Updates multidict from 7.1.0 to 7.2.1

Release notes

Sourced from multidict's releases.

7.2.1

Bug fixes

• Fixed a regression in 7.2.0 where a subclass of MultiDictProxy or CIMultiDictProxy that converted its argument in its own __init__() raised TypeError before that __init__() ran; such a subclass got an empty multidict until its __init__() set the proxied one -- by @​asvetlov.

  Related issues and pull requests on GitHub: #1824, #1825.

---

7.2.0 drops Python 3.10, fixes a crash in a proxy built without __init__() and a MemoryError from a huge __length_hint__(), and is otherwise a performance release for the C extension: lookups, adds, updates and deletes each needed a few percent fewer instructions.

Bug fixes

• Stopped a huge __length_hint__() from raising MemoryError in extend(), update() and merge(); the C extension capped the room it reserved for the hint at the largest table the constructor allocates up front -- by @​asvetlov.

  Related issues and pull requests on GitHub: #1767.

• Fixed a segmentation fault when using a MultiDictProxy or CIMultiDictProxy built by __new__() without __init__(); __new__() started requiring the proxied multidict, the same argument as the constructor -- by @​asvetlov.

  Related issues and pull requests on GitHub: #1782.

Features

• Sped up reading a multidict in the C extension. md[key], get() and getone() became up to 7% faster by returning the lookup's result by value instead

Updates pydantic from 2.14.1 to 2.14.2

Release notes

Sourced from pydantic's releases.

v2.14.2 2026-10-29

v2.14.2 (2026-10-29)

This release addresses 2 security issues, GHSA-qpmf-fgh3-ff25 and GHSA-3r8g-cqwr-jr29.

Packaging

• Bump PyO3 to 0.30.1, jiter to 0.18.0, use PyFrozenDict by @​Viicos in #14003
• Bump speedate to v0.18.0 by @​Viicos in #14007
• Publish pydantic-core wheels for PyPy 8.0 (pp80 ABI) by @​Viicos in #14083

Performance

• Avoid Python tuple allocation during model fields validation by @​Viicos in #13955
• Lazily call repr of values during nested union serialization by @​Viicos in #14082
• Skip decorator field checks when no field decorators exist by @​alexmojaki in #14111
• Avoid heap allocation for small JSON model field buffers by @​alexmojaki in #14113

Fixes

• Make JSON validation by iteration consistent with Python approach by @​davidhewitt in #13275.

  JSON validation now handles field lookup and extra data the same way as Python validation. In particular, keys that only match an unused alias or field name are now treated as extra data, instead of being silently dropped:

  from pydantic import BaseModel, ConfigDict
  from pydantic.alias_generators import to_camel
  class Page(BaseModel):
  model_config = ConfigDict(extra='forbid', alias_generator=to_camel)
  page_size: int = 10
  
  Page.model_validate_json('{"page_size": 50}')
  Before: Page(page_size=10)
  After: ValidationError (extra_forbidden)

  See the pull request for the full list of behavior changes. This change addresses GHSA-qpmf-fgh3-ff25.

• Ignore extra data matching a field name in TypedDict and dataclasses with extra=allow by @​Viicos in #14090. Addresses GHSA-3r8g-cqwr-jr29.

• Fix unpickling of generic classes defined in separate module by @​Viicos in #13994

• Support explicit by_alias overriding validate_by_alias in validation JSON schemas by @​Viicos in #13997

• Fix mypy plugin crash on deferred empty model by @​ilevkivskyi in #14027

• Fix infinite recursion when validating an invalid default with PydanticUseDefault by @​Viicos in #14028

• Implement recursion guard for validate_strings() by @​Viicos in #14029
