Version 5.1.4

ENHANCEMENTS

• The driver has been enhanced to support the Generic Security Standard (GSS) 
  plug-in for authentication. The plug-in consists of a set of APIs that you can
  implement to customize your authentication requirements and interoperate with 
  various security methods. You can configure a GSS plug-in using the refreshed 
  AuthenticationMethod property and the new GSSPluginName and GSSPluginObject properties. For details, refer to AuthenticationMethod, GSSPluginName, and GSSPluginObject.*
• The driver has been enhanced to support connecting to a proxy server through
  an HTTP connection. HTTP proxy support is configurable with the new 
  ProxyHost, ProxyMode, ProxyPassword, ProxyPort, and ProxyUser connection 
  properties. For details, refer to Connection Properties.*
• The KeepAlive connection property has been added to the driver. Enabling the
  KeepAlive property allows the client to keep idle TCP connections active by periodically passing packets to the server. For details, refer to KeepAlive.*
• The driver has been enhanced to support Windows Defender Credential Guard when using Kerberos Authentication. For details, refer to Configuring Kerberos Authentication.*
• 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.*
• Support for cursor type OUT parameters for DB2 for Linux, UNIX, Windows stored procedures has been added to the driver.*
• The connection properties RandomGenerator and SecureRandomAlgorithm have been
  added to the driver.
  • RandomGenerator allows you to specify the type of random number generator (RNG) the database uses for secure seeding.
  • SecureRandomAlgorithm can be used to specify the SecureRandom number generation algorithm used for secure seeding with implementations of JDK 8 or higher when RandomGenerator is set to secureRandom.
  For details, refer to RandomGenerator and SecureRandomAlgorithm.
• The CryptoProtocolVersion connection property has been added to the driver. This property can be used to avoid vulnerabilities associated with SSLv3 and SSLv2, including the POODLE vulnerability. For details, refer to CryptoProtocolVersion.
• Support for result set holdability has been added to the driver.

CHANGED BEHAVIOR

• For DB2 for z/OS, the AlternateID connection property has been modified to set the name of the schema in the DB2 CURRENT SCHEMA special register instead of the DB2 CURRENT SQLID special register. AlternateID now sets the name of the schema in the CURRENT SCHEMA special register for DB2 for i, DB2 for Linux/UNIX/Windows, and DB2 for z/OS. For details, refer to AlternateID.*
• 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. For details, refer to RegisterStatementPoolMonitorMBean.*
