Released 3.4.0 2021-09-17

This release requires Python 3.6 or above,

and is tested with Python 3.6 to 3.10.

Python 2 is no longer supported.

New code in the python-ldap project is available under the MIT licence

(available in ``LICENCE.MIT`` in the source). Several contributors have agreed

to apply this licence their previous contributions as well.

See the ``README`` for details.

The following undocumented functions are deprecated and scheduled for removal:

- ``ldap.cidict.strlist_intersection``

- ``ldap.cidict.strlist_minus``

- ``ldap.cidict.strlist_union``

Changes:

* On MacOS, remove option to make LDAP connections from a file descriptor

when built with the system libldap (which lacks the underlying function,

``ldap_init_fd``)

* Attribute values of the post read control are now ``bytes``

instead of ISO8859-1 decoded ``str``

* ``LDAPUrl`` now treats urlscheme as case-insensitive

* Several OpenLDAP options are now supported:

* ``OPT_X_TLS_REQUIRE_SAN``

* ``OPT_X_SASL_SSF_EXTERNAL``

* ``OPT_X_TLS_PEERCERT``

Fixes:

* The ``copy()`` method of ``cidict`` was added back. It was unintentionally

removed in 3.3.0

* Fixed getting/setting ``SASL`` options on big endian platforms

* Unknown LDAP result code are now converted to ``LDAPexception``,

rather than raising a ``SystemError``.

slapdtest:

* Show stderr of slapd -Ttest

* ``SlapdObject`` uses directory-based configuration of ``slapd``

* ``SlapdObject`` startup is now faster

Infrastructure:

* CI now runs on GitHub Actions rather than Travis CI.
