MySQL Connector/C++ 2.0.3 is the next development milestone of the MySQL Connector/C++ 2.0 series, and the first public release. Apart from covering more X DevAPI features, it adds a new, plain C API, called X DevAPI for C, that offers functionality similar to X DevAPI to applications written in plain C. Thus, not only can MySQL Connector/C++ be used to write C++ applications, as before. Now, using the X DevAPI for C, MySQL Connector/C++ can be used to write plain C applications to access MySQL Database implementing a document store as well as execute traditional plain SQL statements. For more information about X DevAPI for C, refer to the documentation at https://dev.mysql.com/doc/dev/connector-cpp/xapi_ref.html.
The X DevAPI requires at least MySQL Server version 5.7.12 or higher with the X Plugin enabled. For general documentation about how to get started using MySQL as a document store, see Using MySQL as a Document Store.
