Release 1.3 of the POCO C++ Libraries is the first official release containing the Data library. The Data library has been available in a development state for the 1.2 release. For the 1.3 release, a few things have been changed in an incompatible way that requires changes to existing code.
SessionInstantiator has been renamed Poco::Data::Connector, and the member functions addToFactory() and removeFromFactory() are now named registerConnector() and unregisterConnector(), respectively. This requires a change in all applications already using POCO Data.
