  • Refactor the whole pydantic dataclass decorator to really act like its standard lib equivalent.
    It hence keeps __eq__, __hash__, ... and makes comparison with its non-validated version possible.
    It also fixes usage of frozen dataclasses in fields and usage of default_factory in nested dataclasses.
    The support of Config.extra has been added.
    Finally, config customization directly via a dict is now possible, #2557 by @PrettyWood
    BREAKING CHANGES:
    • The compiled boolean (whether pydantic is compiled with cython) has been moved from main.py to version.py
    • Now that Config.extra is supported, dataclass ignores by default extra arguments (like BaseModel)
  • Fix PEP487 __set_name__ protocol in BaseModel for PrivateAttrs, #4407 by @tlambert03
  • Rename master to main, #4405 by @hramezani
  • Fix StrictStr does not raise ValidationError when max_length is present in Field, #4388 by @hramezani
  • Make SecretStr and SecretBytes hashable, #4387 by @chbndrhnns
  • Fix StrictBytes does not raise ValidationError when max_length is present in Field, #4380 by @JeanArhancet
  • Add support for bare type, #4375 by @hramezani
  • Support Python 3.11, including binaries for 3.11 in PyPI, #4374 by @samuelcolvin
  • Add support for re.Pattern, #4366 by @hramezani
  • Fix __post_init_post_parse__ is incorrectly passed keyword arguments when no __post_init__ is defined, #4361 by @hramezani
  • Fix implicitly importing ForwardRef and Callable from pydantic.typing instead of typing and also expose MappingIntStrAny, #4358 by @aminalaee
  • remove Any types from the dataclass decorator so it can be used with the disallow_any_expr mypy option, #4356 by @DetachHead
  • moved repo to pydantic/pydantic, #4348 by @yezz123
  • fix "extra fields not permitted" error when dataclass with Extra.forbid is validated multiple times, #4343 by @DetachHead
  • Add Python 3.9 and 3.10 examples to docs, #4339 by @Bobronium
  • Discriminated union models now use oneOf instead of anyOf when generating OpenAPI schema definitions, #4335 by @MaxwellPayne
  • Allow type checkers to infer inner type of Json type. Json[list[str]] will be now inferred as list[str],
    Json[Any] should be used instead of plain Json.
    Runtime behaviour is not changed, #4332 by @Bobronium
  • Allow empty string aliases by using a alias is not None check, rather than bool(alias), #4253 by @SergeyTsaplin
  • Update ForwardRefs in Field.outer_type_, #4249 by @JacobHayes
  • The use of __dataclass_transform__ has been replaced by typing_extensions.dataclass_transform, which is the preferred way to mark pydantic models as a dataclass under PEP 681, #4241 by @multimeric
