**1.7.4** (2020-10-08)
======================
Small followup to 1.7.3 release.
Bugfixes
--------
* Fixed some Python 2.6 errors from last release (:issue:`128`)
Other Changes
-------------
* :mod:`passlib.ext.django` -- updated tests to pass for Django 1.8 - 3.1 (:issue:`98`);
along with some internal refactoring of the test classes.
* .. py:currentmodule:: passlib.context
:class:`CryptContext` will now throw :exc:`~passlib.exc.UnknownHashError` when it can't identify
a hash provided to methods such as :meth:`!CryptContext.verify`.
Previously it would throw a generic :exc:`ValueError`.
Deprecations
------------
* :mod:`passlib.ext.django`: This extension will require Django 2.2 or newer as of Passlib 1.8.
**1.7.3** (2020-10-06)
======================
This release rolls up assorted bug & compatibility fixes since 1.7.2.
Administrative Changes
----------------------
.. rst-class:: without-title
.. note::
**Passlib has moved to Heptapod!**
Due to BitBucket deprecating Mercurial support, Passlib's public repository and issue tracker
has been relocated. It's now located at `<https://foss.heptapod.net/python-libs/passlib>`_,
and is powered by `Heptapod <https://heptapod.net/>`_.
Hosting for this and other open-source projects graciously provided by the people at
`Octobus <https://octobus.net/>`_ and `CleverCloud <https://clever-cloud.com/>`_!
The mailing list and documentation urls remain the same.
New Features
------------
* .. py:currentmodule:: passlib.hash
:class:`ldap_salted_sha512`: LDAP "salted hash" support added for SHA-256 and SHA-512 (:issue:`124`).
Bugfixes
--------
* .. py:currentmodule:: passlib.hash
:class:`bcrypt`: Under python 3, OS native backend wasn't being detected on BSD platforms.
This was due to a few internal issues in feature-detection code, which have been fixed.
* :func:`passlib.utils.safe_crypt`: Support :func:`crypt.crypt` unexpectedly
returning bytes under Python 3 (:issue:`113`).
* :func:`passlib.utils.safe_crypt`: Support :func:`crypt.crypt` throwing :exc:`OSError`,
which can happen as of Python 3.9 (:issue:`115`).
* :mod:`passlib.ext.django`: fixed lru_cache import (django 3 compatibility)
* :mod:`!passlib.tests`: fixed bug where :meth:`HandlerCase.test_82_crypt_support` wasn't
being run on systems lacking support for the hasher being tested.
This test now runs regardless of system support.
Other Changes
-------------
* .. py:currentmodule:: passlib.hash
:class:`bcrypt_sha256`: Internal algorithm has been changed to use HMAC-SHA256 instead of
plain SHA256. This should strengthen the hash against brute-force attempts which bypass
the intermediary hash by using known-sha256-digest lookup tables (:issue:`114`).
* .. py:currentmodule:: passlib.hash
:class:`bcrypt`: OS native backend ("os_crypt") now raises the new :exc:`~passlib.exc.PasswordValueError`
if password is provided as non-UTF8 bytes under python 3
(These can't be passed through, due to limitation in stdlib's :func:`!crypt.crypt`).
Prior to this release, it confusingly raised :exc:`~passlib.exc.MissingBackendError` instead.
Also improved legacy bcrypt format workarounds, to support a few more UTF8 edge cases than before.
* Modified some internals to help run on FIPS systems (:issue:`116`):
In particular, when MD5 hash is not available, :class:`~passlib.hash.hex_md5`
will now return a dummy hasher which throws an error if used; rather than throwing
an uncaught :exc:`!ValueError` when an application attempts to import it. (Similar behavior
added for the other unsalted digest hashes).
.. py:currentmodule:: passlib.crypto.digest
Also, :func:`lookup_hash`'s ``required=False`` kwd was modified to report unsupported hashes
via the :attr:`HashInfo.supported` attribute; rather than letting ValueErrors through uncaught.
This should allow CryptContext instances to be created on FIPS systems without having
a load-time error (though they will still receive an error if an attempt is made to actually
*use* a FIPS-disabled hash).
* Internal errors calling stdlib's :func:`crypt.crypt`, or third party libraries,
will now raise the new :exc:`~passlib.exc.InternalBackendError` (a RuntimeError);
where previously it would raise an :exc:`AssertionError`.
* Various Python 3.9 compatibility fixes (including ``NotImplemented``-related warning, :issue:`125`)
