Continuing its recent update spree, Apple released incremental versions of Keynote, Pages, and Numbers (collectively iWork '08), as well as firmware revisions for Intel-based Macs. The updates are available via Software Update or as stand-alone downloads. Unsurprisingly, the company doesn't offer much detail about what's changed other than performance improvements: (31.1 MB download) also addresses issues with builds;  (27.8 MB download) updates the change tracking feature; and  (26.1 MB download) addresses issues with tables.
The EFI firmware updates "improve the performance and reliability of Intel Core 2 Duo processors and fix issues with Boot Camp" and are available for, , , , and  computers. Each installs an application in the Utilities folder (which is located in the Applications folder) that will update the firmware. Remember that doing so can lead to a dead computer if something goes wrong, so be sure you have a backup of your data; downloading Apple's  utility and making a disc from it isn't a bad idea either (although I had no trouble on my MacBook Pro).
