17.4.0

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


Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

*none*


Deprecations:
^^^^^^^^^^^^^

*none*


Changes:
^^^^^^^^


- Re-added a subset of the ``OpenSSL.rand`` module.
This subset allows conscientious users to reseed the OpenSSL CSPRNG after fork.
`708 <https://github.com/pyca/pyopenssl/pull/708>`_
- Corrected a use-after-free when reusing an issuer or subject from an ``X509`` object after the underlying object has been mutated.
`709 <https://github.com/pyca/pyopenssl/pull/709>`_

----

17.3.0

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


Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Dropped support for Python 3.3.
`677 <https://github.com/pyca/pyopenssl/pull/677>`_
- Removed the deprecated ``OpenSSL.rand`` module.
This is being done ahead of our normal deprecation schedule due to its lack of use and the fact that it was becoming a maintenance burden.
``os.urandom()`` should be used instead.
`675 <https://github.com/pyca/pyopenssl/pull/675>`_


Deprecations:
^^^^^^^^^^^^^

- Deprecated ``OpenSSL.tsafe``.
`673 <https://github.com/pyca/pyopenssl/pull/673>`_

Changes:
^^^^^^^^

- Fixed a memory leak in ``OpenSSL.crypto.CRL``.
`690 <https://github.com/pyca/pyopenssl/pull/690>`_
- Fixed a memory leak when verifying certificates with ``OpenSSL.crypto.X509StoreContext``.

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

**Bugfixes**

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

2.20.0

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

**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**

- Requests has officially stopped support for Python 2.6.

2.19.1

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

**Bugfixes**

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

2.19.0

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

**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**

-   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.
