Up-to-date wireless region and country codes.
The default country code of region code "E" is changed to "DE" (Germany).
REST API enhancements: supports more statistic information about wireless station Tx/Rx datarate, MCS index, Client Health Metrics, 802.11k/v/r capability, security mode, MPSK, and airtime fairness.

Note: FortiGate needs to run FortiOS version 7.0.0 and later.

Special notices

New Wi-Fi 6/802.11ax models FAP-431F, FAP-433F and FAP-231F initially supported as in FortiAP-W2 6.4.0 release have been moved to FortiAP 6.4.3 and later for continuing support.
FAP-221E/223E units encounter a specific upgrade issue when connected with HPE PoE switches (refer to Bug ID 643738). Those switches can unilaterally reset/power cycle connected FAP units after not receiving any LLDP response for more than 120 seconds. HPE PoE switch users must first disable LLDP function on the switches before upgrading the FAP units. After all FAP units have been successfully upgraded to firmware version 6.4.3 (or later), LLDP function on the switches can be enabled.
