v2.12.3

Compare Source

GitHub release

What's Changed

This is the third 2.13 patch release, fixing issues related to the FieldInfo class, and reverting a change to the supported
after model validator function signatures.

• Raise a warning when an invalid after model validator function signature is raised by @​Viicos in #​12414.
  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.
• Add FieldInfo.asdict() method, improve documentation around FieldInfo by @​Viicos in #​12411.
  This also add back support for mutations on FieldInfo classes, that are reused as Annotated metadata. However, note that this is still
  not a supported pattern. Instead, please refer to the added example in the documentation.

The blog post section on changes was also updated to document the changes related to serialize_as_any.
