This is a patch release primarily for fixing below issues in JDBC driver. You don't have to upgrade if you're using Java client.
continueBatchOnErrorwas ignored in Statement.executeBatch()- executeQuery() may return null
- PreparedStatement.executeUpdate() did not work for insert statement using input function
- Exception was swallowed in Statement.executeUpdate() - #836
In addition, exception handling is improved along with some minor changes:
- support largeMaxRows, largeUpdateCount and executeLargeBatch
- disable
execute(*),executeQuery(*),execute*Update(*), andaddBatch(*)methods in PreparedStatement to follow JDBC standard - throw BatchUpdateException instead of SQLException in execute*Batch method
- empty batch is no longer allowed - addBatch is a required before execute*Batch
- query in batch is not allowed, according to JDBC standard
- mixed use of addBatch and execute / executeQuery / execute*Update is not allowed
- ported some IO classes from 0.3.3 branch for slightly improved performance
