Updates fastapi from 0.141.1 to 0.149.0

Release notes

Sourced from fastapi's releases.

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.

Updates pydantic-settings from 2.15.0 to 2.16.0

Release notes

Sourced from pydantic-settings's releases.

v2.16.0

Highlights

Breaking changes and behavior changes

• Python 3.10 is no longer supported (#1003). pydantic-settings now requires Python 3.11+, since 3.10 reaches end of life this month. The tomli fallback is gone in favor of stdlib tomllib; the toml extra is kept as an empty extra so pip install pydantic-settings[toml] keeps working.
• python-dotenv>=1.2.2 is now required (#971) to pick up the fix for CVE-2026-28684.
• Aliases are ignored in every source when validate_by_alias=False (#1033). Env vars, secrets, CLI flags and defaults now use only field names, matching pydantic. An env var named after the alias is now ignored instead of raising extra_forbidden, and the CLI exposes --apple rather than --pomo.
• validation_alias takes precedence over alias (#1038). When the two differ, values from JSON/YAML/TOML files and the CLI were silently ignored; they now load. CLI help lists the validation_alias flag first, and CliApp.serialize emits it.
• CLI case-insensitivity only lowercases registered options (#1036). With case_sensitive=False, args after -- and those captured by CliUnknownArgs keep their case (-Xmx4G no longer becomes -xmx4g). Unrecognized options are now reported as typed (--NOPE instead of --nope).
• JSON and YAML config files are read as UTF-8 by default (#955) instead of the locale encoding, completing the secrets-file fix from 2.15.0. json_file_encoding/yaml_file_encoding still override it.
• Discriminated union defaults are partially updated again (#997). This reverts the 2.15.0 regression with nested_model_default_partial_update=True: the default is only dropped when the incoming value selects a different union member.

New features

• Python 3.15 and pydantic 2.14 support (#1026, #1029, #1022). pydantic 2.14 broke CliApp.run and validate_by_alias=False handling; both are fixed.
• Cached settings instances via Settings.settings_cached() and Settings.settings_clear_cache() (#952). These give you a process-local singleton per settings class without hand-rolling lru_cache wrappers. Calling the class directly still builds a fresh instance.
• AWS Systems Manager Parameter Store source — AWSSystemsManagerSettingsSource (#941). It recursively reads every parameter under an ssm_path, with / mapping onto nested models. Install it with the new aws-systems-manager extra.
• env_file_depth (#940) lets a relative env_file be found in parent directories, mirroring pyproject_toml_depth. This is useful when scripts run from a subdirectory of a monorepo. It defaults to 0, which keeps the current behavior.
• CliVariadicArg for named variadic options (#949, #958). It accepts --param a b c in addition to repeated --param a --param b. Required fields need at least one value.

Bug fixes

CLI

• CliApp.serialize output now round-trips through CliApp.run for enums, tuples, dates and Decimals (#988), explicit None values (#981), empty containers (#1008), CliVariadicArg values (#976) and populated CliUnknownArgs fields, which previously raised IndexError (#992).
• Empty JSON arrays (--items []) now give an empty list instead of [''] (#994).
• Tuples, frozenset, MutableSequence and other collection subtypes are now treated as repeatable/variadic options (#972), and so are named collection type aliases such as TypeAliasType('Addrs', list[IPvAnyAddress]) (#1032).
• cli_exit_on_error=False is now honored in CliSubCommand parsers, which raise SettingsError instead of exiting (#977).
• CliSubCommand aliases keep their case with case_sensitive=False (#989).
• Each CliUnknownArgs field now receives only its own subcommand's leftover args (#1004).
• CliApp.format_help no longer crashes when cli_prefix is set in model_config (#945).

Type aliases and parsing

• Named union type aliases (TypeAliasType('V', list[int] | str)) now decode like their inline equivalents in env and dotenv sources, including under Optional, Annotated and custom validation aliases (#1006, #1030, #1041).
• Resolving a named Annotated type alias no longer mutates shared FieldInfo metadata, which made validators run twice on subclasses or after model_rebuild() (#979).
• A bare single-segment AliasPath('SOME_KEY') no longer tries to JSON-decode plain string values (#980).
• collections.abc.Set/MutableSet/typing.AbstractSet fields now JSON-decode env values (#973).
• A bare typing.Dict field with env_nested_delimiter no longer raises IndexError, which was a regression in 2.13.0 (#1009).
• Case-insensitive matching now works for nested pydantic dataclasses (#1010).

Dotenv, secrets and config files

• With extra='allow', a non-lowercase env_prefix is now stripped from dotenv extras (#959, #968).
• secrets_case_sensitive=True is now honored on Windows (#1001).
• An empty JSON config file is treated as an empty mapping instead of crashing (#947), matching YAML and TOML.
• TOML table headers: ~ paths are now expanded when checking that the file exists (#1034), and an explicit toml_table_header=() now overrides the model config to read the file root (#1027).

Cloud sources

• Azure Key Vault and GCP Secret Manager now honor env_parse_none_str (#1019, #1040).
• Azure Key Vault: dash_to_underscore=True now works for nested model fields (#1025).
• NestedSecretsSettingsSource now validates its specific constructor arguments (#975).

Mypy Release Notes

Next Release

Mypy 2.4

We've just uploaded mypy 2.4.0 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:

python3 -m pip install -U mypy

You can read the full documentation for this release on Read the Docs.

Python 3.15 Support

Mypy 2.4 supports running on Python 3.15 and type checking most Python 3.15 features. This includes the new builtin sentinel type for sentinel values (PEP 661), which mypy now supports (see below for details). Lazy imports (PEP 810) and unpacking in comprehensions (PEP 798) are also supported. Closed TypedDicts (PEP 728) have been supported since mypy 2.2, but the extra_items TypedDict argument, also introduced in PEP 728, is still unsupported. Support for extra_items will be added in a future mypy release.

Native Parser Enabled by Default

Mypy now uses the new native parser by default. It's based on the Ruff parser, and it's significantly faster than the legacy parser, which uses the stdlib ast module. The native parser also has other benefits:

• You can target newer Python versions and use recent Python syntax even when running mypy on an older Python version. For example, you can use --python-version 3.15 when running mypy on Python 3.14.
• Stub files can use syntax that is newer than the target Python version. For example, stubs can use the PEP 695 generic class syntax (class Box[T]: ...) when running on or targeting Python 3.10.
• Parallel type checking requires the native parser.

The legacy parser is still available through --no-native-parser, or native_parser = False in the config file (native_parser = false under [tool.mypy] in pyproject.toml). We are planning to remove the legacy parser in early 2027. If you run into a problem with the native parser, please report it on the issue tracker.

Unlike the legacy parser, the native parser doesn't support type comments for variables defined by for and with statements. These type comments are silently ignored, and the types of the variables are

0.17.0

Released on 2026-10-09.

The executables in our macOS and Windows release archives and ruff wheels are now code-signed. macOS executables are signed with an Apple Developer ID certificate and notarized by Apple. Windows executables have timestamped Authenticode signatures from Azure Artifact Signing. This enables verification of the release publisher and binary integrity, supports publisher-based allowlisting, and should reduce security warnings and antivirus false positives.

Breaking changes

• Update the default and latest Python versions for 3.15 (#28792)

  Ruff now defaults to Python 3.11 instead of 3.10 when no Python version is configured through target-version or requires-python. When checking for syntax errors without a configured Python version, Ruff now defaults to Python 3.15
