Dear MySQL users,

MySQL Connector/J 8.0.7 Development Release is a development milestone
release for the 8.0.x series.
This release includes the following new features and changes, also described
in more detail on
https://dev.mysql.com/doc/relnotes/connector-j/8.0/en/news-8-0-7.html

MySQL Connectors and other MySQL client tools and applications now
synchronize the first digit of their version number with the (highest)
MySQL server version they support.
This change makes it easy and intuitive to decide which client version
to use for which server version.

Connector/J 8.0.7 is the first release to use the new numbering.
It is the successor to Connector/J 6.0.6

As always, we recommend that you check the "CHANGES" file in the download
archive to be aware of changes in behavior that might affect your application.

Changes in MySQL Connector/J 8.0.7 (2017-07-10, Development Milestone)

   MySQL Connectors and other MySQL client tools and
   applications now synchronize the first digit of their version
   number with the (highest) MySQL server version they support.
   This change makes it easy and intuitive to decide which
   client version to use for which server version.

   Connector/J 8.0.7 is the first release to use the new
   numbering. It is the successor to Connector/J 6.0.6.

     * Functionality Added or Changed

     * Bugs Fixed

   Functionality Added or Changed

     * X DevAPI: There are changes to some methods related to
       the Result interface:

          + getLastDocumentId() and getLastDocumentIds() have
            been replaced with getDocumentId() and
            getDocumentIds(), which are put under a new
            AddResult interface that extends Result.

          + A new getAutoIncrementValue() method is added to the
            new InsertResult interface that extends Result.
       See MySQL Connector/J X DevAPI Reference
       http://dev.mysql.com/doc/dev/connector-j for more
       details. (Bug #25207784)

     * X DevAPI: It is no longer permitted to pass an empty
       search condition, such as the NULL value or an empty
       string, to the Collection.Modify() and
       Collection.Remove() methods.

     * X DevAPI: Connections using the X Protocol are now secure
       by default. Also, the xdevapi.ssl-enable connection
       option has been replaced by the xdevapi.ssl-mode option,
       which has DISABLED, REQUIRED (default), VERIFY_CA, and
       VERIFY_IDENTITY as its permitted values; see the
       description for the new option in Configuration
       Properties
       http://dev.mysql.com/doc/connector-j/8.0/en/connector-j-reference-configuration-properties.html
       for details.

     * X DevAPI: Consolidated the BaseSession, NodeSession, and
       XSession interfaces into a single
       com.mysql.cj.api.xdevapi.Session interface. The following
       related changes were also made:

          + Renamed XSessionFactory to SessionFactory.

          + Consolidated the AbstractSession, NodeSessionImpl,
            and XSessionImpl classes into the
            com.mysql.cj.xdevapi.SessionImpl class.

          + Removed the Session.bindToDefaultShard() method and
            the VirtualNodeSession interface.

          + The mysqlx.getNodeSession() method has been renamed
            to mysqlx.getSession() and it now returns a Session
            object.

          + The DatabaseObject.getSession() method now returns a
            Session object (instead of the old Session
            interface).
       See MySQL Connector/J X DevAPI Reference
       http://dev.mysql.com/doc/dev/connector-j for more
       details.

     * To avoid using JDBC statements inside core Connector/J
       classes, the following changes have been implemented:

          + Created a new com.mysql.cj.api.Query interface,
            which is implemented by StatementImpl.

          + Replaced the
            com.mysql.cj.api.jdbc.interceptors.StatementIntercep
            tor interface with the
            com.mysql.cj.api.interceptors.QueryInterceptor
            interface.

          + Added a new method, PacketPayload
            preProcess(PacketPayload queryPacket), to
            QueryInterceptor.

          + Renamed the connection property
            statementInterceptors to queryInterceptors. See
            Configuration Properties
            http://dev.mysql.com/doc/connector-j/8.0/en/connector-j-reference-configuration-properties.html
            for details.

     * Added Japanese collation for the utf8mb4 character set.

   Bugs Fixed

     * X DevAPI: createView() failed with a NullPointerException
       when there were null inputs to it. This fix adds checks
       for nulls, and makes Connector/J throw the proper errors
       for them. (Bug #25575156)

     * X DevAPI: createaTable() failed with a
       NullPointerException when there were null inputs to it.
       This fix adds checks for nulls, and makes Connector/J
       throw the proper errors for them. (Bug #25575103)

     * X DevAPI: The connection properties
       enabledSSLCipherSuites, clientCertificateKeyStoreUrl,
       clientCertificateKeyStoreType, and
       clientCertificateKeyStorePassword were ignored for
       connections using the X Protocol. (Bug #25494338)

     * X DevAPI: Calling getNodeSession() with an URL string
       containing SSL parameters caused a
       CJCommunicationsException. This has been fixed by
       creating a byte buffer to handle SSL handshake data.
       (Notice that getNodeSession() has since been consolidated
       into getSession().) (Bug #23597281)

     * X DevAPI: Concurrent asynchronous operations resulted in
       hangs, null pointer exceptions, or other unexpected
       exceptions. This has been fixed by correcting a number of
       problems with the SerializingBufferWriter and by limiting
       the number of buffers sent with a gathering write. (Bug
       #23510958)

     * X DevAPI: When a thread failed to make a connection to
       the server using the X Protocol, the client application
       hung. A new connection property,
       xdevapi.asyncResponseTimeout (default value is 300s), now
       provides a duration beyond which the attempt to connect
       timeouts, and a proper error is then thrown. See
       description for the new option in Configuration
       Properties
       http://dev.mysql.com/doc/connector-j/8.0/en/connector-j-reference-configuration-properties.html
       for details. (Bug #22972057)

     * Connector/J failed a number of regression tests in the
       test suite related to geographic information system (GIS)
       functions, because of changes to GIS support by the MySQL
       server. The fix corrects the tests. (Bug #26239946, Bug
       #26140577)

     * Configuration templates named by the connection property
       useConfigs were not recognized by Connector/J. (Bug
       #25757019, Bug #85555)

     * A NullPointerException was returned when getDate(),
       getTime(), or getTimestamp() was called with a null
       Calendar. This fix makes Connector/J throw an
       SQLException in the case. (Bug #25650305)

     * An ArrayIndexOutOfBoundsException was thrown when a
       server-side prepared statement was used and there was a
       NULL in a BLOB, TEXT, or JSON type column in the
       ResultSet. (Bug #25215008, Bug #84084)
