[Python] Release 0.34.0

on GitHub

Added

• Python 3.14 support.

Changed

• Update pyo3 to 0.27.

Fixed

• Hostname and IDN hostname formats now decode xn-- labels, reject leading combining marks/uppercase prefixes, and enforce the latest JSON Schema punycode context rules.

Performance

• Recursive and regular $ref compilation deduplicates validator nodes, which decreases the memory usage and improves performance.
• Validator compilation restores the regex cache for faster builds on regex-heavy schemas and precomputes absolute schema locations, trading a bit of compile time for faster apply on location-heavy workloads.
• Large schema compilation is significantly faster. #755
• unevaluatedProperties validation is 25-35% faster through optimized property marking and early-exit paths.
• unevaluatedProperties memory usage drastically reduced by eliminating redundant registry clones during compilation.
• unevaluatedItems validation is ~10% faster through early-exit optimizations and eliminating redundant validations in combinators.
