Moved headers input type back to Mapping to avoid invariance issues
with MutableMapping and inferred dict types. Users calling Request.headers.update() may need to narrow typing in their code. (#7441)
Requests 2.34.0 introduces inline types, replacing those provided by
typeshed. Public API types should be fully compatible with mypy, pyright,
and ty. We believe types are comprehensive but if you find issues, please
report them to the pinned tracking issue.
Response.history no longer contains a reference to itself, preventing
accidental looping when traversing the history list. (#7328)
Requests no longer performs greedy matching on no_proxy domains. The
proxy_bypass implementation has been updated with CPython's fix from
bpo-39057. (#7427)
Requests no longer incorrectly strips duplicate leading slashes in
URI paths. This should address user issues with specific presigned
URLs. Note the full fix requires urllib3 2.7.0+. (#7315)
📣 Requests is adding inline types. If you have a typed code base that
uses Requests, please take a look at #7271. Give it a try, and report
any gaps or feedback you may have in the issue. 📣
Security
CVE-2026-25645 requests.utils.extract_zipped_paths now extracts
contents to a non-deterministic location to prevent malicious file
replacement. This does not affect default usage of Requests, only
applications calling the utility function directly.
Improvements
Migrated to a PEP 517 build system using setuptools. (#7012)
Bugfixes
Fixed an issue where an empty netrc entry could cause
malformed authentication to be applied to Requests on
Python 3.11+. (#7205)
Deprecations
Dropped support for Python 3.9 following its end of support. (#7196)
The SSLContext caching feature originally introduced in 2.32.0 has created
a new class of issues in Requests that have had negative impact across a number
of use cases. The Requests team has decided to revert this feature as long term
maintenance of it is proving to be unsustainable in its current iteration.
Deprecations
Added support for Python 3.14.
Dropped support for Python 3.8 following its end of support.
CVE-2024-47081 Fixed an issue where a maliciously crafted URL and trusted
environment will retrieve credentials for the wrong hostname/machine from a
netrc file.
Improvements
Numerous documentation improvements
Deprecations
Added support for pypy 3.11 for Linux and macOS.
Dropped support for pypy 3.9 following its end of support.
To provide a more stable migration for custom HTTPAdapters impacted
by the CVE changes in 2.32.0, we've renamed _get_connection to
a new public API, get_connection_with_tls_context. Existing custom
HTTPAdapters will need to migrate their code to use this new API. get_connection is considered deprecated in all versions of Requests>=2.32.0.
A minimal (2-line) example has been provided in the linked PR to ease
migration, but we strongly urge users to evaluate if their custom adapter
is subject to the same issue described in CVE-2024-35195. (#6710)
verify=True now reuses a global SSLContext which should improve
request time variance between first and subsequent requests. It should
also minimize certificate load time on Windows systems when using a Python
version built with OpenSSL 3.x. (#6667)
Requests now supports optional use of character detection
(chardet or charset_normalizer) when repackaged or vendored.
This enables pip and other projects to minimize their vendoring
surface area. The Response.text() and apparent_encoding APIs
will default to utf-8 if neither library is present. (#6702)
Bugfixes
Fixed bug in length detection where emoji length was incorrectly
calculated in the request content-length. (#6589)
Fixed deserialization bug in JSONDecodeError. (#6629)
Fixed bug where an extra leading / (path separator) could lead
urllib3 to unnecessarily reparse the request URI. (#6644)
Deprecations
Requests has officially added support for CPython 3.12 (#6503)
Requests has officially added support for PyPy 3.9 and 3.10 (#6641)
Requests has officially dropped support for CPython 3.7 (#6642)
Requests has officially dropped support for PyPy 3.7 and 3.8 (#6641)
Documentation
Various typo fixes and doc improvements.
Packaging
Requests has started adopting some modern packaging practices.
The source files for the projects (formerly requests) is now located
in src/requests in the Requests sdist. (#6506)
Starting in Requests 2.33.0, Requests will migrate to a PEP 517 build system
using hatchling. This should not impact the average user, but extremely old
versions of packaging utilities may have issues with the new packaging format.
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.
⚠️ 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)
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.
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)
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)
It is now possible to pass no_proxy as a key to the proxies
dictionary to provide handling similar to the NO_PROXY environment
variable.
When users provide invalid paths to certificate bundle files or
directories Requests now raises IOError, rather than failing at
the time of the HTTPS request with a fairly inscrutable certificate
validation error.
The behavior of SessionRedirectMixin was slightly altered. resolve_redirects will now detect a redirect by calling get_redirect_target(response) instead of directly querying Response.is_redirect and Response.headers['location']. Advanced
users will be able to process malformed redirects more easily.
Changed the internal calculation of elapsed request time to have
higher resolution on Windows.
Added win_inet_pton as conditional dependency for the [socks]
extra on Windows with Python 2.7.
Changed the proxy bypass implementation on Windows: the proxy bypass
check doesn't use forward and reverse DNS requests anymore
URLs with schemes that begin with http but are not http or https no longer have their host parts forced to lowercase.
Bugfixes
Much improved handling of non-ASCII Location header values in
redirects. Fewer UnicodeDecodeErrors are encountered on Python 2,
and Python 3 now correctly understands that Latin-1 is unlikely to
be the correct encoding.
If an attempt to seek file to find out its length fails, we now
appropriately handle that by aborting our content-length
calculations.
Restricted HTTPDigestAuth to only respond to auth challenges made
on 4XX responses, rather than to all auth challenges.
Fixed some code that was firing DeprecationWarning on Python 3.6.
The dismayed person emoticon (/o\\) no longer has a big head. I'm
sure this is what you were all worrying about most.
Miscellaneous
Updated bundled urllib3 to v1.21.1.
Updated bundled chardet to v3.0.2.
Updated bundled idna to v2.5.
Updated bundled certifi to 2017.4.17.

[Compare Source](https://github.com/psf/requests/compare/v2.32.3...v2.32.4)
**Security**
- CVE-2024-47081 Fixed an issue where a maliciously crafted URL and trusted
environment will retrieve credentials for the wrong hostname/machine from a
netrc file.
**Improvements**
- Numerous documentation improvements
**Deprecations**
- Added support for pypy 3.11 for Linux and macOS.
- Dropped support for pypy 3.9 following its end of support.
### [`v2.32.3`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2323-2024-05-29)
[Compare Source](https://github.com/psf/requests/compare/v2.32.2...v2.32.3)
**Bugfixes**
- Fixed bug breaking the ability to specify custom SSLContexts in sub-classes of
HTTPAdapter. ([#​6716](https://github.com/psf/requests/issues/6716))
- Fixed issue where Requests started failing to run on Python versions compiled
without the `ssl` module. ([#​6724](https://github.com/psf/requests/issues/6724))
### [`v2.32.2`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2322-2024-05-21)
[Compare Source](https://github.com/psf/requests/compare/v2.32.1...v2.32.2)
**Deprecations**
- To provide a more stable migration for custom HTTPAdapters impacted
by the CVE changes in 2.32.0, we've renamed `_get_connection` to
a new public API, `get_connection_with_tls_context`. Existing custom
HTTPAdapters will need to migrate their code to use this new API.
`get_connection` is considered deprecated in all versions of Requests>=2.32.0.
A minimal (2-line) example has been provided in the linked PR to ease
migration, but we strongly urge users to evaluate if their custom adapter
is subject to the same issue described in CVE-2024-35195. ([#​6710](https://github.com/psf/requests/issues/6710))
### [`v2.32.1`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2321-2024-05-20)
[Compare Source](https://github.com/psf/requests/compare/v2.32.0...v2.32.1)

- Add missing test certs to the sdist distributed on PyPI.
### [`v2.32.0`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2320-2024-05-20)
[Compare Source](https://github.com/psf/requests/compare/v2.31.0...v2.32.0)
**Security**
- Fixed an issue where setting `verify=False` on the first request from a
Session will cause subsequent requests to the *same origin* to also ignore
cert verification, regardless of the value of `verify`.
(<https://github.com/psf/requests/security/advisories/GHSA-9wx4-h78v-vm56>)
**Improvements**
- `verify=True` now reuses a global SSLContext which should improve
request time variance between first and subsequent requests. It should
also minimize certificate load time on Windows systems when using a Python
version built with OpenSSL 3.x. ([#​6667](https://github.com/psf/requests/issues/6667))

will default to `utf-8` if neither library is present. ([#​6702](https://github.com/psf/requests/issues/6702))
**Bugfixes**
- Fixed bug in length detection where emoji length was incorrectly
calculated in the request content-length. ([#​6589](https://github.com/psf/requests/issues/6589))
- Fixed deserialization bug in JSONDecodeError. ([#​6629](https://github.com/psf/requests/issues/6629))
- Fixed bug where an extra leading `/` (path separator) could lead
urllib3 to unnecessarily reparse the request URI. ([#​6644](https://github.com/psf/requests/issues/6644))
**Deprecations**
- Requests has officially added support for CPython 3.12 ([#​6503](https://github.com/psf/requests/issues/6503))

### [`v2.30.0`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2300-2023-05-03)
[Compare Source](https://github.com/psf/requests/compare/v2.29.0...v2.30.0)
**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`.

[Compare Source](https://github.com/psf/requests/compare/v2.28.2...v2.29.0)
**Improvements**
- Requests now defers chunked requests to the urllib3 implementation to improve
standardization. ([#​6226](https://github.com/psf/requests/issues/6226))
- Requests relaxes header component requirements to support bytes/str subclasses. ([#​6356](https://github.com/psf/requests/issues/6356))
### [`v2.28.2`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2282-2023-01-12)
[Compare Source](https://github.com/psf/requests/compare/v2.28.1...v2.28.2)
**Dependencies**
- Requests now supports charset\_normalizer 3.x. ([#​6261](https://github.com/psf/requests/issues/6261))
**Bugfixes**

### [`v2.28.1`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2281-2022-06-29)
[Compare Source](https://github.com/psf/requests/compare/v2.28.0...v2.28.1)
**Improvements**
- Speed optimization in `iter_content` with transition to `yield from`. ([#​6170](https://github.com/psf/requests/issues/6170))
**Dependencies**
- Added support for chardet 5.0.0 ([#​6179](https://github.com/psf/requests/issues/6179))
- Added support for charset-normalizer 2.1.0 ([#​6169](https://github.com/psf/requests/issues/6169))

- ⚠️ Requests has officially dropped support for Python 2.7. ⚠️ ([#​6091](https://github.com/psf/requests/issues/6091))
- Requests has officially dropped support for Python 3.6 (including pypy3.6). ([#​6091](https://github.com/psf/requests/issues/6091))
**Improvements**
- Wrap JSON parsing issues in Request's JSONDecodeError for payloads without
an encoding to make `json()` API consistent. ([#​6097](https://github.com/psf/requests/issues/6097))
- Parse header components consistently, raising an InvalidHeader error in
all invalid cases. ([#​6154](https://github.com/psf/requests/issues/6154))
- Added provisional 3.11 support with current beta build. ([#​6155](https://github.com/psf/requests/issues/6155))
- Requests got a makeover and we decided to paint it black. ([#​6095](https://github.com/psf/requests/issues/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](https://github.com/psf/requests/issues/6074))
- Fixed urllib3 exception leak, wrapping `urllib3.exceptions.SSLError` with
`requests.exceptions.SSLError` for `content` and `iter_content`. ([#​6057](https://github.com/psf/requests/issues/6057))
- Fixed issue where invalid Windows registry entries caused proxy resolution
to raise an exception rather than ignoring the entry. ([#​6149](https://github.com/psf/requests/issues/6149))
- Fixed issue where entire payload could be included in the error message for
JSONDecodeError. ([#​6036](https://github.com/psf/requests/issues/6036))
### [`v2.27.1`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2271-2022-01-05)
[Compare Source](https://github.com/psf/requests/compare/v2.27.0...v2.27.1)
**Bugfixes**
- Fixed parsing issue that resulted in the `auth` component being
dropped from proxy URLs. ([#​6028](https://github.com/psf/requests/issues/6028))
### [`v2.27.0`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2270-2022-01-03)
[Compare Source](https://github.com/psf/requests/compare/v2.26.0...v2.27.0)
**Improvements**
- Officially added support for Python 3.10. ([#​5928](https://github.com/psf/requests/issues/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](https://github.com/psf/requests/issues/5856))
- Improved error text for misnamed `InvalidSchema` and `MissingSchema`
exceptions. This is a temporary fix until exceptions can be renamed
(Schema->Scheme). ([#​6017](https://github.com/psf/requests/issues/6017))
- Improved proxy parsing for proxy URLs missing a scheme. This will address
recent changes to `urlparse` in Python 3.9+. ([#​5917](https://github.com/psf/requests/issues/5917))
**Bugfixes**
- Fixed defect in `extract_zipped_paths` which could result in an infinite loop
for some paths. ([#​5851](https://github.com/psf/requests/issues/5851))
- Fixed handling for `AttributeError` when calculating length of files obtained
by `Tarfile.extractfile()`. ([#​5239](https://github.com/psf/requests/issues/5239))
- Fixed urllib3 exception leak, wrapping `urllib3.exceptions.InvalidHeader` with
`requests.exceptions.InvalidHeader`. ([#​5914](https://github.com/psf/requests/issues/5914))
- Fixed bug where two Host headers were sent for chunked requests. ([#​5391](https://github.com/psf/requests/issues/5391))
- Fixed regression in Requests 2.26.0 where `Proxy-Authorization` was
incorrectly stripped from all requests sent with `Session.send`. ([#​5924](https://github.com/psf/requests/issues/5924))
- Fixed performance regression in 2.26.0 for hosts with a large number of
proxies available in the environment. ([#​5924](https://github.com/psf/requests/issues/5924))
- Fixed idna exception leak, wrapping `UnicodeError` with
`requests.exceptions.InvalidURL` for URLs with a leading dot (.) in the
domain. ([#​5414](https://github.com/psf/requests/issues/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`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2260-2021-07-13)
[Compare Source](https://github.com/psf/requests/compare/v2.25.1...v2.26.0)
**Improvements**
- Requests now supports Brotli compression, if either the `brotli` or
`brotlicffi` package is installed. ([#​5783](https://github.com/psf/requests/issues/5783))
- `Session.send` now correctly resolves proxy configurations from both
the Session and Request. Behavior now matches `Session.request`. ([#​5681](https://github.com/psf/requests/issues/5681))
**Bugfixes**
- Fixed a race condition in zip extraction when using Requests in parallel
from zip archive. ([#​5707](https://github.com/psf/requests/issues/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](https://github.com/psf/requests/issues/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](https://github.com/psf/requests/issues/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](https://github.com/psf/requests/issues/5867))
- Requests has officially dropped support for Python 3.5. ([#​5867](https://github.com/psf/requests/issues/5867))
### [`v2.25.1`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2251-2020-12-16)
[Compare Source](https://github.com/psf/requests/compare/v2.25.0...v2.25.1)
**Bugfixes**
- Requests now treats `application/json` as `utf8` by default. Resolving
inconsistencies between `r.text` and `r.json` output. ([#​5673](https://github.com/psf/requests/issues/5673))
**Dependencies**
- Requests now supports chardet v4.x.
### [`v2.25.0`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2250-2020-11-11)
[Compare Source](https://github.com/psf/requests/compare/v2.24.0...v2.25.0)
**Improvements**
- Added support for NETRC environment variable. ([#​5643](https://github.com/psf/requests/issues/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`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2240-2020-06-17)
[Compare Source](https://github.com/psf/requests/compare/v2.23.0...v2.24.0)
**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](https://github.com/psf/requests/issues/5443))
- Redirect resolution should now only occur when
`allow_redirects` is True. ([#​5492](https://github.com/psf/requests/issues/5492))
- No longer perform unnecessary Content-Length calculation for
requests that won't use it. ([#​5496](https://github.com/psf/requests/issues/5496))
### [`v2.23.0`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2230-2020-02-19)
[Compare Source](https://github.com/psf/requests/compare/v2.22.0...v2.23.0)
**Improvements**
- Remove defunct reference to `prefetch` in Session `__attrs__` ([#​5110](https://github.com/psf/requests/issues/5110))
**Bugfixes**
- Requests no longer outputs password in basic auth usage warning. ([#​5099](https://github.com/psf/requests/issues/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`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2220-2019-05-15)
[Compare Source](https://github.com/psf/requests/compare/v2.21.0...v2.22.0)

redirects using default ports (http/80, https/443).
### [`v2.20.0`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2200-2018-10-18)
[Compare Source](https://github.com/psf/requests/compare/v2.19.1...v2.20.0)
**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**

### [`v2.19.1`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2191-2018-06-14)
[Compare Source](https://github.com/psf/requests/compare/v2.19.0...v2.19.1)
**Bugfixes**
- Fixed issue where status\_codes.py's `init` function failed trying
to append to a `__doc__` value of `None`.
### [`v2.19.0`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2190-2018-06-12)
[Compare Source](https://github.com/psf/requests/compare/v2.18.4...v2.19.0)
**Improvements**
- Warn user about possible slowdown when using cryptography version
< 1.3.4
- Check for invalid host in proxy URL, before forwarding request to
adapter.
- Fragments are now properly maintained across redirects. (RFC7231
7.1.2)
- Removed use of cgi module to expedite library load time.
- Added support for SHA-256 and SHA-512 digest auth algorithms.
- Minor performance improvement to `Request.content`.
- Migrate to using collections.abc for 3.7 compatibility.
**Bugfixes**

password in the request. This also fixes the issue of DNS queries
failing on macOS.
- Properly normalize adapter prefixes for url comparison.
- Passing `None` as a file pointer to the `files` param no longer
raises an exception.
- Calling `copy` on a `RequestsCookieJar` will now preserve the cookie

**Improvements**
- Running `$ python -m requests.help` now includes the installed
version of idna.
**Bugfixes**
- Fixed issue where Requests would raise `ConnectionError` instead of
`SSLError` when encountering SSL problems when using urllib3 v1.22.
### [`v2.18.2`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2182-2017-07-25)
[Compare Source](https://github.com/psf/requests/compare/v2.18.1...v2.18.2)

incorrect data that regressed the fix in v2.17.3.
### [`v2.18.0`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2180-2017-06-14)
[Compare Source](https://github.com/psf/requests/compare/v2.17.3...v2.18.0)
**Improvements**

`with` statement without first having to be wrapped by
`contextlib.closing()`.
**Bugfixes**
- Resolve installation failure if multiprocessing is not available
- Resolve tests crash if multiprocessing is not able to determine the
number of CPU cores
- Resolve error swallowing in utils set\_environ generator
### [`v2.17.3`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2173-2017-05-29)

[Compare Source](https://github.com/psf/requests/compare/v2.16.5...v2.17.0)
**Improvements**
- Removal of the 301 redirect cache. This improves thread-safety.
### [`v2.16.5`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2165-2017-05-28)
[Compare Source](https://github.com/psf/requests/compare/v2.16.4...v2.16.5)
- Improvements to `$ python -m requests.help`.
### [`v2.16.4`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2164-2017-05-27)
[Compare Source](https://github.com/psf/requests/compare/v2.16.3...v2.16.4)
- Introduction of the `$ python -m requests.help` command, for
debugging with maintainers!
### [`v2.16.3`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2163-2017-05-27)
[Compare Source](https://github.com/psf/requests/compare/v2.16.2...v2.16.3)
- Further restored the `requests.packages` namespace for compatibility

### [`v2.16.1`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2161-2017-05-27)
[Compare Source](https://github.com/psf/requests/compare/v2.16.0...v2.16.1)
- Restored the `requests.packages` namespace for compatibility
reasons.
- Bugfix for `urllib3` version parsing.
**Note**: code that was written to import against the
`requests.packages` namespace previously will have to import code that
rests at this module-level now.
For example:
```
from requests.packages.urllib3.poolmanager import PoolManager
```
Will need to be re-written to be:
```
from requests.packages import urllib3
urllib3.poolmanager.PoolManager
```
Or, even better:
```
from urllib3.poolmanager import PoolManager
```

**Improvements**
- Introduction of the `Response.next` property, for getting the next
`PreparedResponse` from a redirect chain (when
`allow_redirects=False`).
- Internal refactoring of `__version__` module.
**Bugfixes**
- Restored once-optional parameter for
`requests.utils.get_environ_proxies()`.
### [`v2.14.2`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2142-2017-05-10)
[Compare Source](https://github.com/psf/requests/compare/v2.14.1...v2.14.2)
**Bugfixes**
- Changed a less-than to an equal-to and an or in the dependency
markers to widen compatibility with older setuptools releases.
### [`v2.14.1`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2141-2017-05-09)
[Compare Source](https://github.com/psf/requests/compare/v2.14.0...v2.14.1)
**Bugfixes**
- Changed the dependency markers to widen compatibility with older pip
releases.
### [`v2.14.0`](https://github.com/psf/requests/blob/HEAD/HISTORY.md#2140-2017-05-09)
[Compare Source](https://github.com/psf/requests/compare/v2.13.0...v2.14.0)
**Improvements**
- It is now possible to pass `no_proxy` as a key to the `proxies`
dictionary to provide handling similar to the `NO_PROXY` environment
variable.
- When users provide invalid paths to certificate bundle files or
directories Requests now raises `IOError`, rather than failing at
the time of the HTTPS request with a fairly inscrutable certificate
validation error.
- The behavior of `SessionRedirectMixin` was slightly altered.
`resolve_redirects` will now detect a redirect by calling
`get_redirect_target(response)` instead of directly querying
`Response.is_redirect` and `Response.headers['location']`. Advanced
users will be able to process malformed redirects more easily.
- Changed the internal calculation of elapsed request time to have
higher resolution on Windows.
- Added `win_inet_pton` as conditional dependency for the `[socks]`
extra on Windows with Python 2.7.
- Changed the proxy bypass implementation on Windows: the proxy bypass
check doesn't use forward and reverse DNS requests anymore
- URLs with schemes that begin with `http` but are not `http` or
`https` no longer have their host parts forced to lowercase.
**Bugfixes**
- Much improved handling of non-ASCII `Location` header values in
redirects. Fewer `UnicodeDecodeErrors` are encountered on Python 2,
and Python 3 now correctly understands that Latin-1 is unlikely to
be the correct encoding.
- If an attempt to `seek` file to find out its length fails, we now
appropriately handle that by aborting our content-length
calculations.
- Restricted `HTTPDigestAuth` to only respond to auth challenges made
on 4XX responses, rather than to all auth challenges.
- Fixed some code that was firing `DeprecationWarning` on Python 3.6.
- The dismayed person emoticon (`/o\\`) no longer has a big head. I'm
sure this is what you were all worrying about most.
**Miscellaneous**
- Updated bundled urllib3 to v1.21.1.
- Updated bundled chardet to v3.0.2.
- Updated bundled idna to v2.5.
- Updated bundled certifi to 2017.4.17.

To provide a more stable migration for custom HTTPAdapters impacted
by the CVE changes in 2.32.0, we've renamed
_get_connectiontoa new public API,
get_connection_with_tls_context. Existing customHTTPAdapters will need to migrate their code to use this new API.
get_connectionis considered deprecated in all versions of Requests>=2.32.0.A minimal (2-line) example has been provided in the linked PR to ease
migration, but we strongly urge users to evaluate if their custom adapter
is subject to the same issue described in CVE-2024-35195. (#6710)

v2.31.0Compare Source
Security
Versions of Requests between v2.3.0 and v2.30.0 are vulnerable to potential
forwarding of
Proxy-Authorizationheaders to destination servers whenfollowing HTTPS redirects.
When proxies are defined with user info (
https://user:pass@proxy:8080), Requestswill construct a
Proxy-Authorizationheader that is attached to the request toauthenticate with the proxy.
In cases where Requests receives a redirect response, it previously reattached
the
Proxy-Authorizationheader incorrectly, resulting in the value beingsent 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.
