[dependabot]

Bumps the python-runtime group with 3 updates in the / directory: fastapi, starlette and pydantic.

Updates fastapi from 0.142.2 to 0.162.0

Release notes

Sourced from fastapi's releases.

0.162.0

Omitted bool and bool | None form fields now use their declared defaults or produce missing-field errors, consistent with other fields and Pydantic behavior. FastAPI no longer infers False for 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 and validate_default follow the usual rules.

For HTML checkboxes, declare a boolean with a default of False. See Boolean Form Fields.

Breaking Changes

• 🐛 Restore default handling for omitted boolean form fields. PR #16605 by @​tiangolo.

0.161.1

Fixes

• 🐛 Fix OpenAPI schemas for standalone nullable form unions. PR #16598 by @​tiangolo.

0.161.0

Features

• ✨ Add support for combining unions of form models. PR #16596 by @​tiangolo.

0.160.0

Query, header, cookie, and form parameter models now apply their extra configuration 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. With extra="allow", those fields are included as model extras. With the default extra="ignore", they are ignored.

Breaking Changes

• 🐛 Apply each parameter model's extra configuration to sibling fields. PR #16594 by @​tiangolo.

Updates starlette from 1.7.0 to 1.10.0

Release notes

Sourced from starlette's releases.

Version 1.10.0

📝 Leaner URL-encoded form parsing

Starlette 1.10.0 parses URL-encoded forms with less memory and CPU, no longer drops the last field when a stream ends early, and lets you compare FormData that holds several uploads under one key.

uv pip install starlette==1.10.0

• Forms with many fields parse faster and use less memory (#3724). FormParser builds each field in the parser callbacks instead of queueing every event and replaying it. On CodSpeed, 1000 fields went from 42.8 ms to 34.9 ms and from 63.5 KB to 54.5 KB, and the max_fields limit case went from 6,880 B to 864 B.
• The last field is kept when the request stream ends without an empty chunk (#3599). The parser is now finalized once the stream is exhausted, so custom streams that never yield a final b"" no longer lose their last field.
• FormData with repeated uploads can be compared (#3619). Comparing two FormData objects with several UploadFile values under the same key used to raise TypeError.

⚠️ Behaviour changes

• Multidict equality keeps the order of values under a repeated key (#3619). Keys can still appear in any order, but QueryParams("a=1&a=2") and QueryParams("a=2&a=1") are no longer equal, matching what getlist() returns.
• starlette.formparsers.FormMessage is deprecated (#3724). The parser no longer uses it, and FormParser.messages is gone. Calling FormMessage(...) emits a StarletteDeprecationWarning.

🧭 Routing and URL generation

• Path parameter values that look like a placeholder are kept as they are (#3725). url_path_for("route", category="{id}", id="42") on /{category}/{id} now returns /{id}/42 instead of /42/42. Substitution also got faster, from 549 ns to 520 ns with two parameters and from 1,078 ns to 779 ns with five.
• Route matching does less work per request (#3665, #3722). Match members are compared by identity, cutting up to 4.9% of the instructions per dispatch in the routing benchmarks.
• WSGIMiddleware strips root_path only at a path segment boundary (#3718). A request to /application under a root_path of /app no longer becomes /lication.
• FloatConvertor reports NaN and infinity correctly (#3716). NaN was reported as a negative float.

🛡️ Middleware, responses and config

• Handled exceptions no longer keep requests alive (#3205). Starlette clears the traceback after an exception handler runs, so an exception instance reused across requests, such as a module-level HTTPException, no longer pins per-request objects in memory.
• Middlewares accept http.response.start without headers (#3721). BaseHTTPMiddleware, GZipMiddleware and SessionMiddleware default the omitted field to an empty list instead of raising KeyError.
• FileResponse ignores Range on methods other than GET and HEAD (#3679). A POST endpoint that returns a file now sends the full file, as RFC 9110 requires.
• Config strips one pair of matching outer quotes from env file values (#3720). KEY='say "hi"' now reads as say "hi" instead of say "hi.

Full changelog: 1.9.0...1.10.0

Version 1.9.0

This release streams TestClient response bodies, so client.stream() returns before the application finishes. It also escapes path delimiters when building URLs, matches host names case-insensitively, and keeps every existing Vary header.

Changed

• Stream TestClient response bodies, so client.stream() returns before the application finishes. Closing an unfinished streamed response now cancels the application #3491.

Fixed

• Percent-encode ?, #, \ and a leading // in the request path when building request.url, and \ and a leading // in url_path_for #3671.
• Use the byte length for Content-Length when the response body is a typed or multidimensional memoryview #3622.
• Include HEAD in the Allow header of HTTPEndpoint 405 responses when GET is defined #3585.
• Match host names case-insensitively in Host routing and TrustedHostMiddleware #3542.
• Preserve every existing Vary header in MutableHeaders.add_vary_header(), used by GZipMiddleware and SessionMiddleware #3675.

Changelog

Sourced from starlette's changelog.

1.10.0 (October 24, 2026)

Changed

• Compare multidicts such as FormData and QueryParams by key while keeping the order of values under a repeated key, so FormData with repeated uploads no longer raises TypeError. QueryParams("a=1&a=2") and QueryParams("a=2&a=1") are no longer equal #3619.
• Build URL-encoded form fields in the parser callbacks, lowering memory and CPU usage for forms with many fields #3724.
• Compare Match members by identity during routing #3665 and #3722.

Deprecated

• Deprecate starlette.formparsers.FormMessage, which is no longer used #3724.

Fixed

• Parse the last URL-encoded form field when the request stream ends without an empty chunk #3599.
• Keep path parameter values that look like another placeholder in url_path_for() #3725.
• Default omitted http.response.start headers in BaseHTTPMiddleware, GZipMiddleware and SessionMiddleware instead of raising KeyError #3721.
• Clear the traceback of handled exceptions, so reused exception instances no longer keep per-request objects alive #3205.
• Strip only one pair of matching outer quotes from Config env file values #3720.
• Strip root_path from PATH_INFO only at a path segment boundary in WSGIMiddleware #3718.
• Report NaN and infinity correctly in FloatConvertor.to_string() #3716.
• Ignore Range on requests other than GET and HEAD in FileResponse #3679.

1.9.0 (October 18, 2026)

Changed

• Stream TestClient response bodies, so client.stream() returns before the application finishes. Closing an unfinished streamed response now cancels the application #3491.

Fixed

• Percent-encode ?, #, \ and a leading // in the request path when building request.url, and \ and a leading // in url_path_for #3671.
• Use the byte length for Content-Length when the response body is a typed or multidimensional memoryview #3622.
• Include HEAD in the Allow header of HTTPEndpoint 405 responses when GET is defined #3585.
• Match host names case-insensitively in Host routing and TrustedHostMiddleware #3542.
• Preserve every existing Vary header in MutableHeaders.add_vary_header(), used by GZipMiddleware and SessionMiddleware #3675.

1.8.0 (October 13, 2026)

This release drops Python 3.10 support and adds HTTP 103 Early Hints.

Added

• Add Request.send_early_hints() for HTTP 103 Early Hints through the ASGI http.response.early_hint extension #3435.

Changed

• Require Python 3.11 or later, dropping support for Python 3.10 #3592.
• Exclude native gRPC media types (application/grpc and application/grpc+...) from GZipMiddleware compression by default #3565.
• Send http.response.start immediately in GZipMiddleware for responses with an existing Content-Encoding, status 206, or an excluded content type, instead of waiting for the first body chunk #3631.

Updates pydantic from 2.13.5 to 2.14.2

Release notes

Sourced from pydantic's releases.

v2.14.2 2026-10-29

v2.14.2 (2026-10-29)

This release addresses 2 security issues, GHSA-qpmf-fgh3-ff25 and GHSA-3r8g-cqwr-jr29.

Packaging

• Bump PyO3 to 0.30.1, jiter to 0.18.0, use PyFrozenDict by @​Viicos in #14003
• Bump speedate to v0.18.0 by @​Viicos in #14007
• Publish pydantic-core wheels for PyPy 8.0 (pp80 ABI) by @​Viicos in #14083

Performance

• Avoid Python tuple allocation during model fields validation by @​Viicos in #13955
• Lazily call repr of values during nested union serialization by @​Viicos in #14082
• Skip decorator field checks when no field decorators exist by @​alexmojaki in #14111
• Avoid heap allocation for small JSON model field buffers by @​alexmojaki in #14113

Fixes

• Make JSON validation by iteration consistent with Python approach by @​davidhewitt in #13275.

  JSON validation now handles field lookup and extra data the same way as Python validation. In particular, keys that only match an unused alias or field name are now treated as extra data, instead of being silently dropped:

  from pydantic import BaseModel, ConfigDict
  from pydantic.alias_generators import to_camel
  class Page(BaseModel):
  model_config = ConfigDict(extra='forbid', alias_generator=to_camel)
  page_size: int = 10
  
  Page.model_validate_json('{"page_size": 50}')
  Before: Page(page_size=10)
  After: ValidationError (extra_forbidden)

  See the pull request for the full list of behavior changes. This change addresses GHSA-qpmf-fgh3-ff25.

• Ignore extra data matching a field name in TypedDict and dataclasses with extra=allow by @​Viicos in #14090. Addresses GHSA-3r8g-cqwr-jr29.

• Fix unpickling of generic classes defined in separate module by @​Viicos in #13994

• Support explicit by_alias overriding validate_by_alias in validation JSON schemas by @​Viicos in #13997

• Fix mypy plugin crash on deferred empty model by @​ilevkivskyi in #14027

• Fix infinite recursion when validating an invalid default with PydanticUseDefault by @​Viicos in #14028

• Implement recursion guard for validate_strings() by @​Viicos in #14029
