Release date: 14 Mar 2025

This is a Stable (GA) release of MariaDB Connector/C++.

For a description of this library see theMariaDB Connector/C++ page.

MariaDB Connector/C++ is the interface between C++ applications and MariaDB Server. MariaDB Connector/C++ enables development of C++ applications using a JDBC-based API, which is also used by MariaDB Connector/J.

MariaDB Connector/C++ implements the MySQL protocol using the MariaDB Connector/C API. This release depends on MariaDB Connector/C 3.3.14.

Notable Changes

• CONCPP-138 - The Driver now always cache all binary results to avoid access violation error while using result-set created with server prepared statements after the connection object has been closed. In case result-set streaming is used results naturally are not cached, but operations on the result-set after statement/connection is closed will cause SQLException to be thrown that the result-set is closed because of that

• CONCPP-140 - reconnect and reset methods in the Connection interface are deprecated

• CONCPP-141 - if trustServerCertificate is true(this is default) the connector will explicitly disable certificate verification. This enables work of the connector with Connector/C v.3.4 for unencrypted connection on the platforms there Connector/C is linked dynamically. Setting the option to false enables certificate verification.

• Fixed possible crash in case of use of setBytes() method if passed sql::bytes object did not own the bytes array, but referenced C array

Bugs Fixed

• CONCPP-134 - Removed volatile deprecation build warnings

• CONCPP-136 - With default settings the driver uses slowest possible batch executing method

• CONCPP-137 - Inconsistent types naming of the names returned by ResultSetMetaData::getColumnTypeName()
