If you are upgrading from an earlier release of SAP Sybase IQ, several new features and functionality
introduced in the initial 16.0 version are backward compatible.
GRANT/REVOKE Syntax
The syntax to grant and revoke system privileges in the role-based security model has changed significantly.
Role-Based Security in Stored Procedures
The enhanced role-based security model of SAP Sybase IQ 16.0 retains backward compatibility with authority-based syntax.
