CHANGELOG.rst

v4.7.0

• Enhance best_match to prefer errors from branches of the schema which match the instance's type (#728)

v4.6.2

• Fix a number of minor typos in docstrings, mostly private ones (#969)

v4.6.1

• Gut the (incomplete) implementation of recursiveRef on draft 2019. It needs completing, but for now can lead to recursion errors (e.g. #847).

v4.6.0

• Fix unevaluatedProperties and unevaluatedItems for types they should ignore (#949)
• jsonschema now uses hatch for its build process. This should be completely transparent to end-users (and only matters to contributors).

v4.5.1

• Revert changes to $dynamicRef which caused a performance regression in v4.5.0

v4.5.0

• Validator classes for each version now maintain references to the correct corresponding format checker (#905)
• Development has moved to a GitHub organization. No functional behavior changes are expected from the change.

v4.4.0

• Add mypy support (#892)
• Add support for Python 3.11

v4.3.3

• Properly report deprecation warnings at the right stack level (#899)

v4.3.2

• Additional performance improvements for resolving refs (#896)

v4.3.1

• Resolving refs has had performance improvements (#893)

v4.3.0

• Fix undesired fallback to brute force container uniqueness check on certain input types (#893)
• Implement a PEP544 Protocol for validator classes (#890)

v4.2.1

• Pin importlib.resources from below (#877)

v4.2.0

• Use importlib.resources to load schemas (#873)
• Ensure all elements of arrays are verified for uniqueness by uniqueItems (#866)

v4.1.2

• Fix dependentSchemas to properly consider non-object instances to be valid (#850)

v4.1.1

• Fix prefixItems not indicating which item was invalid within the instance path (#862)

v4.1.0

• Add Python 3.10 to the list of supported Python versions

v4.0.1

• Fix the declaration of minimum supported Python version (#846)

v4.0.0

• Partial support for Draft 2020-12 (as well as 2019-09). Thanks to Thomas Schmidt and Harald Nezbeda.
• False and 0 are now properly considered non-equal even recursively within a container (#686). As part of this change, uniqueItems validation may be slower in some cases. Please feel free to report any significant performance regressions, though in some cases they may be difficult to address given the specification requirement.
• The CLI has been improved, and in particular now supports a --output option (with plain (default) or pretty arguments) to control the output format. Future work may add additional machine-parsable output formats.
• Code surrounding DEFAULT_TYPES and the legacy mechanism for specifying types to validators have been removed, as per the deprecation policy. Validators should use the TypeChecker object to customize the set of Python types corresponding to JSON Schema types.
• Validation errors now have a json_path attribute, describing their location in JSON path format
• Support for the IP address and domain name formats has been improved
• Support for Python 2 and 3.6 has been dropped, with python_requires properly set.
• multipleOf could overflow when given sufficiently large numbers. Now, when an overflow occurs, jsonschema will fall back to using fraction division (#746).
• jsonschema.__version__, jsonschema.validators.validators, jsonschema.validators.meta_schemas and jsonschema.RefResolver.in_scope have been deprecated, as has passing a second-argument schema to Validator.iter_errors and Validator.is_valid.

v3.2.0

• Added a format_nongpl setuptools extra, which installs only format dependencies that are non-GPL (#619).

v3.1.1

• Temporarily revert the switch to js-regex until #611 and #612 are resolved.

v3.1.0

• Regular expressions throughout schemas now respect the ECMA 262 dialect, as recommended by the specification (#609).

v3.0.2

• Fixed a bug where 0 and False were considered equal by const and enum (#575).

v3.0.1

• Fixed a bug where extending validators did not preserve their notion of which validator property contains $id information.

v3.0.0

• Support for Draft 6 and Draft 7
• Draft 7 is now the default
• New TypeChecker object for more complex type definitions (and overrides)
• Falling back to isodate for the date-time format checker is no longer attempted, in accordance with the specification

v2.6.0

• Support for Python 2.6 has been dropped.
• Improve a few error messages for uniqueItems (#224) and additionalProperties (#317)
• Fixed an issue with ErrorTree's handling of multiple errors (#288)

v2.5.0

• Improved performance on CPython by adding caching around ref resolution (#203)

v2.4.0

• Added a CLI (#134)
• Added absolute path and absolute schema path to errors (#120)
• Added relevance
• Meta-schemas are now loaded via pkgutil

v2.3.0

• Added by_relevance and best_match (#91)
• Fixed format to allow adding formats for non-strings (#125)
• Fixed the uri format to reject URI references (#131)

v2.2.0

• Compile the host name regex (#127)
• Allow arbitrary objects to be types (#129)

v2.1.0

• Support RFC 3339 datetimes in conformance with the spec
• Fixed error paths for additionalItems + items (#122)
• Fixed wording for min / maxProperties (#117)

v2.0.0

• Added create and extend to jsonschema.validators
• Removed ValidatorMixin
• Fixed array indices ref resolution (#95)
• Fixed unknown scheme defragmenting and handling (#102)

v1.3.0

• Better error tracebacks (#83)
• Raise exceptions in ErrorTrees for keys not in the instance (#92)
• __cause__ (#93)

v1.2.0

• More attributes for ValidationError (#86)
• Added ValidatorMixin.descend
• Fixed bad RefResolutionError message (#82)

v1.1.0

• Canonicalize URIs (#70)
• Allow attaching exceptions to format errors (#77)

v1.0.0

• Support for Draft 4
• Support for format
• Longs are ints too!
• Fixed a number of issues with $ref support (#66)
• Draft4Validator is now the default
• ValidationError.path is now in sequential order
• Added ValidatorMixin

v0.8.0

• Full support for JSON References
• validates for registering new validators
• Documentation

• Bugfixes

  • uniqueItems not so unique (#34)
  • Improper any (#47)

v0.7

• Partial support for (JSON Pointer) $ref
• Deprecations
  • Validator is replaced by Draft3Validator with a slightly different interface
  • validator(meta_validate=False)

v0.6

• Bugfixes
  • Issue #30 - Wrong behavior for the dependencies property validation
  • Fixed a miswritten test

v0.5

• Bugfixes
  • Issue #17 - require path for error objects
  • Issue #18 - multiple type validation for non-objects

v0.4

• Preliminary support for programmatic access to error details (Issue #5). There are certainly some corner cases that don't do the right thing yet, but this works mostly.

  In order to make this happen (and also to clean things up a bit), a number of deprecations are necessary:

  • stop_on_error is deprecated in Validator.__init__. Use Validator.iter_errors() instead.
  • number_types and string_types are deprecated there as well. Use types={"number" : ..., "string" : ...} instead.
  • meta_validate is also deprecated, and instead is now accepted as an argument to validate, iter_errors and is_valid.

• A bugfix or two

v0.3

• Default for unknown types and properties is now to not error (consistent with the schema).
• Python 3 support
• Removed dependency on SecureTypes now that the hash bug has been resolved.
• "Numerous bug fixes" -- most notably, a divisibleBy error for floats and a bunch of missing typechecks for irrelevant properties.
