iMac Software Update 1.0 appears to be graphics-releated

Though Apple's cryptic release notes don't indicate so, it appears that iMac Software Update 1.0, which applies to the Mid-2007 iMacs released earlier this week, contains revisions to various graphics card-related components.

Among the files modified by the update:

/System/Library/Extensions

• ATIRadeonX2000GLDriver.bundle
• ATIRadeonX2000VADriver.bundle
• ATIRadeonX2000GA.plugin
• ATIRadeonX2000.kext
• ATINDRV.kext

/usr/libexec/oah/Shims

• GLEngine.bundle

So essentially, various files for driving the ATI Radeon X2000 card available for the new iMacs and an OpenGL-related bundle file were revised. It's still not clear, however, what graphics bugs were fixed or performance enhancements made.
