- 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.

**BREAKING CHANGES:**

### [`v1.9.2`](https://togithub.com/pydantic/pydantic/blob/HEAD/HISTORY.md#v192-2022-08-11)
[Compare Source](https://togithub.com/pydantic/pydantic/compare/v1.9.1...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](https://togithub.com/pydantic/pydantic/pull/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'`,

See [#4092](https://togithub.com/pydantic/pydantic/pull/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'`, [#4093](https://togithub.com/pydantic/pydantic/pull/4093) by [@timkpaine](https://togithub.com/timkpaine)
