chore: release by hugrbot · Pull Request #3048 · Quantinuum/hugr

hugrbot · 2026-05-05T16:05:31Z

This release includes an overhaul of the Type definition, merging it with
Terms. The hugr-model serialization now tracks granular information about
which extensions versions requirements. This improves error reporting on missing
extensions and opens the way for extension version migrations in the future.

Support for bare .json HUGR files has been removed. JSON-encoded envelopes are
still supported, but will be removed in the future.
To convert old JSON files, add the following header and footer to the file:

PREPEND = r#"HUGRiHJv?@{"modules": ["#;
APPEND = r#"],"extensions": []}"#;
