0.143.1

Fixes

0.143.0

Automatic OpenTelemetry exporter setup is now opt-in. If you rely on FastAPI to configure exporters from OTEL_* environment variables, set FASTAPI_OTEL_AUTO_CONFIGURE=true or use FastAPI(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.

Updates uvicorn from 0.52.4 to 0.54.0

Release notes

Sourced from uvicorn's releases.

Version 0.54.0

📨 Send metadata after the response body

uvicorn 0.54.0 adds response trailers and 103 Early Hints to its experimental HTTP/2 implementation through zttp.

uv add uvicorn==0.54.0 "zttp>=0.0.34"
  • Send HTTP/2 response trailers (#3146). The ASGI http.response.trailers extension lets applications send metadata, such as checksums, after the response body. Clients must send TE: trailers to receive them. Multiple trailer messages are combined before completing the response.
  • HTTP/2 remains experimental and opt-in. Enable it with --http zttp --http2. Upgrade-based h2c and WebSockets over HTTP/2 remain unsupported.

💡 Hint at resources before the final response

  • Send 103 Early Hints over HTTP/2 (#3137). Applications can use the ASGI http.response.early_hint extension to send resource hints before the final response. Each supplied link becomes a separate Link header.

Full changelog: 0.53.0...0.54.0

Version 0.53.0

🌐 Opt-in HTTP/2 support

uvicorn 0.53.0 adds experimental HTTP/2 through zttp, alongside a new zuvloop integration and connection-handling improvements.

uv add uvicorn==0.53.0
  • Serve HTTP/1.1 and HTTP/2 with zttp (#2982, #3101). Install zttp, then enable HTTP/2 with --http zttp --http2. Uvicorn negotiates HTTP/2 over TLS with ALPN and supports cleartext prior knowledge.
  • HTTP/2 remains experimental. Upgrade-based h2c and WebSockets over HTTP/2 are not supported.

⚙️ More event loop choice

  • Run Uvicorn with zuvloop (#3104). Install zuvloop separately and select it explicitly with --loop zuvloop on CPython 3.14 or newer.

🛡️ More reliable connections and proxies

  • Honor Connection: close token lists (#3103). Uvicorn now parses comma-separated tokens case-insensitively across HTTP implementations.
  • Trust IPv6 loopback proxies by default (#3119). The default FORWARDED_ALLOW_IPS value now includes ::1.
  • Keep upgraded WebSockets alive (#3107). Uvicorn cancels the HTTP keep-alive timer when the connection becomes a WebSocket.

Full changelog: 0.52.4...0.53.0

Changelog

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).

Updates sse-starlette from 3.4.8 to 3.5.0

Release notes

Sourced from sse-starlette's releases.

v3.5.0

Fixed

  • A stopped uvicorn server no longer cancels SSE streams of later servers in the same process (#211, regression since 3.1.1). Typical trigger: test suites starting a real server per test.

Behaviour change

  • AppStatus.should_exit is no longer set when sse-starlette detects uvicorn's own Server.should_exit (fallback path, e.g. uvicorn "module:app"). Streams still close on shutdown. If you read AppStatus.should_exit to detect shutdown, use shutdown_event instead.
  • A real SIGTERM/SIGINT still sets AppStatus.should_exit process-wide; see README "Testing" if your tests send real signals to an in-process server.

Upgrade note

  • If you called AppStatus.disable_automatic_graceful_drain() only to work around #211, remove it to get automatic stream draining back.
