Bug Fixes for MySQL Connector/J

Version 5.1.13 of Connector/J is out now.

MySQL Connector/J is the official JDBC driver for MySQL.

This update fixes bugs found since the release of 5.1.12. Previously, a load balanced Connection object with multiple open underlying physical connections sometimes rebalanced without validating the existing connection, and the rollback() method would not rethrow a SQLException if the server became unavailable during a rollback. These issues, amongst others, have been rectified. For a full run-through of bug fixes, please see the Changelog.
