Maybe id and latest_version could be underscored as well?

There was a problem hiding this comment.
Made them hidden, and added an id(self) getter. The latest version can be accessed via .latest.version

🤖 I have created a release *beep* *boop* --- ## [0.16.0](hugr-py-v0.15.4...hugr-py-v0.16.0) (2026-04-01) This release changes the default text serialization format from JSON to `MODEL_WITH_EXTS` (the JSON format is now deprecated). It also adds the ability to link packages and modules from Python, renders operation type arguments in HUGR visualizations, introduces a new `debug_info` module for attaching source-level debug metadata to nodes, and introduces multi-version support in `ExtensionRegistry`, allowing different versions of the same extension to coexist in the same registry. ### ⚠ BREAKING CHANGES * `ExtensionRegistry` may now contain multiple versions of the same extension. `.extensions` is now an iterator of the latest versions instead of a dictionary. `.register_updated` and `.add_extension` have been replaced with a singular `.register`. * Default `EnvelopeConfig` changed from `EnvelopeFormat.JSON` to `EnvelopeFormat.MODEL_WITH_EXTS`. * Substituted `hugr-py/src/hugr/tys.py::_type_str` with `hugr-py/src/hugr/utils.py::name_w_args`. ### Features * Add debug info metadata specification in `hugr-py` ([#2971](#2971)) ([a4da8ef](a4da8ef)) * Allow multiple versions of an extension in an ExtensionRegistry ([#3005](#3005)) ([ee90cd1](ee90cd1)) * Deprecate JSON serialization format ([#2991](#2991)) ([0f7a880](0f7a880)) * Operation parameter rendering in HUGR visualizations ([#2995](#2995)) ([d619148](d619148)) * Allow linking packages and modules from Python ([#2947](#2947)) ([329c243](329c243)) * Make `_composable_pass` and `_scope` public modules ([#2962](#2962)) ([1d6af9a](1d6af9a)), closes [#2961](#2961) * Allow missing ext versions ExtensionDesc metadata ([#2979](#2979)) ([bc1c445](bc1c445)) * Allow dfg conversion in to TrackedDfg ([#2993](#2993)) ([3bd7a88](3bd7a88)) ### Bug Fixes * Allow both _composable_pass and composable_pass imports ([#2965](#2965)) ([0a5664d](0a5664d)) * Allow both _scope and scope imports ([#3003](#3003)) ([de0458c](de0458c)) * Always do extension resolution when loading packages and hugrs ([#2953](#2953)) ([0086d2a](0086d2a)) * Correct pyo3 module definitions and add missing exception class export ([#2964](#2964)) ([3df73f4](3df73f4)) * Include extensions during link serialization ([#2992](#2992)) ([9236e89](9236e89)) * Prefix names with underscores during serialization ([#2989](#2989)) ([8aab636](8aab636)) * Use valid identifiers when constructing AST model ([#2973](#2973)) ([8750a6b](8750a6b)) --- This PR was generated with [Release Please](https://github.com/googleapis/release-please).

Breaking part of #3000 for the python interface:
Allows
ExtensionRegistryes to contain multiple versions of the same registry.Since the
extensionsattribute was public changing this was a breaking change.This PR replaces it with a
versioned_extensions: dict[ExtensionId, ExtensionVersions], whereExtensionVersionscontains multiple versions of the same extension.It also modifies a couple methods to expose the new behaviour.
We are not actually exploiting the multi-version capability yet. That will be done in a PR actually addressing #3000.
BREAKING CHANGE:
ExtensionRegistrymay now contain multiple versions of the same extension..extensionsis now an iterator of the latest versions instead of a dictionary..register_updatedand.add_extensionhave been replaced with a singular.register.
