According to a Digg.com story, Apple has seeded OS 10.4.8 Build 8L2125 to developers. According to the poster (named "appledev"), no significant issues remain which could indicate a release within days.

The Intel Version weighs in at 206 MB, with the PowerPC Version weighing in at a significantly less 30.8 MB. Previous rumors indicated significant work was being done on Rosetta, which could explain the substantial size difference (although Intel versions have typically been larger, as Mac OS 10.4.7, released in June, was 133 MB Intel and 64 MB PPC).

Other previous (unconfirmed) rumors have indicated that, among other enhancements and bug fixes, OpenGL may have also seen performance improvements.
