Update Information:

Pydantic 2.12.4 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. 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. https://github.com/pydantic/pydantic/releases/tag/v2.12.4 uv / python-uv-build 0.9.7 https://github.com/astral-sh/uv/releases/tag/0.9.7 0.9.6 This release contains an upgrade to Astral's fork of async_zip, which addresses potential sources of ZIP parsing differentials between uv and other Python packaging tooling.
