Fixed DatabaseMetaData.getProcedures() when run on MySQL-5.0.0 (output of SHOW PROCEDURE STATUS changed between 5.0.0 and 5.0.1. (Bug #3520)

Fixed case when no output parameters specified for a stored procedure caused a bogus query to be issued to retrieve out parameters, leading to a syntax error from the server.

Correctly map output parameters to position given in prepareCall() versus. order implied during registerOutParameter(). (Bug #3146)

Added connectionCollation property to cause driver to issue set collation_connection=... query on connection init if default collation for given charset is not appropriate. (Bug #3520)

ServerPreparedStatements weren't actually de-allocating server-side resources when .close() was called.

Don't enable server-side prepared statements for server version 5.0.0 or 5.0.1, as they aren't compatible with the '4.1.2+' style that the driver uses (the driver expects information to come back that isn't there, so it hangs). (Bug #3804)

getProcedures() does not return any procedures in result set. (Bug #3539)

Fixed stored procedure parameter parsing info when size was specified for a parameter (for example, char(), varchar()).

Removed wrapping of exceptions in MysqlIO.changeUser().

getWarnings() returns SQLWarning instead of DataTruncation. (Bug #3804)

Cleaned up detection of server properties. (Bug #3146)

Correctly detect initial character set for servers >= 4.1.0. (Bug #3146)

Support placeholder for parameter metadata for server >= 4.1.2. (Bug #3146)

Added logSlowQueries property, along with slowQueriesThresholdMillis property to control when a query should be considered “slow.”

Added .toString() functionality to ServerPreparedStatement, which should help if you're trying to debug a query that is a prepared statement (it shows SQL as the server would process).

Fixed sending of split packets for large queries, enabled nio ability to send large packets as well.

Enabled callable statement caching using cacheCallableStmts property.

Fixed case when no parameters could cause a NullPointerException in CallableStatement.setOutputParameters().

Added gatherPerformanceMetrics property, along with properties to control when/where this info gets logged (see docs for more info).

DBMD.getSQLStateType() returns incorrect value. (Bug #3520)

getProcedureColumns() doesn't work with wildcards for procedure name. (Bug #3540)
