🤖 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.
