructing or matching on this variant.
        ref: https://doc.rust-lang.org/reference/attributes/type_system.html#the-non_exhaustive-attribute

hugr/CHANGELOG.md

+This release includes a restructuration of the optimisation pass API, a major
+upgrade to LLVM 21, and bumps the MSRV to Rust 1.91.
+
+Composable passes can now be configured with a scope to indicate which parts of the
+Hugr they should be applied to, and which parts they are allowed to modify.
+Implementations of the trait should adhere to this configuration.
+
+The `hugr-passes` crate is no longer reexported from `hugr::algorithms`. It will
+be integrated into `tket` in the future, but it should be used directly
+as `hugr_passes` for now.
+
+Building the crate with the `llvm` feature will now require LLVM 21.1 to be installed.
+See the [DEVELOPMENT.md](https://github.com/Quantinuum/hugr/blob/main/DEVELOPMENT.md) file for updated instructions on setting up the development environment.
