Updates httpx2 from 2.12.0 to 2.13.1

Release notes

Sourced from httpx2's releases.

v2.13.1

Highlights

📤 Accurate file upload lengths

Passing a file as content= now calculates Content-Length from its remaining bytes, respecting the current file position (#1214).

🔐 Reliable proxy TLS and HTTP/2 negotiation

TLS hostname overrides now apply inside HTTP proxy tunnels without affecting the proxy's own TLS connection (#1223). HTTP/2 is advertised first when enabled, and HTTP/1.1 is omitted when disabled (#1155).

🧹 Clean WebSocket shutdown

The sync WebSocket keepalive thread now exits cleanly when a ping races with connection shutdown (#1228).

httpx2

Fixed

  • Calculate Content-Length from the remaining bytes when a file is passed as content=, respecting its current position (#1214).
  • Stop the sync WebSocket keepalive thread cleanly when a ping races with connection shutdown (#1228).

httpcore2

Fixed

  • Honor the sni_hostname extension for TLS inside HTTP proxy tunnels without applying it to the proxy's TLS connection (#1223).
  • Prefer HTTP/2 during TLS protocol negotiation when enabled, and stop advertising HTTP/1.1 when it is disabled (#1155).

Full Changelog: pydantic/httpx2@v2.13.0...v2.13.1

v2.13.0

Highlights

🔐 Reliable TLS verification controls

The CLI --no-verify flag now disables TLS certificate verification as intended, and --verify provides an explicit counterpart (pydantic/httpx2#1140, pydantic/httpx2#1186).

🧹 Safer async stream cleanup

Stopping a streamed response early no longer risks a nested async generator finalization error (pydantic/httpx2#1204).

Changed

  • Require brotlicffi 1.2.0.2 or later for the brotli extra on non-CPython implementations in pydantic/httpx2#1179

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

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 0.52.3 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

Version 0.52.4

Fixed

  • Remove duplicate Date headers from accepted WebSocket handshakes with websockets-sansio (#3078)

0.54.0 (September 24, 2026)

HTTP/2 support remains experimental. Install zttp>=0.0.34 and enable it with --http zttp --http2.

Added

  • Add HTTP/2 response trailers through the ASGI http.response.trailers extension. Clients must send TE: trailers to receive them (#3146)
  • Add HTTP/2 103 Early Hints through the ASGI http.response.early_hint extension (#3137)

0.53.0 (September 14, 2026)

Updates protobuf from 7.35.1 to 7.36.2

Updates idna from 3.18 to 3.20

Release notes

Sourced from idna's releases.

v3.20

  • Update to Unicode 18.0.0.
  • Better enforcement of the domain length limit in the incremental codec.
  • Add support for Python 3.15.

v3.19

  • Restore the std3_rules option, which had no effect since changes to UTS #46 processing in Unicode 16. Note that uts46_remap() defaults to enabling STD3 rules, so direct callers will see input containing non-LDH ASCII characters rejected again.
  • Performance improvements to UTS #46 mapping, particularly for ASCII-only domains.
  • Test on free-threaded CPython with the GIL disabled and document thread safety.
  • Expose the Unicode version of the generated tables as idna.unicode_version, and show it in idna --version.
  • Add code, text, codepoint and position attributes to IDNAError so that the failed rule and the offending character can be identified without parsing the exception message.
  • The deprecated transitional argument to encode() and uts46_remap() is now completely ignored, and gives a deprecation warning for the latter.
  • Reject A-labels that are not the canonical Punycode encoding of their U-label.
  • Fix CONTEXTJ violations raising IDNAError instead of InvalidCodepointContext.
  • Consistently raise IDNAError for empty labels and non-ASCII bytes passed to label helper functions and the incremental codec.
  • Add property-based tests, extended fuzzing targets, coverage measurement, and CI checks that the data tables match the generator output.
  • Various code quality and tooling improvements.

Updates python-dotenv from 1.2.2 to 1.2.4

Release notes

Sourced from python-dotenv's releases.

v1.2.4

Fixed

  • dotenv get no longer exits with code 1 for empty string values (KEY=) by [@​ShamikOfficial] in #700
  • An unquoted empty value followed by an inline comment (e.g. KEY= # comment) is now parsed as an empty string instead of the comment text by [@​Noethix55555] in #663
  • dotenv run --no-override now expands variable references with the same precedence as load_dotenv(override=False), so a value like ${BASE}/suffix uses the existing BASE from the environment instead of the one from the .env file by [@​ROTl24] in #698

v1.2.3

Fixed

  • Strip a leading UTF-8 BOM from .env file contents so the first variable is no longer silently lost when the file is saved with BOM (e.g. by some JetBrains IDEs on Windows) by [@​h1whelan] in #640
  • set_key now escapes backslashes, so values containing them (Windows paths, regular expressions) survive a write/read round-trip. Quoted values ending in an escaped backslash are no longer mis-parsed as an escaped quote, which used to swallow the following lines by [@​dchaudhari7177] in #680
  • dotenv run now prints a friendly error instead of a traceback when no command is given by [@​bbc2] in #606
  • Cache the parsed result for empty .env files so repeated dotenv_values/load_dotenv calls no longer re-read the file by [@​ReinerBRO] in #638

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 (
