Version 26.5.1

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)

Version 26.5.0

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)

Updates python-dotenv to 1.2.2

Release notes

Sourced from python-dotenv's releases.

v1.2.2

Added

• Support for Python 3.14, including the free-threaded (3.14t) build. (#)

Changed

• The dotenv run command now forwards flags directly to the specified command by @​bbc2 in theskumar/python-dotenv#607
• Improved documentation clarity regarding override behavior and the reference page.
• Updated PyPy support to version 3.11.
• Documentation for FIFO file support.
• Support for Python 3.9.

Fixed

• Improved set_key and unset_key behavior when interacting with symlinks by @​bbc2 in #790c5
• Corrected the license specifier and added missing Python 3.14 classifiers in package metadata by @​JYOuyang in theskumar/python-dotenv#590

Breaking Changes

• dotenv.set_key and dotenv.unset_key used to follow symlinks in some situations. This is no longer the case. For that behavior to be restored in all cases, follow_symlinks=True should be used.

• In the CLI, set and unset used to follow symlinks in some situations. This is no longer the case.

• dotenv.set_key, dotenv.unset_key and the CLI commands set and unset used to reset the file mode of the modified .env file to 0o600 in some situations. This is no longer the case: The original mode of the file is now preserved. Is the file needed to be created or wasn't a regular file, mode 0o600 is used.

Misc

• skip 000 permission tests for root user by @​burnout-projects in theskumar/python-dotenv#561
• Bump actions/checkout from 5 to 6 in the github-actions group by @​dependabot[bot] in theskumar/python-dotenv#593
• Add Windows testing to CI by @​bbc2 in theskumar/python-dotenv#604
• Improve workflow efficiency with best practices by @​theskumar in theskumar/python-dotenv#609
• Remove the use of sh in tests by @​bbc2 in theskumar/python-dotenv#612

New Contributors

• @​JYOuyang made their first contribution in theskumar/python-dotenv#590
• @​burnout-projects made their first contribution in theskumar/python-dotenv#561
• @​cpackham-atlnz made their first contribution in theskumar/python-dotenv#597

Updates idna to 3.15

Changelog

Sourced from idna's changelog.

3.15 (2026-05-12)

• Enforce DNS-length cap on individual labels early in check_label, short-circuiting contextual-rule processing for oversized input while staying compatible with UTS 46 usage.
• Tidy core helpers: hoist bidi category sets to module-level frozensets (avoiding per-codepoint list construction), simplify length checks, and reuse the shared _unicode_dots_re from idna.core in the codec module.
• Use raise ... from err for proper exception chaining and switch internal string formatting to f-strings.
• Allow flit_core 4.x in the build backend.
• Expand the ruff lint set (flake8-bugbear, flake8-simplify, pyupgrade, perflint) and apply the surfaced fixes; pin lint CI to Python 3.14.
• Add Dependabot configuration for GitHub Actions.
• Convert README and HISTORY from reStructuredText to Markdown.
• Reference CVE-2026-45409 for the 3.14 advisory in place of the initial GHSA identifier.

Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for contributions to this release.

3.14 (2026-05-10)

• Removed opportunity to process long inputs into quadratic time by rejecting oversize inputs up-front. Closes a bypass of the CVE-2024-3651 mitigation. [CVE-2026-45409]

Thanks to Stan Ulbrych for reporting the issue.

3.13 (2026-04-22)

• Correct classification error for codepoint U+A7F1

3.12 (2026-04-21)

• Update to Unicode 17.0.0.
• Issue a deprecation warning for the transitional argument.
• Added lazy-loading to provide some performance improvements.
• Removed vestiges of code related to Python 2 support, including segmentation of data structures specific to Jython.

Thanks to Rodrigo Nogueira for contributions to this release.

3.11 (2025-10-12)

• Update to Unicode 16.0.0, including significant changes to UTS46 processing. As a result of Unicode ending support for it, transitional processing no longer has an effect and returns the same result.

Updates lxml to 6.1.1

Changelog

Sourced from lxml's changelog.

6.1.1 (2026-05-18)

Bugs fixed

• The known link attributes in lxml.html.defs.link_attrs were missing xlink:href, which can be used for URL bypass attacks in embedded SVG/MathML/etc. content. https://github.com/fedora-python/lxml_html_clean/security/advisories/GHSA-4jhm-jv67-739f

• The Linux wheels use a patched libxslt 1.1.43, fixing CVE-2025-7424 and CVE-2025-11731.

• The Windows wheels use libxslt 1.1.45, fixing CVE-2025-7424 and CVE-2025-11731.

6.1.0 (2026-04-17)

This release fixes a possible external entity injection (XXE) vulnerability in iterparse() and the ETCompatXMLParser.

Features added

• GH#486: The HTML ARIA accessibility attributes were added to the set of safe attributes in lxml.html.defs. This allows lxml_html_clean to pass them through. Patch by oomsveta.

• The default chunk size for reading from file-likes in iterparse() is now configurable with a new chunk_size argument.

Bugs fixed

• LP#2146291: The resolve_entities option was still set to True for iterparse and ETCompatXMLParser, allowing for external entity injection (XXE) when using these parsers without setting this option explicitly. The default was now changed to 'internal' only (as for the normal XML and HTML parsers since lxml 5.0). Issue found by Sihao Qiu as CVE-2026-41066.

6.0.4 (2026-04-12)

Bugs fixed

• LP#2148019: Spurious MemoryError during namespace cleanup.

Updates requests to 2.34.2

Release notes

Sourced from requests's releases.

v2.34.2

2.34.2 (2026-05-14)

• 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)

2.34.2 (2026-05-14)

• 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)

2.34.1 (2026-05-13)

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)

2.34.0 (2026-05-11)

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)

Updates urllib3 to 2.7.0

Release notes

Sourced from urllib3's releases.

2.7.0

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project after a sharp decline in financial support. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Security

Addressed high-severity security issues. Impact was limited to specific use cases detailed in the accompanying advisories; overall user exposure was estimated to be marginal.

• Decompression-bomb safeguards of the streaming API were bypassed:

  1. When HTTPResponse.drain_conn() was called after the response had been read and decompressed partially. (Reported by @​Cycloctane)
  2. During the second HTTPResponse.read(amt=N) or HTTPResponse.stream(amt=N) call when the response was decompressed using the official Brotli library. (Reported by @​kimkou2024)

  See GHSA-mf9v-mfxr-j63j for details.

• HTTP pools created using ProxyManager.connection_from_url did not strip sensitive headers specified in Retry.remove_headers_on_redirect when redirecting to a different host. (GHSA-qccp-gfcp-xxvc reported by @​christos-spearbit)

Deprecations and Removals

• Used FutureWarning instead of DeprecationWarning for better visibility of existing deprecation notices. Rescheduled the removal of deprecated features to version 3.0. (urllib3/urllib3#3763)
• Removed support for end-of-life Python 3.9. (urllib3/urllib3#3720)
• Removed support for end-of-life PyPy3.10. (urllib3/urllib3#4979)
• Bumped the minimum supported pyOpenSSL version to 19.0.0. (urllib3/urllib3#3777)

Bugfixes

• Fixed a bug where HTTPResponse.read(amt=None) was ignoring decompressed data buffered from previous partial reads. (urllib3/urllib3#3636)
• Fixed a bug...
