Batch updates now supported (thanks to some inspiration from Daniel Rall).
XADataSource/ConnectionPoolDataSource
code (experimental)
PreparedStatement.setAnyNumericType() now
handles positive exponents correctly (adds
+ so MySQL can understand it).
DatabaseMetaData.getPrimaryKeys() and
getBestRowIdentifier() are now more
robust in identifying primary keys (matches regardless of
case or abbreviation/full spelling of Primary
Key in Key_type column).
