Changes in MySQL Connector/ODBC 5.1.13 

Functionality Added or Changed

  * Added a lock in the ENV structure against simultaneous accesses to
    an environment handle's connection list, in order to avoid memory
    access issues that might occur when multiple threads share the same
    environment handle. (Bug #17240611, Bug #69864)

  * Clear text authentication to MySQL servers is now supported by
    Connector/ODBC. The support is controlled by the new Enable
    Cleartext Authentication connection option (with the flag name
    ENABLE_CLEARTEXT_PLUGIN). (Bug #16445091)

Bugs Fixed

  * The exit condition for a for loop in stringutil.c is changed to
    avoid a possible out-of-bounds error and the associated reports by
    Valgrind. (Bug #17397596, Bug #64105)

  * Microsoft Visual Studio 2010 crashed when reading rows from any
    table in Server Explorer with connections to DSNs made by
    Connector/ODBC. (Bug #17304031, Bug #69950)

  * When trying to create a linked server in Micrsoft SQL Server 2008 to
    a MySQL server set up with Connector/ODBC as a DSN, the Microsoft
    SQL Server (if it is a 64-bit version) crashed or the linked server
    suffered a catastrophic failure (if a 32-bit version of the
    Microsoft SQL Server is used). (Bug #16604346, Bug #63386)

  * A data connection could not be opened in Microsoft Word 2010 for
    mail merges that attempted to use an ODBC DSN.
    (Bug #16526604, Bug #63844)

  * Trailing zeros for the fractional part of the second for datetime
    and timestamp values were not removed for MySQL server version 5.5
    or earlier, which do not support fractional second.
    (Bug #16294197, Bug #65418)

  * Connector/ODBC used the ";" character instead of a null byte ("\0")
    to terminate keyword-value pairs in attribute strings.
    (Bug #15940689, Bug #66548)

  * The configured values of a DSN's parameters overrode the values
    provided through the connection string, instead of the other way
    round. (Bug #11760574, Bug #52996)
Built against the MySQL server 5.6.14 client library.
