[Python] Release 0.60.0

Added

• Support for Python 3.15.

Changed

• Update pyo3 to 0.30.
• canonicalize and canonical.find_unsatisfiable take schema positionally only, like bundle and dereference.

Fixed

• Type stubs rejecting valid usage: dict | bool schemas, ReferencingError in except, match on error kinds.
• import jsonschema_rs.canonical.json and import jsonschema_rs.canonical.schema raising ModuleNotFoundError.
• inspect.signature of validator and Evaluation methods missing self.
• ValidationErrorKind reporting builtins as its module.
• validator_for returning instances that fail isinstance checks against Validator and draft classes.

Performance

• Validation with unfinished regex matches running each such match once instead of once per run, and comparing errors across runs in linear time instead of quadratic. #1784
• items and additionalProperties looking up a single-keyword subschema once per array or object instead of once per value.
• is_valid and validate reading fewer cache lines per subschema, by keeping error locations apart from validators.
• is_valid on recursive schemas caching only $ref results that took many steps to compute, instead of every one.
• Error evaluation paths taking memory linear in the $ref nesting depth, not quadratic. #1778
