Sourced from jsonschema's releases.

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 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.
