MySQL Connector/C 6.1.6 has been released

Dear MySQL users,

MySQL Connector/C 6.1.6, a new version of MySQL client library for
client/server communication for the MySQL database management system,
has been released.

This version of Connector/C provides full support for MySQL 5.6
protocol. Connector/C is compatible with the client libraries
(libmysql). It includes all the features in the MySQL client library
shipped with MySQL servers 5.6 as well as prior versions. You can
recompile existing code linked with Connector/C 6.1.6 without any code
changes.

You can use Connector/C to run and build client applications which
communicate with MySQL server versions from 5.5 to 5.6 without a need
to do a complete server installation.

The release is now available in source and binary form for a number
of platforms from our download pages at

   http://dev.mysql.com/downloads/connector/c/

MySQL Connector/C 6.1.6 will also be available for downloads via the
Oracle Software Delivery Cloud in approximately 1-2 weeks.

For information on installing, please see the documentation at

http://dev.mysql.com/doc/connector-c/en/connector-c-installation.html

Enjoy!


Changes in MySQL Connector/C 6.1.6 (2015-03-20)

    Security Notes

      * Connector/C 6.1.6 upgrades the linked OpenSSL library to
        version 1.0.1k. Issues fixed in the new version are
        described at
        http://www.openssl.org/news/vulnerabilities.html.

    Functionality Added or Changed

      * yaSSL sources included in Connector/C source packages and
        used in GPL binary distributions were upgraded to version
        2.3.7. (Bug #20201864)

    Bugs Fixed

      * For source packages, it was not possible to build
        Connector/C with the client protocol test trace plugin
        enabled. (Bug #20316149)

      * When there is no change in session state, the OK packet
        sent from server to the client contained an unneeded byte
        at the end of the packet. (Bug #19625718)

      * The client protocol trace plugin did not account for the
        removal of the EOF packet from the client/server protocol
        in MySQL 5.7.5. (Bug #19512199)

      * The mysql_session_track_get_first() and
        mysql_session_track_get_next() C API functions could
        cause a client crash if passed invalid arguments. (Bug
        #18769620)

      * mysql_config --libs_r produces output containing link
        flags for libmysqlclient_r, even though that library was
        removed in MySQL 5.5 and replaced with a symlink to the
        underlying libmysqlclient library. The output now refers
        directly to libmysqlclient. (The implication is that it
        is no longer necessary to maintain the symlink for the
        sake of being able to use mysql_config --libs_r.) (Bug
        #73724, Bug #19506315)

      * Invalid memory access could occur when using prepared
        statements if a mysql client connection was lost after
        statement preparation was complete and there was at least
        one statement that was in initialized state but not
        prepared yet. (Bug #70429, Bug #17512527)

      * Client auto-reconnect did not work for clients linked
        against libmysqlclient, even with MYSQL_OPT_RECONNECT
        enabled.
        Also, if a FEDERATED table was accessed after
        wait_timeout expired, a Lost connection to MySQL server
        error occurred without an attempt to re-establish the
        connection. (Bug #70026, Bug #17309863, Bug #14874, Bug
        #11745408)

      * mysql_real_connect() could close a file descriptor twice
        if the server was not running. (Bug #69423, Bug
        #19226740)
