New limitation added to NP7 and NP7Lite traffic shaping limitations: Changes to outbandwidth or egress shaping profiles on a physical or VLAN interface do not take effect for IPsec tunnels or sessions that are already established and offloaded by NP7 or NP7Lite (SOC5) processors. To apply the updated egress shaping settings, you must flush or reinstall the affected IPsec SAs and clear any offloaded sessions. Doing this rebuilds the IPsec tunnel and associated sessions using the new interface shaping configuration.

New section: FortiGate 3800G and 3801G fast path architecture.

Updated Software switch interfaces and NP processors to explain that NP processors support offloading software switch traffic if intra-switch-policy is set to explicit and you have created firewall policies to allow traffic between interfaces in the software switch.
