Bumps fastapi from 0.141.1 to 0.150.0.

Release notes

Sourced from fastapi's releases.

0.150.0

When no file is selected, browsers submit a file part with an empty filename and empty content. FastAPI now treats this as missing: required file fields return a validation error, and fields with defaults or default factories use them. Unselected inputs are ignored in lists of files. Named zero-byte files are still accepted.

Breaking Changes

• 🐛 Treat unselected browser file inputs as missing. PR #16534 by @​tiangolo.

0.149.0

Browsers submit empty text inputs as empty strings (""). FastAPI now treats empty scalar form values as missing in form models, matching individual Form parameters. Required fields return a validation error. Fields with defaults or default factories use them and remain unset in model_dump(exclude_unset=True).

Empty strings inside lists are preserved. Omitted boolean form fields still become False. JSON requests and direct Pydantic validation are unchanged.

Breaking Changes

• 🐛 Treat empty scalar values as missing in form models. PR #16529 by @​tiangolo.

0.148.0

Defaults for omitted Query, Header, Cookie, and Form parameters and model fields are no longer treated as user input. Defaults are not validated unless validate_default=True is enabled. If you rely on validators running for omitted values, enable default validation with Field(validate_default=True) for model fields or, for example, Query(validate_default=True) for individual parameters. Body(validate_default=True) is now honored too.

For parameter models, applying a default no longer marks a field as explicitly set, so model_dump(exclude_unset=True) excludes it. Default factories run once, and validation errors no longer include injected defaults in input.

Omitted boolean form fields still become False and count as explicitly set.

Breaking Changes

• 🐛 Fix default handling for request parameters and models. PR #16527 by @​tiangolo.

0.147.0

Omitted bool and bool | None form fields are now interpreted as False, matching unchecked HTML checkboxes. This applies to individual Form parameters and form models, including required fields and fields with defaults of True or None. The inferred value is considered explicitly set, including in model_dump(exclude_unset=True).

JSON requests and direct Pydantic validation are unchanged. See Boolean Form Fields.

Breaking Changes

• 🐛 Treat omitted boolean form fields as False. PR #16523 by @​tiangolo.

Internal

• ✅ Add tests for parameter defaults, nullability, and browser form behavior. PR #14829 by @​YuriiMotov.

0.146.0

The root_path parameter in FastAPI() is deprecated. Configure the server with fastapi run --root-path /api/v1 instead.

Breaking Changes

• 🗑️ Deprecate the root_path parameter in FastAPI. PR #16520 by @​tiangolo.
