Version 6.0.0

ENHANCEMENTS

• The driver has been enhanced to include timestamp in the Spy and JDBC packet
  logs by default. If required, you can disable the timestamp logging by
  specifying the following at connection: For Spy logs, set
  spyAttributes=(log=(file)Spy.log;timestamp=no) and for JDBC packet logs,
  set ddtdbg.ProtocolTraceShowTime=false.
• Interactive SQL for JDBC (JDBCISQL) is now installed with the product. JDBCISQL is a command-line interface that supports connecting your driver to a data source, executing SQL statements and retrieving results in a terminal. This tool provides a method to quickly test your drivers in an environment that does not support GUIs.
  
• Added the RegisterStatementPoolMonitorMBean connection property. Note that the
  driver no longer registers the Statement Pool Monitor as a JMX MBean by default.
  You must set RegisterStatementPoolMonitorMBean to true to register the Statement
  Pool Monitor and manage statement pooling with standard JMX API calls.

CHANGED BEHAVIOR

• Java SE 7 has reached the end of its product life cycle and will no longer receive generally available security updates. As a result, the drivers will no longer support JVMs that are version Java SE 7 or earlier. Support for distributed versions of Java SE 7 and earlier will also end, including IBM SDK (Java Edition).
• If you attempt to execute a DatabaseMetadata API with catalogName filter set as '' (Empty String) against Informix 14.1, the API will return the full list of objects instead of an empty result. All DatabaseMetadata APIs, such as getTables() and getColumns(), which support catalogName as filter are affected by this behavior.
