fastapi/fastapi (fastapi)
v0.162.0Compare Source
Omitted
boolandbool | Noneform fields now use their declared defaults or produce missing-field errors, consistent with other fields and Pydantic behavior. FastAPI no longer infersFalsefor omitted booleans. This applies to individual form parameters, form models, and unions of form models.Omitted boolean model fields are excluded from
model_dump(exclude_unset=True), and their defaults no longer count as submitted fields during union selection. Default factories andvalidate_defaultfollow the usual rules.For HTML checkboxes, declare a boolean with a default of
False. See Boolean Form Fields.Breaking Changes

Query, header, cookie, and form parameter models now apply their
extraconfiguration to all submitted fields in the same parameter location, consistent with Pydantic behavior. This includes fields declared in other models, individual parameters, or dependencies, which were previously excluded.With
extra="forbid", fields outside the model are rejected even if another parameter declares them. Withextra="allow", those fields are included as model extras. With the defaultextra="ignore", they are ignored.Breaking Changes

The deprecated
**extrakeyword arguments have been removed fromPath,Query,Header,Cookie,Body,Form, andFile. Unknown keyword arguments now raiseTypeError. For additional JSON Schema properties, replace, for example,Query(custom="value")withQuery(json_schema_extra={"custom": "value"}).Breaking Changes

v0.153.0Compare Source
Unions of form models now apply the same browser form handling as individual models. Empty scalar fields use defaults or produce missing-field errors, empty list items are preserved, omitted boolean fields become
False, and unselected files are treated as missing. JSON request bodies are unchanged.Fixes
v0.152.0Compare Source
Validation errors for header parameter models now report the HTTP header name, such as
int-val, instead of the Python field name,int_val. Explicit aliases,Header(convert_underscores=False), and Pydantic models withloc_by_alias=Falsekeep their existing behavior.Fixes
v0.151.0Compare Source
JSON request bodies now distinguish an explicit
nullfrom an omitted value. For individualBodyparameters,nullis validated asNone: nullable types accept it, and non-nullable types reject it even when a default is defined. Defaults and default factories apply only when the value is omitted. This applies both to parameters inside JSON objects and to parameters representing the entire body. Clients that usednullto request a default should omit the value instead.When a JSON object is expected because of
Body(embed=True)or multiple body parameters, sendingnullas the entire body now returns a validation error.Breaking Changes
v0.150.0Compare Source
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
v0.149.0Compare Source
Browsers submit empty text inputs as empty strings (
""). FastAPI now treats empty scalar form values as missing in form models, matching individualFormparameters. Required fields return a validation error. Fields with defaults or default factories use them and remain unset inmodel_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
v0.148.0Compare Source
Defaults for omitted
Query,Header,Cookie, andFormparameters and model fields are no longer treated as user input. Defaults are not validated unlessvalidate_default=Trueis enabled. If you rely on validators running for omitted values, enable default validation withField(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 ininput.Omitted boolean form fields still become
Falseand count as explicitly set.Breaking Changes
v0.147.0Compare Source
Omitted
boolandbool | Noneform fields are now interpreted asFalse, matching unchecked HTML checkboxes. This applies to individualFormparameters and form models, including required fields and fields with defaults ofTrueorNone. The inferred value is considered explicitly set, including inmodel_dump(exclude_unset=True).JSON requests and direct Pydantic validation are unchanged. See Boolean Form Fields.

Automatic OpenTelemetry exporter setup is now opt-in. If you rely on FastAPI to configure exporters from
OTEL_*environment variables, setFASTAPI_OTEL_AUTO_CONFIGURE=trueor useFastAPI(telemetry={"auto_configure": True})to retain the previous behavior.Applications that configure their own providers and exporters require no changes. FastAPI Cloud enables automatic setup for you.
