[dependabot]

Bumps marshmallow from 3.26.1 to 4.0.0.

Changelog

Sourced from marshmallow's changelog.

4.0.0 (2025-04-16)

---

See :ref:upgrading_4_0 for a guide on updating your code.

Features:

• Typing: Add types to all Field <marshmallow.fields.Field> constructor kwargs (:issue:2285). Thanks :user:navignaw for the suggestion.
• DateTime <marshmallow.fields.DateTime>, Date <marshmallow.fields.Date>, Time <marshmallow.fields.Time>, TimeDelta <marshmallow.fields.TimeDelta>, and Enum <marshmallow.fields.Enum> accept their internal value types as valid input (:issue:1415). Thanks :user:bitdancer for the suggestion.
• @validates <marshmallow.validates> accepts multiple field names (:issue:1960). Backwards-incompatible: Decorated methods now receive data_key as a keyword argument. Thanks :user:dpriskorn for the suggestion and :user:dharani7998 for the PR.

Other changes:

• Typing: Field <marshmallow.fields.Field> is now a generic type with a type argument for the internal value type.

• marshmallow.fields.UUID no longer subclasses marshmallow.fields.String.

• marshmallow.Schema.load no longer silently fails to call schema validators when a generator is passed (:issue:1898). The typing of data is also updated to be more accurate. Thanks :user:ziplokk1 for reporting.

• Backwards-incompatible: Use datetime.date.fromisoformat, datetime.time.fromisoformat, and datetime.datetime.fromisoformat from the standard library to deserialize dates, times and datetimes (:pr:2078). As a consequence of this change:

  • Time with time offsets are now supported.
  • YYYY-MM-DD is now accepted as a datetime and deserialized as naive 00:00 AM.
  • from_iso_date, from_iso_time and from_iso_datetime are removed from marshmallow.utils.

• Remove isoformat, to_iso_time and to_iso_datetime from marshmallow.utils (:pr:2766).

• Remove from_rfc, and rfcformat from marshmallow.utils (:pr:2767).

• Remove is_keyed_tuple from marshmallow.utils (:pr:2768).

• Remove get_fixed_timezone from marshmallow.utils (:pr:2773).

• Backwards-incompatible: marshmallow.fields.Boolean no longer serializes non-boolean values (:pr:2725).

• Backwards-incompatible: Rename schema parameter to parent in marshmallow.fields.Field._bind_to_schema (:issue:1360).

• Backwards-incompatible: Rename pass_many parameter to pass_collection in pre/post processing methods (:issue:1369).

• Backwards-incompatible: marshmallow.fields.TimeDelta no longer truncates float values when deserializing (:pr:2654). This allows microseconds to be preserved, e.g.

.. code-block:: python

from marshmallow import fields
field = fields.TimeDelta()
Before
field.deserialize(12.9)
datetime.timedelta(seconds=12)
datetime.timedelta(seconds=12)

... (truncated)

@dependabot rebase

[ccostino]

We're going to have to tackle this ourselves and there's no sense in keeping this PR open. The work is in #1678!

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
