MySQL Connector/ODBC 5.3.6 has been released

Dear MySQL users,

MySQL Connector/ODBC 5.3.6, a new version of the ODBC driver for
the MySQL database management system, has been released.

The available downloads include both a Unicode driver and an ANSI
driver based on the same modern codebase. Please select the driver type
you need based on the type of your application - Unicode or ANSI.
Server-side prepared statements are enabled by default. It is suitable
for use with any MySQL version from 5.5 onward.

This is the third release of the MySQL ODBC driver conforming to the
ODBC 3.8 specification. It contains implementations of key 3.8 features,
including self-identification as a ODBC 3.8 driver, streaming of output
parameters (supported for binary types only), and support of the
SQL_ATTR_RESET_CONNECTION connection attribute (for the Unicode driver

Also, Connector/ODBC 5.3 introduces a GTK+-based setup library
providing a GUI DSN setup dialog on some Unix-based systems, currently
included in the Oracle Linux 6 and Debian 6 binary packages. Other new
features in the 5.3 driver are FileDSN and Bookmarks support.

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

Changes in MySQL Connector/ODBC 5.3.6 (2016-03-17)

   Security Notes

     * Security Fix: The linked OpenSSL library for
       Connector/ODBC Commercial 5.3.6 has been updated from
       version 1.0.1m to version 1.0.1q. Versions of OpenSSL
       prior to 1.0.1q are reported to be vulnerable to
       This change does not affect the Oracle-produced MySQL
       Community build of Connector/ODBC 5.3.6, which uses the
       yaSSL library instead. (CVE-2015-3195)

   Functionality Added or Changed

     * Two new option parameters, DISABLE_SSL_DEFAULT and
       SSL_ENFORCE, have been introduced for specifying whether
       the default requirement to use SSL connections is to be
       followed. See Connector/ODBC Option Parameters
(http://dev.mysql.com/doc/connector-odbc/en/connector-odb <http://dev.mysql.com/doc/connector-odbc/en/connector-odbc-configuration-connection-parameters.html#codbc-dsn-option-flags> c <http://dev.mysql.com/doc/connector-odbc/en/connector-odbc-configuration-connection-parameters.html#codbc-dsn-option-flags>-configuration-connection-parameters.html#codbc-dsn-opti <http://dev.mysql.com/doc/connector-odbc/en/connector-odbc-configuration-connection-parameters.html#codbc-dsn-option-flags> on-flags <http://dev.mysql.com/doc/connector-odbc/en/connector-odbc-configuration-connection-parameters.html#codbc-dsn-option-flags>) for details. (Bug #21027928)

   Bugs Fixed

     * The function MySQLGetPrivateProfileStringW() used
       malloc() to allocate memory and then xfree() to free the
       allocated memory for a returned value. That caused some
       issues when certain third-party versions of MySQL client
       library (like MariaDB 10.x) was used. The issues have
       been fixed by replacing malloc() with my_malloc(). (Bug
       #21074676, Bug #76984)

     * Attempt to build Connector/ODBC from source on a Linux
       platform against the client library and header files
       shipped with MySQL server 5.7.6 or newer failed. It was
       due to the changes made to the client library and the
       header files, to which Connector/ODBC has now been
       adapted. (Bug #20685833)

     * An application that used ActiveX Data Objects (ADO) and
       the Connector/ODBC ANSI driver hung after trying to write
       French characters to a database that used the UTF-8
       character set. (Bug #20526062)

     * Calling the SQLGetDiagField function with the
       DiagIdentifier SQL_DIAG_ROW_COUNT always returned "0,"
       even if there were updated, deleted, or modified rows.
       (Bug #16920750)

     * Because Connector/ODBC did not parse comments properly,
       the parameter markers embedded in comments caused the
       complaint that SQLBindParameter was not used for all
       parameters. (Bug #16613308, Bug #53891)
