Was there something specific you were looking for?
From reading the developers' commit logs... more compatibility for workbench 1.3 - 3.9 bootable disks, ata driver fixes, fixes to support more memory/accelerator configurations at boot or reset time, support for the new AROS USB wireless driver, some optimizations for gcc-m68k compiling.
Jason was planning on having demo discs ready and more info available for the upcoming AmiWest show.
