Stranger6667/jsonschema (jsonschema)

v0.58.2

Fixed
  • $dynamicRef targets in another document resolving relative references and reporting absolute keyword locations against the referencing document.
  • $ref to an $anchor or fragment $id validating against another anchor in the same document. #​1668
  • schema_path of errors under a $ref or $dynamicRef to a named schema pointing at the resource root instead of that schema.

v0.58.1

Fixed
  • Crash in Pyo3 validators when an Enum member's value override emptied a list or dict holding the instance being read.
Performance
  • uri and uri-reference formats check the syntax directly instead of parsing each value into a URI.
  • Enum members read their stored value directly instead of calling the value property in Pyo3 validators.

v0.58.0

Added
  • backend = Pyo3 on #[jsonschema::validator], generating a validator that reads Python objects in place.
  • backend = Magnus on #[jsonschema::validator], generating a validator that reads Ruby objects in place.
  • jsonschema::meta::pyo3, the bundled meta-schema validators for a schema held as a Python object.
  • jsonschema::meta::magnus, the bundled meta-schema validators for a schema held as a Ruby object.
  • methods = { ... } on #[jsonschema::validator], selecting which of is_valid, validate, and iter_errors are generated.
  • json::Jsonb, validating a Postgres jsonb value in place, behind the jsonb feature.
Performance
  • oneOf and anyOf whose branches each require a property fixed to a distinct string validate only the branch matching the instance's value.
  • Generated validate checks required in the same pass over an object as properties, instead of looking up each required name.
Fixed
  • A oneOf over $ref branches beside a sibling none of them admits, which canonicalized to an allOf instead of false.
  • multipleOf incorrectly accepted 1e-400 and other magnitudes below the smallest f64 subnormal with arbitrary-precision (they are not zero).
  • Numeric keywords panicked on a custom representation holding a number past f64 without arbitrary-precision.

v0.57.0

Added
  • PreparedDocument::unsatisfiable, naming the keywords that leave each unsatisfiable subschema empty and where they are.
Changed
  • PreparedDocument::unsatisfiable_pointers is replaced by PreparedDocument::unsatisfiable.
Fixed
  • The instance path of a schema build error, which was empty instead of naming the keyword location that failed to compile.
  • PreparedDocument::unsatisfiable_pointers passed over a subschema that admits no value only once its references resolve, such as an allOf over two $refs.
Performance
  • Canonicalizing several subschemas of one prepared document parses each definition body once for the document instead of once per call.

v0.56.0

Added
  • canonical::RawReason, what stopped a run from modeling a document, and canonical::RawView, carrying it beside the document and a pointer to the subschema the run stopped on.
  • ValidationOptions::is_known_format, whether a format of that name is checked under a draft.
Changed
  • BREAKING: canonical::CanonicalView::Raw carries a canonical::RawView in place of the document alone.
  • Canonicalization of a oneOf whose branches share a region too wide to expand, which spent the document's whole intersection allowance on that choice and kept the document Raw.
Performance
  • Preparing or building a schema that names no base URI parses the default one once for the process instead of once per schema.
  • Canonicalizing several subschemas of one prepared document compiles each pattern once for the document instead of once per call.
  • Canonicalization reads the facets no checker covers once per node instead of once per containment query.

v0.55.1

Changed
  • Canonicalization of an anyOf over an allOf through a $ref to a union, which left that union nested inside the outer one.
  • Canonicalization of an anyOf whose branch narrowing runs out of intersections, which left true as a branch inside the union.

v0.55.0

Changed
  • BREAKING: canonical::ObjectViolationView gained the PatternValueFails variant, which negation records for a patternProperties entry.
  • Canonicalization of not over patternProperties, which kept the entry under not instead of recording the demand a key breaks.
  • Canonicalization of unevaluated* beside a conditional reaching no key or index the node already evaluates, which spent a case on it.
  • Canonicalization of a conditional split outgrowing its per-node case budget, which kept documents like the Open API 3.2 meta-schema Raw.
  • Canonicalization of an anyOf over objects sharing a properties key under patternProperties, which settled only on a second pass.
  • Canonicalization of not over an allOf folded through a reference, which settled only on a second pass.
  • Canonicalization of a multipleOf divisor past f64 precision, which was not taken to divide itself.
  • Canonicalization of an anyOf over a value beside a window pinned to it, which settled only on a second pass.
  • Canonicalization of minProperties: 1 beside a not that already demands a key, which settled only on a second pass.
Fixed
  • absolute_keyword_location naming the sibling keyword whose validator carries the check: maxLength beside minLength, minItems, maxItems or type beside items, and a two-name required beside properties. #​1579
  • schemaLocation in evaluate output naming minLength for a maxLength failure. #​1579

v0.54.0

Added
  • backend = SerdeJson on #[jsonschema::validator], generating a validator that reads serde_json::Value.
  • PreparedDocument::unsatisfiable_pointers, listing every subschema no value satisfies.
Changed
  • Canonicalization of unevaluated* beside dependentSchemas or if/then/else, which kept the document Raw.
  • Canonicalization of not over patternProperties, which kept the document Raw.
Performance
  • validate and iter_errors check each assertion keyword with the is_valid path and build an error only for a failing one.
  • evaluate holds its output tree in one allocation instead of one per node.
  • A pattern of ^\S*$ scans bytes instead of decoding every character.
  • validate on properties beside a two-name required confirms both names in the pass that checks the properties, instead of looking each up first.
  • A string enum compares an option's length and first and last eight bytes before its full text.
  • A JSON Pointer segment is scanned for ~ and / eight bytes at a time before it is copied.
  • Canonicalization cloning leaves per intersection and the definition map per settled target.
Fixed
  • type: array with items and minItems/maxItems checking the built-in length bound even when a custom keyword overrides minItems or maxItems, so the bound was evaluated twice.
  • A custom keyword overriding type, required or maxLength not replacing the built-in check for that keyword.
  • A custom keyword overriding items, minLength, properties or additionalProperties leaving its sibling keywords unchecked.
  • #[jsonschema::validator] generated code that named serde_json directly, so it needed the consumer crate to depend on serde_json too.
  • Canonicalization of not over an object with properties, patternProperties and additionalProperties, which applied additionalProperties to the keys listed in properties.

v0.53.0

Added
  • Location::segments, iterating the segments without collecting them.
  • CanonicalizeOptions::prepare, canonicalizing any number of a document's subschemas by JSON Pointer, with the document indexed once.
  • CLI: the --at POINTER flag of jsonschema canonicalize, canonicalizing only the subschema at that pointer without breaking its references into the rest of the document.
  • CLI: jsonschema canonicalize reads YAML schemas (.yaml/.yml) as well as JSON.
  • canonical::{ArrayView, IntegerView, NumberView, ObjectView, StringView, TypedGroupView}, the payload types of CanonicalView, so consumers can name them in signatures.
Fixed
  • jsonschema-value failing to build with default-features = false.
  • jsonschema-value failing to build for wasm32-unknown-unknown, which needs getrandom's wasm_js backend.
  • Draft 4 type: integer accepting numbers written with an exponent, like 1e2.
  • Draft 4 type: integer answering differently for the same number across representations.
  • uniqueItems accepting 0 alongside -0.0 in arrays of more than 15 items.
Performance
  • Canonicalizing an allOf of object schemas walks their property maps once instead of looking every key up.
  • properties and required compare short names without memcmp.
  • Building a schema is up to 5% faster, from cheaper cache sharing and resolving each $ref target once.
  • Building a schema with an $id is up to 15% faster, from encoding each absolute location once.
  • required scans small objects once instead of looking up each key.
  • enum listing strings or integers, with or without null, matches against a set instead of comparing each candidate.
  • evaluate is up to 33% faster, from rendering each node's locations once.
  • CLI: 1.4-1.5x faster on large schemas, from reading files before parsing them.
  • Draft 4 type: integer with arbitrary-precision no longer allocates a string per number.
  • type: integer, and type sets containing it, are up to 54x faster on float-heavy instances with arbitrary-precision.
  • Draft 4 type: integer is up to 20x faster for the Pyo3 and Magnus representations.

v0.52.1

Fixed
  • multipleOf rejecting valid values like 1070468.14 for 0.01 without arbitrary-precision.
Performance
  • minLength and maxLength together now scan the string once.
  • multipleOf with a fractional divisor is 8-16x faster.
  • unevaluatedProperties is up to 2.9x faster.
  • evaluate is up to 27% faster on reference-heavy schemas.

v0.52.0

Added
  • Evaluation::is_valid.
  • Location::is_empty.
  • Display for ErrorEntry.
  • ValidationOptions::offline and canonical::CanonicalizeOptions::offline, refusing to fetch references outside the registry.
  • idna Cargo feature, enabled by default, gating the idn-hostname and idn-email formats. #​1313
  • CLI: the --offline flag of jsonschema validate, jsonschema bundle and jsonschema dereference.
Changed
  • ValidationErrors' Display gained the instance path of each error.
  • BREAKING: With default-features = false, the idn-hostname and idn-email formats now require the new idna feature. Without it they are unknown formats, which are accepted by default, or rejected at build time under should_ignore_unknown_formats(false). Add idna to the feature list to keep the previous behavior.
Fixed
  • Canonicalization not idempotent where a patternProperties $ref matches a key properties names.
  • is_valid disagreeing with validate, iter_errors, and evaluate on a schema that reaches its own $ref twice, one of them under not.
  • format: email and format: idn-email rejecting an empty quoted string as the local part (it should be accepted).
  • format: email and format: idn-email rejecting an address literal whose IPv6: tag is not written in that exact case (the tag is case-insensitive).
  • format: email accepting a non-ASCII character in the local part (it should be rejected).
  • ValidationOptions::with_draft gating keywords on the vocabularies of the $schema it overrides, so the validator accepted every instance.
Performance
  • iter_errors collects into a single buffer instead of allocating and re-boxing an iterator at every schema node.

v0.51.0

Added
  • ValidationOptions::with_vocabulary and the vocabularies attribute on jsonschema::validator, declaring support for a vocabulary this crate does not implement.
  • The --vocabulary flag of jsonschema validate.
Changed
  • Vocabulary gained the FormatAssertion variant, which its Draft 2020-12 URI parses to instead of Vocabulary::Custom, and is marked non_exhaustive.
Fixed
  • The uniqueItems length ceiling not reading an items or contains schema written as a $ref.
  • The Draft 2020-12 Format-Assertion vocabulary read as an annotation, so a meta-schema requiring it accepted values its format rejects.
  • An unrecognized format accepted under a meta-schema requiring the Format-Assertion vocabulary (it should be rejected).
  • A meta-schema requiring a vocabulary this crate does not implement accepted (it should be rejected).
  • The Draft 2019-09 Format vocabulary declared true read as an annotation, so a meta-schema requiring it accepted values its format rejects.
  • The bundled https://json-schema.org/draft/2020-12/meta/format-assertion meta-schema not declaring its vocabulary, so a schema written against it annotated format instead of asserting it.
  • A meta-schema without $id keeping its $vocabulary unread, so a schema written against it got every Draft 2020-12 vocabulary.
  • A schema naming a bundled vocabulary meta-schema as its $schema rejected as an unknown meta-schema (it should build).
  • The regex format reading the Rust regex dialect (it should read the ECMA-262 dialect in Unicode mode).
  • The uri-template format rejecting an apostrophe in a literal (it should accept it, per RFC 6570 errata 6937).
  • The duration format accepting weeks combined with a time part, such as P1WT1H (it should reject it).
  • Stack overflow compiling unevaluatedProperties or unevaluatedItems beside a $ref that cycles back to the node, written as #, through its $id, or through a chain of definitions.
Performance
  • Building unevaluatedProperties or unevaluatedItems over a deep allOf or $ref chain costs its depth instead of its square.

v0.50.1

Changed
  • CanonicalSchema::satisfiability answers Yes for a string whose pattern or format a matching value can be built from.
  • CanonicalSchema::satisfiability answers No where a format takes no string of the length the schema asks for.
Fixed
  • CanonicalSchema::negate taking apart a union that reads a definition through its own if, so a schema and its negation shared a value.
  • CanonicalSchema::subtract dropping a Draft 4 array member an element demand partly takes.
  • CanonicalSchema::covers answering Yes where a Draft 4 element demand refuses a member.
  • A string schema whose maxLength is 0 keeping a pattern, format, or content facet unread, so the same constraints written in one object and written as an allOf reached different canonical forms.
Performance
  • not over a wide object schema costs its branch count instead of its square.
  • not over an object schema is linear in its property count, not quadratic.
  • not over an object schema with additionalProperties: false no longer costs cubic time in its property count.

v0.50.0

Added
  • CanonicalSchema::union and CanonicalSchema::subtract.
  • CanonicalizationError::UnsupportedResult, reported where the canonical form does not support a set operation's result.
  • OperandMismatch::DocumentRoots, reported where both operands read # and it names a different document on each side.
  • CLI: jsonschema validate -i INSTANCE without a SCHEMA argument validates each instance against the schema named in its own $schema property. #​1470
Changed
  • CanonicalSchema::is_satisfiable is now CanonicalSchema::satisfiability, answering Yes, No, or Unknown - Yes wherever a value can be exhibited, not only for the forms listing their members.
  • CanonicalSchema::covers decides through the difference as well: No where the argument keeps values the receiver rejects, Yes where nothing is left over.
  • CanonicalSchema::is_subset_of is now CanonicalSchema::covers, answering Yes, No, or Unknown for whether the receiver admits every value the argument admits.
  • CanonicalSchema::negate returns Result rather than Option.
  • CanonicalizationError::UnmodeledOperand is now CanonicalizationError::UnsupportedOperand, and means only that an operand is a Raw pass-through.
  • A conjunction over a $ref folds through the body it names, so canonicalizing a document and combining its parts with the set operations reach one form; a document holding a reference cycle keeps the form it had.
Fixed
  • Combining nodes of two different documents repointing a $ref to # at the combined result instead of the document it was written in, including one named by a definition the result keeps.
  • Intersecting a $ref whose target is true or false, which panicked.
  • A key constraint left un-narrowed once a run is out of intersections, which panicked on the next read of it.
  • CanonicalSchema::covers answering Unknown for a schema against itself, where that schema is a $ref.
  • CanonicalSchema::union keeping a $ref beside the schema it names, where the other three operations read through it.
  • CanonicalSchema::covers and CanonicalSchema::subtract cancelling two nodes written the same way whose # names a different document.
  • Two results accepting the same values comparing unequal over the part of their documents neither reads.
  • additionalProperties reaching a key the pattern map matches when a finite key constraint closes the map, which dropped values both operands accept.
  • A recursive definition stopping every other pointer in the document from being read through.
  • One $defs entry read past a wider schema written out at every use, rather than kept as the pointer it was.
  • Set operations rejecting one document canonicalized twice, and a pruned result rejected against the document it came from, where the maps resolve every shared reference the same way.
  • Set operations comparing a $ref as a pointer instead of reading through it, so a schema written with a $ref did not cancel against the same schema written out.
  • CanonicalSchema::subtract asking for a complement where the difference is one of the operands or empty, declining on schemas it can subtract.
  • Set operations keeping $defs entries the result no longer references, which then showed up in the emitted schema.
  • CanonicalSchema::union declining over an approximated intersection, where the union itself is exact.
  • Resolving a reference against a base URI that carries a fragment, which happens when a Draft 4-7 $id contains one. #​1473
  • unevaluatedProperties and unevaluatedItems ignoring an $id on a subschema they walk through, so a relative $ref inside it resolved against the enclosing resource.
Performance
  • CLI: ~25% less CPU per run from compile-time meta-schema validators.

v0.49.9

Added
  • Canonicalization of a oneOf whose branches name object targets a required constant tells apart, which degrades to a union.
Changed
  • CanonicalSchema::to_json_schema on a definition emits only the definitions that one names, not the whole document's.
Fixed
  • Canonicalization running without end on a conjunction over unions; past a ceiling on the meets it takes, the document stays unmodeled.

v0.49.8

Performance
  • Up to 380x faster canonicalization of a oneOf whose overlapping branches carry many properties, which no longer removes shared regions the exactly-one spelling discards.
Fixed
  • Draft detection treating the version-less http://json-schema.org/schema meta-schema URI as a custom dialect, where it names the current draft.
  • A patternProperties entry matching every key leaving additionalProperties: false spelled as a key constraint, where it forbids nothing.
  • unevaluatedProperties/unevaluatedItems set to true forcing the whole document to stay unmodeled beside an unresolved applicator, where the keyword rejects nothing regardless of the evaluated set.
  • unevaluatedProperties/unevaluatedItems beside a $ref forcing the whole document to stay unmodeled, where the reference's own evaluated properties or items are known once it is resolved.

v0.49.7

Added
  • CanonicalizeOptions::with_retriever to fetch external resources absent from the registry.
  • CanonicalizeOptions::with_base_uri to resolve relative references in the root schema.
  • Canonicalization of a oneOf whose branches name disjoint targets, which degrades to a union.
  • Canonicalization of a vacuous patternProperties entry beside schema-valued additionalProperties, where matching keys escape its value constraint.
  • Canonicalization of a Draft 4 closed pattern map with a reference nested under a property.
  • Canonicalization of Draft 4 closed pattern maps that meet through an applicator.
  • The complement of a reference back to a target already being negated, which stays symbolic instead of declining.
  • CanonicalSchema::definition resolving # to the document the handle was read against.
Performance
  • Up to 150x faster canonicalization of not over a union of many branches.
  • 2% faster emission of canonical schemas, which no longer formats copied string values.
  • 5% faster emission of canonical schemas, which no longer formats object keys while copying them.
  • Up to 12% faster canonicalization of schemas that repeatedly intersect the same branches.
  • 13% faster canonicalization of a non-dynamic OpenAPI document, which no longer scans every schema object for dynamic references.
  • Faster canonicalization of schemas with local $defs references, which avoid decoding unescaped definition names.
  • 23% faster canonicalization of an object whose keys a finite property-name set spells.
  • 3% faster intersection of schemas where one side constrains nothing.
  • Up to 31x faster canonicalization of a oneOf whose many branches overlap.
  • Up to 14x faster canonicalization of a union whose object branches share no values.
  • 7% faster canonicalization of schemas that reach the same pair of nodes repeatedly.
  • 5% faster canonicalization of objects, whose property maps no longer reach the allocator.
  • Up to 8% faster canonicalization of schemas that reach true and false subschemas repeatedly.
  • 2% faster canonicalization of schemas that assert known string formats.
Fixed
  • CanonicalSchema::definition and CanonicalSchema::definitions handing out a target that names the document root without that document, where # points at the target instead.
  • An items tail beyond an array's length ceiling surviving canonicalization, where it governs no element.
  • CanonicalSchema::to_json_schema leaving the document root out of a node emitted below it, where # points at that node instead.

v0.49.6

Added
  • Canonicalization of a negated uniqueItems, where the complement demands a repeated element under the length floor two elements imply.
  • Canonicalization of a negated array tuple, where each position's complement stands under the length that reaches it.
  • Canonicalization of contains demands sharing no value, where their counts add up into a length floor.
  • CanonicalSchema::negate through references, where the complement of the resolved target takes the reference's place.
  • Canonicalization of negated propertyNames and additionalProperties, where the complement spells the violating-key demand instead of a not residual.
  • Canonicalization of negated additionalProperties under Draft 4, where the violating-key demand spells the closed property map.
  • Canonicalization of not a reference, where the complement of the resolved target takes the pointer's place.
  • Canonicalization of a negated oneOf, where the complement spells the values no branch admits beside the values two branches share.
  • Canonicalization of negated items under Draft 4, where the violating-element demand spells the barred element schema.
Changed
  • ArrayView reports distinctness in three states, so an array demanding a repeated element reads apart from one demanding distinct elements.
Fixed
  • CanonicalSchema::negate keeping a root self-reference in the complement, where it points at the complement instead of the source.
  • An additionalItems that tails no tuple keeping the whole document unmodeled under Draft 2020-12.

v0.49.5

Added
  • Canonicalization of not an integer schema under Draft 4, which the number leaf carries as barred integers.
  • Canonicalization of not a multipleOf, which numeric leaves carry as barred divisors.
  • Canonicalization of not an integer schema, where a barred divisor of one spells the non-integer numbers.
  • Canonicalization of not a pattern, which string leaves carry as barred patterns.
  • Canonicalization of not a typed value set under Draft 4, such as {"type": "integer", "enum": [1, 2]}.
  • CanonicalSchema::is_subset_of, whether the other schema admits every value this one admits.
  • Canonicalization of a reference cycle carrying no assertion, which admits every value.
Fixed
  • CanonicalSchema::is_subset_of failing to prove a union of array branches a subset of itself.
  • CanonicalSchema::intersect admitting values one side rejects when its additionalProperties governs the keys the other side's patternProperties match.
  • A satisfiable multipleOf schema collapsing to the empty set when f64 rounds its bounds together.
  • Two spellings of one number canonicalizing to different texts under arbitrary-precision when the fraction exceeds the expansion cap.
  • Numeric bounds and multipleOf comparing values through a lossy f64 conversion under arbitrary-precision, such as 1e-400 passing {"maximum": 0}.
  • A union branch left unabsorbed when a sibling complement shed a conjunct from another branch.
  • A union keeping an integer branch beside a number branch that admits every value of it.

v0.49.4

Added
  • Canonicalization of not a string format, which the string leaf carries as barred formats.
  • Canonicalization of not an existential demand, which an array fails exactly when no element matches.
  • Canonicalization of not a string value set, which the string leaf carries as excluded values.
  • Canonicalization of unevaluatedItems beside contains, where the elements it matches are evaluated and the tail admits either.
  • Canonicalization of unevaluated* beside anyOf or oneOf, where every branch evaluating the same keys or indexes pins what is left over.
  • Canonicalization of not an array element schema, which an array fails exactly when one element violates it.
  • CanonicalSchema::intersect, the values both schemas admit.
  • CanonicalSchema::negate, the values a schema rejects.
  • CanonicalSchema::definition, one reference target by URI.
Fixed
  • An integer past i64 admitted by a fractional bound f64 rounds it onto, such as -10000000000000000000000000 under {"maximum": -10000000000000000000000000.1}.
  • An integer past 2^53 admitted by a bound f64 rounds onto it, such as 9007199254740992 under {"minimum": 9007199254740993}.
  • A contains subschema beside both minContains and maxContains overwriting a sibling keyword of the same name, such as items.
Performance
  • CanonicalSchema hashing and equality cost the node instead of the whole document.

v0.49.3

Added
  • Canonicalization of a recursive schema with no finite witness, which now folds to false.
  • Canonicalization of $dynamicRef and $recursiveRef, which resolve through the dynamic scope and stay symbolic like any other reference. A dangling $dynamicRef errors rather than staying Raw.
  • Canonicalization of minContains under uniqueItems, where a demand asking for more matches than its own schema has distinct values now folds to false.
  • Canonicalization of a Draft 4 patternProperties coverage closed by additionalProperties: false, spelled as the closed map it was parsed from.
  • Canonicalization of a oneOf whose branches repeat, where a repeated branch can never contribute exactly one match.
  • Canonicalization of a $ref whose target is an empty schema, which now folds to false.
  • Canonicalization of unevaluatedItems beside allOf, where every branch must pass and so the indexes they evaluate are known without the instance.
  • Canonicalization of unevaluatedProperties beside allOf, where every branch must pass and so what they evaluate is known without the instance.
  • Canonicalization of a Draft 4 type list holding integer beside other types with enum, which previously modeled only when spelled as an allOf.
  • Canonicalization of patternProperties patterns matching finitely many keys, such as ^a$ and ^(a|b)$.
  • Canonicalization of unevaluatedProperties and unevaluatedItems when no in-place applicator sits beside them.
Fixed
  • additionalItems values that are not schemas silently ignored beside an array-form items (they should fail the build like additionalProperties).
  • additionalItems beside a boolean items rejecting every instance, such as {"additionalItems": false, "items": false}.
  • additionalItems beside a non-array items value failing schema compilation with an error blaming additionalItems (the keyword should be ignored).
  • Draft 4 rejecting a size bound at or past 2^64, such as {"maxItems": 18446744073709551616}.
  • An integer past the f64 range admitted by a fractional bound it exceeds, such as 1e400 under {"exclusiveMaximum": 0.1}.
  • A $ref at the root of an $id-bearing subresource dropped as a self-reference when its pointer matched the one that reached that subresource.
  • Canonicalization reusing one definition's body for a same-named definition in another resource, when the name spells a canonical URI.
  • unevaluatedItems counting prefixItems as evaluating elements before Draft 2020-12, where it is not a keyword.
Performance
  • Up to 70% faster evaluate by building each location in a single allocation instead of two, reusing the instance location a node already built, and caching evaluation paths across instance nodes.

v0.49.2

Performance
  • Faster serialization of canonicalized schemas.
  • Faster macro code generation for subschemas with many keywords.
  • Up to 70x faster canonicalization of multipleOf beside numeric bounds far from zero.

v0.49.1

Fixed
  • jsonschema-value: Ruby builds on x64-mingw-ucrt.

v0.49.0

Added
  • Generic JSON input: options_for builds a validator over any instance representation implementing json::Json, so instances validate without conversion to serde_json::Value. #​239
  • meta::validate_for and meta::is_valid_for for checking a schema document held in any representation implementing json::Json against its meta-schema.
  • EXPERIMENTAL: Schema canonicalization via jsonschema::canonicalize. It reduces a reasonable subset of JSON Schemas to their normal forms.
Fixed
  • multipleOf incorrectly accepted integers past u64 that are not multiples of the divisor.

v0.48.5

Fixed
  • Packaging issue again.

v0.48.2

Performance
  • Faster validator compilation by pre-sizing internal caches.

v0.48.1

Fixed
  • Missing required errors in evaluate() output for schemas with properties and a two-entry required array. #​1220
  • contentEncoding errors for invalid UTF-8 after decoding incorrectly had empty instance_path and schema_path.
Performance
  • Faster code generation for #[jsonschema::validator] (~5% across benchmarked schemas), via aliasing repeated paths in the emitted code.

v0.48.0

Added
  • iter_errors for #[jsonschema::validator]-generated validators.
Fixed
  • Per-branch context on generated anyOf and oneOf validation errors, matching runtime validators.
  • $recursiveRef in generated validators incorrectly resolved to the innermost $recursiveAnchor (it should resolve to the outermost one).
  • Integer instances just outside the i64/u64 range incorrectly compared against numeric bounds through lossy f64 rounding under arbitrary-precision (e.g. {"minimum": -9223372036854775808} accepted -9223372036854775809).
Changed
  • One canonical number spelling from canonical::json::to_string under arbitrary-precision ("1e-2" becomes "0.01", "1.50" becomes "1.5") and correctly-rounded float parsing (serde_json's float_roundtrip).
Performance
  • Faster multipleOf validation for integer instances with integer divisors, via integer arithmetic instead of floating-point modulo.

v0.47.0

Added
  • #[jsonschema::validator] attribute macro (behind the macros feature) that compiles a JSON Schema into is_valid and validate implementations at build time.
  • Keyword::iter_errors for reporting multiple validation errors from a single custom keyword. #​1071
Changed
  • Bump MSRV to 1.85.0.
Performance
  • Faster meta-schema validation and schema compilation with the macros feature, via compile-time meta-schema validators.
Fixed
  • type under items asserted with the Validation vocabulary disabled.
  • Disabled vocabularies ignored for $ref targets without their own $schema (e.g. $defs entries).

v0.46.10

Fixed
  • Stack overflow with a self-referential $dynamicRef combined with unevaluatedProperties or unevaluatedItems.
  • Incorrect unevaluatedProperties and unevaluatedItems results when a meta-schema disables the Applicator vocabulary.

v0.46.9

Fixed
  • multipleOf incorrectly rounds integer instances above 2^53 to f64 before the divisibility check on builds without the arbitrary-precision feature.
  • Stack overflow while preparing a registry containing deeply nested schema documents.

v0.46.8

Fixed
  • idn-email format rejected non-ASCII characters in quoted local parts (e.g. "δοκιμή"@example.com).

v0.46.7

Fixed
  • idn-hostname format accepted A-labels that decode to a disallowed code point (e.g. xn--7a).

v0.46.6

Added
  • IntoRegistryResource for Arc<Value>. #​1129
Fixed
  • prefixItems incorrectly recognised as a known keyword in Draft 2019-09 and earlier (it is 2020-12 only).
  • pattern validation errors displayed the internally translated regex instead of the original schema pattern. #​1149

v0.46.5

Fixed
  • Percent-encoded characters in $ref URI fragments (e.g. #/$defs/Request%20class) are now decoded when stored as schema_path.

v0.46.4

Fixed
  • Panic in the regex engine when matching against patterns with very large {0,N} quantifiers.

v0.46.3

Fixed
  • Memory not reclaimed when a Validator for a schema with recursive $ref or $dynamicRef is dropped. #​1125
  • Compilation failure on wasm32-wasip1 and wasm32-unknown-emscripten targets.

v0.46.2

Fixed
  • required not enforced when additionalProperties is a schema object and required lists exactly 2 keys.

v0.46.1

Fixed
  • Stack overflow with a self-referential $dynamicRef combined with unevaluatedProperties or unevaluatedItems.
  • Incorrect unevaluatedProperties and unevaluatedItems results when a meta-schema disables the Applicator vocabulary.

v0.46.0

Added
  • ValidatorMap for validating instances against subschemas identified by URI-fragment JSON pointer. #​1075
  • CLI: Accept multiple values after -i/--instance (e.g. jsonschema validate schema.json -i *.json). #​1085
  • dereference function to recursively inline $ref references. #​422
  • CLI: jsonschema dereference subcommand to dereference a schema from the command line.
Breaking Changes
  • Registry construction now uses an explicit prepare step, and with_registry now borrows the prepared registry. ValidationOptions::with_resource and ValidationOptions::with_resources were removed in favor of building a Registry first. See the Migration Guide for the details.
Performance
  • Avoid registry clones and document clones during validator construction. This improves real-world schema compilation by roughly 10-20% in internal benchmarks.

v0.45.1

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.

v0.45.0

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.

v0.44.1

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

v0.44.0

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.

v0.43.0

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.

v0.42.2

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

v0.42.1

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

v0.42.0

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 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 librari
