libraries.
### [`v2.17.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2170-2017-05-29)
[Compare Source](https://togithub.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://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2165-2017-05-28)
[Compare Source](https://togithub.com/psf/requests/compare/v2.16.4...v2.16.5)
- Improvements to `$ python -m requests.help`.
### [`v2.16.4`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2164-2017-05-27)
[Compare Source](https://togithub.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://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2163-2017-05-27)
[Compare Source](https://togithub.com/psf/requests/compare/v2.16.2...v2.16.3)

reasons.
### [`v2.16.2`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2162-2017-05-27)
[Compare Source](https://togithub.com/psf/requests/compare/v2.16.1...v2.16.2)
- Further restored the `requests.packages` namespace for compatibility
reasons.
No code modification (noted below) should be necessary any longer.
### [`v2.16.1`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2161-2017-05-27)
[Compare Source](https://togithub.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
### [`v2.16.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2160-2017-05-26)
[Compare Source](https://togithub.com/psf/requests/compare/v2.15.1...v2.16.0)

[Compare Source](https://togithub.com/psf/requests/compare/v2.14.2...v2.15.0)
**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()`.
### [`v2.14.2`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2142-2017-05-10)
[Compare Source](https://togithub.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://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2141-2017-05-09)
[Compare Source](https://togithub.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://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2140-2017-05-09)
[Compare Source](https://togithub.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.
### [`v2.13.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2130-2017-01-24)
[Compare Source](https://togithub.com/psf/requests/compare/v2.12.5...v2.13.0)
**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.
### [`v2.12.5`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2125-2017-01-18)
[Compare Source](https://togithub.com/psf/requests/compare/v2.12.4...v2.12.5)
**Bugfixes**
- Fixed an issue with JSON encoding detection, specifically detecting
big-endian UTF-32 with BOM.
### [`v2.12.4`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2124-2016-12-14)
[Compare Source](https://togithub.com/psf/requests/compare/v2.12.3...v2.12.4)
**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
re-added, the behaviour is deprecated and will be removed in the
future.
### [`v2.12.3`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2123-2016-12-01)
[Compare Source](https://togithub.com/psf/requests/compare/v2.12.2...v2.12.3)
**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.
### [`v2.12.2`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2122-2016-11-30)
[Compare Source](https://togithub.com/psf/requests/compare/v2.12.1...v2.12.2)
**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`.
### [`v2.12.1`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2121-2016-11-16)
[Compare Source](https://togithub.com/psf/requests/compare/v2.12.0...v2.12.1)
**Bugfixes**
- Updated setuptools 'security' extra for the new PyOpenSSL backend in
urllib3.
**Miscellaneous**
- Updated bundled urllib3 to 1.19.1.
### [`v2.12.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2120-2016-11-15)
[Compare Source](https://togithub.com/psf/requests/compare/v2.11.1...v2.12.0)
**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.
### [`v2.11.1`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2111-2016-08-17)
[Compare Source](https://togithub.com/psf/requests/compare/v2.11.0...v2.11.1)
**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.
### [`v2.11.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2110-2016-08-08)
[Compare Source](https://togithub.com/psf/requests/compare/v2.10.0...v2.11.0)
**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.
### [`v2.10.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2100-2016-04-29)
[Compare Source](https://togithub.com/psf/requests/compare/v2.9.2...v2.10.0)
**New Features**
- SOCKS Proxy Support! (requires PySocks;
`$ pip install requests[socks]`)
**Miscellaneous**
- Updated bundled urllib3 to 1.15.1.
### [`v2.9.2`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#292-2016-04-29)
[Compare Source](https://togithub.com/psf/requests/compare/v2.9.1...v2.9.2)
**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.
### [`v2.9.1`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#291-2015-12-21)
[Compare Source](https://togithub.com/psf/requests/compare/v2.9.0...v2.9.1)
**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.
### [`v2.9.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#290-2015-12-15)
[Compare Source](https://togithub.com/psf/requests/compare/v2.8.1...v2.9.0)
**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 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.

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. ### [`v2.13.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2130-2017-01-24) [Compare Source](https://togithub.com/psf/requests/compare/v2.12.5...v2.13.0) **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. ### [`v2.12.5`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2125-2017-01-18) [Compare Source](https://togithub.com/psf/requests/compare/v2.12.4...v2.12.5) **Bugfixes** - Fixed an issue with JSON encoding detection, specifically detecting big-endian UTF-32 with BOM. ### [`v2.12.4`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2124-2016-12-14) [Compare Source](https://togithub.com/psf/requests/compare/v2.12.3...v2.12.4) **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 re-added, the behaviour is deprecated and will be removed in the future. ### [`v2.12.3`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2123-2016-12-01) [Compare Source](https://togithub.com/psf/requests/compare/v2.12.2...v2.12.3) **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. ### [`v2.12.2`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2122-2016-11-30) [Compare Source](https://togithub.com/psf/requests/compare/v2.12.1...v2.12.2) **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`. ### [`v2.12.1`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2121-2016-11-16) [Compare Source](https://togithub.com/psf/requests/compare/v2.12.0...v2.12.1) **Bugfixes** - Updated setuptools 'security' extra for the new PyOpenSSL backend in urllib3. **Miscellaneous** - Updated bundled urllib3 to 1.19.1. ### [`v2.12.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2120-2016-11-15) [Compare Source](https://togithub.com/psf/requests/compare/v2.11.1...v2.12.0) **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. ### [`v2.11.1`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2111-2016-08-17) [Compare Source](https://togithub.com/psf/requests/compare/v2.11.0...v2.11.1) **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. ### [`v2.11.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2110-2016-08-08) [Compare Source](https://togithub.com/psf/requests/compare/v2.10.0...v2.11.0) **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. ### [`v2.10.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2100-2016-04-29) [Compare Source](https://togithub.com/psf/requests/compare/v2.9.2...v2.10.0) **New Features** - SOCKS Proxy Support! (requires PySocks; `$ pip install requests[socks]`) **Miscellaneous** - Updated bundled urllib3 to 1.15.1. ### [`v2.9.2`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#292-2016-04-29) [Compare Source](https://togithub.com/psf/requests/compare/v2.9.1...v2.9.2) **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. ### [`v2.9.1`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#291-2015-12-21) [Compare Source](https://togithub.com/psf/requests/compare/v2.9.0...v2.9.1) **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. ### [`v2.9.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#290-2015-12-15) [Compare Source](https://togithub.com/psf/requests/compare/v2.8.1...v2.9.0) **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 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.
