The linked OpenSSL library for MySQL Connector/ODBC 5.3.9 Commercial has been updated to version 1.0.2l.

This change does not affect the Oracle-produced MySQL Community build of Connector/ODBC 5.3.9, which uses the yaSSL library instead. (Bug #26320994)

When compiling Connector/ODBC on Windows platforms, it can now be linked statically (equivalent to the /MT compiler option in Visual Studio) or dynamically (equivalent to the /MD compiler option in Visual Studio) to the Visual C++ runtime. The default option is to link dynamically; if you want to link statically. set the new CMake option, STATIC_MSVCRT, to true.

Another new CMake option, WITH_NODEFAULTLIB, has been introduced for specifying the Visual C++ runtime you want to link Connector/ODBC to when using mixed link types (that is, when link type to the Visual C++ runtime differs for Connector/ODBC and the MySQL client library it links to).

See Building Connector/ODBC from a Source Distribution on Windows for details. (WL #10890)

The SQLForeignKeys() function returned an empty result set when the information schema was being used. (Bug #26388694)

Calling SQLExecute() after calling SQLFreeStmt() with the SQL_RESET_PARAMS option resulted in an assertion failure. With this fix, a proper error is now thrown in the situation. (Bug #19148246)

A segmentation fault occurred in SQLFetch() when SQL_ATTR_CURSOR_TYPE was set to SQL_CURSOR_DYNAMIC. (Bug #18805392)

Connector/ODBC quit unexpectedly in SQLForeignKeys() when SQL_MODE was set to ANSI_QUOTES. (Bug #18641824)
