Release Notes

python-jsonschema/jsonschema (jsonschema)

### [`v4.21.1`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4211) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.21.0...v4.21.1) \======= - Slightly speed up the `contains` keyword by removing some unnecessary validator (re-)creation. ### [`v4.21.0`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4210) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.20.0...v4.21.0) \======= - Fix the behavior of `enum` in the presence of `0` or `1` to properly consider `True` and `False` unequal ([#​1208](https://togithub.com/python-jsonschema/jsonschema/issues/1208)). - Special case the error message for `{min,max}{Items,Length,Properties}` when they're checking for emptiness rather than true length. ### [`v4.20.0`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4200) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.19.2...v4.20.0) \======= - Properly consider items (and properties) to be evaluated by `unevaluatedItems` (resp. `unevaluatedProperties`) when behind a `$dynamicRef` as specified by the 2020 and 2019 specifications. - `jsonschema.exceptions.ErrorTree.__setitem__` is now deprecated. More broadly, in general users of `jsonschema` should never be mutating objects owned by the library. ### [`v4.19.2`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4192) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.19.1...v4.19.2) \======= - Fix the error message for additional items when used with heterogeneous arrays. - Don't leak the `additionalItems` keyword into JSON Schema draft 2020-12, where it was replaced by `items`. ### [`v4.19.1`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4191) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.19.0...v4.19.1) \======= - Single label hostnames are now properly considered valid according to the `hostname` format. This is the behavior specified by the relevant RFC (1123). IDN hostname behavior was already correct. ### [`v4.19.0`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4190) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.18.6...v4.19.0) \======= - Importing the `Validator` protocol directly from the package root is deprecated. Import it from `jsonschema.protocols.Validator` instead. - Automatic retrieval of remote references (which is still deprecated) now properly succeeds even if the retrieved resource does not declare which version of JSON Schema it uses. Such resources are assumed to be 2020-12 schemas. This more closely matches the pre-referencing library behavior. ### [`v4.18.6`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4186) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.18.5...v4.18.6) \======= - Set a `jsonschema` specific user agent when automatically retrieving remote references (which is deprecated). ### [`v4.18.5`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4185) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.18.4...v4.18.5) \======= - Declare support for Py3.12 ### [`v4.18.4`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4184) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.18.3...v4.18.4) \======= - Improve the hashability of wrapped referencing exceptions when they contain hashable data. ### [`v4.18.3`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4183) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.18.2...v4.18.3) \======= - Properly preserve `applicable_validators` in extended validators. Specifically, validators extending early drafts where siblings of `$ref` were ignored will properly ignore siblings in the extended validator. ### [`v4.18.2`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4182) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.18.1...v4.18.2) \======= - Fix an additional regression with the deprecated `jsonschema.RefResolver` and pointer resolution. ### [`v4.18.1`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4181) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.18.0...v4.18.1) \======= - Fix a regression with `jsonschema.RefResolver` based resolution when used in combination with a custom validation dialect (via `jsonschema.validators.create`). ### [`v4.18.0`](https://togithub.com/python-jsonschema/jsonschema/blob/HEAD/CHANGELOG.rst#v4180) [Compare Source](https://togithub.com/python-jsonschema/jsonschema/compare/v4.17.3...v4.18.0) \======= This release majorly rehauls the way in which JSON Schema reference resolution is configured. It does so in a way that *should* be backwards compatible, preserving old behavior whilst emitting deprecation warnings. - `jsonschema.RefResolver` is now deprecated in favor of the new `referencing library `\_. `referencing` will begin in beta, but already is more compliant than the existing `$ref` support. This change is a culmination of a meaningful chunk of work to make `$ref` resolution more flexible and more correct. Backwards compatibility *should* be preserved for existing code which uses `RefResolver`, though doing so is again now deprecated, and all such use cases should be doable using the new APIs. Please file issues on the `referencing` tracker if there is functionality missing from it, or here on the `jsonschema` issue tracker if you have issues with existing code not functioning the same, or with figuring out how to change it to use `referencing`. In particular, this referencing change includes a change concerning *automatic* retrieval of remote references (retrieving `http://foo/bar` automatically within a schema). This behavior has always been a potential security risk and counter to the recommendations of the JSON Schema specifications; it has survived this long essentially only for backwards compatibility reasons, and now explicitly produces warnings. The `referencing` library itself will *not* automatically retrieve references if you interact directly with it, so the deprecated behavior is only triggered if you fully rely on the default `$ref` resolution behavior and also include remote references in your schema, which will still be retrieved during the deprecation period (after which they will become an error). - Support for Python 3.7 has been dropped, as it is nearing end-of-life. This should not be a "visible" change in the sense that `requires-python` has been updated, so users using 3.7 should still receive `v4.17.3` when installing the library. - On draft 2019-09, `unevaluatedItems` now properly does *not* consider items to be evaluated by an `additionalItems` schema if `items` is missing from the schema, as the specification says in this case that `additionalItems` must be completely ignored. - Fix the `date` format checker on Python 3.11 (when format assertion behavior is enabled), where it was too liberal ([#​1076](https://togithub.com/python-jsonschema/jsonschema/issues/1076)). - Speed up validation of `unevaluatedProperties` ([#​1075](https://togithub.com/python-jsonschema/jsonschema/issues/1075)). ## Deprecations - `jsonschema.RefResolver` -- see above for details on the replacement - `jsonschema.RefResolutionError` -- see above for details on the replacement - relying on automatic resolution of remote references -- see above for details on the replacement - importing `jsonschema.ErrorTree` -- instead import it via `jsonschema.exceptions.ErrorTree` - importing `jsonschema.FormatError` -- instead import it via `jsonschema.exceptions.FormatError`
