v1.10.0

Compare Source

• 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

v1.9.2

Revert Breaking Change: v1.9.1 introduced a breaking change where model fields were
deep copied by default, this release reverts the default behaviour to match v1.9.0 and before,
while also allow deep-copy behaviour via copy_on_model_validation = 'deep'. See #​4092 for more information.

• Allow for shallow copies of model fields, Config.copy_on_model_validation is now a str which must be
  'none', 'deep', or 'shallow' corresponding to not copying, deep copy & shallow copy; default 'shallow',
