🤖 I have created a release *beep* *boop* --- ## [0.13.0rc1](hugr-py-v0.12.2...hugr-py-v0.13.0rc1) (2025-07-24) ### ⚠ BREAKING CHANGES * Lowering functions in extension operations are now encoded as binary envelopes. Older hugr versions will error out when trying to load them. * **py:** `EnvelopeConfig::BINARY` now uses the model binary encoding. `EnvelopeFormat.MODULE` is now `EnvelopeFormat.MODEL`. `EnvelopeFormat.MODULE_WITH_EXTS` is now `EnvelopeFormat.MODEL_WITH_EXTS` * hugr-model: Symbol has an extra field * Renamed the `Any` type bound to `Linear` * The model CFG signature types were changed. * Added `TypeParam`s and `TypeArg`s corresponding to floats and bytes. * `TypeArg::Sequence` needs to be replaced with `TypeArg::List` or `TypeArg::Tuple` * FuncDefns must be moved to beneath Module. `Container::define_function` is gone, use `HugrBuilder::module_root_builder`; similarly in hugr-py `DefinitionBuilder` (`define_function` -> `module_root_builder().define_function`). In hugr-llvm, some uses of ### Features * Add `BorrowArray` extension ([#2395](#2395)) ([782687e](782687e)) * Add `MakeError` op ([#2377](#2377)) ([909a794](909a794)), closes [#1863](#1863) * add toposort to HUGR-py ([#2367](#2367)) ([34eed34](34eed34)) * Add Visibility to FuncDefn/FuncDecl.

The python lib had a
_serialization.ops.TupleValuestruct for special cases of single-variant sums, that got encoded with an special tag.The rust does not have the specialized varinat, and simply loads it as
SumValue.This PR removes the unnecessary special case from the python side, to simplify the serialization logic and help with the roundtrip checks.
The json schemas have been updated, but the change is non-breaking.
