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)

```
