Release Notes

Stranger6667/jsonschema (jsonschema)

v0.34.0

Changed

• BREAKING: BasicOutput and Annotations no longer have lifetime parameters. Update type annotations from BasicOutput<'a> to BasicOutput and Annotations<'a> to Annotations.
• referencing: URI caching now avoids hash collisions and reduces lock contention.
• Update fluent-uri to 0.4.1.
• Bump MSRV to 1.83.0.
• Drop the Send + Sync bounds from Retrieve/AsyncRetrieve on wasm32.
• Use the new draftX::meta::validator() helper so meta-schema validators lazy-init on wasm32 while native targets keep borrowing the cached jsonschema::meta::MetaValidator.

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.
• Restore wasm32-unknown-unknown support. #​785

Performance

• apply now reuses cached schema locations, URI fragments, and buffers for up to ~2.5x faster validation.
• 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.

Removed

• BREAKING: Validator::config to reduce the memory footprint.
• BREAKING: Public DRAFT4_META_VALIDATOR, DRAFT6_META_VALIDATOR, DRAFT7_META_VALIDATOR, DRAFT201909_META_VALIDATOR, and DRAFT202012_META_VALIDATOR statics. Use draftX::meta::validator() helper functions instead (e.g., draft7::meta::validator()).
