Marshmallow

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

Bug fixes:

- Fix publishing type hints per `PEP-561 <https://www.python.org/dev/peps/pep-0561/>`_
(:pr:`1905`). Thanks :user:`bwindsor` for the catch and patch.

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

Bug fixes:

- Fix ``fields.TimeDelta`` serialization precision (:issue:`1865`).
Thanks :user:`yarsanich` for reporting.

Other changes:

- Fix type-hints for ``data`` arg in ``Schema.validate`` to accept
list of dictionaries (:issue:`1790`, :pr:`1868`).
Thanks :user:`yourun-proger` for PR.
- Improve warning when passing metadata as keyword arguments (:pr:`1882`).
Thanks :user:`traherom` for the PR.
- Don't build universal wheels. We don't support Python 2 anymore.
(:issue:`1860`) Thanks :user:`YKdvd` for reporting.
- Make the build reproducible (:pr:`1862`).
- Drop support for Python 3.5 (:pr:`1863`).
- Test against Python 3.10 (:pr:`1888`).

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

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`).
