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. Refer to Interactive SQL for JDBC (JDBCISQL) for details.
  
• 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. Refer to RegisterStatementPoolMonitorMBean for details.

CHANGED BEHAVIOR

• The installer program now requires you to install a JRE that is Java SE 11 or higher before running the installer. In earlier versions, the JRE used by the installer program was included in the product. However, to avoid potential security vulnerabilities, the installer program no longer includes a JRE. Instead, the installer program uses the JRE in your environment to allow for the most secure version of a JRE to be used.*
  Note: This change does not affect the JVM requirements for the driver. For the latest driver requirements, refer to the Product Compatibility Guide.

• 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.

Version 5.1.4

ENHANCEMENTS

• Support for result set holdability has been added to the driver.
