This release of the MySQL ODBC driver is conforming to the ODBC 3.8

binary types only), and support of the SQL_ATTR_RESET_CONNECTION

Changes in MySQL Connector/ODBC 8.0.21 (2020-07-13, General Availability)


     * Security Notes

     * Bugs Fixed

Security Notes


     * For platforms on which OpenSSL libraries are bundled, the
       linked OpenSSL library for Connector/ODBC has been
       updated to version 1.1.1g. Issues fixed in the new
       OpenSSL version are described at
       https://www.openssl.org/news/cl111.txt and
       https://www.openssl.org/news/vulnerabilities.html. (Bug
       #31296688)

Bugs Fixed


     * The MSI installer now checks for the Visual 2019 C++
       runtime, and aborts if this required runtime is not
       installed.
       This is also the first version that requires Visual 2019
       C++ runtime, when before the 2017 version was also
       supported. (Bug #31102234)

     * Only a single value was being inserted instead of the
       array, with SQLParamOptions. (Bug #30591722)

     * The SUM aggregate function did not function with ADO.
       (Bug #30277891, Bug #96642)

     * Added a workaround to account for a limitation in the
       iODBC SQLGetPrivateProfileString() implementation as
       previously DSN options could be lost. iODBC is most
       commonly used on macOS. (Bug #27851681)
