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:

GitHub release
This is the fifth 2.12 patch release, addressing an issue with the
MISSINGsentinel and providing several documentation improvements.The next 2.13 minor release will be published in a couple weeks, and will include a new polymorphic serialization feature addressing
the remaining unexpected changes to the serialize as any behavior.
model_construct()on a model withMISSINGas a default value by @ornariece in #12522.v2.12.4Compare Source
GitHub release
This is the fourth 2.12 patch release, fixing more regressions, and reverting a change in the
build()methodof the
AnyUrland Dsn types.This patch release also fixes an issue with the serialization of IP address types, when
serialize_as_anyis used. The next patch releasewill 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
TypedDictclasses by @Viicos in #12427.This issue is only relevant on Python 3.14 and greater.
Exclude fields with
exclude_iffrom JSON Schema required fields by @Viicos in #12430Revert URL percent-encoding of credentials in the
build()methodof the
AnyUrland Dsn types by @davidhewitt inpydantic-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_anybehavior 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.defaultdicttype.
Fix issue with field serializers on nested typed dictionaries by @davidhewitt in pydantic-core#1879.

GitHub release
What's Changed
This is the third 2.12 patch release, fixing issues related to the
FieldInfoclass, and reverting a change to the supportedafter model validator function signatures.
Starting in 2.12.0, using class methods for after model validators raised an error, but the error wasn't raised concistently. We decided
to emit a deprecation warning instead.

FieldInfoclasses, that are reused asAnnotatedmetadata. However, note that this is stillnot a supported pattern. Instead, please refer to the added example in the documentation.
