Version 1.0.3-alpha of the MySQL Connector/C++ has just been announced by Lawrin Novitsky and is now available for download. This driver is licensed under the GPL and is a new implementation of the MySQL Client/Server protocol. Instead of wrapping the C API calls in C++ methods, the implementation mimics the JDBC API, which hopefully feels much more "native" to a seasoned C++ developer.
The driver has been ported to a wide range of platforms and is about to hit the beta test phase. So if you're writing a C++ application that needs to connect to a MySQL Server, give it a try! The developers are always looking for feedback.
More information and examples on how to use it can be found on this detailed Wiki page on the MySQL Forge.
