Log Message:
py-mysqlclient: updated to 1.4.5

What's new in 1.4.5
* The ``auth_plugin`` option is added.

What's new in 1.4.4
* ``charset`` option is passed to ``mysql_options(mysql, MYSQL_SET_CHARSET_NAME, \ 
charset)``
  before ``mysql_real_connect`` is called.
  This avoid extra ``SET NAMES <charset>`` query when creating connection.

What's new in 1.4.3
* ``--static`` build supports ``libmariadbclient.a``
* Try ``mariadb_config`` when ``mysql_config`` is not found
* Fixed warning happend in Python 3.8
* Fixed ``from MySQLdb import *``, while I don't recommend it.
* Fixed SEGV ``MySQLdb.escape_string("1")`` when libmariadb is used and
  no connection is created.
* Fixed many circular references are created in ``Cursor.executemany()``.

What's new in 1.4.2
* Fix Django 1.11 compatibility.
  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.

What's new in 1.4.1
* Fix dict parameter support

What's new in 1.4.0
* Dropped Python 3.4 support.
* Removed ``threadsafe`` and ``embedded`` build options.
* Remove some deprecated cursor classes and methods.
* ``_mysql`` and ``_mysql_exceptions`` modules are moved under
  ``MySQLdb`` package.
* Remove ``errorhandler`` from Connection and Cursor classes.
* Remove context manager API from Connection.  It was for transaction.
  New context manager API for closing connection will be added in future version.
* Remove ``waiter`` option from Connection.
* Remove ``escape_sequence``, and ``escape_dict`` methods from Connection class.
* Remove automatic MySQL warning checking.
* Drop support for MySQL Connector/C with MySQL<5.1.12.
* Remove ``_mysql.NULL`` constant.
* Remove ``_mysql.thread_safe()`` function.
* Support non-ASCII field name with non-UTF-8 connection encoding.
* Optimize decoding speed of string and integer types.
* Remove ``MySQLdb.constants.REFRESH`` module.
* Remove support for old datetime format for MySQL < 4.1.

What's new in 1.3.14
* Support static linking of MariaDB Connector/C
* Better converter for Decimal and Float
* Add ``Connection._get_native_connection`` for XTA project
* Fix SEGV on MariaDB Connector/C when some methods of ``Connection``
  objects are called after ``Connection.close()`` is called.
* Fix ``Connection.client_flag``
* Fix SSCursor may raise same exception twice
  * 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
* ``waiter`` option is now deprecated.
* Fixed SSL support is not detected when built with MySQL < 5.1
