46.0.7 - 2026年04月07日

* **SECURITY ISSUE**: Fixed an issue where non-contiguous buffers could be
 passed to APIs that accept Python buffers, which could lead to buffer
 overflow. **CVE-2026-39892**
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.5.6.
.. _v46-0-6:

3.15 (2026年05月12日)

• 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年05月10日)

• 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年04月22日)

• Correct classification error for codepoint U+A7F1

3.12 (2026年04月21日)

• 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.

2.7.0

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~40,000ドル 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 where HTTPResponse.read() could cache only part of the response after a partial read when cache_content=True. (urllib3/urllib3#4967)
• Fixed HTTPResponse.stream() and HTTPResponse.read_chunked() to handle amt=0. (urllib3/urllib3#3793)
• Updated _TYPE_BODY type alias to include missing Iterable[str], matching the documented and runtime behavior of chunked request bodies. (urllib3/urllib3#3798)
• Fixed LocationParseError when paths resembling schemeless URIs were passed to HTTPConnectionPool.urlopen(). (urllib3/urllib3#3352)
• Fixed BaseHTTPResponse.readinto() type annotation to accept memoryview in addition to bytearray, matching the io.RawIOBase.readinto contract and enabling use with io.BufferedReader without type errors. (urllib3/urllib3#3764)
