[pyup-bot]

This PR updates mysqlclient from 1.3.12 to 2.1.0.

Changelog

2.1.0

======================

Release: 2021-11-17

* Add ``multistatement=True`` option. You can disable multi statement. (500).
* Remove unnecessary bytes encoder which is remained for Django 1.11
compatibility (490).
* Deprecate ``passwd`` and ``db`` keyword. Use ``password`` and ``database``
instead. (488).
* Windows: Binary wheels are built with MariaDB Connector/C 3.2.4. (508)
* ``set_character_set()`` sends ``SET NAMES`` query always. This means
all new connections send it too. This solves compatibility issues
when server and client library are different version. (509)
* Remove ``escape()`` and ``escape_string()`` from ``MySQLdb`` package.
(511)
* Add Python 3.10 support and drop Python 3.5 support.

* Add ``-std=c99`` option to cflags by default for ancient compilers that doesn't
accept C99 by default.
* You can customize cflags and ldflags by setting ``MYSQLCLIENT_CFLAGS`` and
``MYSQLCLIENT_LDFLAGS``. It overrides ``mysql_config``.

* Optimize fetching many rows with DictCursor.

1.4.6

======================

before ``mysql_real_connect`` is called.
This avoid extra ``SET NAMES <charset>`` query when creating connection.


======================

1.4.3

======================

1.4.2

======================

Release: 2019-02-08

* Fix Django 1.11 compatibility. (327)
mysqlclient 1.5 will not support Django 1.11.  It is not because
mysqlclient will break backward compatibility, but Django used
unsupported APIs and Django 1.11 don't fix bugs including
compatibility issues.

======================

Release: 2019-01-19

objects are called after ``Connection.close()`` is called. (270, 272, 276)

* Fix ``Connection.client_flag`` (266)

* Fix SSCursor may raise same exception twice (282)

* This removed ``Cursor._last_executed`` which was duplicate of ``Cursor._executed``.
 Both members are private.  So this type of changes are not documented in changelog
 generally.  But Django used the private member for ``last_executed_query`` implementation.
 If you use the method the method directly or indirectly, this version will break
 your application.  See https://code.djangoproject.com/ticket/30013
