libraries.
```
### 2.17.1
```
-------------------
**Improvements**
- Improved `packages` namespace identity support, for monkeypatching
libraries.
```

reasons.
```
### 2.16.2
```
-------------------
- Further restored the `requests.packages` namespace for compatibility
reasons.
No code modification (noted below) should be necessary any longer.
```
### 2.16.1
```
-------------------
- 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
```
### 2.16.0
```
-------------------
- Unvendor ALL the things!
```
### 2.15.1
```
-------------------
- Everyone makes mistakes.
```
### 2.15.0
```
-------------------
**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
```
-------------------
**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
```
-------------------
**Bugfixes**
- Changed the dependency markers to widen compatibility with older pip
releases.
```
### 2.14.0
```
-------------------
**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.
```
### 2.13.0
```
-------------------
**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
```
-------------------
**Bugfixes**
- Fixed an issue with JSON encoding detection, specifically detecting
big-endian UTF-32 with BOM.
```
### 2.12.4
```
-------------------
**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
readded, the behaviour is deprecated and will be removed in the
future.
```
### 2.12.3
```
-------------------
**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
```
-------------------
**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
```
-------------------
**Bugfixes**
- Updated setuptools 'security' extra for the new PyOpenSSL backend in
urllib3.
**Miscellaneous**
- Updated bundled urllib3 to 1.19.1.
```
### 2.12.0
```
-------------------
**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
```
-------------------
**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
```
-------------------
**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
```
-------------------
**New Features**
- SOCKS Proxy Support! (requires PySocks;
`$ pip install requests[socks]`)
**Miscellaneous**
- Updated bundled urllib3 to 1.15.1.
```
### 2.9.2
```
------------------
**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
```
------------------
**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
```
------------------
**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 seeked 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
```
------------------
**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
```
------------------
**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
```
------------------
This is the first release that follows our new release process. For
more, see [our
documentation](http://docs.python-requests.org/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
```
------------------
**Bugfixes**
- Fix regression where compressed data that was sent as chunked data
was not properly decompressed. (\2561)
```
### 2.6.1
```
------------------
**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)

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 ``` ------------------- **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 ``` ------------------- **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 ``` ------------------- **New Features** - SOCKS Proxy Support! (requires PySocks; `$ pip install requests[socks]`) **Miscellaneous** - Updated bundled urllib3 to 1.15.1. ``` ### 2.9.2 ``` ------------------ **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 ``` ------------------ **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 ``` ------------------ **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 seeked 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 ``` ------------------ **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 ``` ------------------ **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 ``` ------------------ This is the first release that follows our new release process. For more, see [our documentation](http://docs.python-requests.org/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 ``` ------------------ **Bugfixes** - Fix regression where compressed data that was sent as chunked data was not properly decompressed. (\2561) ``` ### 2.6.1 ``` ------------------ **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) ```Links
