Connector/C++ 8.3.0 binary distributions from Oracle are built with the 8.3.0 version of the MySQL client library. MySQL Server 8.3.0 removed auto-reconnect support after deprecating it in versions 8.0.34 and 8.1.0. The related
OPT_RECONNECTconnection option continues to be recognized by the connector, but enabling the option now has no effect on the connection. Applications that use the legacy JDBC API and also enable
Implement reconnect logic in the application code.
Build JDBC Connector/C++ from sources in combination with an older version of the MySQL client library. However, enabling the
OPT_RECONNECToption does guarantee a successful automatic reconnection to the server if the connection is found to have been lost.
Improved OpenTelemetry support to propagate context when executing prepared statements. (WL #15959)
Improved support to import Connector/C++ into CMake projects by allowing
find_package(mysql-concpp)to enable consuming it. This defines import targets such as
mysql::concppthat can be linked to executables used by the connector. (WL #15952)
