Apple has released a firmware update that corrects some problems associated with the iSight camera that is built into their LED cinema displays. Additionally, a couple of updates for Camino and Firefox Beta have been released, so if you use those browsers it's worth updating.
Periodically, the camera in the displays may not be detected by applications that use it (iChat, Photo Booth, etc), and this update addresses this issue. The update is a small 654KB update, and will download to the Utilities folder. From there, run the application and follow the on-screen instructions.
Camino 2.0 adds a variety of features to the browser. I used to use this browser exclusively before Apple introduced Safari (when it was called Chimera), and enjoyed it as the alternative to IE and Firefox for OS X. It's still a great browser, and this latest update improves on a number of its features. Go grab it if you're a Camino fan.
Mozilla's latest version of Firefox Beta is available, which addresses some details with the previous beta including script and third-party plugin integration, as well as support for new fonts, and CSS, DOM, and HTML5 technologies.
