[Python] Release 0.42.2

Fixed

• SWAR digit parser accepted bytes :–? (0x3A–0x3F) as valid digits during date, time, and date-time format validation, potentially allowing malformed values to pass.

Changed

• Custom keyword validation exceptions are now chained to the resulting ValidationError via __cause__, preserving the original exception type and message.

Performance

• Extend pattern prefix optimization to handle escaped slashes (^\/) and exact-match patterns (^\$ref$).
• Specialize enum for cases when all variants are strings.

[Rust] Release 0.42.1

Performance

• Reduce dynamic dispatch overhead for non-recursive $ref resolution.
• Cache ECMA regex transformations during format: "regex" validation.

[Ruby] Release 0.42.1

Performance

• Reduce dynamic dispatch overhead for non-recursive $ref resolution.
• Cache ECMA regex transformations during format: "regex" validation.

[Python] Release 0.42.1

Performance

• Reduce dynamic dispatch overhead for non-recursive $ref resolution.
• Cache ECMA regex transformations during format: "regex" validation.

Packaging

• Exclude rust-toolchain.toml from wheels. #1012

[Ruby] Release 0.42.0

Initial public release

[Rust] Release 0.42.0

Added

• JsonType::as_str method for zero-allocation type name access.
• ValidationErrorKind::keyword is now public.
• tls-ring feature flag to opt into using ring as the TLS crypto provider instead of the default aws-lc-rs. #997
• CLI: Support YAML (.yaml/.yml) instance files. #988

Changed

• BREAKING: Default TLS crypto provider switched back to aws-lc-rs. Users who need ring can opt in via the tls-ring feature flag. This resolves potential conflicts with other libraries using aws-lc-rs. #997

Fixed

• Panic when validating $ref targets that resolve to boolean schemas.

Performance

• Cache formatted schema locations with OnceLock to avoid repeated formatting during evaluate().

[Python] Release 0.42.0

Fixed

• Panic when validating $ref targets that resolve to boolean schemas.

Performance

• Use FFI PyList_New + PyList_SetItem for array conversion to avoid reallocations.
• Cache ValidationError, ReferencingError, and decimal.Decimal types to avoid repeated module imports.
• Cache formatted schema locations to avoid repeated formatting during evaluate().
• Use as_str instead of to_string for type names in validation errors to avoid allocations.

[Rust] Release 0.41.0

Performance

• Replace regex-based uri-template format validation with a hand-rolled RFC 6570 parser.
• Specialize items keyword for simple type schemas ({"type": "string"}, {"type": "number"}, etc.) to eliminate dynamic dispatch overhead.
• Precompute regex matches on known properties.
• Faster unevaluatedProperties validation via O(1) property lookup and short-circuit oneOf evaluation.
• Use HashMap for large set of properties.
• Lower HashMap threshold from 40 to 15 properties for faster property lookups.

[Python] Release 0.41.0

Changed

• Update pyo3 to 0.28.
• Remove unused pythonize dependency.

[Python] Release 0.40.4

Added

• Pre-built wheels for free-threaded Python (3.13t, 3.14t) on Linux, macOS, and Windows.
