Mais uma no Mac Rumors:

Reliable sources indicate that Apple has released new builds of Mac OS 10.4.10 for testing. The build versions are reported as 8R208 for PowerPC and 8R2208 for Intel.

Areas of change include fixes involving Image RAW, WebCore JavaScript, and ImageCapture. Previous seeds had also addressed issues with mds and network home directories, and an issue with BSD.

MacRumors first posted that Mac OS 10.4 "Tiger" would receive another minor update on May 17th, with the first seed (8R205 PPC / 8R2205 Intel) showing up a day later.

Pelo que eu sei isso já está confirmado. É só uma questão de tempo para estar disponível.
