Dear MySQL users,

MySQL Connector/Python 8.0.23 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 8.0.23, see the "General Availability
(GA) Releases" tab at

Enjoy!

Changes in MySQL Connector/Python 8.0.23 (2021-01-18, General Availability)

Functionality Added or Changed

     * Deprecated Python 2.7 support; a warning was added to
       describe Python 2.7 support being removed in
       Connector/Python 8.0.24.

     * Previously, Connector/Python added client support for the
       MySQL Enterprise Edition SASL LDAP authentication plugin
       with SCRAM-SHA-1 as an authentication method.
       Connector/Python now also supports SCRAM-SHA-256 as an
       alternative authentication method for classic MySQL
       protocol connections. SASL-based LDAP authentication does
       not apply to clients running macOS.

     * Added SASL authentication protocol support using the
       GSSAPI (Kerberos) authentication method for the pure
       python implementation (this is not available for the
       c-ext version of Connector/Python).

       This functionality requires the GSSAPI pypi module, which
       provides both low-level and high-level wrappers around
       the GSSAPI C libraries. The GSSAPI pypi module requires
       MIT kerberos installed opn the system to function and
       request tickets to authenticate Connector/Python with the
       MySQL server when the user is IDENTIFIED WITH
       authentication_ldap_sasl and the authentication_ldap_sasl
       plugin is configured to use the GSSAPI mechanism.

       This also adds a new krb_service_principal option, which
       must be a string in the form "primary/instance@realm"
       such as "ldap/ldapauth@MYSQL.COM" where "@realm" is
       optional. The "@realm" defaults to the default realm, as
       configured in the krb5.conf file.

Bugs Fixed

     * Fixed the AttributeError raised when getting the
       connection ID from a closed CMySQLConnection.
       (Bug #31882419, Bug #100825)

     * Fixed support for named tuple (an invalid exception was
       generated) and dictionary cursors (incorrect type of
       result was returned). (Bug #29195610)

     * Fixed cursor.fetchone() and cursor.fetchmany() to comply
       with PEP 249, which specifies that an exception must be
       raised if the previous call to cursor.execute*() does not
       produce any result set or no call was issued yet.
       (Bug #26834307, Bug #87815)

     * Fixed the microsecond conversion from MySQL datetime to
       Python datetime when using fractional values with the C
       extension enabled. For example, 2016-10-20 15:40:23.8
       from MySQL resulted in datetime.datetime(2016, 10, 20,
       15, 40, 23, 8) instead of datetime.datetime(2016, 10, 20,
       15, 40, 23, 800000). Thanks to Vilnis Termanis for the
       patch. (Bug #24938411, Bug #83479)
