Updates urllib3 from 2.4.0 to 2.6.3

Release notes

Sourced from urllib3's releases.

2.6.3

🚀 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.

Changes

Fixed a security issue where decompression-bomb safeguards of the streaming API were bypassed when HTTP redirects were followed. (CVE-2026-21441 reported by @D47A, 8.9 High, GHSA-38jv-5279-wg99)

Started treating Retry-After times greater than 6 hours as 6 hours by default. (urllib3/urllib3#3743)

Fixed urllib3.connection.VerifiedHTTPSConnection on Emscripten. (urllib3/urllib3#3752)

2.6.2

🚀 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.

Changes

Fixed HTTPResponse.read_chunked() to properly handle leftover data in the decoder's buffer when reading compressed chunked responses. (urllib3/urllib3#3734)

2.6.1

🚀 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.

Changes

Restore previously removed HTTPResponse.getheaders() and HTTPResponse.getheader() methods. (#3731)

2.6.0

🚀 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

Fixed a security issue where streaming API could improperly handle highly compressed HTTP content ("decompression bombs") leading to excessive resource consumption even when a small amount of data was requested. Reading small chunks of compressed data is safer and much more efficient now. (CVE-2025-66471 reported by @Cycloctane, 8.9 High, GHSA-2xpw-w6gg-jr37)

Fixed a security issue where an attacker could compose an HTTP response with virtually unlimited links in the Content-Encoding header, potentially leading to a denial of service (DoS) attack by exhausting system resources during decoding. The number of allowed chained encodings is now limited to 5. (CVE-2025-66418 reported by @illia-v, 8.9 High, GHSA-gm62-xv2j-4w53)

[!IMPORTANT]

If urllib3 is not installed with the optional urllib3[brotli] extra, but your environment contains a Brotli/brotlicffi/brotlipy package anyway, make sure to upgrade it to at least Brotli 1.2.0 or brotlicffi 1.2.0.0 to benefit from the security fixes and avoid warnings. Prefer using urllib3[brotli] to install a compatible Brotli package automatically.

Restore previously removed HTTPResponse.getheaders() and HTTPResponse.getheader() methods. ([#3731](https://github.com/urllib3/urllib3/issues/3731) <https://github.com/urllib3/urllib3/issues/3731>__)

2.6.0 (2025-12-05)

Security

Fixed a security issue where streaming API could improperly handle highly compressed HTTP content ("decompression bombs") leading to excessive resource consumption even when a small amount of data was requested. Reading small chunks of compressed data is safer and much more efficient now. (GHSA-2xpw-w6gg-jr37 <https://github.com/urllib3/urllib3/security/advisories/GHSA-2xpw-w6gg-jr37>__)

Fixed a security issue where an attacker could compose an HTTP response with virtually unlimited links in the Content-Encoding header, potentially leading to a denial of service (DoS) attack by exhausting system resources during decoding. The number of allowed chained encodings is now limited to 5. (GHSA-gm62-xv2j-4w53 <https://github.com/urllib3/urllib3/security/advisories/GHSA-gm62-xv2j-4w53>__)

.. caution::

If urllib3 is not installed with the optional urllib3[brotli] extra, but your environment contains a Brotli/brotlicffi/brotlipy package anyway, make sure to upgrade it to at least Brotli 1.2.0 or brotlicffi 1.2.0.0 to benefit from the security fixes and avoid warnings. Prefer using

Updates pip from 26.0.1 to 26.1

Changelog

Sourced from pip's changelog.

26.1 (2026-04-26)

Deprecations and Removals

Drop support for Python 3.9. ([#13795](https://github.com/pypa/pip/issues/13795) <https://github.com/pypa/pip/issues/13795>_)

Features

Add experimental support to read requirements from standardized pylock.toml files (-r pylock.toml). ([#13876](https://github.com/pypa/pip/issues/13876) <https://github.com/pypa/pip/issues/13876>_)

Allow --uploaded-prior-to to accept a duration in days (e.g., P3D for 3 days ago). ([#13674](https://github.com/pypa/pip/issues/13674) <https://github.com/pypa/pip/issues/13674>_)

Enhancements

Speed up dependency resolution when there are complex conflicts. ([#13859](https://github.com/pypa/pip/issues/13859) <https://github.com/pypa/pip/issues/13859>_)

Reduce memory usage when resolving large dependency trees. ([#13843](https://github.com/pypa/pip/issues/13843) <https://github.com/pypa/pip/issues/13843>_)

Emit a deprecation warning when pip imports an unexpected module after installation of a distribution has started. ([#13912](https://github.com/pypa/pip/issues/13912) <https://github.com/pypa/pip/issues/13912>_)

Allow URL constraints to apply to requirements with extras. ([#12018](https://github.com/pypa/pip/issues/12018) <https://github.com/pypa/pip/issues/12018>_)

Allow unpinned requirements to use hashes from constraints. Constraints like {name}=={version} --hash=... feeds into hash verification for a corresponding requirement. ([#9243](https://github.com/pypa/pip/issues/9243) <https://github.com/pypa/pip/issues/9243>_)

Improve conflict reports that involve direct URLs. ([#13932](https://github.com/pypa/pip/issues/13932) <https://github.com/pypa/pip/issues/13932>_)

Show all errors instead of first error for faulty dependency_groups definitions. ([#13917](https://github.com/pypa/pip/issues/13917) <https://github.com/pypa/pip/issues/13917>_)

Bug Fixes

Fix recovery hint for missing RECORD file to use --ignore-installed instead of --force-reinstall. ([#12645](https://github.com/pypa/pip/issues/12645) <https://github.com/pypa/pip/issues/12645>_)

Fix misleading error message when a constraint file cannot be opened. ([#13226](https://github.com/pypa/pip/issues/13226) <https://github.com/pypa/pip/issues/13226>_)

Show the filename rather than the full URL when downloading files from non-PyPI indexes in non-verbose mode. ([#13494](https://github.com/pypa/pip/issues/13494) <https://github.com/pypa/pip/issues/13494>_)

Remove the adjacent __pycache__ directory when a .py file is removed. ([#13725](https://github.com/pypa/pip/issues/13725) <https://github.com/pypa/pip/issues/13725>_)

Force UTF-8 encoding for :pep:723 metadata. ([#13861](https://github.com/pypa/pip/issues/13861) <https://github.com/pypa/pip/issues/13861>_)

Minor performance improvement when filtering candidates during resolution. ([#13916](https://github.com/pypa/pip/issues/13916) <https://github.com/pypa/pip/issues/13916>_)

Fix a hang on Windows when stdout is closed during verbose output. ([#13927](https://github.com/pypa/pip/issues/13927) <https://github.com/pypa/pip/issues/13927>_)

Common path prefixes are determined by path segment, not character by character. ([#13847](https://github.com/pypa/pip/issues/13847) <https://github.com/pypa/pip/issues/13847>_)

Fix installing .tar.gz source distributions that look like a zip file. ([#13867](https://github.com/pypa/pip/issues/13867) <https://github.com/pypa/pip/issues/13867>_)
