It seems that Freedom Scientific has quietly released a third automatic update to JAWS 8.0. Labeled as Build 1171 in the auto update dialogue, its Help > About information indicates Build 1166. After running this new build for approximately 10 minutes now, I have not noticed any significant changes. We are all looking forward to the posting of official information concerning this update.
Update: Subsequent checks for updates in the JAWS Help > Check for Updates dialogue continue to offer Build 1171, while actually downloading and installing Build 1166. Caution is urged at this time until Freedom Scientific makes an official announcement concerning this automatic update.
