- \[Short description of non-trivial change.\]

2.32.3 (2024-05-29)
-------------------

**Bugfixes**
- Fixed bug breaking the ability to specify custom SSLContexts in sub-classes of
  HTTPAdapter. (#6716)
- Fixed issue where Requests started failing to run on Python versions compiled
  without the `ssl` module. (#6724)

2.32.2 (2024-05-21)
-------------------

**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)

2.32.1 (2024-05-20)
-------------------

**Bugfixes**
- Add missing test certs to the sdist distributed on PyPI.

2.32.0 (2024-05-20)
-------------------

**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)
- 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.

2.31.0 (2023-05-22)
-------------------

**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](https://github.com/psf/requests/security/advisories/GHSA-j8r2-6x86-q33q)
  and [CVE-2023-32681](https://nvd.nist.gov/vuln/detail/CVE-2023-32681).

2.30.0 (2023-05-03)
-------------------

**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`.

2.29.0 (2023-04-26)
-------------------

**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)

2.28.2 (2023-01-12)
-------------------

**Dependencies**

- Requests now supports charset\_normalizer 3.x. (#6261)

**Bugfixes**

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

2.28.1 (2022-06-29)
-------------------

**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)

2.28.0 (2022-06-09)
-------------------

**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)

2.27.1 (2022-01-05)
-------------------

**Bugfixes**

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

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.

2.26.0 (2021-07-13)
-------------------

**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)

2.25.1 (2020-12-16)
-------------------

**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.

2.25.0 (2020-11-11)
-------------------

**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.

2.24.0 (2020-06-17)
-------------------

**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)

2.23.0 (2020-02-19)
-------------------

**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.

2.22.0 (2019-05-15)
-------------------

**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.

2.21.0 (2018-12-10)
-------------------

**Dependencies**

- Requests now supports idna v2.8.

2.20.1 (2018-11-08)
-------------------

**Bugfixes**

- Fixed bug with unintended Authorization header stripping for
  redirects using default ports (http/80, https/443).

2.20.0 (2018-10-18)
-------------------

**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.

2.19.1 (2018-06-14)
-------------------

**Bugfixes**

-   Fixed issue where status\_codes.py's `init` function failed trying
    to append to a `__doc__` value of `None`.

2.19.0 (2018-06-12)
-------------------

**Improvements**

-   Warn user about possible slowdown when using cryptography version
    &lt; 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**

-   Parsing empty `Link` headers with `parse_header_links()` no longer
    return one bogus entry.
-   Fixed issue where loading the default certificate bundle from a zip
    archive would raise an `IOError`.
-   Fixed issue with unexpected `ImportError` on windows system which do
    not support `winreg` module.
-   DNS resolution in proxy bypass no longer includes the username and
    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
    policy correctly.

**Dependencies**

-   We now support idna v2.7.
-   We now support urllib3 v1.23.

2.18.4 (2017-08-15)
-------------------

**Improvements**

-   Error messages for invalid headers now include the header name for
    easier debugging

**Dependencies**

-   We now support idna v2.6.

2.18.3 (2017-08-02)
-------------------

**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.

2.18.2 (2017-07-25)
-------------------

**Bugfixes**

-   `requests.help` no longer fails on Python 2.6 due to the absence of
    `ssl.OPENSSL_VERSION_NUMBER`.

**Dependencies**

-   We now support urllib3 v1.22.

2.18.1 (2017-06-14)
-------------------

**Bugfixes**

-   Fix an error in the packaging whereby the `*.whl` contained
    incorrect data that regressed the fix in v2.17.3.

2.18.0 (2017-06-14)
-------------------

**Improvements**

-   `Response` is now a context manager, so can be used directly in a
    `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

2.17.3 (2017-05-29)
-------------------

**Improvements**

-   Improved `packages` namespace identity support, for monkeypatching
    libraries.

2.17.2 (2017-05-29)
-------------------

**Improvements**

-   Improved `packages` namespace identity support, for monkeypatching
    libraries.

2.17.1 (2017-05-29)
-------------------

**Improvements**

-   Improved `packages` namespace identity support, for monkeypatching
    libraries.

2.17.0 (2017-05-29)
-------------------

**Improvements**

-   Removal of the 301 redirect cache. This improves thread-safety.

2.16.5 (2017-05-28)
-------------------

-   Improvements to `$ python -m requests.help`.

2.16.4 (2017-05-27)
-------------------

-   Introduction of the `$ python -m requests.help` command, for
    debugging with maintainers!

2.16.3 (2017-05-27)
-------------------

-   Further restored the `requests.packages` namespace for compatibility
    reasons.

2.16.2 (2017-05-27)
-------------------

-   Further restored the `requests.packages` namespace for compatibility
    reasons.

No code modification (noted below) should be necessary any longer.

2.16.1 (2017-05-27)
-------------------

-   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

2.16.0 (2017-05-26)
-------------------

-   Unvendor ALL the things!

2.15.1 (2017-05-26)
-------------------

-   Everyone makes mistakes.

2.15.0 (2017-05-26)
-------------------

**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()`.

2.14.2 (2017-05-10)
-------------------

**Bugfixes**

-   Changed a less-than to an equal-to and an or in the dependency
    markers to widen compatibility with older setuptools releases.

2.14.1 (2017-05-09)
-------------------

**Bugfixes**

-   Changed the dependency markers to widen compatibility with older pip
    releases.

2.14.0 (2017-05-09)
-------------------

**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.

2.13.0 (2017-01-24)
-------------------

**Features**

-   Only load the `idna` library when we've determined we need it. This
    will save some memory for users.

**Miscellaneous**

-   Updated bundled urllib3 to 1.20.
-   Updated bundled idna to 2.2.

2.12.5 (2017-01-18)
-------------------

**Bugfixes**

-   Fixed an issue with JSON encoding detection, specifically detecting
    big-endian UTF-32 with BOM.

2.12.4 (2016-12-14)
-------------------

**Bugfixes**

-   Fixed regression from 2.12.2 where non-string types were rejected in
    the basic auth parameters. While support for this behaviour has been
    re-added, the behaviour is deprecated and will be removed in the
    future.

2.12.3 (2016-12-01)
-------------------

**Bugfixes**

-   Fixed regression from v2.12.1 for URLs with schemes that begin with
    "http". These URLs have historically been processed as though they
    were HTTP-schemed URLs, and so have had parameters added. This was
    removed in v2.12.2 in an overzealous attempt to resolve problems
    with IDNA-encoding those URLs. This change was reverted: the other
    fixes for IDNA-encoding have been judged to be sufficient to return
    to the behaviour Requests had before v2.12.0.

2.12.2 (2016-11-30)
-------------------

**Bugfixes**

-   Fixed several issues with IDNA-encoding URLs that are technically
    invalid but which are widely accepted. Requests will now attempt to
    IDNA-encode a URL if it can but, if it fails, and the host contains
    only ASCII characters, it will be passed through optimistically.
    This will allow users to opt-in to using IDNA2003 themselves if they
    want to, and will also allow technically invalid but still common
    hostnames.
-   Fixed an issue where URLs with leading whitespace would raise
    `InvalidSchema` errors.
-   Fixed an issue where some URLs without the HTTP or HTTPS schemes
    would still have HTTP URL preparation applied to them.
-   Fixed an issue where Unicode strings could not be used in basic
    auth.
-   Fixed an issue encountered by some Requests plugins where
    constructing a Response object would cause `Response.content` to
    raise an `AttributeError`.

2.12.1 (2016-11-16)
-------------------

**Bugfixes**

-   Updated setuptools 'security' extra for the new PyOpenSSL backend in
    urllib3.

**Miscellaneous**

-   Updated bundled urllib3 to 1.19.1.

2.12.0 (2016-11-15)
-------------------

**Improvements**

-   Updated support for internationalized domain names from IDNA2003 to
    IDNA2008. This updated support is required for several forms of IDNs
    and is mandatory for .de domains.
-   Much improved heuristics for guessing content lengths: Requests will
    no longer read an entire `StringIO` into memory.
-   Much improved logic for recalculating `Content-Length` headers for
    `PreparedRequest` objects.
-   Improved tolerance for file-like objects that have no `tell` method
    but do have a `seek` method.
-   Anything that is a subclass of `Mapping` is now treated like a
    dictionary by the `data=` keyword argument.
-   Requests now tolerates empty passwords in proxy credentials, rather
    than stripping the credentials.
-   If a request is made with a file-like object as the body and that
    request is redirected with a 307 or 308 status code, Requests will
    now attempt to rewind the body object so it can be replayed.

**Bugfixes**

-   When calling `response.close`, the call to `close` will be
    propagated through to non-urllib3 backends.
-   Fixed issue where the `ALL_PROXY` environment variable would be
    preferred over scheme-specific variables like `HTTP_PROXY`.
-   Fixed issue where non-UTF8 reason phrases got severely mangled by
    falling back to decoding using ISO 8859-1 instead.
-   Fixed a bug where Requests would not correctly correlate cookies set
    when using custom Host headers if those Host headers did not use the
    native string type for the platform.

**Miscellaneous**

-   Updated bundled urllib3 to 1.19.
-   Updated bundled certifi certs to 2016.09.26.

2.11.1 (2016-08-17)
-------------------

**Bugfixes**

-   Fixed a bug when using `iter_content` with `decode_unicode=True` for
    streamed bodies would raise `AttributeError`. This bug was
    introduced in 2.11.
-   Strip Content-Type and Transfer-Encoding headers from the header
    block when following a redirect that transforms the verb from
    POST/PUT to GET.

2.11.0 (2016-08-08)
-------------------

**Improvements**

-   Added support for the `ALL_PROXY` environment variable.
-   Reject header values that contain leading whitespace or newline
    characters to reduce risk of header smuggling.

**Bugfixes**

-   Fixed occasional `TypeError` when attempting to decode a JSON
    response that occurred in an error case. Now correctly returns a
    `ValueError`.
-   Requests would incorrectly ignore a non-CIDR IP address in the
    `NO_PROXY` environment variables: Requests now treats it as a
    specific IP.
-   Fixed a bug when sending JSON data that could cause us to encounter
    obscure OpenSSL errors in certain network conditions (yes, really).
-   Added type checks to ensure that `iter_content` only accepts
    integers and `None` for chunk sizes.
-   Fixed issue where responses whose body had not been fully consumed
    would have the underlying connection closed but not returned to the
    connection pool, which could cause Requests to hang in situations
    where the `HTTPAdapter` had been configured to use a blocking
    connection pool.

**Miscellaneous**

-   Updated bundled urllib3 to 1.16.
-   Some previous releases accidentally accepted non-strings as
    acceptable header values. This release does not.

2.10.0 (2016-04-29)
-------------------

**New Features**

-   SOCKS Proxy Support! (requires PySocks;
    `$ pip install requests[socks]`)

**Miscellaneous**

-   Updated bundled urllib3 to 1.15.1.

2.9.2 (2016-04-29)
------------------

**Improvements**

-   Change built-in CaseInsensitiveDict (used for headers) to use
    OrderedDict as its underlying datastore.

**Bugfixes**

-   Don't use redirect\_cache if allow\_redirects=False
-   When passed objects that throw exceptions from `tell()`, send them
    via chunked transfer encoding instead of failing.
-   Raise a ProxyError for proxy related connection issues.

2.9.1 (2015-12-21)
------------------

**Bugfixes**

-   Resolve regression introduced in 2.9.0 that made it impossible to
    send binary strings as bodies in Python 3.
-   Fixed errors when calculating cookie expiration dates in certain
    locales.

**Miscellaneous**

-   Updated bundled urllib3 to 1.13.1.

2.9.0 (2015-12-15)
------------------

**Minor Improvements** (Backwards compatible)

-   The `verify` keyword argument now supports being passed a path to a
    directory of CA certificates, not just a single-file bundle.
-   Warnings are now emitted when sending files opened in text mode.
-   Added the 511 Network Authentication Required status code to the
    status code registry.

**Bugfixes**

-   For file-like objects that are not sought to the very beginning, we
    now send the content length for the number of bytes we will actually
    read, rather than the total size of the file, allowing partial file
    uploads.
-   When uploading file-like objects, if they are empty or have no
    obvious content length we set `Transfer-Encoding: chunked` rather
    than `Content-Length: 0`.
-   We correctly receive the response in buffered mode when uploading
    chunked bodies.
-   We now handle being passed a query string as a bytestring on Python
    3, by decoding it as UTF-8.
-   Sessions are now closed in all cases (exceptional and not) when
    using the functional API rather than leaking and waiting for the
    garbage collector to clean them up.
-   Correctly handle digest auth headers with a malformed `qop`
    directive that contains no token, by treating it the same as if no
    `qop` directive was provided at all.
-   Minor performance improvements when removing specific cookies by
    name.

**Miscellaneous**

-   Updated urllib3 to 1.13.

2.8.1 (2015-10-13)
------------------

**Bugfixes**

-   Update certificate bundle to match `certifi` 2015.9.6.2's weak
    certificate bundle.
-   Fix a bug in 2.8.0 where requests would raise `ConnectTimeout`
    instead of `ConnectionError`
-   When using the PreparedRequest flow, requests will now correctly
    respect the `json` parameter. Broken in 2.8.0.
-   When using the PreparedRequest flow, requests will now correctly
    handle a Unicode-string method name on Python 2. Broken in 2.8.0.

2.8.0 (2015-10-05)
------------------

**Minor Improvements** (Backwards Compatible)

-   Requests now supports per-host proxies. This allows the `proxies`
    dictionary to have entries of the form
    `{'<scheme>://<hostname>': '<proxy>'}`. Host-specific proxies will
    be used in preference to the previously-supported scheme-specific
    ones, but the previous syntax will continue to work.
-   `Response.raise_for_status` now prints the URL that failed as part
    of the exception message.
-   `requests.utils.get_netrc_auth` now takes an `raise_errors` kwarg,
    defaulting to `False`. When `True`, errors parsing `.netrc` files
    cause exceptions to be thrown.
-   Change to bundled projects import logic to make it easier to
    unbundle requests downstream.
-   Changed the default User-Agent string to avoid leaking data on
    Linux: now contains only the requests version.

**Bugfixes**

-   The `json` parameter to `post()` and friends will now only be used
    if neither `data` nor `files` are present, consistent with the
    documentation.
-   We now ignore empty fields in the `NO_PROXY` environment variable.
-   Fixed problem where `httplib.BadStatusLine` would get raised if
    combining `stream=True` with `contextlib.closing`.
-   Prevented bugs where we would attempt to return the same connection
    back to the connection pool twice when sending a Chunked body.
-   Miscellaneous minor internal changes.
-   Digest Auth support is now thread safe.

**Updates**

-   Updated urllib3 to 1.12.

2.7.0 (2015-05-03)
------------------

This is the first release that follows our new release process. For
more, see [our
documentation](https://requests.readthedocs.io/en/latest/community/release-process/).

**Bugfixes**

-   Updated urllib3 to 1.10.4, resolving several bugs involving chunked
    transfer encoding and response framing.

2.6.2 (2015-04-23)
------------------

**Bugfixes**

-   Fix regression where compressed data that was sent as chunked data
    was not properly decompressed. (\#2561)

2.6.1 (2015-04-22)
------------------

**Bugfixes**

-   Remove VendorAlias import machinery introduced in v2.5.2.
-   Simplify the PreparedRequest.prepare API: We no longer require the
    user to pass an empty list to the hooks keyword argument. (c.f.
    \#2552)
-   Resolve redirects now receives and forwards all of the original
    arguments to the adapter. (\#2503)
-   Handle UnicodeDecodeErrors when trying to deal with a unicode URL
    that cannot be encoded in ASCII. (\#2540)
-   Populate the parsed path of the URI field when performing Digest
    Authentication. (\#2426)
-   Copy a PreparedRequest's CookieJar more reliably when it is not an
    instance of RequestsCookieJar. (\#2527)

2.6.0 (2015-03-14)
------------------

**Bugfixes**

-   CVE-2015-2296: Fix handling of cookies on redirect. Previously a
    cookie without a host value set would use the hostname for the
    redirected URL exposing requests users to session fixation attacks
    and potentially cookie stealing. This was disclosed privately by
    Matthew Daley of [BugFuzz](https://bugfuzz.com). This affects all
    versions of requests from v2.1.0 to v2.5.3 (inclusive on both ends).
-   Fix error when requests is an `install_requires` dependency and
    `python setup.py test` is run. (\#2462)
-   Fix error when urllib3 is unbundled and requests continues to use
    the vendored import location.
-   Include fixes to `urllib3`'s header handling.
-   Requests' handling of unvendored dependencies is now more
    restrictive.

**Features and Improvements**

-   Support bytearrays when passed as parameters in the `files`
    argument. (\#2468)
-   Avoid data duplication when creating a request with `str`, `bytes`,
    or `bytearray` input to the `files` argument.

2.5.3 (2015-02-24)
------------------

**Bugfixes**

-   Revert changes to our vendored certificate bundle. For more context
    see (\#2455, \#2456, and <https://bugs.python.org/issue23476>)

2.5.2 (2015-02-23)
------------------

**Features and Improvements**

-   Add sha256 fingerprint support.
    ([shazow/urllib3\#540](https://github.com/shazow/urllib3/pull/540))
-   Improve the performance of headers.
    ([shazow/urllib3\#544](https://github.com/shazow/urllib3/pull/544))

**Bugfixes**

-   Copy pip's import machinery. When downstream redistributors remove
    requests.packages.urllib3 the import machinery will continue to let
    those same symbols work. Example usage in requests' documentation
    and 3rd-party libraries relying on the vendored copies of urllib3
    will work without having to fallback to the system urllib3.
-   Attempt to quote parts of the URL on redirect if unquoting and then
    quoting fails. (\#2356)
-   Fix filename type check for multipart form-data uploads. (\#2411)
-   Properly handle the case where a server issuing digest
    authentication challenges provides both auth and auth-int
    qop-values. (\#2408)
-   Fix a socket leak.
    ([shazow/urllib3\#549](https://github.com/shazow/urllib3/pull/549))
-   Fix multiple `Set-Cookie` headers properly.
    ([shazow/urllib3\#534](https://github.com/shazow/urllib3/pull/534))
-   Disable the built-in hostname verification.
    ([shazow/urllib3\#526](https://github.com/shazow/urllib3/pull/526))
-   Fix the behaviour of decoding an exhausted stream.
    ([shazow/urllib3\#535](https://github.com/shazow/urllib3/pull/535))

**Security**

-   Pulled in an updated `cacert.pem`.
-   Drop RC4 from the default cipher list.
    ([shazow/urllib3\#551](https://github.com/shazow/urllib3/pull/551))

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

**Improvements**

-   Allow usage of urllib3's Retry object with HTTPAdapters (\#2216)
-   The `iter_lines` method on a response now accepts a delimiter with
    which to split the content (\#2295)

    ([\#2249](https://github.com/psf/requests/issues/2249))

2.4.2 (2014-10-05)
------------------

**Improvements**

-   FINALLY! Add json parameter for uploads!
    ([\#2258](https://github.com/psf/requests/pull/2258))

-   Added example of how to send multiple files in one request.
    ([\#2227](https://github.com/psf/requests/pull/2227/))
-   Clarify how to pass a custom set of CAs
    ([\#2248](https://github.com/psf/requests/pull/2248/))

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

**Behavioral Changes**

-   `Connection: keep-alive` header is now sent automatically.

    read) which is used to set individual connect and read timeouts.
-   Allow copying of PreparedRequests without headers/cookies.
-   Updated bundled urllib3 version.
-   Refactored settings loading from environment -- new
    Session.merge\_environment\_settings.
-   Handle socket errors in iter\_content.

2.3.0 (2014-05-16)
------------------

**API Changes**

-   New `Response` property `is_redirect`, which is true when the
    library could have processed this response as a redirection (whether
    or not it actually did).
-   The `timeout` parameter now affects requests with both `stream=True`
    and `stream=False` equally.
-   The change in v2.0.0 to mandate explicit proxy schemes has been
    reverted. Proxy schemes now default to `http://`.
-   The `CaseInsensitiveDict` used for HTTP headers now behaves like a
    normal dictionary when references as string or viewed in the
    interpreter.

**Bugfixes**

-   No longer expose Authorization or Proxy-Authorization headers on
    redirect. Fix CVE-2014-1829 and CVE-2014-1830 respectively.
-   Authorization is re-evaluated each redirect.
-   On redirect, pass url as native strings.
-   Fall-back to autodetected encoding for JSON when Unicode detection

-   The `Response.history` parameter is now always a list.
-   Many, many `urllib3` bugfixes.

2.2.1 (2014-01-23)
------------------

**Bugfixes**

-   Fixes incorrect parsing of proxy credentials that contain a literal
    or encoded '\#' character.
-   Assorted urllib3 fixes.

2.2.0 (2014-01-09)
------------------

**API Changes**

-   New exception: `ContentDecodingError`. Raised instead of `urllib3`
    `DecodeError` exceptions.

**Bugfixes**

-   Avoid many many exceptions from the buggy implementation of
    `proxy_bypass` on OS X in Python 2.6.
-   Avoid crashing when attempting to get authentication credentials
    from \~/.netrc when running as a user without a home directory.
-   Use the correct pool size for pools of connections to proxies.
-   Fix iteration of `CookieJar` objects.
-   Ensure that cookies are persisted over redirect.
-   Switch back to using chardet, since it has merged with charade.

2.1.0 (2013-12-05)
------------------

-   Updated CA Bundle, of course.
-   Cookies set on individual Requests through a `Session` (e.g. via
    `Session.get()`) are no longer persisted to the `Session`.
-   Clean up connections when we hit problems during chunked upload,
    rather than leaking them.
-   Return connections to the pool when a chunked upload is successful,
    rather than leaking it.
-   Match the HTTPbis recommendation for HTTP 301 redirects.
-   Prevent hanging when using streaming uploads and Digest Auth when a
    401 is received.
-   Values of headers set by Requests are now always the native string
    type.
-   Fix previously broken SNI support.
-   Fix accessing HTTP proxies using proxy authentication.
-   Unencode HTTP Basic usernames and passwords extracted from URLs.
-   Support for IP address ranges for no\_proxy environment variable
-   Parse headers correctly when users override the default `Host:`
    header.
-   Avoid munging the URL in case of case-sensitive servers.
-   Looser URL handling for non-HTTP/HTTPS urls.
-   Accept unicode methods in Python 2.6 and 2.7.
-   More resilient cookie handling.
-   Make `Response` objects pickleable.
-   Actually added MD5-sess to Digest Auth instead of pretending to like
    last time.
-   Updated internal urllib3.
-   Fixed @Lukasa's lack of taste.

2.0.1 (2013-10-24)
------------------

-   Updated included CA Bundle with new mistrusts and automated process
    for the future
-   Added MD5-sess to Digest Auth
-   Accept per-file headers in multipart file POST messages.
-   Fixed: Don't send the full URL on CONNECT messages.
-   Fixed: Correctly lowercase a redirect scheme.
-   Fixed: Cookies not persisted when set via functional API.
-   Fixed: Translate urllib3 ProxyError into a requests ProxyError
    derived from ConnectionError.
-   Updated internal urllib3 and chardet.

2.0.0 (2013-09-24)
------------------

**API Changes:**

-   Keys in the Headers dictionary are now native strings on all Python
    versions, i.e. bytestrings on Python 2, unicode on Python 3.
-   Proxy URLs now *must* have an explicit scheme. A `MissingSchema`
    exception will be raised if they don't.
-   Timeouts now apply to read time if `Stream=False`.
-   `RequestException` is now a subclass of `IOError`, not
    `RuntimeError`.
-   Added new method to `PreparedRequest` objects:
    `PreparedRequest.copy()`.
-   Added new method to `Session` objects: `Session.update_request()`.
    This method updates a `Request` object with the data (e.g. cookies)
    stored on the `Session`.
-   Added new method to `Session` objects: `Session.prepare_request()`.
    This method updates and prepares a `Request` object, and returns the
    corresponding `PreparedRequest` object.
-   Added new method to `HTTPAdapter` objects:
    `HTTPAdapter.proxy_headers()`. This should not be called directly,
    but improves the subclass interface.
-   `httplib.IncompleteRead` exceptions caused by incorrect chunked
    encoding will now raise a Requests `ChunkedEncodingError` instead.
-   Invalid percent-escape sequences now cause a Requests `InvalidURL`
    exception to be raised.
-   HTTP 208 no longer uses reason phrase `"im_used"`. Correctly uses
    `"already_reported"`.
-   HTTP 226 reason added (`"im_used"`).

**Bugfixes:**

-   Vastly improved proxy support, including the CONNECT verb. Special
    thanks to the many contributors who worked towards this improvement.
-   Cookies are now properly managed when 401 authentication responses
    are received.
-   Chunked encoding fixes.
-   Support for mixed case schemes.
-   Better handling of streaming downloads.
-   Retrieve environment proxies from more locations.
-   Minor cookies fixes.
-   Improved redirect behaviour.
-   Improved streaming behaviour, particularly for compressed data.
-   Miscellaneous small Python 3 text encoding bugs.
-   `.netrc` no longer overrides explicit auth.
-   Cookies set by hooks are now correctly persisted on Sessions.
-   Fix problem with cookies that specify port numbers in their host
    field.
-   `BytesIO` can be used to perform streaming uploads.
-   More generous parsing of the `no_proxy` environment variable.
-   Non-string objects can be passed in data values alongside files.

-   Fix connection adapter matching to be most-specific first
-   new argument to the default connection adapter for passing a block
    argument
-   prevent a KeyError when there's no link headers

1.2.0 (2013-03-31)
------------------

-   Fixed cookies on sessions and on requests
-   Significantly change how hooks are dispatched - hooks now receive
    all the arguments specified by the user when making a request so
    hooks can make a secondary request with the same parameters. This is
    especially necessary for authentication handler authors
-   certifi support was removed
-   Fixed bug where using OAuth 1 with body `signature_type` sent no
    data
-   Major proxy work thanks to @Lukasa including parsing of proxy
    authentication from the proxy url
-   Fix DigestAuth handling too many 401s
-   Update vendored urllib3 to include SSL bug fixes
-   Allow keyword arguments to be passed to `json.loads()` via the
    `Response.json()` method
-   Don't send `Content-Length` header by default on `GET` or `HEAD`
    requests
-   Add `elapsed` attribute to `Response` objects to time how long a
    request took.
-   Fix `RequestsCookieJar`
-   Sessions and Adapters are now picklable, i.e., can be used with the
    multiprocessing library
-   Update charade to version 1.0.3

The change in how hooks are dispatched will likely cause a great deal of
issues.
