Changes in MySQL Connector/Python 2.1.8 (2018-08-31, General Availability)

   Known limitation: MySQLConnection.cmd_change_user() with the C
   extension enabled does not establish a connection with the changed
   user. Instantiate a new MySQLConnection() connection as a workaround.

Functionality Added or Changed


     * MySQL Connector/Python now supports connections to MySQL
       accounts that use the caching_sha2_password authentication plugin
       (see Caching SHA-2 Pluggable Authentication
(http://dev.mysql.com/doc/refman/8.0/en/caching-sha2-pluggable-authentication.html)).
       This requires MySQL server version 8.0.3 or higher. It also
       requires use of a secure connection because Connector/Python does
       not support RSA encryption for password exchange.

Bugs Fixed

     * On Windows, the 32-bit MSI failed to install. The
       registry key path was updated to allow the CEXT
       prerequisite check to execute and pass. (Bug #28395599,
       Bug #28464866)

     * In pure Python mode, connecting to a MySQL server with
       default_authentication_plugin = caching_sha2_password would fail,
       even for accounts not using caching_sha2_password, because the
       authentication plugin was unknown to the Python connector.
       (Bug #27371245)

     * When using prepared statements, string columns were
       returned as bytearrays instead of strings. The returned value is
       now a string decoded using the connection's charset (defaults to
       'utf8'), or as a bytearray if this conversion fails.
       (Bug #27364914)

     * Connecting to a MySQL server configured to use TLS
       versions other than TLSv1, such as as TLSv1.1 and TLSv1.2), was
       not possible and failed with a "[SSL: WRONG_VERSION_NUMBER] wrong
       version number" error. This is because the connector restricted
       the connection to use TLSv1.  In addition, tsl_version support
       was added. (Bug #26484601, Bug #87121)

     * The result from JSON_TYPE() was returned as a bytearray
       instead of a string. The returned value is now a string decoded
       using the connection's charset (defaults to 'utf8'), or as a
       bytearray if this conversion fails. (Bug #24948205, Bug #83516)

     * JSON integer values were cast to bytes in Python instead
       of integers. (Bug #24948186, Bug #83513)

Enjoy and thanks for the support!
