Equests

-------------------

**Bugfixes**

- Fixed parsing issue that resulted in the `auth` component being
dropped from proxy URLs. (6028)

-------------------

**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.

-------------------

**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:

shell
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)

-------------------

**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.

-------------------

**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.

-------------------

**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)
