Release Notes

v2.31.0

Compare Source

Security

• Versions of Requests between v2.3.0 and v2.30.0 are vulnerable to potential
  forwarding of Proxy-Authorization headers to destination servers when
  following HTTPS redirects.

  When proxies are defined with user info (https://user:pass@proxy:8080), Requests
  will construct a Proxy-Authorization header that is attached to the request to
  authenticate with the proxy.

  In cases where Requests receives a redirect response, it previously reattached
  the Proxy-Authorization header incorrectly, resulting in the value being
  sent through the tunneled connection to the destination server. Users who rely on
  defining their proxy credentials in the URL are strongly encouraged to upgrade
  to Requests 2.31.0+ to prevent unintentional leakage and rotate their proxy
  credentials once the change has been fully deployed.

  Users who do not use a proxy or do not supply their proxy credentials through
  the user information portion of their proxy URL are not subject to this
  vulnerability.

  Full details can be read in our Github Security Advisory
  and CVE-2023-32681.

v2.30.0

Compare Source

Dependencies

• ⚠️ Added support for urllib3 2.0. ⚠️

  This may contain minor breaking changes so we advise careful testing and
  reviewing https://urllib3.readthedocs.io/en/latest/v2-migration-guide.html
  prior to upgrading.

  Users who wish to stay on urllib3 1.x can pin to urllib3<2.

v2.29.0

Compare Source

Improvements

• Requests now defers chunked requests to the urllib3 implementation to improve
  standardization. (#​6226)
• Requests relaxes header component requirements to support bytes/str subclasses. (#​6356)

v2.28.2

Compare Source

Dependencies

• Requests now supports charset_normalizer 3.x. (#​6261)

Bugfixes

• Updated MissingSchema exception to suggest https scheme rather than http. (#​6188)

v2.28.1

Compare Source

Improvements

• Speed optimization in iter_content with transition to yield from. (#​6170)

Dependencies

• Added support for chardet 5.0.0 (#​6179)
• Added support for charset-normalizer 2.1.0 (#​6169)

v2.28.0

Compare Source

Deprecations

• ⚠️ Requests has officially dropped support for Python 2.7. ⚠️ (#​6091)
• Requests has officially dropped support for Python 3.6 (including pypy3.6). (#​6091)

Improvements

• Wrap JSON parsing issues in Request's JSONDecodeError for payloads without
  an encoding to make json() API consistent. (#​6097)
• Parse header components consistently, raising an InvalidHeader error in
  all invalid cases. (#​6154)
• Added provisional 3.11 support with current beta build. (#​6155)
• Requests got a makeover and we decided to paint it black. (#​6095)

Bugfixes

• Fixed bug where setting CURL_CA_BUNDLE to an empty string would disable
  cert verification. All Requests 2.x versions before 2.28.0 are affected. (#​6074)
• Fixed urllib3 exception leak, wrapping urllib3.exceptions.SSLError with
  requests.exceptions.SSLError for content and iter_content. (#​6057)
• Fixed issue where invalid Windows registry entries caused proxy resolution
  to raise an exception rather than ignoring the entry. (#​6149)
• Fixed issue where entire payload could be included in the error message for
  JSONDecodeError. (#​6036)

v2.27.1

Compare Source

Bugfixes

• Fixed parsing issue that resulted in the auth component being
  dropped from proxy URLs. (#​6028)

v2.27.0

Compare Source

Improvements

• Officially added support for Python 3.10. (#​5928)

• Added a requests.exceptions.JSONDecodeError to unify JSON exceptions between
  Python 2 and 3. This gets raised in the response.json() method, and is
  backwards compatible as it inherits from previously thrown exceptions.
  Can be caught from requests.exceptions.RequestException as well. (#​5856)

• Improved error text for misnamed InvalidSchema and MissingSchema
  exceptions. This is a temporary fix until exceptions can be renamed
  (Schema->Scheme). (#​6017)

• Improved proxy parsing for proxy URLs missing a scheme. This will address
  recent changes to urlparse in Python 3.9+. (#​5917)

Bugfixes

• Fixed defect in extract_zipped_paths which could result in an infinite loop
  for some paths. (#​5851)

• Fixed handling for AttributeError when calculating length of files obtained
  by Tarfile.extractfile(). (#​5239)

• Fixed urllib3 exception leak, wrapping urllib3.exceptions.InvalidHeader with
  requests.exceptions.InvalidHeader. (#​5914)

• Fixed bug where two Host headers were sent for chunked requests. (#​5391)

• Fixed regression in Requests 2.26.0 where Proxy-Authorization was
  incorrectly stripped from all requests sent with Session.send. (#​5924)

• Fixed performance regression in 2.26.0 for hosts with a large number of
  proxies available in the environment. (#​5924)

• Fixed idna exception leak, wrapping UnicodeError with
  requests.exceptions.InvalidURL for URLs with a leading dot (.) in the
  domain. (#​5414)

Deprecations

• Requests support for Python 2.7 and 3.6 will be ending in 2022. While we
  don't have exact dates, Requests 2.27.x is likely to be the last release
  series providing support.

v2.26.0

Compare Source

Improvements

• Requests now supports Brotli compression, if either the brotli or
  brotlicffi package is installed. (#​5783)

• Session.send now correctly resolves proxy configurations from both
  the Session and Request. Behavior now matches Session.request. (#​5681)

Bugfixes

• Fixed a race condition in zip extraction when using Requests in parallel
  from zip archive. (#​5707)

Dependencies

• Instead of chardet, use the MIT-licensed charset_normalizer for Python3
  to remove license ambiguity for projects bundling requests. If chardet
  is already installed on your machine it will be used instead of charset_normalizer
  to keep backwards compatibility. (#​5797)

  You can also install chardet while installing requests by
  specifying [use_chardet_on_py3] extra as follows:

  pip install "requests[use_chardet_on_py3]"

  Python2 still depends upon the chardet module.

• Requests now supports idna 3.x on Python 3. idna 2.x will continue to
  be used on Python 2 installations. (#​5711)

Deprecations

• The requests[security] extra has been converted to a no-op install.
  PyOpenSSL is no longer the recommended secure option for Requests. (#​5867)

• Requests has officially dropped support for Python 3.5. (#​5867)

v2.25.1

Compare Source

Bugfixes

• Requests now treats application/json as utf8 by default. Resolving
  inconsistencies between r.text and r.json output. (#​5673)

Dependencies

• Requests now supports chardet v4.x.

v2.25.0

Compare Source

Improvements

• Added support for NETRC environment variable. (#​5643)

Dependencies

• Requests now supports urllib3 v1.26.

Deprecations

• Requests v2.25.x will be the last release series with support for Python 3.5.
• The requests[security] extra is officially deprecated and will be removed
  in Requests v2.26.0.

v2.24.0

Compare Source

Improvements

• pyOpenSSL TLS implementation is now only used if Python
  either doesn't have an ssl module or doesn't support
  SNI. Previously pyOpenSSL was unconditionally used if available.
  This applies even if pyOpenSSL is installed via the
  requests[security] extra (#​5443)

• Redirect resolution should now only occur when
  allow_redirects is True. (#​5492)

• No longer perform unnecessary Content-Length calculation for
  requests that won't use it. (#​5496)

v2.23.0

Compare Source

Improvements

• Remove defunct reference to prefetch in Session __attrs__ (#​5110)

Bugfixes

• Requests no longer outputs password in basic auth usage warning. (#​5099)

Dependencies

• Pinning for chardet and idna now uses major version instead of minor.
  This hopefully reduces the need for releases every time a dependency is updated.

v2.22.0

Compare Source

Dependencies

• Requests now supports urllib3 v1.25.2.
  (note: 1.25.0 and 1.25.1 are incompatible)

Deprecations

• Requests has officially stopped support for Python 3.4.

v2.21.0

Compare Source

Dependencies

• Requests now supports idna v2.8.

  redirects using default ports (http/80, https/443).

v2.20.0

Compare Source

Bugfixes

• Content-Type header parsing is now case-insensitive (e.g.
  charset=utf8 v Charset=utf8).
• Fixed exception leak where certain redirect urls would raise
  uncaught urllib3 exceptions.
• Requests removes Authorization header from requests redirected
  from https to http on the same hostname. (CVE-2018-18074)
• should_bypass_proxies now handles URIs without hostnames (e.g.
  files).

Dependencies

• Requests now supports urllib3 v1.24.

Deprecations

• Requests has officially stopped support for Python 2.6.

v2.19.1

Compare Source

Compare Source

Improvements

• Warn user about possible slowdown when using cryptography version
  < 1.3.4

  raises an exception.
• Calling copy on a RequestsCookieJar will now preserve the cookie
  policy correctly.
