Apple has posted both an update (1.2) to its AirPort software and an invite to AirPort users to take part in a survey.

The update makes AirPort more stable. It also supports closed networks, which means the name of the network can be hidden. It’s available from Apple’s updates site.

AirPort 1.2 has a revised default configuration, which does not distribute IP addresses, or share a single address on ethernet, and disables AirPort-to-Ethernet bridging. These settings can be changed in the Network tab of the AirPort Admin utility.

Apple has also released an International English update, Printer Sharing 1.0. This allows USB printers to be shared by multiple Macs using Transport Control Protocol/Internet Protocol (TCP/IP) on Ethernet and wireless networks.
