Changelog

Unreleased

0.45.1 - 2026-04-06

Fixed

  • Incorrect handling of multipleOf validation for negative numeric instances.
  • Incorrect handling of duration format when hours and seconds appear without minutes, or years and days without months.

0.45.0 - 2026-03-08

Added

  • bundle(schema) / async_bundle(schema) / ValidationOptions::bundle: produce a Compound Schema Document with external $ref targets embedded in a draft-appropriate container (definitions for Draft 4/6/7, $defs for Draft 2019-09/2020-12) while preserving $ref values. #791.
  • CLI: jsonschema validate and jsonschema bundle subcommands. Flat invocation (jsonschema schema.json -i …) is deprecated — use jsonschema validate instead. #791.
  • ValidationError::absolute_keyword_location() to get the absolute keyword location URI of the schema node that produced the error. #737.

Changed

  • ValidationError::into_parts() now returns ValidationErrorParts instead of a tuple.

0.44.1 - 2026-03-03

Fixed

  • hostname format now applies legacy RFC 1034 semantics in Draft 4/6 and keeps IDNA A-label validation in Draft 7+.

0.44.0 - 2026-03-02

Added

  • canonical::json::to_string(value) for canonical JSON serialization (stable key ordering and numeric normalization), useful for deduplicating equivalent JSON Schemas.

Fixed

  • Do not produce annotations for non-string instances from contentMediaType, contentEncoding, and contentSchema keywords.

0.43.0 - 2026-02-28

Performance

  • Optimize pattern and patternProperties for ^(a|b|c)$ alternations via linear array scan.
  • Optimize ^\S*$ patterns by replacing regex with a direct ECMA-262 whitespace check.

Fixed

  • anyOf, format, unevaluatedProperties, and unevaluatedItems now correctly collect annotations per spec.

0.42.2 - 2026-02-26

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.

Performance

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

0.42.1 - 2026-02-17

Performance

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

0.42.0 - 2026-02-14

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 in text output mode. #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().

0.41.0 - 2026-02-04

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.

0.40.2 - 2026-01-30

Changed

  • Exclude internal tracker field from ValidationError Debug output.
  • Switch HTTP client TLS crypto backend from aws-lc-rs to ring to simplify building from source on some Linux distributions. #957

Fixed

  • type: integer validation in Draft 4 now correctly accepts large integers outside the i64/u64 range when arbitrary-precision feature is enabled.

0.40.1 - 2026-01-30

Changed

  • ValidationErrorKind::Custom now includes a keyword field containing the custom keyword name.

Performance

  • Faster validation via cost-based keyword ordering.
  • Faster patternProperties for simple prefix patterns (e.g., ^x-).

0.40.0 - 2026-01-18

Added

  • HttpOptions and ValidationOptions::with_http_options() for configuring HTTP client behavior (timeouts, TLS verification, custom CA certificates) when fetching external schemas.
  • CLI: --timeout, --connect-timeout, --insecure, and --cacert flags for HTTP configuration.

0.39.0 - 2026-01-16

Added

  • ValidationError::evaluation_path() for the dynamic path including $ref traversals.

Changed

  • BREAKING: Simplified custom keyword API - Keyword::validate no longer receives path parameters, and ValidationError::custom only takes a message.

Fixed

  • schemaLocation in evaluation output now excludes $ref/$dynamicRef/$recursiveRef per JSON Schema spec.

Performance

  • evaluate(): 4.5-30x faster on complex schemas, 12-89% faster overall.
  • Recursive schemas with oneOf/anyOf: ~4000x faster via memoization. #930

0.38.1 - 2025-12-25

Fixed

  • multipleOf validation for large u64 values beyond i64::MAX with arbitrary-precision feature.
  • Validator not being Send + Sync on WASM targets. #915

0.37.4 - 2025-11-30

Fixed

  • Local $ref resolution within fragment-extracted external resources. #892

Removed

  • Deprecated PrimitiveType & PrimitiveTypesBitMap.

0.37.3 - 2025-11-28

Fixed

  • External resources not discovered within subresources of local $ref targets. #892

0.37.2 - 2025-11-27

Fixed

  • External resources not discovered through chained local $ref references. #892

0.37.1 - 2025-11-19

Fixed

  • Stack overflow on empty $ref value. #886

0.37.0 - 2025-11-19

Added

  • evaluate() top-level function for convenient access to structured validation output.
  • CLI: Schema-only validation now also validates all referenced schemas. #804
  • Support for additional contentEncoding values per RFC 4648: base64url, base32, base32hex, and base16. These encodings are now validated alongside the existing base64 support in Draft 6 and 7. #26
  • validator.iter_errors(instance).into_errors(). It returns a ValidationErrors type that collects validation errors and implements std::error::Error. #451

Changed

  • BREAKING: ValidationError fields are private; use instance(), kind(), instance_path(), and schema_path() instead of accessing struct fields directly.
  • BREAKING: ErrorIterator is now a newtype wrapper instead of Box<dyn ValidationErrorIterator>.

Performance

  • validate and other APIs returning Result<_, ValidationError> are 5–10% faster in some workloads due to the smaller error handle.
  • evaluate: Avoiding deep clones of unmatched keyword values (e.g., title, description, examples) on every schema node evaluation by using Arc internally. Can be multiple times faster for schemas with large annotations.

0.36.0 - 2025-11-18

Added

  • CLI: Structured --output flag|list|hierarchical modes now stream newline-delimited JSON records with schema/instance metadata plus JSON Schema Output v1 payloads (default text output remains human-readable).
  • CLI: --errors-only flag to suppress successful validation output and only show failures.
  • CLI: When invoked with only a schema file (no instances), validates the schema against its meta-schema. #804
  • New Validator::evaluate() API exposes JSON Schema Output v1 (flag/list/hierarchical) reports along with iterator helpers for annotations and errors.
  • meta::validator_for() function to build validators for meta-schema validation with full Validator API access.
  • Validator now implements Clone. #809

Removed

  • Validator::apply(), Output, and BasicOutput types have been removed in favor of the richer evaluate() API.

0.35.0 - 2025-11-16

Added

  • Support for custom meta-schemas. Schemas with custom $schema URIs can now be used by registering their meta-schemas in the Registry via jsonschema::options().with_registry(). #664
  • arbitrary-precision feature for exact numeric validation of large integers and decimals beyond standard floating-point limits. #103
  • Support for HTTPS $schema URIs for drafts 04, 06, and 07 (e.g., https://json-schema.org/draft-07/schema). #802

Changed

  • BREAKING: meta::is_valid now panics for unknown $schema values instead of defaulting to Draft 2020-12. meta::validate returns an error for unknown $schema values. Use meta::options().with_registry() to validate schemas against custom meta-schemas.
  • BREAKING: Resource::from_contents no longer returns Result and always succeeds, since draft detection no longer fails for unknown $schema values.

Removed

  • BREAKING: meta::try_is_valid and meta::try_validate. Use meta::is_valid and meta::validate instead.
  • BREAKING: primitive_type module (deprecated since 0.30.0). Use jsonschema::types instead.

Performance

  • required: short-circuit when the instance object has fewer properties than required keys.

0.34.0 - 2025-11-14

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()).

0.33.0 - 2025-08-24

Fixed

  • BREAKING: instance_path segments are now unescaped when iterating. LocationSegment::Property now holds Cow<'_, str> and LocationSegment is no longer Copy. #788

0.32.1 - 2025-08-03

Changed

  • Bump fancy-regex to 0.16.

0.32.0 - 2025-07-29

0.31.0 - 2025-07-28

Added

  • CLI: flag -d, --draft <4|6|7|2019|2020> to enforce a specific JSON Schema draft.
  • CLI: flags --assert-format and --no-assert-format to toggle validation of format keywords.
  • Added context for ValidationErrorKind::AnyOf and ValidationErrorKind::OneOfNotValid which contains errors for all subschemas, each inside a separate vector with an index matching subschema ID.

Fixed

  • Improve the precision of multipleOf for float values.

Changed

  • Bump fancy-regex to 0.15.

0.30.0 - 2025-04-16

Added

Fixed

  • CLI: Inability to load relative file $ref. #725

Removed

  • Internal cache for regular expressions.

Deprecated

  • PrimitiveType and PrimitiveTypesBitMap.

0.29.1 - 2025-03-27

Added

  • Hash, PartialOrd, Ord and serde::Serialize for Location.
  • Make Location::join public.

0.29.0 - 2025-02-08

Breaking Changes

  • All builder methods on ValidationOptions now take ownership of self instead of &mut self. This change enables better support for non-blocking retrieval of external resources during the process of building a validator. Update your code to chain the builder methods instead of reusing the options instance:

    // Before (0.28.x)
let mut options = jsonschema::options();
options.with_draft(Draft::Draft202012);
options.with_format("custom", my_format);
let validator = options.build(&schema)?;

// After (0.29.0)
let validator = jsonschema::options()
    .with_draft(Draft::Draft202012)
    .with_format("custom", my_format)
    .build(&schema)?;

  • The Retrieve trait's retrieve method now accepts URI references as &Uri<String> instead of &Uri<&str>. This aligns with the async version and simplifies internal URI handling. The behavior and available methods remain the same, this is purely a type-level change.

    // Before
fn retrieve(&self, uri: &Uri<&str>) -> Result<Value, Box<dyn std::error::Error + Send + Sync>>

// After
fn retrieve(&self, uri: &Uri<String>) -> Result<Value, Box<dyn std::error::Error + Send + Sync>>

  • Simplified Registry creation API:

    • Removed RegistryOptions::try_new and RegistryOptions::try_from_resources in favor of Registry::build
    • Removed Registry::try_with_resource_and_retriever - use Registry::options().retriever() instead
    • Registry creation is now consistently done through the builder pattern
    // Before (0.28.x)
let registry = Registry::options()
    .draft(Draft::Draft7)
    .try_new(
        "http://example.com/schema",
        resource
    )?;

let registry = Registry::options()
    .draft(Draft::Draft7)
    .try_from_resources([
        ("http://example.com/schema", resource)
    ].into_iter())?;
  
let registry = Registry.try_with_resource_and_retriever(
    "http://example.com/schema",
    resource,
    retriever
)?;

// After (0.29.0)
let registry = Registry::options()
    .draft(Draft::Draft7)
    .build([
        ("http://example.com/schema", resource)
    ])?;

let registry = Registry::options()
    .draft(Draft::Draft7)
    .build([
        ("http://example.com/schema", resource)
    ])?;

let registry = Registry::options()
    .retriever(retriever)
    .build(resources)?;

Removed

  • CompilationError. Use ValidationError instead.

Fixed

  • The format validator incorrectly rejecting supported regex patterns. #230

0.9.0 - 2021-05-07

Added

Performance

  • Avoid String allocation in JSONPointer.into_vec.
  • Replace heap-allocated InstancePath with stack-only linked list.

0.8.0 - 2021-04-27

Changed

  • The propertyNames validator now contains the parent object in its instance attribute instead of individual properties as strings.
  • Improved error message for the additionalProperties validator. After - Additional properties are not allowed ('faz' was unexpected), before - False schema does not allow '"faz"'.
  • The additionalProperties validator emits a single error for all unexpected properties instead of separate errors for each unexpected property.
  • Breaking: ValidationError.instance_path is now a separate struct, that can be transformed to Vec<String> or JSON Pointer of type String.

Fixed

  • All instance_path attributes are pointing to the proper location.

0.7.0 - 2021-04-27

Added

  • ValidationError.instance_path that shows the path to the erroneous part of the input instance. It has the Vec<String> type and contains components of the relevant JSON pointer.
