Release Notes

urllib3/urllib3 (urllib3)

`v2.6.3`

Compare Source

==================

Fixed a high-severity security issue where decompression-bomb safeguards of
the streaming API were bypassed when HTTP redirects were followed.
(GHSA-38jv-5279-wg99 <https://github.com/urllib3/urllib3/security/advisories/GHSA-38jv-5279-wg99>__)
Started treating Retry-After times greater than 6 hours as 6 hours by
default. (#3743 <https://github.com/urllib3/urllib3/issues/3743>__)
Fixed urllib3.connection.VerifiedHTTPSConnection on Emscripten.
(#3752 <https://github.com/urllib3/urllib3/issues/3752>__)

`v2.6.2`

Compare Source

==================

Fixed HTTPResponse.read_chunked() to properly handle leftover data in
the decoder's buffer when reading compressed chunked responses.
(#3734 <https://github.com/urllib3/urllib3/issues/3734>__)

`v2.6.1`

Compare Source

==================

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

`v2.6.0`

Compare Source

==================

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
urllib3[brotli] to install a compatible Brotli package automatically.
If you use custom decompressors, please make sure to update them to
respect the changed API of urllib3.response.ContentDecoder.

Features

Enabled retrieval, deletion, and membership testing in HTTPHeaderDict using bytes keys. (#3653 <https://github.com/urllib3/urllib3/issues/3653>__)
Added host and port information to string representations of HTTPConnection. (#3666 <https://github.com/urllib3/urllib3/issues/3666>__)
Added support for Python 3.14 free-threading builds explicitly. (#3696 <https://github.com/urllib3/urllib3/issues/3696>__)

Removals

Removed the HTTPResponse.getheaders() method in favor of HTTPResponse.headers.
Removed the HTTPResponse.getheader(name, default) method in favor of HTTPResponse.headers.get(name, default). (#3622 <https://github.com/urllib3/urllib3/issues/3622>__)

Bugfixes

Fixed redirect handling in urllib3.PoolManager when an integer is passed
for the retries parameter. (#3649 <https://github.com/urllib3/urllib3/issues/3649>__)
Fixed HTTPConnectionPool when used in Emscripten with no explicit port. (#3664 <https://github.com/urllib3/urllib3/issues/3664>__)
Fixed handling of SSLKEYLOGFILE with expandable variables. (#3700 <https://github.com/urllib3/urllib3/issues/3700>__)

Misc

Changed the zstd extra to install backports.zstd instead of zstandard on Python 3.13 and before. (#3693 <https://github.com/urllib3/urllib3/issues/3693>__)
Improved the performance of content decoding by optimizing BytesQueueBuffer class. (#3710 <https://github.com/urllib3/urllib3/issues/3710>__)
Allowed building the urllib3 package with newer setuptools-scm v9.x. (#3652 <https://github.com/urllib3/urllib3/issues/3652>__)
Ensured successful urllib3 builds by setting Hatchling requirement to >= 1.27.0. (#3638 <https://github.com/urllib3/urllib3/issues/3638>__)

`v2.5.0`

Compare Source

==================

Features

Added support for the compression.zstd module that is new in Python 3.14.
See PEP 784 <https://peps.python.org/pep-0784/>_ for more information. (#3610 <https://github.com/urllib3/urllib3/issues/3610>__)
Added support for version 0.5 of hatch-vcs (#3612 <https://github.com/urllib3/urllib3/issues/3612>__)

Bugfixes

Fixed a security issue where restricting the maximum number of followed
redirects at the urllib3.PoolManager level via the retries parameter
did not work.
Made the Node.js runtime respect redirect parameters such as retries
and redirects.
Raised exception for HTTPResponse.shutdown on a connection already released to the pool. (#3581 <https://github.com/urllib3/urllib3/issues/3581>__)
Fixed incorrect CONNECT statement when using an IPv6 proxy with connection_from_host. Previously would not be wrapped in []. (#3615 <https://github.com/urllib3/urllib3/issues/3615>__)
