    # Typer

    ## 0.20.0

    ### Features

    *  Enable command suggestions on typo by default.

    ### Upgrades

    *  Add (official) support for Python 3.14.

    ### Internal

    Assorted small enhancements.

    ----

    # FastAPI

    ## 0.120.1

    ### Upgrades

    *  Bump Starlette to <`0.50.0`.

    ### Internal

    *  Add `license` and `license-files` to `pyproject.toml`, remove `License` from `classifiers`.

    ## 0.120.0

    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`](https://github.com/fastapi/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`](https://github.com/fastapi/annotated-doc).

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

    ### Translations, Internal

    Assorted improvements.

    ## 0.119.1

    ### Fixes

    *  Fix internal Pydantic v1 compatibility (warnings) for Python 3.14 and Pydantic 2.12.1.

    ### Docs, Internal

    Assorted improvements.

    ## 0.119.0

    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**.

    ### Features

    *  Add support for `from pydantic.v1 import BaseModel`, mixed Pydantic v1 and v2 models in the same     app.

    ## 0.118.3

    ### Upgrades

    - Add (official) support for Python 3.14.

    ## 0.118.2

    ### Fixes

    *  Fix tagged discriminated union not recognized as body field.

    ## 0.118.1

    ### Upgrades

    *  Ensure compatibility with Pydantic 2.12.0.

    ### Docs, Translations, Internal

    Assorted bugfixes and enhancements.

    ## 0.118.0

    ### Fixes

    *  Fix support for `StreamingResponse`s with dependencies with `yield` or `UploadFile`s, close after     the response is done.

    Before FastAPI 0.118.0, if you used a dependency with `yield`, it would run the exit code after the *path     operation function* returned but right before sending the response.

    This change also meant that if you returned a `StreamingResponse`, the exit code of the dependency with     `yield` would have been already run.

    For example, if you had a database session in a dependency with `yield`, the `StreamingResponse` would not     be able to use that session while streaming data because the session would have already been closed in the     exit code after `yield`.

    This behavior was reverted in 0.118.0, to make the exit code after `yield` be executed after the response     is sent.

    You can read more about it in the docs for [Advanced Dependencies - Dependencies with `yield`,     `HTTPException`, `except` and Background Tasks](https://fastapi.tiangolo.com/advanced/advanced-     dependencies#dependencies-with-yield-httpexception-except-and-background-tasks). Including what you could     do if you wanted to close a database session earlier, before returning the response to the client.
