Dear MySQL users,

MySQL Connector/Python 8.0.18 is the latest GA release version of the
MySQL Connector Python 8.0 series. The X DevAPI enables application
developers to write code that combines the strengths of the relational
and document models using a modern, NoSQL-like syntax that does not
assume previous experience writing traditional SQL.

To learn more about how to write applications using the X DevAPI, see

http://dev.mysql.com/doc/x-devapi-userguide/en/

For more information about how the X DevAPI is implemented in MySQL
Connector/Python, and its usage, see

http://dev.mysql.com/doc/dev/connector-python

Please note that the X DevAPI requires at least MySQL Server version 8.0
or higher with the X Plugin enabled. For general documentation about how
to get started using MySQL as a document store, see

http://dev.mysql.com/doc/refman/8.0/en/document-store.html

To download MySQL Connector/Python 8.0.18, see the “General Availability
(GA) Releases” tab at

Enjoy!


Changes in MySQL Connector/Python 8.0.18 (2019-10-14, General Availability)

Functionality Added or Changed


     * Added Python 3.8 support.

     * Connector/Python connections now set
       CAN_HANDLE_EXPIRED_PASSWORDS to indicate it can handle
       sandbox mode for expired passwords. This indicates that
       Connector/Python does not execute SET commands by a
       connection with an expired password, an operation that’s
       disallowed by MySQL Server 8.0.18 and higher.

     * On Windows, added platform dependent MSI installers that
       install and update Connector/Python for all supported
       Python versions on the system. Downloading and installing
       separate packages for each version is no longer required.

Bugs Fixed


     * The /usr/lib/mysqlx folder was not created after
       executing setup.py from commercial packages. (Bug
       #29959309)

     * A table scan for a float using the C Extension caused a
       memory leak. (Bug #29909157)

     * Added read_default_file as an alias for option_files to
       increase MySQLdb compatibility. (Bug #25349794, Bug
       #84389)

     * Connector/Python 8.0.17 does not properly negotiate the
       highest TLS protocol version supported by both the client
       and server. As such, because MySQL 5.6/5.7 platform
       packages (DEB and RPM) include YaSSL prior to
       5.6.45/5.7.27, and YaSSL only supports up to TLS 1.1,
       systems setting a minimum TLS protocol version above 1.1
       (such as Debian 10 that sets MinProtocol=TLSv1.2) do not
       function with Connector/Python 8.0.17.
       As a workaround, the wheel (pip) packages function
       properly as they are built using glibc and bundle OpenSSL
       instead of YaSSL.
       Connector/Python 8.0.18 adds a tls-versions option to
       define the TLS version to use.

Enjoy and thanks for the support!
