v10.3.0

Compare Source

v26.5.1

Compare Source

Stable style

• Fix unstable formatting of annotated assignments whose subscript annotation contains
  an inline comment (e.g. x: list[ # pyright: ignore[...]) (#​5130)
• Preserve inline comments (including # type: ignore) immediately before a
  # fmt: skip line, avoiding AST equivalence failures (#​5139)

Packaging

• Correct the version in the published executables (#​5137)

Documentation

• Add Neovim integration guide covering conform.nvim, ALE, and simple command approaches
  (#​5124)

v26.5.0

Compare Source

Highlights

• Add support for unpacking in comprehensions (PEP 798) and for lazy imports (PEP 810),
  both new syntactic features in Python 3.15 (#​5048)
• Python 3.15 is now supported. Compiled wheels are not yet provided for Python 3.15, so
  performance may be slower than on existing Python versions. Wheels will be provided
  once Python 3.15 is later in its release cycle. (#​5127)

Stable style

• Fix # fmt: skip being ignored in nested if expressions with parenthesized in
  clauses (#​4903)
• Add syntactic support for Python 3.15 (#​5048)
• Fix crash when an f-string follows a # fmt: off comment inside brackets (#​5097)
• Preserve multiline compound statement headers when # fmt: skip is placed on the
  colon line (#​5117)

Preview style

• Improve heuristics around whether blank lines should appear before, within and after
  groups of same-name decorated functions (such as @overload groups) in .pyi stub
  files (#​5021)
• Fix blank lines being removed between a function and a decorated class in .pyi stub
  files (#​5092)
• Prevent string merger from creating unsplittable long lines when a pragma comment
  (e.g. # type: ignore) follows the closing bracket (#​5096)

Packaging

• Run CI on 3.15 (#​5127)

Output

• Improve parse error readability by showing multi-line output with an error pointer.
  (#​5068)
• Add SourceASTParseError to distinguish source parse failures from internal safety
  errors, improving error reporting when Black's lenient parser accepts input that
  ast.parse() rejects (#​5080)

Blackd

• Return HTTP 400 (Bad Request) for source parse failures instead of HTTP 500, keeping
  HTTP 500 only for genuine internal safety errors (#​5080)

Integrations

• Added documentation for doctest formatting tools and updated the integrations index to
  match (#​4916)

Documentation

• Use "Version X.Y.Z" headings in changelog for stable permalink anchors on ReadTheDocs
  (#​5063)
• Note in the editor integrations that the SublimeText sublack plugin is archived and
  unmaintained (#​5082)

v7.14.0

Compare Source

• Feature: now when running one of the reporting commands, if there are
  parallel data files that need combining, they will be implicitly combined
  before creating the report. There is no option to avoid the combination; let
  us know if you have a use case that requires it. Thanks, Tim Hatch <pull 2162_>. Closes issue 1781.

• Fix: the output from combine was too verbose, listing each file
  considered. Now it shows a single line with the counts of files combined,
  files skipped, and files with errors. The -q flag suppresses this line.
  The old detailed lines are available with the new --debug=combine option.

• Fix: running a Python file through a symlink now sets the sys.path correctly,
  matching regular Python behavior. Fixes issue 2157_.

• Fix: Collector.flush_data could fail with "RuntimeError: Set changed
  size during iteration" when a tracer in another thread added a line to the
  per-file set that add_lines (or add_arcs) was iterating. The values
  passed to CoverageData are now snapshotted via dict.copy() and
  set.copy(), which are atomic under the GIL. Thanks, Alex Vandiver <pull 2165_>_.

• Fix: the soft keyword lazy is now bolded in HTML reports.

• We are no longer testing eventlet support. Eventlet started issuing stern
  deprecation warnings that break our tests. Our support code is still there.

Full Changelog: v5.0.0...v5.1.0

v2.34.2

Compare Source

• Moved headers input type back to Mapping to avoid invariance issues
  with MutableMapping and inferred dict types. Users calling
  Request.headers.update() may need to narrow typing in their code. (#​7441)

v2.34.1

Compare Source

Bugfixes

• Widened json input type from dict and list to Mapping
  and Sequence. (#​7436)
• Changed headers input type to MutableMapping and removed None from
  Request.headers typing to improve handling for users. (#​7431)
• Response.reason moved from str | None to str to improve handling
  for users. (#​7437)
• Fixed a bug where some bodies with custom __getattr__ implementations
  weren't being properly detected as Iterables. (#​7433)

v2.34.0

Compare Source

Announcements

• Requests 2.34.0 introduces inline types, replacing those provided by
  typeshed. Public API types should be fully compatible with mypy, pyright,
  and ty. We believe types are comprehensive but if you find issues, please
  report them to the pinned tracking issue.

  Special thanks to @​bastimeyer, @​cthoyt, @​edgarrmondragon, and @​srittau for
  helping review and test the types ahead of the release. (#​7272)

Improvements

• Digest Auth hashing algorithms have added usedforsecurity=False to clarify
  security considerations. (#​7310)
• Requests added support for Python 3.15 based on beta1. Downstream projects
  should be able to start testing prior to its release in October. (#​7422)
• Requests added support for Python 3.14t. (#​7419)

Bugfixes

• Response.history no longer contains a reference to itself, preventing
  accidental looping when traversing the history list. (#​7328)
• Requests no longer performs greedy matching on no_proxy domains. The
  proxy_bypass implementation has been updated with CPython's fix from
  bpo-39057. (#​7427)
• Requests no longer incorrectly strips duplicate leading slashes in
  URI paths. This should address user issues with specific presigned
  URLs. Note the full fix requires urllib3 2.7.0+. (#​7315)

v0.26.1

Compare Source

• Added Spanish translation of the README (README.es.rst)
• When both content_type and headers['content-type'] are in a response mock file,
  content_type is now used.
• Added strict_match to urlencoded_params_matcher, enabling partial request parameter
  matching.
