GitHub release

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.

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 @​Viicos in #​12427.

  This issue is only relevant on Python 3.14 and greater.

• Exclude fields with exclude_if from JSON Schema required fields by @​Viicos in #​12430

• Revert URL percent-encoding of credentials in the build() method
  of the AnyUrl and Dsn types by @​davidhewitt in
  pydantic-core#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 @​davidhewitt in pydantic-core#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 @​davidhewitt in pydantic-core#1853.

  This fixes a subtle regression in the validation behavior of the collections.defaultdict
  type.

• Fix issue with field serializers on nested typed dictionaries by @​davidhewitt in pydantic-core#1879.

• Add more pydantic-core builds for the three-threaded version of Python 3.14 by @​davidhewitt in pydantic-core#1864.
