Marshmallow

*******************

Features:

- Replace ``missing``/``default`` field parameters with
``load_default``/``dump_default`` (:pr:`1742`).
Thanks :user:`sirosen` for the PR.

Deprecations:

- The use of ``missing``/``default`` field parameters is deprecated and will be
removed in marshmallow 4. ``load_default``/``dump_default`` should be used
instead.

*******************

Bug fixes:

- Don't expose ``Field``\s as ``Schema`` attributes. This reverts a change
introduced in 3.12.0 that causes issues when field names conflict with
``Schema`` attributes or methods. ``Fields``\s are still accessible on a
``Schema`` instance through the ``fields`` attribute. (:pr:`1843`)

*******************

Bug fixes:

- Fix bug that raised an ``AttributeError`` when instantiating a
``Schema`` with a field named ``parent`` (:issue:`1808`).
Thanks :user:`flying-sheep` for reporting and helping with the fix.

*******************

Features:

- Add ``validate.And`` (:issue:`1768`).
Thanks :user:`rugleb` for the suggestion.
- Add type annotations to ``marshmallow.decorators`` (:issue:`1788`, :pr:`1789`).
Thanks :user:`michaeldimchuk` for the PR.
- Let ``Field``\s be accessed by name as ``Schema`` attributes (:pr:`1631`).

Other changes:

- Improve types in ``marshmallow.validate`` (:pr:`1786`).
- Make ``marshmallow.validate.Validator`` an abstract base class (:pr:`1786`).
- Remove unnecessary list cast (:pr:`1785`).

*******************

Bug fixes:

- Fix treatment of dotted keys when ``unknown=INCLUDE`` (:issue:`1506`).
Thanks :user:`rbu` for reporting and thanks :user:`sirosen` for the fix (:pr:`1745`).

*******************

Features:

- Add ``fields.IPInterface``, ``fields.IPv4Interface``, and
``IPv6Interface`` (:issue:`1733`). Thanks :user:`madeinoz67`
for the suggestion and the PR.
- Raise ``AttributeError`` for missing methods when using ``fields.Method`` (:pr:`1675`).
Thanks :user:`lassandroan`.

Other changes:

- Remove unnecessary ``hasattr`` and ``getattr`` checks in ``Field`` (:pr:`1770`).
