v0.120.0

Compare Source

There are no major nor breaking changes in this release. ☕️

The internal reference documentation now uses annotated_doc.Doc instead of typing_extensions.Doc, this adds a new (very small) dependency on annotated-doc, a package made just to provide that Doc documentation utility class.

I would expect typing_extensions.Doc to be deprecated and then removed at some point from typing_extensions, for that reason there's the new annotated-doc micro-package. If you are curious about this, you can read more in the repo for annotated-doc.

This new version 0.120.0 only contains that transition to the new home package for that utility class Doc.

Translations

• 🌐 Sync German docs. PR #​14188 by @​nilslindemann.

Internal

• ➕ Migrate internal reference documentation from typing_extensions.Doc to annotated_doc.Doc. PR #​14222 by @​tiangolo.
• 🛠️ Update German LLM prompt and test file. PR #​14189 by @​nilslindemann.

Internal

• 🔧 Add sponsor Requestly. PR #​14205 by @​tiangolo.
• 🔧 Configure reminder for waiting label in issue-manager. PR #​14156 by @​YuriiMotov.

v0.119.0

Compare Source

FastAPI now (temporarily) supports both Pydantic v2 models and pydantic.v1 models at the same time in the same app, to make it easier for any FastAPI apps still using Pydantic v1 to gradually but quickly migrate to Pydantic v2.

from fastapi import FastAPI
from pydantic import BaseModel as BaseModelV2
from pydantic.v1 import BaseModel

class Item(BaseModel):
    name: str
    description: str | None = None

class ItemV2(BaseModelV2):
    title: str
    summary: str | None = None

app = FastAPI()

@​app.post("/items/", response_model=ItemV2)
def create_item(item: Item):
    return {"title": item.name, "summary": item.description}

Adding this feature was a big effort with the main objective of making it easier for the few applications still stuck in Pydantic v1 to migrate to Pydantic v2.

And with this, support for Pydantic v1 is now deprecated and will be removed from FastAPI in a future version soon.

Note: have in mind that the Pydantic team already stopped supporting Pydantic v1 for recent versions of Python, starting with Python 3.14.

You can read in the docs more about how to Migrate from Pydantic v1 to Pydantic v2.

Features

• ✨ Add support for from pydantic.v1 import BaseModel, mixed Pydantic v1 and v2 models in the same app. PR #​14168 by @​tiangolo.

v0.118.3

Upgrades

• ⬆️ Add support for Python 3.14. PR #​14165 by @​svlandeg.
