### [`v2.12.4`](https://redirect.github.com/pydantic/pydantic/blob/HEAD/HISTORY.md#v2124-2025-11-05)

[Compare Source](https://redirect.github.com/pydantic/pydantic/compare/v2.12.3...v2.12.4)

[GitHub release](https://redirect.github.com/pydantic/pydantic/releases/tag/v2.12.4)

This is the fourth 2.12 patch release, fixing more regressions, and reverting a change in the `build()` method
of the [`AnyUrl` and Dsn types](https://docs.pydantic.dev/latest/api/networks/).

This patch release also fixes an issue with the serialization of IP address types, when `serialize_as_any` is used. The next patch release
will try to address the remaining issues with *serialize as any* behavior by introducing a new *polymorphic serialization* feature, that
should be used in most cases in place of *serialize as any*.

-   Fix issue with forward references in parent `TypedDict` classes by [@&#8203;Viicos](https://redirect.github.com/Viicos) in [#&#8203;12427](https://redirect.github.com/pydantic/pydantic/pull/12427).

    This issue is only relevant on Python 3.14 and greater.

-   Exclude fields with `exclude_if` from JSON Schema required fields by [@&#8203;Viicos](https://redirect.github.com/Viicos) in [#&#8203;12430](https://redirect.github.com/pydantic/pydantic/pull/12430)

-   Revert URL percent-encoding of credentials in the `build()` method
    of the [`AnyUrl` and Dsn types](https://docs.pydantic.dev/latest/api/networks/) by [@&#8203;davidhewitt](https://redirect.github.com/davidhewitt) in
    [pydantic-core#1833](https://redirect.github.com/pydantic/pydantic-core/pull/1833).

    This was initially considered as a bugfix, but caused regressions and as such was fully reverted. The next release will include
    an opt-in option to percent-encode components of the URL.

-   Add type inference for IP address types by [@&#8203;davidhewitt](https://redirect.github.com/davidhewitt) in [pydantic-core#1868](https://redirect.github.com/pydantic/pydantic-core/pull/1868).

    The 2.12 changes to the `serialize_as_any` behavior made it so that IP address types could not properly serialize to JSON.

-   Avoid getting default values from defaultdict by [@&#8203;davidhewitt](https://redirect.github.com/davidhewitt) in [pydantic-core#1853](https://redirect.github.com/pydantic/pydantic-core/pull/1853).

    This fixes a subtle regression in the validation behavior of the [`collections.defaultdict`](https://docs.python.org/3/library/collections.html#collections.defaultdict)
    type.

-   Fix issue with field serializers on nested typed dictionaries by [@&#8203;davidhewitt](https://redirect.github.com/davidhewitt) in [pydantic-core#1879](https://redirect.github.com/pydantic/pydantic-core/pull/1879).

-   Add more `pydantic-core` builds for the three-threaded version of Python 3.14 by [@&#8203;davidhewitt](https://redirect.github.com/davidhewitt) in [pydantic-core#1864](https://redirect.github.com/pydantic/pydantic-core/pull/1864).
