Meanwhile, the new Panther Client upgrade is available for a shipping and handling fee ($19.95) through the Mac OS Up-To-Date program for: 1) all customers who have purchased a PowerMac G5 (regardless of purchase date), 2) all purchasers of any new Mac after October 8th, 2003, or 3) anyone who has purchased Jaguar (Mac OS X 10.2) after October 8th.
Word that Mac OS X (10.3) had hit "Gold Master" first appeared last week, while hints at an October 24th release was first noted by a Page 2 rumor and recently confirmed. Finally, a last minute rumor on Monday had predicted today's official announcement.
