AirPort Software 4.2 for Mac OS X available now

If you're running Mac OS X 10.3.3 through 10.3.9 (update: or 10.4.x), run software update right now to get Apple's AirPort v. 4.2, which "fixes connection problems and resolves security issues with WPA2 wireless networks." You can also download the update from Apple website: Panther  |  Tiger

This update fixes compatibility with Wi-Fi Protected Access (WPA2) security software on AirPort Express and AirPort Extreme base stations. It also resolves IPv6 link local configuration issues.

If AirPort 4.2 solves any of your problems, or creates new ones – let us know in the comments!

Updated to add link to Tiger update, which I swear wasn't there when I looked and I happen to be running Panther on this particular Powerbook in Boston, so I wasn't sure!
