   Version 6.0.6 Milestone is the fifth development release of
   the 6.0 branch of MySQL Connector/J, providing an insight

     * Functionality Added or Changed

     * Bugs Fixed

   Functionality Added or Changed

     * X DevAPI: The getPluginVersion() method has been removed
       from Connector/J, as it is no longer supported by the X
       Protocol. (Bug #25056803)

     * IPv6 host addresses are now supported for connections
       using the X Protocol.

     * X DevAPI: The following new connection options have been
       added for SSL/TLS configuration:

          + xdevapi.ssl-enable

          + xdevapi.ssl-truststore

          + xdevapi.ssl-verify-server-certificate
       See Configuration Properties
       for details.

     * Connector/J now supports the new character set collations
       implemented in MySQL Server 8.0. See Unicode Character
       for details.

     * X DevAPI: DDL for views are now supported by the new
       methods createView(), dropView(), and alterView().
       However, the functions do not support partitioning in an
       InnoDB cluster or sharding.

     * X DevAPI: The Connector/J X Dev API has been reorganized:

          + All interfaces for public usage have been moved to
            the com.mysql.cj.api.xdevapi package, and their
            implementation classes to com.mysql.cj.xdevapi.

          + All Connector/J internal interfaces have been moved
            to the com.mysql.cj.api.x.core and
   packages, and their
            implementation classes to com.mysql.cj.x.core and

          + Protobuf generated classes have been moved to the
            com.mysql.cj.x.protobuf package.

          + The MysqlxSessionFactory has been renamed

   Bugs Fixed

     * When Connector/J was reading a TIMESTAMP value into an
       instance of a JSR-310 data type, the reading was wrong
       when the time did not exist in the local time zone of the
       JVM due to a time change for Daylight Saving Time. It was
       because Connector/J created first a java.sql.Timestamp
       instance (which used the JVM's time zone) for the value
       and then converted it to, for example,
       java.time.LocalDateTime. With this fix, a JSR-310 object
       is created directly to avoid the conversion. (Bug
       #24658016, Bug #82964)

     * Query executions using prepared statements failed with
       the error "Unknown ProtocolEntity class null" when the
       connection property useCursorFetch was set to true. (Bug

     * When server-side prepared statements were used, updates
       to result sets failed in errors. (Bug #24525461)

     * The getString() method returned wrong millisecond values
       for the TIMESTAMP data type. (Bug #24512766, Bug #82707)

     * Updates to a document object of the Dbdoc type failed
       when the document contained an array. (Bug #24471057)

     * The method isNumberSigned() returned true for columns of
       type VARCHAR, which was wrong as it should return false
       for any non-numeric columns, according to the JDBC
       Specification. The behavior has now been corrected. (Bug

     * An IllegalArgumentException was thrown when lenient was
       false for a Calendar object and the hours, minutes, and
       seconds explicitly set via the Calendar constructor did
       not match the values resulted from the timezone
       conversion of the Calendar object's date value. (Bug
       #23702040, Bug #82005)

     * X DevAPI: The getLastDocumentIds() method only reported
       document IDs specified by users, but not those generated
       by Connector/J. With this fix, all IDs are now reported.
       (Bug #23519211)

     * A connection failed with IllegalStateException:
       TrustManagerFactoryImpl is not initialized after
       Connector/J set (Bug #23510894)

     * A NullPointerException was thrown when a NULL object of
       any of the classes defined in the java.time package was
       retried by the ResultSet.getObject() method. (Bug
       #23188159, Bug #81202)

     * The getType() method returned errors on columns of YEAR
       and DATETIME data types. (Bug #22931277)
