Release Notes

psf/requests

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 entires 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)
