Think Secret notes that last week Apple distributed Mac OS 10.4.11 build 8S151/8S2151 for PPC and Intel.
Builds 8S151 (PowerPC) and 8S2151 (Intel) feature a handful of additional fixes, including ones targeted at system hangs at shutdown when unmounting an NFS volume, audio drift glitches, incorrect size reporting on Sun Mass Storage Devices, and more.
However, the site notes that a handful of known issues indicates the build is still a few weeks away at best from general distribution.
