Apple has released another update for the Classic environment, Mac OS 9.2.2.

The 21MB update is currently available for download from Apple using the Mac OS 9 Software Update Control Panel. It's also available from Apple's Software Updates Web site.

Apple's notes about the upgrade read: "The Mac OS 9.2.2 Update improves Classic application compatibility in Mac OS X and delivers updated support for Macintosh systems based on the PowerPC G3 or G4 processor."

There are also some changes in the folder structure in Mac OS 9.2.2, making it easier to find files and applications. The Apple Extras and Utilities folders are in the Applications (Mac OS 9) folder; as are Netscape Communicator and Internet Explorer.

The existence of Mac OS 9.2.2 first came to light when Apple announced Final Cut Pro 3 on Tuesday. Then, notes on Apple's Final Cut pages mentioned that its video editing application worked best with Mac OS 9.2.2, which remained unavailable at that time.
