WPA requires an AirPort Extreme base station and AirPort Extreme or AirPort clients running Mac OS X v10.3, or later. Use of Wi-Fi Protected Access (WPA) reduces the maximum number of network users. Computers with wireless cards that only support WEP cannot join an AirPort network that has WPA enabled.
This update contains new AirPort Extreme features including improved antenna output control, enhanced logging from your base station which is compatible with syslog, and several performance improvements for WPA security implementations.
