Time-based license stacking: Customers can extend time-based licenses such as Botnet Traffic
Filter and SSL VPN Burst by applying multiple licenses.
Licensing of high-availability pairs: For several features, the requirement to deploy identical
licenses on the standby unit in a high-availability pair has been removed. Security Plus licenses
must still be purchased for both the Active and Standby units.
