2.27.0 (2022-01-03)

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.
