MySQL Connector/Python 8.0.5 DMR has been released

Dear MySQL users,


MySQL Connector/Python 8.0.5 dmr is the sixth development release of the
MySQL Connector Python 8.0 series. This series adds support for the new X
DevAPI.  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 MySQL Server version 5.7.12 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/5.7/en/document-store.html.

To download MySQL Connector/Python 8.0.5 dmr, see the "Development
Releases" tab at http://dev.mysql.com/downloads/connector/python/

Enjoy!

Changes in MySQL Connector/Python 8.0.5 (2017-09-28, Development Milestone)

      * Packaging Notes

      * Functionality Added or Changed

    Packaging Notes

      * MySQL Connector/Python packages are now available in two
        formats: Pure Python packages that contain only Python
        files, and packages that contain the Python files plus
        the C Extension and C Protobuf extension. Exception
        platforms are Solaris, macOS, and Windows, for which
        packages containing the Python files and C extensions are
        available but not pure Python packages. (Bug #26648417)

    Functionality Added or Changed

      * MySQL Connector/Python now supports connections to MySQL
        accounts that use the caching_sha2_password
        authentication plugin (see SHA-2 Pluggable Authentication
        (http://dev.mysql.com/doc/refman/8.0/en/caching-sha2-plug
        gable-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.

      * MySQL Connector/Python now supports an auth connection
        option to specify the authentication methanism. Permitted
        values are plain, mysql41, and external. The option name
        and value are not case sensitive.
        If the authentication mechanism is not specified, it
        defaults to plain for secure (TLS) or Unix socket
        connections, or mysql41 for insecure connections.

      * MySQL Connector/Python now supports a pure Python
        implementation of Protobuf. Consequently, the Protobuf C
        extension has become optional. Connector/Python will use
        the Python implementation if the C extension is not
        available. The Protobuf Python package is required if it
        is desired not to use the C extension.
        The version requirements are Protobuf C++ 2.6.0 or
        higher, Protobuf Python 3.0.0 or higher.

      * A mysqlx.sessions variable is now exposed to scripts that
        can be used for session-related tasks such as saving or
        loading session configuration information.

      * These methods have been added for Collection:
        add_or_replace_one(), get_one(), replace_one(), and
        remove_one().

      * These methods have been added for FindStatement and
        SelectStatement, to enable shared and exclusive locks to
        be acquired: lock_shared() and lock_exclusive().

      * There is support for new forms of comparisons that use
        the IN operator:
item IN list
item IN document path
dict IN dict

        The left-hand-side value must be castable to the JSON
        type.
