Changelog

Sourced from httpx's changelog.

0.28.1 (6th December, 2024)

• Fix SSL case where verify=False together with client side certificates.

0.28.0 (28th November, 2024)

Be aware that the default JSON request bodies now use a more compact representation. This is generally considered a prefered style, tho may require updates to test suites.

The 0.28 release includes a limited set of deprecations...

Deprecations:

We are working towards a simplified SSL configuration API.

For users of the standard verify=True or verify=False cases, or verify=<ssl_context> case this should require no changes. The following cases have been deprecated...

• The verify argument as a string argument is now deprecated and will raise warnings.
• The cert argument is now deprecated and will raise warnings.

Our revised SSL documentation covers how to implement the same behaviour with a more constrained API.

The following changes are also included:

• The deprecated proxies argument has now been removed.
• The deprecated app argument has now been removed.
• JSON request bodies use a compact representation. (#3363)
• Review URL percent escape sets, based on WHATWG spec. (#3371, #3373)
• Ensure certifi and httpcore are only imported if required. (#3377)
• Treat socks5h as a valid proxy scheme. (#3178)
• Cleanup Request() method signature in line with client.request() and httpx.request(). (#3378)
• Bugfix: When passing params={}, always strictly update rather than merge with an existing querystring. (#3364)

0.27.2 (27th August, 2024)

Fixed

• Reintroduced supposedly-private URLTypes shortcut. (#2673)

0.27.1 (27th August, 2024)

Added

• Support for zstd content decoding using the python zstandard package is added. Installable using httpx[zstd]. (#3139)

Fixed

• Improved error messaging for InvalidURL exceptions. (#3250)
• Fix app type signature in ASGITransport. (#3109)

0.27.0 (21st February, 2024)

Updates typing-extensions to 4.16.0

Release notes

Sourced from typing-extensions's releases.

4.16.0

No changes since 4.16.0rc2.

Changes since 4.15.0:

• Make typing_extensions.TypeAliasType's __module__ attribute writable. Backport of CPython PR #149172.
• Fix setting of __required_keys__ and __optional_keys__ when inheriting keys with the same name.
• Add support for AsyncIterator, io.Reader, io.Writer and os.PathLike protocols as bases for other protocols.
• Fix incorrect behaviour on Python 3.9 and Python 3.10 that meant that calling isinstance with typing_extensions.Concatenate[...] or typing_extensions.Unpack[...] as the first argument could have a different result in some situations depending on whether or not a profiling function had been set using sys.setprofile. This affected both CPython and PyPy implementations. Patch by Brian Schubert.
• Fix __init_subclass__() behavior in the presence of multiple inheritance involving an @deprecated-decorated base class. Backport of CPython PR #138210 by Brian Schubert.
• Raise TypeError when attempting to subclass typing_extensions.ParamSpec on Python 3.9. The typing implementation has always raised an error, and the typing_extensions implementation has raised an error on Python 3.10+ since typing_extensions v4.6.0. Patch by Brian Schubert.
• Add the bound, covariant, contravariant, and infer_variance parameters to TypeVarTuple.
• Officially support the bound, covariant, contravariant and infer_variance parameters to ParamSpec. Improve the validation of these parameters at runtime.
• Rename typing_extensions.Sentinel to typing_extensions.sentinel, following the name that has been adopted for builtins.sentinel on Python 3.15. typing_extensions.Sentinel is retained as a soft-deprecated alias for backwards compatibility.
• Add support for pickling sentinels.
• Sentinels now preserve their identity when copied or deep-copied.
• Deprecate passing name as a keyword argument or repr as a positional argument to the sentinel constructor.
• The default repr of a sentinel X = sentinel("X") is now X rather than <X>.
• Deprecate arbitrary attribute assignments to sentinels.
• Deprecate subclassing sentinels.
• Add support for Python 3.15.
• Avoid a DeprecationWarning when deprecated is applied to a coroutine function on Python 3.14.0.

Note

Low Risk
Dependency constraint-only change with no code edits; main residual risk is upstream behavior changes (e.g. httpx 0.28 SSL/JSON semantics) surfacing in integration tests.

Overview
Raises minimum production dependency floors in pyproject.toml only: httpx from >=0.23.0 to >=0.28.1, pydantic from >=2.0 to >=2.13.5, and typing_extensions from >=4.6 to >=4.16.0. Upper bounds are unchanged (httpx still <0.29.0, pydantic still <3).

Installs and CI will now resolve to newer patch/minor releases within those ranges. No application or test code is modified; the SDK continues to use httpx clients and Pydantic validation as before.

Raised floors break library consumers

Medium Severity

The new lower bounds require pydantic 2.13.5, httpx 0.28.1, and typing_extensions 4.16.0. Those versions were already allowed by the previous ranges, so this change drops support for still-compatible releases rather than merely permitting newer ones. Downstream installs that pin older valid versions will fail.

Lock file lags new constraints

Medium Severity

uv.lock still pins pydantic 2.13.4 and typing-extensions 4.15.0, and its metadata still records the old specifiers. Those locked versions do not satisfy the new pyproject.toml floors, so frozen uv installs and lock checks will fail.
